Hi, Until today I had never tried autoreconf. I have always used a simple shell script like: #!/bin/sh rm -f config.cache rm -f acconfig.h echo "- aclocal..." aclocal -I m4 echo "- autoconf..." autoconf echo "- autoheader..." autoheader echo "- automake..." #automake -a -v automake -a echo "- ready!" exit The script runs just fine, but autoreconf complained about my use of AC_CREATE_STDINT_H, insisting that I use m4_pattern_allow, which I did, and the problem vanished. But, would anyone explain what happened and why? Does it perhaps have anything to do with the fact that this macro is the only one I am using named AC_*, rather than say ACX_*? TIA, Robert _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
