Forgive my ignorance here because I still write my makefiles by hand.
If I wanted to delete an option used by the project, is it as simple
as removing the option from the switch statement around line 155:
AC_DEFUN([SQUID_CC_GUESS_OPTIONS], [
AC_REQUIRE([SQUID_CC_GUESS_VARIANT])
AC_MSG_CHECKING([for compiler variant])
case "$squid_cv_compiler" in
gcc)
squid_cv_cc_option_werror="-Werror"
squid_cv_cxx_option_werror="-Werror"
squid_cv_cc_option_wall="-Wall"
squid_cv_cc_option_optimize="-O3"
squid_cv_cc_arg_pipe="-pipe"
;;
sunstudio)
...
So I would delete squid_cv_cc_option_werror="-Werror" and
squid_cv_cxx_option_werror="-Werror" to remove the option (from all
compilers under the switch).
How about adding options? Can I define a new option on the fly? For example:
squid_cv_cc_option_nx_stack="-Wl,z,noexecstack"
squid_cv_cc_option_nx_heap="-Wl,z,noexecheap"
No-exec heaps are only available on PaX enabled kernels (such as
Gentoo), so can I expect the autotools to do the right thing and only
add it if available?
Thanks in advance.
