Many programs that are not included in the distribution and which I tried to compile / build a RPM, failed during %configure with ltconfig: unrecognized option `--add-tag=CXX' At the beginning there is the warning: libtoolize: `/usr/share/aclocal/libtool.m4' is serial 40, less than 45 in `aclocal.m4' But when I use the old './configure', it worked. What's wrong? Incompatible libtool or automake?
