Missing compiler error output

Hopefully this is a simple one:
When I compile a program and there are errors and/or warning, the Build Output window opens, but the error messages are not listed! All it shows is:
Build Status (MyProject.prj - Debug)
MyModule.c
Build failed.
If I click on the "Compile" button 4 or 5 times in a row, finally the list of errors will appear. I can't seem to figure out any logic to when the error list appears or fails, but half a dozen retries eventually gets it there. I've checked all of the compiler settings, and the appropriate warnings are turned on, etc. What am I missing???
I'm using Version 13.0.0 (632)
Thanks
Solved!

Hello Rallyr,
Are you building a project found on a mapped network drive? If so, this post might be of help. If not, could you provide us the details of the project? What configuration are you using? Are you using precompiled headers?
Maybe you could attach a project that reproduces the behavior?
Best regards,

Newbie: jsp compile error w/ tomcat 5.0.19

Hello there, this is my first time try to write something in jsp/ servlets, and i encounter a minor installation problem:
using mdk linux with j2sdk1.4.2 (locate at /usr/local/), tomcat is also locate at /usr/local.
I am able to see HelloServlet.java, and HelloWorld.html at http://localhost:8080/servlet/HelloServlet
and http://localhost:8080/testing/HelloWorld.html
but i'm unable to see HelloWorld.jsp at http://localhost:880/HellowWorld.jsp (my HelloWorld.html and HellowWorld.jsp are locate at the same dir)
here's are the things i added in my /etc/profile so far:
CATALINA_HOME="/usr/local/Tomcat"
export CATALINA_HOME
JAVA_HOME="/usr/local/j2sdk1.4.2"
export JAVA_HOME
JavaPath="/usr/local/j2sdk1.4.2/bin"
export JavaPath
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH
CLASSPATH=$CLASSPATH:/usr/local/Tomcat/common/lib/servlet-api.jar:/usr/local/Tomcat/
common/lib/jsp-api.jar:/home/allen/programming/j2ee/:./
export CLASSPATH
when do java -verison, i see:
[root@localhost local]# java -version
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)
when start tomcat, i got:
[root@localhost bin]# ./startup.sh
Using CATALINA_BASE: /usr/local/Tomcat
Using CATALINA_HOME: /usr/local/Tomcat
Using CATALINA_TMPDIR: /usr/local/Tomcat/temp
Using JAVA_HOME: /usr/local/j2sdk1.4.2
i thought i did everything that was told, yet i can't see jsp page on my browser, while i can see servlets and html,
thank you for your time in advance ^_^

sorry, it was a typo, yea...it was for http://localhost:8080/testing/Hello.jsp
this morning, i copied "tool.jar" from j2sdk1.4.2 to my /usr/local/tomcat/common/lib, restarted, fire it up again using "./catalina.sh" just to see where the problems came from, and here's where the compile error occue:
Compile failed; see the compiler error output for details.

looking over the compiler error, it seems to me tomcat is able to recongize /usr/local/j2sdk1.4 's location. which i assume it implied JAVA_HOME and CLASSPATH are setup correctly.
Dunno why it just won't display jsp pages and kept saying compiler error...
thank you for helping

"asant build" for bookstore1 example in j2ee tutorial gives "compile error"

Hello everybody,
I am trying to run "asant build" command to build package for bookstore1 example given in j2ee tutorials.
I installed my j2ee tutorial 1.4 in "c:\java\j2eetutorial14" and my example is in "c:\java\j2eetutorial\examples\web\bookstore1".
My j2ee SDK with appliation server is installed in C:\sun\appserver.
When i run the "asant build" command in "c:\java\j2eetutorial\examples\web\bookstore1" directory i get compile error with last few lines as follows.

When i run the "asant build" command in
"c:\java\j2eetutorial\examples\web\bookstore1"
directory i get compile error with last few lines as
follows.Did you package the bookstore common files as described in Chapter 3? My guess is that you didn't include bookstore.jar from <INSTALL>/j2eetutorial14/examples/build/web/bookstore/dist/.

