Problem compiling string echo

I'm trying to compile the sample file and get this error
while using Centos5
gcc stringecho.c -O3 -Wall -swc -o stringecho.swc
/usr/local/alchemy/bin/llvm-gcc4-ubuntu-install/bin/../libexec/gcc/i686-pc-linux-gnu/4.2.1 /cc1:

(required by
/usr/local/alchemy/bin/llvm-gcc4-ubuntu-install/bin/../libexec/gcc/i686-pc-linux-gnu/4.2. 1/cc1)
This is my bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin:/usr/local/flex_sdk_3/bin

ALCHEMY_HOME = /usr/local/alchemy
#export JAVA_HOME=/usr/local/java/bin/java
PATH=$PATH:$JAVA_HOME:/usr/local/java/bin
source /usr/local/alchemy/alchemy-setup
PATH=$PATH:/usr/local/alchemy/achacks
Any suggestions?

This is because the compiler is using the wrong libstdc++.so.6. You need to use the one that comes with alchemy. I had the same problems on gentoo but finally got it working with this.
ALCHEMY_HOME=/tmp/alchemy-ubuntu-v0.5a #wherever you installed alchemy
export LD_LIBRARY_PATH=.:$ALCHEMY_HOME/bin/llvm-gcc4-ubuntu-install/lib
Took me a while to figure this out so I am posting for others.

Having problems compiling *.java with import javax.servlet.jsp......

I've been trying to do the tutorials in a book titled Apache Jakarta-Tomcat as part of my introduction to JSP. I'm new to Java but do know the basics. I have on my machine Java 1.3, Java 1.4, Java FrameWorks 2.1 and Jython 2.1 on Win2000 Pro. So enough about my configuration. I have never worked with packages also.
I downloaded the files from the books site due to the fact I make a lot of typos when hand coding Java (I've become a pretty good debugger of my own code). But everytime I go to compile the *.java I get error messages. So below you will find HelloTag.java and beneath that the error messages that are thrown when I try and compile it. I tested other bits of *.java and have had no problem compiling them. Is there a JSP module I'm missing?
Am I doing something wrong or am I missing something from my configuration.

Well, it looks like you've not got the servlet development kit JAR on your classpath. I think it'll probably be called servlet.jar on your system. Add that to the classpath if it's not already there.
Incidentally, you've bumped into one of the areas Java's slightly lenient - declaring a method that looks like a constructor:
public HelloTag() { }
public void HelloTag() { }The first is a constructor, the second is a normal method. I'm assuming you intended to have the former instead of the latter.
Anyway, hope this helps.

Having problems compiling script

I am rather new to java an started a couple of days ago and I ran into a problem compiling this script in the command line
class VariableDemo {
public static void main (String args[]) {
int num = 1000;
System.out.println (num + " is the value of num") ;
At first I forgot to capitolize the 'S' in System (which is why I was getting errors) but after I had corrected it , I still could not get it to compile in a command prompt
even after I corrected my mistakes, I still get this error:
error: cannot read: VariableDemo.java
1 error
When I ran it through JCreator it compiled it just fine and found no errors. SO I just want to know if it is some thing that has to do with the command line or is there an error I am not seeing?
I am running Windows XP Pro with service pack 2 and using JCreator 3.50.010

Sorry, I am new to this I just called it script out of ignorance, but, yes it is in the same directory. I even Pathed it out again to be sure.

From your error, it looks like you have not escaped the backslash in the path to J2EE 1.4 beta.
Note: On Windows, while writing the paths in the build.properties files, you need to escape the "\" properly by using "\\" instead. For example, to set j2ee.home to c:\j2sdkee1.4, the entry in the properties file is j2ee.home=c:\\j2sdkee1.4.

Problem compiling Abstract class

Hi
I have writting an abstract class Sort.java and another class BubbleSort.java. I am having problems compiling BubbleSort.java class.
The following is the error message
BubbleSort.java:8: missing method body, or declare abstract
public int doSorting(int[] array);
^
BubbleSort.java:11: return outside method
return num;
^
The following is the code
public abstract class Sort
public abstract int doSorting(int[] array);
}// End of class
public class BubbleSort extends Sort
private int num = 2;
public int doSorting(int[] array);
num = num + 2;
return num;
} // end of class

Remove the semi-colon.
public int doSorting(int[] array); // <------- there

Problem with String variable

I am new to Java Programming.
I have a line of code that works and does what is supposed to.
faceData.getProfile("Lisa").removeFriend("Curtis");
If I assign the strings to variables such as-
String name = "Lisa";
String fName = "Curtis";
and then plug those into the same line of code, it does not work
faceData.getProfile(name).removeFriend(fName);
What could be causing the problem?
I even added some lines to print out what is stored in the variables to verify that they are what they should be, but for some reason the variables do not work while putting the strings in quotes does. Any ideas?

