hi, i've got a software (log4cpp v0.3.4b) that i would update the build system. i've done an autoreconf -f -i and autoconf failed with these errors : configure.in:59: error: possibly undefined macro: AC_C_INT64_T If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. configure.in:60: error: possibly undefined macro: AC_CXX_HAVE_SSTREAM configure.in:61: error: possibly undefined macro: AC_FUNC_SNPRINTF configure.in:94: error: possibly undefined macro: AC_CREATE_GENERIC_CONFIG configure.in:130: error: possibly undefined macro: AC_CREATE_PREFIX_CONFIG_H all the macros exists. they are in a m4 subdir. i'm not familiar with autotools, i juste want an updated configure. any help, advice or comments would be appreciated. cheers, Fathi _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