C# compiling error: 'System.Array' does not contain a definition for 'Select' and no extension method 'Select' accepting a first argument of type 'System.Array' could be found (are you missing a using directive or an assembly reference?)

Hello experts,
I'm totally new to C#. I'm trying to modify existing code to automatically rename a file if exists. I found a solution online as follows:
string[] allFiles = Directory.GetFiles(folderPath).Select(filename => Path.GetFileNameWithoutExtension(filename)).ToArray();
string tempFileName = fileName;
int count = 1;
while (allFiles.Contains(tempFileName ))
tempFileName = String.Format("{0} ({1})", fileName, count++);
output = Path.Combine(folderPath, tempFileName );
string fullPath=output + ".xml";
However, it gives the following compilation errors
for the Select and Contain methods respectively.:
'System.Array' does not contain a definition for 'Select' and no extension method 'Select' accepting a first argument of type 'System.Array' could be found
(are you missing a using directive or an assembly reference?)
'System.Array' does not contain a definition for 'Contains' and no extension method 'Contains' accepting a first argument of type 'System.Array' could be
found (are you missing a using directive or an assembly reference?)
I googled on these errors, and people suggested to add using System.Linq;
I did, but the errors persist.
Any help and information is greatly appreciated.
P. S. Here are the using clauses I have:
using System;
using System.Data;
using System.Windows.Forms;
using System.IO;
using System.Collections.Generic;
using System.Text;
using System.Linq;

Besides your issue with System.Core, you also have a problem with the logic of our code, particularly your variables. It is confusing what your variables represent. You have an infinite loop, so the last section of code is never reached. Take a look
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
namespace consAppFileManipulation
class Program
static void Main(string[] args)
string fullPath = @"c:\temp\trace.log";
string folderPath = @"c:\temp\";
string fileName = "trace.log";
string output = "";
string fileNameOnly = Path.GetFileNameWithoutExtension(fullPath);
string extension = Path.GetExtension(fullPath);
string path = Path.GetDirectoryName(fullPath);
string newFullPath = fullPath;
string[] allFiles = Directory.GetFiles(folderPath).Select(filename => Path.GetFileNameWithoutExtension(filename)).ToArray();
string tempFileName = fileName;
int count = 1;
//THIS IS AN INFINITE LOOP
while (allFiles.Contains(fileNameOnly))
tempFileName = String.Format("{0} ({1})", fileName, count++);
//THIS CODE IS NEVER REACHED
output = Path.Combine(folderPath, tempFileName);
fullPath = output + ".xml";
//string fullPath = output + ".xml";
UML, then code

Compile Error: missing return statement

anyone knows why the following program yields compile error "missing return statement??"
class LengthTest
     public int stringLength(String s)
     {     int len = s.length();
          if (len <= 5) return 5;
          else if (len <= 10) return 10;
          else if (len <= 20) return 20;
//          else return 30;
If I add "else return 30" statement, then it can stop the error. Any ideas??

You might know that the string length will never be more than 20, but the compiler does not. So it forces you to supply a return statement that will be executed no matter what the string length is.

Flex compilation error after adding an additional output port to a query

Hello,
I need to add an additional output port to a query in order to dynamically filter some results. Our version of VC 7.0 (SP16) doesn't support filter components with access to store data.
Just when we add an extra output port to the query and deploy it we run into a flex compilation error.
Has somebody come along with that?
Kind regards
Stefan

Hi
Why exactly you want another output port. With same output port you can drag multiple filters & restrict the output.
Creation of second output port is not required.
If first way is not suitable in your case, then you add that query twice (or multiple times) & pass the same input parameters.
If still it is not serving the purpose then please elaborate your requirement as what dynamic filter you want.
Regards
Sandeep

This line of code for the begining of a method that reads a file always throws the compiler error, missing return statement. I can't figure out how to fix it!
public String[] read(InputStream list) throws Exception {
Could someone please help?

you might need to post more code, but basically the
compiler is complaining because you do not have a
return statement at the end of your method.
if you do not have a return statement (with a matching
return type) then the compiler will complain. If you
don't understand this then post the code to your
method and we can get it fixed.
public String[] read(InputStream list) throws
Exception {
String[] stringArray;
return stringArray;
The code is the most complex I have written so far but here is some of it. (the begining and the end)
public String[] read(InputStream list) throws Exception {
if (list != null) {
String[] stringArray = null;
try {
while {
//add strings to string array
}//end of while
return stringArray;
}// end try
catch{
}//end of method

A sporadic compile error vbc : error BC31019: Unable to write to output file 'D:\Revit\Dev32\RevitAdditions\Source\..\Intermediate\ReleaseWin32\VBNETSnippets\VBNETSnippets.dll': The specified image file did not contain a resource section.

