I'm actually one step ahead: deleted everything, rearranged path, configure,
make all, make install, got lib, created hw9012.ld, linked with libnosys.a.
m68k-coff-gcc -nostdlib test.c -Thw9012.ld -Wl,-Map=test.map
test.c: In function `sbrk':
test.c:4: warning: return makes pointer from integer without a cast
C:\tmp\ccXHJywX.o(.text+0x3c):test.c: undefined reference to `__main'
\gcc-m68k\m68k-coff\lib/libc.a(exit.o): In function `exit':
reference to `_exit'
I can deal with those symbols when I modify libgloss. This leads to the
next question: how do I add our OS to libgloss? For the lib I could just hack
away in the libnosys directory, but as I probably need my own crt-hwdos.S
anyway I could use a seperate directory. Or better place the code into
libgloss/m68k. Where do I add my filenames?
It's a complete OS with trap entries but obviously not already implemented
