Apple Match-O Linker Error

I am making a menu bar app and it is going fine and all but I get an error saying "clang: error: linker command failed with exit code 1 (use -v to see invocation)" here it is in more detail:
duplicate symbol _OBJC_METACLASS_$_View in:
 /Users/Tom/Library/Developer/Xcode/DerivedData/PowerBar-exvfuprqkuwxevgldxdbgyr ypvlx/Build/Intermediates/PowerBar.build/Debug/PowerBar.build/Objects-normal/x86 _64/AppDelegate.o

clang: error: linker command failed with exit code 1 (use -v to see invocation)
So basically I am trying to make a custom veiw and get this error. I know it has something between the Veiw.m file and the AppDelegate.m file because when I remove to #import "Veiw.m" at the top of AppDelegate.m the error is gone. Here is my relevent code:
//Veiw.m
#import "View.h"
@implementation View
- (void)mouseDown:(NSEvent *)event
 NSLog(@"mouseDown");
@end
//Veiw.h (Some stuff is // out so I didn't include it)
#import <Cocoa/Cocoa.h>
#import "AppDelegate.h"
@interface View : NSControl {
@end
//AppDelegate.m
#import "AppDelegate.h"
#import "View.m"
@implementation AppDelegate
@synthesize aboutWindow;
//AppDelegate.h
#import <Cocoa/Cocoa.h>
#import "View.h"
@interface AppDelegate : NSObject <NSApplicationDelegate>{
Please Help.

I don't know why you keep starting new threads for this. But this will be ny last response
@interface View : NSControl {
@end
//AppDelegate.m
#import "AppDelegate.h"
#import "View.m"
You have a number of problems just in this small section of code.
First why are you subclassing an object you are calling view off of NSControl? Makes no sense. If you want to have a view object it should be a subclass of NSView.
Second why are you importing a .m file?
#import "View.m"
The project I told you I put up in Dropbox had all this worked out for you. What you have show here will not work.
good luck
regards

No I didn't even read through your post, to long.
You said that "No matter what program I try to install, as soon as the installer opens it crashes". Were you talking about the install for this/these 3D programs or ANY program? As it is worded it sounded like ANY program. That tells me there is a problem with your Mac, software or hardware.
Now you say others install programs, which is it. Programs other then the 3D ones install or no programs install?
Could simply be your Mac is to old to run these programs and the installer knows that. You never said what model or year Mac it is.

Invalid sibling link error

I have a 15" PB which gave an "invalid sibling link error" one month ago and I was not able to even repair it using DiskWarrior. I have Apple Care Protection plan, so I sent it for repairs and the repair guys replaced the motherboard as they suspected it was the reason. On return, I reformatted the HD and installed everything from stratch. Everything was working fine till last Saturday morning, when computer would not boot up. So I checked using Disk Utility from PB DVD, and the dreaded "invalid sibling error" came up again. Since I have a bootable backup of the HD, I formatted the HD and tried to load the system on the HD from the backup copy. But the writing of backup using CCC hung up and I had to quit it. After that I was not able to find the HD using Disk Utility from DVD.
I have sent it for repairs again, but can anyone help me understand the core problem here. Since last time they replaced the motherboard, I think they will replace the HD this time around. Is the logic board, motherboard or the HD that is the root cause of the problem?
Powerbook G4 Mac OS X (10.4.7) 100GB HDD, 1.5GB RAM

I had never heard of "invalid sibling link error" until you post, and when I ran a search on it the best explanation I could find is that it is a directory-related problem. See the following (assuming it is correct): http://www.computing.net/mac/wwwboard/forum/2584.html The suggestion there, though, is that DIsk Warrior should be able to fix the problem, and you've already told us that you tried using Disk Warrior on it and it did not work.
Very puzzling. Please post back what happens when you get your PB back from being repaired.
Good luck.

