Thanks a lot for your help. Sorry for late reply, but I gave your trick a try and it did not work: ``` /home/xclaesse/programmation/inline-example/builddir/../foo.h:7: multiple definition of `g_strcmp0'; libfoo.dll.p/foo.c.obj:/home/xclaesse/programmation/inline- example/builddir/../foo.h:7: first defined here ```
Updated the test case there: https://gitlab.gnome.org/xclaesse/inline-example Regards, Xavier Claessens.
