I replaced fbFinishScreenInit with wfbFinishScreenInit (couldn't find fbScreenInit, but from what I understand that function just calls fbSetupScreen and fbFinishScreenInit while the wfb equivalent calls fbSetupScreen and wfbFinishScreenInit), setup a skeleton setupWrap/finishWrap (haven't quite understood what to do with these yet) and added libwfb.la to the make file lib list. But when I try to compile I get errors like: ../../../fb/.libs/libwfb.a(libwfb_la-fbscreen.o)(.text+0x304): In function `wfbSetupScreen': : undefined reference to `wfbInitializeColormap' ../../../fb/.libs/libwfb.a(libwfb_la-fbscreen.o)(.text+0x30c): In function `wfbSetupScreen': : undefined reference to `wfbInstallColormap' As far as I understand they're supposed to be in libwfb.a?