Sibling Link Errors

i recently purchased the Mac Pro which i connected through ethernet to my older Power Mac G4 MDD Dual 1GHZ.
i discovered last week that my Mac Pro reported an error in Disk Utility "Invalid Sibling Link" and that app could not repair the problem. i purchased Disk Warrior 4.0 and installed OS X on another internal drive (i have four connected internally) and successfully repaired the disk. On a lark, i checked the Power Mac G4 and found that it also reported errors which could not be repaired by Disk Utility, but it did not report the "Invalid Sibling Link Error." Disk Warrior failed to repair the disk (and i am waiting for the CD to arrive in the mail to start up from it to try again, reporting that it encountered two overlapped filed on the disk).
This week i ran Disk Utility to find that again, my Mac Pro reported the "Invalid Sibling Link" error. i have searched the web and have a basic understanding of what the error is, and many people have experienced the problem. It appears that the error could lead to the start up disk failing to mount, etc. However, i have not experienced any problems with my drive that have been noticeable to me.
My question is what could be causing me to have this repeated error? Does this indicate an actual hard drive failure? Is there a Mac virus that could cause this? Could it be caused by transfering files over the network or through Apple Remote Desktop?
Any discussion on this would be helpful. Thanks folks.
MacPro Dual-Core 3 Ghz Mac OS X (10.4.9) ATi X1900 XT, NVIDIA GeForce 7300, 5GB RAM, 2.8TB, 20" DEll LCD, 2xViewSonic 17"

Which drive gets the error out of all installed, and
where is it located as far as file name etc. I'm
wondering if it could happen using an application
like FCP or CS2 running under Rosetta. Might want to
map it out and try and isolate it that way. I'd also
look for any hardware issues you can find for that
model of hard drive e.g. failures, etc. My two
cents.
Michael
It is the Startup Drive that gets the error on my Mac Pro (the preinstalled drive that came with the Mac), and the start up drive on the MDD G4. The MDD G4 had two files that were cross linked (a Civ file and an iTunes Temp file) that i had to manually delete before Disk Warrior could repair the drive. On the Mac Pro i have used Photoshop CS (1?) a little, but not to any large degree, other than that, i have used Apple's Pages, Safari, and Office... but nothing task intensive.
i ran Apple's Hardware test which appears to check RAM and the Logic Board and both checked out fine. i used both Disk Warrior and Drive Genius, both report that the S.M.A.R.T. status of the drive is verified and the drive is working properly.
i am curious if Apple Remote Desktop could cause the error? i frequently copy files from one computer to the other... but i can't fathom why or how this would be the case. But it has to be something, else why get this error twice in the space of a week?
i had not considered Tiger Cache Cleaner... i will check that out, but again, i don't know if this will tell me WHAT is going on and WHY it is happening.

JNI Unsatisfied Link Error

Hello All:
I have some java code that calls a C function in a dll. I have succesfully used the javah utility to generate the header file for my jni native implementation code and have build both the client java code as well as the dll using g++3.0 using Bloodshed Dev C++ (an open source IDE). When I go to execute the java code I get an unsatisfied link error saying my function is not recognized by the jvm. Does anyone have any suggestions on this issue?? I am using Win2k and jdk 1.4.1
Here is what I've already tried:
1) Have added the directory where the java class file as well as the dll to my PATH variable, I have even put the dll files in the jdk bin directory
2) My dll loads three other dll's and calls a function in one of those dll's, I am using the loadLibrary function to load these dll's and am using function pointers to reference the actual function in the dll
I was wondering if its a problem if I use g++ to build my dll, does the virtual machine assume by default that gcc is used, please let me know.
Any help is much appreciated
Thanks

I've looked through the various postings on this issue and have tried some or all of the suggestions that were made relevant to my problem but I still keep getting this error. As a result I am attaching some code here:

When I go to execute the java code I get an unsatisfied link error
saying my function is not recognized by the jvm.Presumably this means that you loaded the dlls successfully.
Which means that the shared lib path, at least for those dlls, does not matter. The path only matters when the dll fails to load.
So you are getting this when the native method is actually called.
The reason is because the signatures do no match. Java is calling a JNI method and that exact method is not in the dlls that you have loaded.
Possible reasons:
-You didn't use javah correctly (has to do with packages.)
-You added a package and didn't rerun javah to get the new signature.
-You changed the package and didn't rerun javah to get the new signature.
-You manually modified the signature so it no longer matches the one generated by javah.
-You are using an unusual set of compiler options which causes the compiler to modify the signature.
-You are loading the wrong dll.

Sibling Link Error After Updating Software

Ok, two days ago I updated my imac software. Afterwards, the imac started running slow and freezing (which it never does). I booted through my OS X DVD and ran disk utility, repair HD. It came up with a sibling link error: can't repair drive. Not knowing what to do, I erased my HD and reinstalled Leopard. Everything ran well until I updated my software, then the same problem. At this point I erased my HD (zero out) and reinstalled Leopard with no problems. Again, I ran software update and the same problem happened, sibling link error. So this time, I erased the HD and haven't updated the software. What should I do? Should I not run software update? It appears that the problem (sibling link error) only surfaces when I update my software.