Hi,
This is developer from Autodesk. We get this compile error from time to time. This is a sporadic failure. We can't find any issue in our own project.
vbc : error BC31019: Unable to write to output file 'D:\Revit\Dev32\RevitAdditions\Source\..\Intermediate\ReleaseWin32\VBNETSnippets\VBNETSnippets.dll': The specified image file did not contain a resource section.
I find a help doc from the website to try some steps to solve this issue.
Error ID: BC31019
To correct this error
Compile the program again to      see if the error recurs.
If the error continues, save      your work and restart Visual Studio.
If the error continues, restart      the computer.
If the error recurs, reinstall      Visual Basic.
If the error persists after      reinstallation, notify Microsoft Product Support Services.
My question is what the root cause for this issue. Could you please give us some explanation where the issue should be, VB compiler? .Net Framework?
Visual Studio? Operating system?
Thanks
Wilson

Hi hitzwx,
Thank you for posting in MSDN forum.
Since this forum is to discuss: Visual Studio WPF/SL Designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help
System, and Visual Studio Editor.
Based on your issue, I am not sure what the root cause for this issue. But I suggest you can try some suggestions so that narrow down this issue.
(1) I suggest you try to create a new simple VB project and then check this issue.
(2) In addition, maybe you see the document about your issue. If possible, I suggest you can try these suggestions to troubleshooting this issue.

>>Unable to write to output file 'D:\Revit\Dev32\RevitAdditions\Source\..\Intermediate\ReleaseWin32\VBNETSnippets\VBNETSnippets.dll': The specified image file did not contain a resource section.
In addition, I suggest you can check if the specified image file in the output folder or you can try to click your image file in the Solution Explorer-> select the Copy to Output Directly properties->Copy always check this issue again.
If you have any update message about your issue, please tell me.

Java Adapter Compile Error - Missing Libraries

I am trying to convert my project from being deployed on Flex Data Services 2 To LiveCycle Data Services. I dont know very much about java and have hit a snag when trying to recompile my custom java adaptor.
It compiles fine under a FDS2 project, but when compiled under a LCDS deployment on JRun, Eclipse gives me the following error when trying to compile:
Project PTSChat_Java is missing required library: lib/commons-codec.jar
Project PTSChat_Java is missing required library: lib/commons-httpclient.jar
The project cannot be built until build path errors are resolved
It appears that the libraries have been renamed to commons-codec-1.3.jar & commons-httpclient-3.0.1.jar in LCDS, but I am not sure where to update these references? They are not direct library imports in my java code.
As a shot in the dark, I tried just copying the old FDS2 libraries back over to the WEB-INF\lib\ DIR since there are named differently. It resolved the missing library error, but then I got a compile error with service cannot be resolved in references to my MessageService msgService = (MessageService) service; java code. I quickly realized this is not the correct path to head down.
Does anyone have any clues what I may be doing wrong? Any help is much appreciated.
Thanks!

I resovled the problems I was having.
I was able to figure out how to change the library linking in eclipse and switched the commons-codec-1.3.jar & commons-httpclient-3.0.1.jar in the place of commons-codec.jar & commons-httpclient.jar libraries previously used with the project (properties:libraries).
I was not able to correct the service cannot be resolved. Everything I did kept crashing and dropping my connection tot he channel. I ended up just switching the code in my java adapter from:
MessageService msgService = (MessageService) service
to
MessageBroker broker = MessageBroker.getMessageBroker(null);
MessageService msgService = (MessageService) broker.getService("message-service");
This appears to be working as desired for my use of the java adapter for the session management & logging. I am not really certain why the "service" became undefined between FDS2 & LCDS, something must have been depreciated or changed around.

