Myself using Interix and "Mook" using Wine have both tried to
cross-compile Mozilla using MSVC as a cross compiler. Generally I would
like to think that NSS has been the easiest part to cross compile, but
here are the issues we ran into:
1. Because we're not using GCC or MSYS, rules.mk tries to run cygpath
-w `pwd` which fails because we have no cygpath.
2. AR does not get set correctly because AR_FLAGS contains $@
3. LINK fails to run because the environment contains LINK=link which
it sees as a request to link link.obj
4. RC fails to run because some of the NSPR includes can't determine
the target processor (_X86_ does not get defined)
5. Because he was using VC8 Mook also had some issues with manifests.
I would be happy to write patches for these if you would advise me as to
whether my ideas are useful.
1. I wrapped the code in a test for NATIVE_CC; Mook used
CROSS_COMPILE but I think that relies on you exporting it from the
shell.
2. AR='$(subst $@,$$@,$(AR) $(AR_FLAGS))' (Mook used a similar construct)
3. Mook prefixed LINK= $(LINK) to temporarily clear the variable; my
suggestion is to rename $(LINK) to $(LD) in the makefile
4. Currently we work around this by preventing rc from including
seccommon.h but I'd appreciate ideas for how to persuade NSS that
i686 is _X86_
5. I don't know about this, but I could ask Mook to chime in if you
thought it would be useful.
