Re: problem building a dll that uses other dll's

[jeffdbREMOVETHIS at netzone dot com (Mikey)]

The dll is not the stub library, the stub library
for foo.dll is libfoo.a

to use ld.exe directly, you would need to do

ld --subsystem [ windows/console ] --dll -e _dll_entry@12 -o prog.exe prog.o -L/search/dir -lfoo

the -l automatically adds the lib prefix, and the .a suffix. to the stub library name

-L is used to add a search path for ld.

The order of files on the link line IS important, since ld is
a one pass linker, references must be resolved by
object files farther allong in the link line.

BTW all of this stuff is in the ld man page, and also
in gcc.info, you might try reading them.
