Hi All,
I'm interested in trying to figure out how to "cleanly" set options
for CFLAGS (and CXXFLAGS) and LDFLAGS. I also want it to intelligently
apply to programs and shared objects. The problem I am having is
programs need:
CFLAGS += -fPIE
LDFLAGS += -pie
while shared objects need:
CFLAGS += -fPIC
LDFLAGS += -shared
So I can't run configure to set up a project properly:
$ configure CFLAGS="-Wall -Wextra -Wconversion -fPIE -pie
-Wno-unused-parameter -Wformat=2 -Wformat-security
-fstack-protector-all -Wstrict-overflow
-Wl,-z,noexecstack -Wl,-z,relro -Wl,-z,now"
I see others have also felt the same discomfort
(http://lists.fedoraproject.org/pipermail/devel-announce/2011-August/000821.html):
"All of this is only an issue because most build systems don't
let you say different CFLAGS or LDFLAGS for shared libraries
and executables. Sigh."
Any ideas?
Jeff
