Still having issues linking due to command line limitations

[renebarto]

Hi, I posted about a week ago on a problem I had when linking quite a few object files together to an so on Linux (Ubuntu 12.04, running CodeBlocks 13.12, upgraded from 10.05 finally).

My link statement is this:
g++  -L../../../bin/Debug -o ../../../bin/Debug/Core.Test obj/Debug/src/CoreMutexTest.o obj/Debug/src/Main.o obj/Debug/src/CoreWorkerThreadTest.o obj/Debug/src/CoreTimerTest.o obj/Debug/src/CoreTimeStampTest.o obj/Debug/src/CoreThreadTest.o obj/Debug/src/CoreTextWriterTest.o obj/Debug/src/CoreTextReaderTest.o obj/Debug/src/CoreStreamTest.o obj/Debug/external/gtest/gtest-all.o obj/Debug/src/CoreManualEventTest.o obj/Debug/src/CoreCyclicBufferTest.o obj/Debug/src/CoreByteArrayTest.o obj/Debug/src/CoreAutoEventTest.o obj/Debug/src/CoreArrayTest.o obj/Debug/src/CoreActiveObjectTest.o  -Wl,-rpath,'$ORIGIN' -lCore -lrt -lpthread

When building from a makefiles, this works perfectly. However, when I set the linker to echo instead of actually link in CodeBlocks, the output is:
g++  -L../../../bin/Debug -o ../../../bin/Debug/Core.Test obj/Debug/src/CoreMutexTest.o obj/Debug/src/Main.o obj/Debug/src/CoreWorkerThreadTest.o obj/Debug/src/CoreTimerTest.o obj/Debug/src/CoreTimeStampTest.o obj/Debug/src/CoreThreadTest.o obj/Debug/src/CoreTextWriterTest.o obj/Debug/src/CoreTextReaderTest.o obj/Debug/src/CoreStreamTest.o obj/Debug/external/gtest/gtest-all.o obj/Debug/src/CoreManualEventTest.o obj/Debug/src/CoreCyclicBufferTest.o obj/Debug/src/CoreByteArrayTest.o obj/Debug/src/CoreAutoEventTest.o obj/Debug/src/CoreArrayTest.o obj/Debug/src/CoreActiveObjectTest.o  -Wl,-rpath,

This points to a chopping of of the command line. Does this sound familiar? I had the same problem with CB 10.05, but the upgrade to 13.12 does not seem to help.

This is really a pity, as I strongly prefer CB over Eclipse!

If you (temporarily) replace the variable $ORIGIN with its actual value, what happens?

[oBFusCATed]

You have to use \$\$ORIGIN or \$\$\$ORIGIN, I don't remember which worked exactly. This is required because both C::B and the shell escape $ORIGIN as variable and replace it with empty string.

MIght also (unfortunately) be \\$$$ORIGIN.

Hello guys, thanks for your replies, however that does not solved it. Looking deeper into the code, it seems that wxExecute, used to dispatch the commands, has an issues that the command line is limited to something like 255 characters. I haven't looked into the wx library code yet, but will do soon.

It is not at least on linux. It works with way longer command lines.

Hi everyone, I tried a bit more, and you're right, it is not the command line length. I found a post that is giving the answer:

Escaping $ by $`` actually works. I'm also using cbp2make to create makefiles from the cbp projects, and now that has an issue, but I'm trying to fix that.

Anyway, I thought you'd like to know there is a solution.

Regards,

Rene

Interesting hack
