• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Wojciech Jaskowski 2005-10-14 02:59:23 UTC]

When try to compile program (g++) with -lCg linker says that installed library
is incompatible.


Reproducible: Always
Steps to Reproduce:
1. emerge nvidia-cg-toolkit
2. download sample code from
http://sourceforge.net/project/showfiles.php?group_id=104004&package_id=117303&release_id=245078
3. try to compile the program:  g++ -lCg -lCgGL -lGL -lglut -lGLU -pthread
helloGPGPU.cpp -o helloGPGPU

Actual Results:  
/usr/lib/gcc/x86_64-pc-linux-gnu/3.4.4/../../../../x86_64-pc-linux-gnu/bin/ld:
skipping incompatible /usr/lib/../libCg

[Comment 1 Wojciech Jaskowski 2005-10-14 03:00:02 UTC]

Workaround: Download Cg toolkit from Nvidia site.

Can you let us know which version you tried that doesn't work on amd64?

Thanks!

There's no such thing like libCg in portage, reopen w/ ebuild name and version that installs this library.

nvidia-cg-toolkit, as I stated in "Steps to Reproduce". I don't remember the version. It was nearly a year ago when I submitted the bug! Then it was the latest version.

[Comment 5 Jakub Moc (RETIRED) 2006-09-21 10:27:56 UTC]

So hmmm, can you test w/ something up-to-date? 1.4.0.4 or 1.4.1