Compile error std::pair . Is copy ctor call missed?

#include <vector>
struct A {int a;};
struct B : public A {char b;};
int main()
B b;
typedef std::pair<A*, A*> MyPair;
std::vector<MyPair> v;
v.push_back(std::make_pair(&b, &b)); //compiler error here(pair<B*,B*>)
return 0;
}error : formal argument x of type const std::pair<A*, A*> & in call to std::vector<std::pair<A*,A*> >::push_back(const std::pair<A*, A*> & ) is being passed std::pair<B*, B*>
There should not be any error because 1) std::pair<B*,B*> created 2) std::pair<A*,A*> from 1. copy-created.

The default libCstd is not fully conforming to the C++ standard. In particular, it is missing features that require class member templates. The issue is discussed in the C++ FAQ section on library compatibility:
[http://developers.sun.com/sunstudio/documentation/ss12u1/mr/READMEs/c++_faq.html#LibComp]
You can use the optional STLport library, which has this missing functionality, by adding the option -library=stlport4 to every CC command line, compiling and linking. You cannot mix libCstd and STLport in the same program. If you use STLport, everything must be compiled using STLport, including any libraries linked to your program.

Compiler error: Missing JSP library?

Hi All,
I am really new at this, and I know that I'm making some sort of simple mistake.
I have an existing application running on a 9i middle tier. I want to make a couple of simple changes to a .JSP. So I downloaded the EAR file, loaded it into JDeveloper (10.1.3.0.4 SU4), made my changes and tried to run it locally. I got 241 compiler errors. So I reverted to the original EAR, and I still get 241 compiler errors.
The errors are:
Error(1,5): illegal forward reference
Error(1,14): duplicate definition of class _index
Error(1,48): HttpJsp not found in class _index
Error(1,62): method getPageContext(_index, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, null, boolean, int, boolean) not found in class javax.servlet.jsp.JspFactory
The code is:
<sample>
import oracle.jsp.runtime.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.jsp.*;
public class _index extends oracle.jsp.runtime.HttpJsp {
public final String _globalsClassName = null;
public void _jspService(HttpServletRequest request, HttpServletResponse response) throws java.io.IOException, ServletException {
response.setContentType( "text/html;charset=windows-1252");
/* set up the intrinsic variables using the pageContext goober:
** session = HttpSession
** application = ServletContext
** out = JspWriter
** page = this
** config = ServletConfig
** all session/app beans declared in globals.jsa
PageContext pageContext = JspFactory.getDefaultFactory().getPageContext( this, request, response, null, true, JspWriter.DEFAULT_BUFFER, true);
// Note: this is not emitted if the session directive == false
HttpSession session = pageContext.getSession();
if (pageContext.getAttribute(OracleJspRuntime.JSP_REQUEST_REDIRECTED, PageContext.REQUEST_SCOPE) != null) {
pageContext.setAttribute(OracleJspRuntime.JSP_PAGE_DONTNOTIFY, "true", PageContext.PAGE_SCOPE);
JspFactory.getDefaultFactory().releasePageContext(pageContext);
return;
</sample>
So, I read the forums, etc and decided that I need ojsp.jar included in my project libraries. So I went to libraries under project properties, and I already have "Jsp Runtime" as my first library and it claims to include ojsp.jar. I've tried removing and re-adding the library, adding other libraries ("J2EE","Servlet Runtime","OC4J Deployment Plugin"...), and a dozen other things, none of which have allowed my to compile.
Any ideas on what I should do?
Steven

you might need to post more code, but basically the
compiler is complaining because you do not have a
return statement at the end of your method.
if you do not have a return statement (with a matching
return type) then the compiler will complain. If you
don't understand this then post the code to your
method and we can get it fixed.
public String[] read(InputStream list) throws
Exception {
String[] stringArray;
return stringArray;
The code is the most complex I have written so far but here is some of it. (the begining and the end)
public String[] read(InputStream list) throws Exception {
if (list != null) {
String[] stringArray = null;
try {
while {
//add strings to string array
}//end of while
return stringArray;
}// end try
catch{
}//end of method

