I'm trying to write a simple program to be loaded from disk by a bootloader. This test program is as follows: #include <stdio.h> int main() { printf("Test\n"); return 0; } I compile it with gcc -c mytest.c then try to link it as a pure binary file (so my bootloader can load it) as follows ld mytest.o -o mytest.bin -oformat binary -Ttext 0x100000 -lc but this produces the error: warning: cannot find entry symbol start; defaulting to 00100000 followed by many errors such as: d:/djgpp/bin/../lib/libc.a(doprnt.o)(.text+0xafd):doprnt.c: undefined reference to '___umoddi3' d:/djgpp/bin/../lib/libc.a(doprnt.o)(.text+0xb3c):doprnt.c: undefined reference to '___udivdi3' does anyone now where I'm going wrong Thanks WM
