First off, I know that there is a devel mailing list but I really prefer using forum. I guess I'ma kind of 'user++' ie a user with some basic coding knowledges. Whatever I am, I think anyone wanting to help wine is welcome so here I am. I would like to call X11DRV_VkKeyScanEx function but the linker does not know where to find it. I have a dlls/winex11.drv/winex11.drv.so file but adding '-L PATH_TO_X11DRV -I PATH_TO_X11DRV' to winegcc does not solve the problem. Should I include a specific header ? The x11.drv.spec file contains a line defining the function but I never used these files. Some help would be greatly appreciated. Thanks in advance
