Hi all,
I'm using autoconf version 2.64 (Ubuntu 9.10) and in my configure script,
I've got:
AC_LANG([C++])
AC_ADD_CXXFLAGS([-std=gnu++0x])
AC_CHECK_HEADER(cstdint)
where AC_ADD_CXXFLAGS checks to see if the compiler accepts the given
CXXFLAGS and adds it to CXXFLAGS if is acceptable.
However, with the above, I'm getting:
checking if g++ accepts -std=gnu++0x... yes
checking cstdint usability... yes
checking cstdint presence... no
configure: WARNING: cstdint: accepted by the compiler, rejected by the preprocessor!
configure: WARNING: cstdint: proceeding with the compiler's result
checking for cstdint... yes
and I don't get a HAVE_CSTDINT in the config.h file.
Any clues on whats going on here?
Cheers,
Erik