After installing Leopard off the disc (which is where you are at now), try running Disk Utility and using the +Repair Disk Permissions+ routine. Then, run Software Update and only select the 10.5.7 Update on the list of available updates. Run that one update only. After it is done, check to see of you have that same error. If you do not, run the other available updates. When it is all done, run +Repair Disk Permissions+ one more time.
Note: I always run +Repair Disk Permissions+ immediately before I have Software Update install any update.
If you still get that error after the 10.5.7 update, you can try installing Leopard from the disc again, and using the stand-alone updater for installing the 10.5.7 combo update.

the error that you are receiving is most likely due to a name resolution issue...check to see that the name of the report in your enterprise environment matches exactly with the name in the WESubmit formulae.if you're using a december 18th version of the report (date is in the page header PH section) then the name of the report in enterprise should be webElementsBasicFunctionalitynote that having a .rpt extension in the enterprise environment in this case will cause name resolution issues...i.e. webElementsBasicFunctionality.rpt is not the same as webElementsBasicFunctionalityjw

How can I fix an invalid sibling link error message without my original install disk?

How can I fix an invalid sibling link error message without my original install disk?

Hi Jeff,
It's not even likely the Install Disc could fix that, but if you want to try...
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...
http://docs.info.apple.com/article.html?artnum=106214
You must repair the HD, your best bet is likely DiskWarrior.
BTW, you might enjoy these DiskWarrior review/recommendations...

Finally, you should run DiskWarrior if your Mac explicitly warns you of a problem with your disk in the form of an error message. Most of these errors are reported by the built-in Disk Utility whether your Mac OS X version is 10.3 Panther, 10.4 Tiger, 10.5 Leopard, 10.6 Snow Leopard or 10.7 Lion. Here are some of the most common messages:
Disk Repair: The disk was not repairable by this computer. It is being made available to you with limited functionality. You must back up your data and reformat the disk as soon as possible.
The underlying task reported failure on exit.
Invalid node structure.
Keys out of order.
Invalid key length.
Invalid directory item count.
Invalid extent entry.
Invalid record count.
Invalid index key.
Invalid sibling link.

This software cannot be installed on the computer/sibling link error

I have been helping a friend overseas troubleshoot her computer.
http://discussions.apple.com/thread.jspa?threadID=1741148&tstart=0
We are at the point where she was able to get her data off the drive and would now like to reinstall her system.
She has a refurbished iBook which was running 10.4.11 with software updates. Her startup disks are in the states as she is in a village in Africa. She has borrowed disks which contain 10.4.8 and is receiving the message that +"This software cannot be installed on the computer."+ Would this be due to different versions and trying install an older OS onto a computer with a newer OS?
She had a sibling link error on her hard drive, so we were able to recover data. I was hoping to reformat her hard drive to remove the error and reinstall the system. Would this error effect the installation process?
Thank you.

If this is an iBook model she will need to use a retail Tiger installer or the discs that came with her computer. She could try with Leopard if the iBook meets the requirements:

It seems everything from apple is slow even the mobile me sight which i had to discontinue using

Unless you have EE 4G service the UK 3G networks are the base of your problem - they are just far to variable in download and streaming speeds.
Add to the fact that use can/will eat into your Data usage !
ITunes Match as a service is pretty experimental at best over 3G and really i think so long as you have a 32GB or larger iOS device sync'ing via iTunes on a PC/Mac remains the best way to transfer music.
Remember even with iTune Match your music is STILL ON your own PC/Mac HDD !
Usng the devices tab in iTunes you can customize each differing identified iOS device and load as you please.
When we have a competitively priced stable and extensive LTE network in the UK then reconsider Match at that point.

_z_inflateInit_ referenced from symbol missing (zlib linking error)

I am trying to compile a project that uses inflateInit, deflateInit, inflate, deflate, inflateEnd, deflateEnd, which are all from zlib.h... i know i am getting a linking error and it cannot find the implementation of these files. i have included libz.1.1.3.dylib within my project, i have tried including libz.dylib, i have also tried to put the
OTHER_CFLAGS = -lz
none of this has seemed to work. any help would be much appreciated ! ! !
this is the definition for inflateInit and it calls zinflateInit which is also in zlib.h
{#define inflateInit(strm) \
inflateInit_((strm), ZLIB_VERSION, (int)sizeof(z_stream))
ZEXTERN int ZEXPORT inflateInit_ OF((z_streamp strm,
const char *version, int stream_size));
when i build my project, the errors i get are :
z_inflateInit, referenced from:
foo()
zinflate , referenced from:
foo()
symbols(s) not found collect2: Id returned 1 exit status