I guarantee that something about your assertions are incorrect. Those variables are either not equal to the values you claim, or something else is going on. But it's not a problem with string variables versus string constants.
Edit: My best guess in lack of a real example from you, is that the strings in question have non-printable characters in them, such as trailing spaces or line feeds.

Little problem with Strings.

          I have an little problem with Strings, i make one comparision like this.
          String nombre="Javier";
          if( nombre.equalsIgnoreCase(output.getStringValue("CN_NOMBRESf",null)) )
          Wich output.getStringValue("CN_NOMBRESf",null) is "Javier" too, because I display
          this before and are equals.
          What I do wrong?.


You are actually making your users key in things like
"\026"? Not very user-friendly, I would say. But
assuming that is the best way for you to get your
input, or if it's just you doing the input, the way to
change that 4-character string into the single
character that Java represents by '\026', you would
use a bit of code like this:char encoded =
(char)Integer.parseInt(substring(inputString, 1),
16);
DrClap has the right idea, except '\026' is octal, not hex. So change the radix from 16 to 8. Unicode is usually represented like '\u002A'. So it looks like you want:String s = "\\077";
System.out.println((char)Integer.parseInt(s.substring(1), 8));Now all you have to do is parse through the String and replace them, which I think shouldn't be too hard for you now :)

Problems compiling Zaptel package [SOLVED-ISH]

Hey guys, I'm on an Arch64 system and I'm having problems compiling Zaptel (a dependancy for Asterisk).
Here's the pastebin of the errors I get from the Zaptel makefile: http://pastebin.com/776475
Here's my analysis so far:
There's a line in the Makefile for the zaptel driver that goes like this:
make -C /lib/modules/2.6.17-ARCH/build/ SUBDIRS=/home/woogie/zaptel/src/zaptel-1.2.8 modules
This line activates the kernel's makefile in order to build modules, but specifies that the source directory for zaptel should be included in the make process.
Then things go down the proverbial drain - linux/err_kernel_only.h gets included in the build process, which is designed to do one thing only - stop the build process. So I'm not entirely too sure what's going on here. Is there something misconfigured on my system, or is the Zaptel build system flawed somehow, such that I need to compensate for it?

Further information:
I've manually run the problematic make command from /lib/modules/2.6.17-ARCH/build on my own. After reading the kernel makefile documentation, I've learned of the V=1 flag to show me exactly what's going on. The failing command is this one:
gcc -Wp,-MD,/home/cestus/zaptel/src/zaptel-1.2.8/.zaptel.o.d -nostdinc -isystem /usr/lib/gcc/x86_64-unknown-linux-gnu/4.1.1/include -D__
KERNEL__ -Iinclude -include include/linux/autoconf.h -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -O2
-fomit-frame-pointer -m64 -mno-red-zone -mcmodel=kernel -pipe -fno-reorder-blocks -Wno-sign-compare -fno-asynchronous-unwind-tables -fun
it-at-a-time -mno-sse -mno-mmx -mno-sse2 -mno-3dnow -Wdeclaration-after-statement -Wno-pointer-sign -I. -Iinclude -O4 -g -Wall -DBUILDING_T
ONEZONE -m64 -DSTANDALONE_ZAPATA -DZAPTEL_CONFIG="/etc/zaptel.conf" -DHOTPLUG_FIRMWARE -I/home/cestus/zaptel/src/zaptel-1.2.8//include
-I/home/cestus/zaptel/src/zaptel-1.2.8//include/oct6100api -DMODULE -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(zaptel)" -D"KBUIL
D_MODNAME=KBUILD_STR(zaptel)" -c -o /home/cestus/zaptel/src/zaptel-1.2.8/zaptel.o /home/cestus/zaptel/src/zaptel-1.2.8/zaptel.c
I've figured out that the bit which causes the failure is "-include include/linux/autoconf.h", because autoconf.h just includes the "err_kernel_only" header automatically, which then slays the build process. And I've also discovered that the Zaptel devs are uber-leet. They've found the magical -O4 level in gcc. You know, the one above 3, where the supported optimization levels in gcc are -O, -Os, -O2 and -O3

Problem compiling Java on XP

i'm new to java, just went through the tutorial just now..
tried compilling my program the first time on XP, but the system doesn't recognise the command JAVAC,
i've installed the java compiler (j2re-1_4_1_01-windows-i586.exe)
but it still isn't working.. any help?
thanks!

then again.. i'm still having problems compiling..
i managed to install the right sdk, but.. i have to run the command javac from the bin directory.. else the command prompt won't recognise it..
anyway to get around this?
also.. because of this.. i can't compile my program.. :(

