Hi there,
GCC developers that also track the Parma Polyhedra Library (PPL, http://www.cs.unipr.it/ppl/) are in a situation whereby, while the GCC compiler is requiring Autoconf version 2.59 (precisely that one), the PPL requires a version >= 2.61. This is annoying, because they are forced to use at least two different versions of Autoconf.
Basile Starynkevitch (in CC) suggested we put a generated configure script on the CVS repository. Thus we now have configure.repo in the repository, the idea being that a simple
mv configure.repo configure
could be used as an alternative to autoconf. However, the problem remains how to perform the update of all the other generated configuration files. In other words, we would need something that acts like autoreconf except for the fact that it would not attempt to build configure from configure.ac. Probably a small shell script invoking libtool, aclocal, automake in the right order and recursing to subdirectories is what is needed, but we are not sure. What is the right solution? All the best,
Roberto
