I am attempting to compile MIT/GNU Scheme on cygwin. The build proceeds fine through the main executable, but fails when linking a dynamically openable module.
The main executable is created with this command: > gcc -o scheme.exe cmpauxmd.o <other.o's> <libs> cmpauxmd.o is created by: > ./makegen/m4.sh cmpauxmd.m4 > cmpauxmd.s > as -o cmpauxmd.o cmpauxmd.s The <other.o's> are all compiled from .c files. The first module fails to link as follows: > gcc -shared -o prbfish.dll prbfish.o <module_libs> --> Lots of "prbfish.o:prbfish.c: undefined reference to X" where the X's are symbols defined in both cmpauxmd.o and <other.o's> So I tried to create a helper lib just to provide symbols for prbfish.dll: > gcc -shared -o libscheme.dll cmpauxmd.o <other.o's> <libs> --> Cannot export asm_sc_apply_generic: symbol not found --> several more "Cannot export"s All the "Cannot export" symbols are defined in cmpauxmd.o In fact, I get the same error when I try > gcc -shared -o prbfish.dll prbfish.o cmpauxmd.o <other.o's> <module_libs> > <libs> --> Cannot export asm_sc_apply_generic: symbol not found ... Is my approach of building a helper lib the correct one? If so, how do I resolve the "Cannot export" errors? OR ... Is there another (better) way to inform ld of the symbols in scheme.exe in order to succesfully link the module .dll's? regards, NT -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
