linking libraries

[JustaStudent]

Ok, now to the next problem.. This should fit under the same topic.

I want to build a static executable with this vortex library included. I have tried putting "static" in my "CONFIG +=" in my .pro file, but that just makes no difference. (same size of executable, and not working on other machine with same distro)

Do you have a static version of that library?

[JustaStudent]

no, not that i know of.
the library is compiled with --enable-static but I dont know where the static library is installed..

[jacek]

If you don't have a static version of that library you can't link statically with it. Look for libvortex.a or something similar on your filesystem.

Found it!

/usr/local/lib/libvortex.a

how do i now compile my Qt project with this statically?

(thanks for the help, btw! you seem to really know this stuff.)

[jacek]

If you use pkg-config, then try changing --libs to --static.

[JustaStudent]

I changed the libs in project settings from "$$system(pkg-config --libs vortex)" to "--static $$system(pkg-config --libs vortex)"

Now I get this error message;

/usr/bin/ld: cannot find -lqt-mt

[jacek]

Now I get this error message;

/usr/bin/ld: cannot find -lqt-mt

It looks like it tries to link statically with Qt.

Try:

-static $$system(pkg-config --libs vortex) -dy

[JustaStudent]

I tried the -dy switch, still the same. I want also Qt libraries to be static. I have /usr/local/qt/lib/libqt-mt.a already so that should be possible
