| |
There is a compilation issue in 'drivers/video'. Namely 'fbgen.o' is used by some other objects ('pm2fb.o', 'pm3fb.o', 'clgenfb.o', 'tridentfb.o', 'tgafb.o', 'stifb.o'). Now if at least one of these "users" is configured as built-in, implying that fbgen.o will be compiled as an integral part of a kernel, and some other(s) as modules then you will see from 'depmod' complaints about unresolved symbols for functions provided by fbgen.
A fix is obvious. Add missing EXPORT_SYMBOL(...) to 'fbgen.c' and 'fbgen.o' to a list of export-objs in drivers/video/Makefile. Here is a patch (for 2.4.19-pre8 but this did not really change for quite a while).
