posix64 build fails #235

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Build fails when building the v10 branch on a posix64 Linux system.  Reported 
by piranna on the maillist on 2012/04/21::

1º
src/platform/posix64/build/vm/strobj.c: In function 'string_format':
src/platform/posix64/build/vm/strobj.c:339:13: error: variable
'smallfmtcstr' set but not used [-Werror=unused-but-set-variable]

but the fact is that inspecting the file, the var is being used after
that point! :-/ Any idea?

2º
After removing the -Wall flag at SConscript, i get the next one:

gcc -o src/platform/posix64/build/main -Wl,-map
src/platform/posix64/build/main.map src/platform/posix64/build/main.o
src/platform/posix64/build/plat.o
src/platform/posix64/build/vm/libpmvm.a
src/platform/posix64/build/pm_generated_objs.o
/usr/bin/ld: unrecognised emulation mode: ap

It seems the flag is wrong, according to documentation should be -Map
('M' instead of 'm')

3º
Finally, after fixing the previous one i get the next errors on the
linker... and this i can't be able to fix them :-/

To number one:
'smallfmtcstr' is set but never used if the symbol HAVE_SNPRINTF_FORMAT is set. 
The attached patch adds more guards to strobj.c.
