Unable to link .so file

[A Former User]

I have .so files (myLib.so, myLib.so.1, myLib.so.1.0, myLib.so.1.1.0) which I copied to my executable's directory. In project settings I added

@LIB += -lmyLib@

and also set the LD_LIBRARY_PATH to point to where my .so files are located.

I also tried

@LIB += -L/home/me/ProjectFolder/-lmyLib@

I always get this error:

(.text.startup+0x39):-1: error: undefined reference to `MyLib::Test()'

How can I use the .so file?

Maybe because your lib fails linux library naming convention?
-l<libname> means what the linker should search for lib<libname>.{a.so} and link it.
-lmyLib - will search for libmyLib.{a.so}, and if your library name is myLib.so it will fail...

You can try to point to the library file directly:

@
LIB += /home/me/ProjectFolder/myLib.so
@
