Description Bernhard Ege 2000-08-03 08:54:45 EDT
Having enabled AGP support (general and AMD Irongate support) the
compilation halts in drivers/char with this message:

rm -f char.a
ar  rcs char.a pty.o misc.o console.o selection.o serial.o keyboard.o
sysrq.o tty_io.o n_tty.o tty_ioctl.o mem.o random.o raw.o vt.o vc_screen.o
consolemap.o consolemap_deftbl.o pc_keyb.o defkeymap.o rtc.o agp/agpgart.o
ar: agp/agpgart.o: No such file or directory
make[3]: *** [char.a] Error 1

Files present in drivers/char/agp are:

Makefile  agp.o          agpgart.h     agpgart_be.o  agpgart_fe.o
agp.h     agp_backend.h  agpgart_be.c  agpgart_fe.c

Makefile has a target called agpgart.o, but O_TARGET is set to agp.o. Which
os these two targets is the correct one?

I chose to change O_TARGET to agpgart.o and resumed compilation. This time
it continued all the way to the end, when it failed with this error:

make: *** [vmlinux] Error 1

I have search the source with "rgrep -ril agp_initialize *" (started in
/usr/src/linux) and it did not find that symbol. agp_setup is not even used
by init/main.c and agp_initialize exists as agp_frontend_initialize and
agp_backend_initialize.

Yes....I had the identical problem with 2.2.16-12 from rawhide....the only
way you can compile is as a module!
