Autoconf-2.53
I've got a macro which test available C flags
and cache the result. It used to work well with
ac-2.13. Since I upgraded to 2.53, I noticed that
my macro always return "yes" whatever flag I try
(e.g. -Wallall will work with gcc...).
The problem comes from AC_TRY_COMPILE which
seems to not compile anything...
The command I'm using looks like:
AC_TRY_COMPILE([],[],
[eval "${ac_try_cflags_var}=yes"],
[eval "${ac_try_cflags_var}=no"])
where ac_try_cflags_var is the name of the
variable to cache.
I didn't try with other 2.5x variants.
Did somebody else face this problem ?
Am I missing some change in how to use
this macro ?
Thx !
PS: any release plan for ac-2.54 ? :o)
