| Subject: | option to ignore Perl's ccflags/ldflags, or filter them properly |
Perl's compiler and linker flags aren't all that innocent. They will
insert directives which may affect how object code is generated, and
conditionally enable/disable other code. For using/checking external
dependencies, it might be nice to disable some of these flags; e.g.
(from Debian)
# /usr/bin/cc -D_REENTRANT -D_GNU_SOURCE -DDEBIAN -fno-strict-aliasing -
pipe -fstack-protector -I/usr/local/include -D_LARGEFILE_SOURCE -
D_FILE_OFFSET_BITS=64 -fstack-protector -L/usr/local/lib -ldl -lm -
lpthread -lc -lcrypt assertlibZZpeAaDI.c -o assertlibflwckxnH
Or an even more offending version (from NetBSD):
# /usr/bin/cc -O2 -pthread -I/usr/include -fno-strict-aliasing -pipe -
fstack-protector -Wl,-R/usr/pkg/lib -Wl,-rpath,/usr/pkg/lib -fstack-
protector -lm -lcrypt -lpthread assertliby6mTaz3d.c -o assertlibp3vtu5J3
^ This one uses -rpath
But most of the times, the flags are what 'you'd want anyway', so..
Better yet, figure out a way to maintain the search paths (since that's
all we really care about), but strip out the other cruft, though that
might be outside the scope of this module
