I am using Msys to build a home brew kernel that I wrote under Linux. Linux used ELF for its binary format and Msys uses PE. I have the source setup to allow it to be booted by Grub using the Multiboot spec. At the end of the build, I get some undefined symbols:
init.o:init.S:(.text+0x14): undefined reference to `edata'
main.o:main.c:(.text+0x121): undefined reference to `_alloca'
main.o:main.c:(.text+0x126): undefined reference to `__main'
../../lib\libkern.a(mem.o):mem.c:(.text+0x242): undefined reference to `_end'
../../lib\libkern.a(mem.o):mem.c:(.text+0x323): undefined reference to `_end'
These appear to be ELF oriented symbols. If anyone can advise me on how these should be dealt with in the PE world, e.g. if there are equivalents, it would help me out a lot!