Problem with String to Int conversion

Dear Friends,
Problem with String to Int conversion
I am having a column where most of the values are numeric. Only 4 values are non numeric.
I have replaces those non numeric values to numeric in order to maintain the data type.
CASE Grade.Grade WHEN 'E4' THEN '24' WHEN 'E3' THEN '23' WHEN 'E2' THEN '22' WHEN 'E1' THEN '21' ELSE Grade.Grade END
This comes the result as down
Grade
_0_
_1_
_10_
_11_
_12_
_13_
_14_
_15_
_16_
_17_
_18_
_19_
_2_
_20_
_21_
_22_
_23_
_24_
_3_
_4_
_5_
_6_
_7_
_8_
_9_
Refresh
Now I want to convert this value to numeric and do some calculation
So I changed the formula as below
cast (CASE Grade.Grade WHEN 'E4' THEN '24' WHEN 'E3' THEN '23' WHEN 'E2' THEN '22' WHEN 'E1' THEN '21' ELSE Grade.Grade END as INT)
Now I get the following error

Dear Kart,
This give me another hint, Yes you are right. There was one row which returns neither blank nor any value.
I have done the code like following and it works fine
Thanks again for your support
Regards
Code: cast (CASE (CASE WHEN Length(Grade.Grade)=0 THEN '--' ELSE Grade.Grade END) WHEN 'E4' THEN '24' WHEN 'E3' THEN '23' WHEN 'E2' THEN '22' WHEN 'E1' THEN '21' when '--' then '-1' ELSE Grade.Grade END as Int)

Problems compiling at91 driver for samutils-0.2.1

Thanks for your help in advance

Thank you for the reply, I noticed that the post below (its for Ubuntu) shows the gcc version to be 4.0.3
[link]http://www.makingthings.com/documentati … -sam7utils[/link]
I poked around the Makefile in /usr/src/linux-2.6.39 and got rid of "-Wall" and "-Wno-implicit-function-declaration"
it compiled with the following warnings:

but when I tried to install, the output was
insmod: error inserting 'at91.ko': -1 Unknown symbol in module
Unfortunately, I tried grabbing the package from the AUR, but I ran into the same issues. Seems the only common factor in this process is gcc.
Thanks for the help

Problems compiling with packages

Hi,
I wonder if anyone could help me.
I have had problems compiling using a package. I have altered the classpath in autoexec.bat with:
SET CLASSPATH=%classpath%;C:\jdk1.3.1_02\classes;.
the package class files are stored in C:\jdk1.3.1_02\classes\helliker\id3
and I have imported the class with:
import helliker.id3.*;
I am getting the following error:
C:\My Documents\Uni work\mp3 project\test\Driver.java:1: package helliker.id3 does not exist
import helliker.id3.*;
^
Can anybody help?
Thanks,
Dave

Perhaps the version of Windows you are using does not use autoexec.bat. For example, in NT and XP, you set Classpath using ControlPanel/System/Advanced/Environment Variables.
Perhaps there is a typo in your Classpath, for example an extra space.
On a command line, try this:
javac -classpath C:\jdk1.3.1_02\classes C:\My Documents\Uni work\mp3 project\test\Driver.java
If that works, then definitely Classpath is not set as you think it is.

Compile string for compile form fmb file in App server 10g

Hi Friends,
I send an email to user to request compile files(fmx) with source code directory in server side.
But user ask me "Where is the compile string and how to I execute it"
also user send below info as
/u01/as10g/as_home/bin/f90genm userid=myproj/password@myprojnew2 module=/u22/apps/myproj/fmb/biweekly module_type=form compile_all=yes upgrade=yes
What means ? Where are can I find a compile string?
Thanks for help!!!

I believe you are the other end of the conversation I've been having with user589812. Please see my entry about using the 10gR2 compiler instead of the 10gR1

Problems declaring string array.

I am having a problem declaring string arrays in a class that I am writing now. For some reason this code won't work:
public class rotors()
String[] rotor = new String[5];
rotor [0] = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
rotor [1] = "ACEGIKMOQSUWYBDFHJLNPRTVXZ";
rotor [2] = "BDFHJLNPRTVXZACEGIKMOQSUWY";
rotor [3] = "AEIOUYBCDFGHJKLMNPQRSTVWXZ";
rotor [4] = "BCDFGHJKLMNPQRSTVWXZAEIOUY";
}//end rotorsOn the other hand, this code will:
public class rotors()
String[] rotor={"ABCDEFGHIJKLMNOPQRSTUVWXYZ","ACEGIKMOQSUWYBDFHJLNPRTVXZ","BDFHJLNPRTVXZACEGIKMOQSUWY", "AEIOUYBCDFGHJKLMNPQRSTVWXZ", "BCDFGHJKLMNPQRSTVWXZAEIOUY"};
}//end rotorsI've noticed that the first code block that I posted will work, but only if I post it in a method, but not just hanging out in the class. Can anyone tell me why this is so? It seems odd to me that the first code doesn't work while the second one does. Thanks a lot

You can initialize a newly declared variable outside of a method/constructor/initializer block, but you can't call other statements outside of these blocks. The rotor array is declared here: String[] rotor... and can only be initialized (if at all) on this line.
