There is a problem when cross compiling linux-2.4.20 for a ppc-8xx system on a RedHat-7.3 x86 host using gcc-2.95.4. It complained that stdarg.h couldn't be found when sched.c is compiled. I compared the Makefile of 2.4.20 with the one of linuxppc_2_4_devel and found that it was caused by the different definition of kbuild_2_4_nostdinc.
2.4.20 Makefile defines kbuild_2_4_nostdinc as the following: kbuild_2_4_nostdinc := -nostdinc -iwithprefix include It doesn't work. linuxppc_2_4_devel Makefile defines kbuild_2_4_nostdinc as the following: kbuild_2_4_nostdinc := -nostdinc $(shell $(CC) -print-search-dirs | sed -ne 's/install: \(.*\)/-I \1include/gp') It works for me.
Please CC replies to me. Thanks.
