Cannot link to my own libraries in Qt 5.2.0 OSX w/clang++
-
Hi and welcome to devnet,
Are you really sure the libraries are installed (you would need admin rights to install them) ?
Did you check using ls ?
Do they follow the normal naming scheme ?Hope these questions helps

Hi,
They're definitely in the right place. The project was pulled down from a working copy out of SVN. The only thing I can think of is that clang isn't looking in the directory that I'm telling it to.

The command line looks fine to me. Can you try with a minimal project that uses libabcsCore ?
-
What does
@ls -la /usr/lib/libabcsCore*@
return ?

Sorry for taking so long to reply:

I just realized, is it me or is -L/usr/lib missing from your linker line ?
-
I think it might be you. ;-)

Did you try to link to your library by hand on the command line ?
-
No sorry, I meant create a dummy main using a function of your library and call clang by hand to compile/link to see it still has the same problem
