README for uC-libc on the m68k[nommu] architecture James Graves <jgraves@deltamobile.com> For now (2001/1/9) support for the m68k should be considered "alpha" quality at best. It mostly works OK for some of the stuff I'm working on, but you can't fully compile other things (like the user applications for uClinux). Needs lots more testing. Only developed/tested with m68k-pic-coff-gcc 2.7.2.3-pic-060999, from Lineo. Configuration: Read and edit the Config file, carefully. TARGET_ARCH=m68k CROSS = m68k-pic-coff- CC = $(CROSS)gcc STRIPTOOL = $(CROSS)strip KERNEL_SOURCE=/opt/uClinux/linux HAS_MMU = false HAS_FLOATS = false MALLOC = malloc-simple INSTALL_DIR = /opt/uClinux/m68k-pic-coff The regular malloc library is broken, dunno why. Use simple-malloc. Installation: Theoretically, you should be able to install right over the existing uC-libc 0.9.1 files in /opt/uClinux/m68k-pic-coff/include, but I recommend cleaning out all the include files there. The only file in there that's not from the old uC-libc is assert.h, but I don't know why that would be the valid copy. run: make install Problems: I _may_ be able to help if you run into problems. Create a really, really short program that demonstrates the problem, and contact me. TODO: Fix vfork(). Does crt0.o still need to be a separate file? Can't I just stick it in libc.a and be done with it? Is that specified in the GCC link options?