Compilation errors with store procedure

Hi guys, I just started SQL so forgive me if I ask any real stupid questions. This is the problem I have right now as said in my title.
This is my procedure.sql
CREATE OR REPLACE PROCEDURE verify IS
no_of_duplicates NUMBER:=0;
BEGIN
SELECT COUNT(*) INTO no_of_duplicates
FROM EMPLOYEE
WHERE E# =
(sELECT E# FROM DRIVER
WHERE EXISTS
(SELECT E# FROM MECHANIC
WHERE DRIVER.L# = MECHANIC.L#));
IF no_of_duplicates:=0 THEN dbms_output.put_line('OK');
ELSE
SELECT E#,NAME FROM EMPLOYEE
WHERE E# =
(SELECT E# FROM DRIVER
WHERE EXISTS
(SELECT E# FROM MECHANIC
WHERE DRIVER.L# = MECHANIC.L#));
END IF;
END verify;
While trying to create the procedure, it gives me the compilation errors. I have been stuck with this for hours and can't seem to find anything wrong with it. Can anyone point me in the right direction? Thanks!

Hi,
Once again, post your code. The error occurs when you call the procedure, but you haven't posted the code that calls the procedure and causes the error.
When I do this in SQL*Plus:
SET SERVEROUTPUT ON FORMAT WRAPPED
EXEC verify;
The procedure you posted runs perfectly (that is, is displays the e# only, exactly as it was designed to do).
One way to display both the e# and the name is to BULK COLLECT both the e# and name into separate collections, like this:
CREATE OR REPLACE PROCEDURE verify IS
    TYPE e#_table IS TABLE OF employee.e#%TYPE;
    e#_list    e#_table;
    TYPE name_table IS TABLE OF employee.name%TYPE;
    name_list name_table;
BEGIN
    SELECT            e#,       name
    BULK COLLECT INTO e#_list, name_list
    FROM              employee
    WHERE   e# IN (
                      SELECT d.e#
                      FROM    driver    d
                      JOIN    mechanic m ON d.e# = m.e#
    IF e#_list.COUNT = 0
    THEN
        dbms_output.put_line ('OK, there are no illict duplications');
    ELSE     -- that is, e#_list.COUNT <> 0
        dbms_output.put_line ('The following employees are both drivers and mechanics:');
        FOR j IN 1..e#_list.COUNT LOOP    -- i in parentheses sometimes displays wrong on the OTN site
            dbms_output.put      ( TO_CHAR ( e#_list (j)
                                           , '999999999999'
            dbms_output.put      ('   ');
            dbms_output.put_line (name_list (j));
        END LOOP;
    END IF;
END verify;
SHOW ERRORS
Here's the output I get when I run the procedure above with your sample data:
The following employees are both drivers and mechanics:
            1   John Smith
You'll notice I made several other changes in your code, sometimes because they are clearly better practices, and sometimes just to show you different ways to do the same thing, which you may or may not want to use in this problem.
For example, you were doing the same query (with only very slight differences) 2 times: once to get no_of_duplicates, and then a second time to get the actual data. I don't know if that's the most efficient way to do what you need. Say there are 1000 rows in the result set. You'll fetch all 1000 once just to get the total number, (which you don't need, if all you care about at this point is if there are any), and then to get the data. When you do a BULK COLLECT, you automatically get the COUNT anyway, so why not do the BULK COLLECT first, then use that COUNT to see what you have to do next. If the COUNT is more than 0, then you've already got the data, and you don't need to fetch it again. Also, repeating (essentially) the same code is a maintenance problem. If you ever need to make a change, you need to make the same change in multiple places. At best, that's a pain; but this is the exactly the kind of mistake that is easy to miss in in testing, and you might have code running for weeks in Production before you notice that sometimes it's giving the wrong results.
Another example: e# is a NUMBER. While it is possible to convert NUMBERs into VARCHAR2s, and then store those VARCHAR2s in a VARCHAR2 collecction, wouldn't it make more sense just to store them in a NUMBER collection?
