Bill, Geoff, >I think that in addition to --nostartfiles, you also want --nodefaultlibs. >LD=m68k-coff-ld >LDFLAGS=-nodefaultlibs -nostdlib >and >CC=m68k-coff-gcc >CCFLAGS=-nostartfiles Thanks for the suggestions, I tried it but at 0x0 there are still things that i do not want. At 0x0 should be 0x0B40000, at 0x4 should be the adress of main (=0x400) and at 0x400 should be main followed by the WritePortB routine. Let me include my commandline and some extra information: I hope that you can see where i go wrong. (I guess the collect2 does something evil :) [(08:07:36) jan@pco449 ~]$ cd ledtest/ledtest [(08:07:46) jan@pco449 ~/ledtest/ledtest]$ m68k-coff-gcc -v -m68040 -g -O2 -nostartfiles -fverbose-asm -fpack-struct -Wall -Wl,-Tauc.ld -Wl,-nodefaultlibs -Wl,-nostdlib -save-temps -o boot.ieee main.c Reading specs from /usr/local/lib/gcc-lib/m68k-coff/2.95.3/specs gcc version 2.95.3 20010315 (release) /usr/local/lib/gcc-lib/m68k-coff/2.95.3/cpp0 -lang-c -v -D__GNUC__=2 -D__GNUC_MINOR__=95 -Dmc68000 -D__embedded__ -D__mc68000__ -D__embedded__ -D__mc68000 -Asystem(embedded) -Amachine(mc68000) -D__OPTIMIZE__ -g -Wall -D__HAVE_68881__ -Dmc68040 -D__mc68040__ -D__mc68040 main.c main.i GNU CPP version 2.95.3 20010315 (release) (68k, Motorola syntax) #include "..." search starts here: #include <...> search starts here: /usr/local/lib/gcc-lib/m68k-coff/2.95.3/include /usr/local/lib/gcc-lib/m68k-coff/2.95.3/../../../../m68k-coff/include End of search list.
