The installation instructions for GCC 4.7.1 aren't on the website. Please read my mail again. I said the http://gcc.gnu.org/wiki/Graphite_Build instructions are probably out of date and not authoritative. The instructions at http://gcc.gnu.org/install apply to SVN trunk, not to the 4.7.1 release you're using. You were very clear that you want to use that release, so you should be looking at gcc-4.7.1/INSTALL/index.html in the release sources. You clearly aren't doing that, because you're not using the versions suggested there. > I've tried to build with following versions of CLooG: > > cloog-0.17.0.tar.gz (from CLooG.org) The 4.7.1 installation instructions say to use 0.15 or 0.16 > cloog-0.16.2.tar.gz (from gnu.org) That worked fine for me. > cloog-parma-0.16.1.tar.gz (from CLooG.org) > cloog-polylib-0.16.1.tar.gz (from CLooG.org) > development snapshot via git (from git://repo.or.cz/cloog.git ) > > And with following versions of other libs: > > gmp-5.0.5.tar.gz > mpc-0.9.tar.gz > mpfr-3.1.1.tar.gz > polylib-5.22.5.tar.gz > ppl-1.0.tar.gz The 4.7.1 instructions say to use ppl 0.11 Instead of complaining that releases should be marked experimental if the given instructions don't work, maybe you should actually follow the given instructions? > For each mentioned library, `make check` passes good (including CLooG). > > However, when it comes to graphite build, I always experience one of two > outcomes: > > > 1. configure fails with following message: > > checking for version 0.11 (revision 0 or later) of PPL... no > configure: error: Unable to find a usable PPL. See config.log for details. Did you use --enable-cloog-backend=isl as documented in gcc-4.7.1/INSTALL/prerequisites.html? > 2. if I provide --disable-ppl-version-check to graphite's configure, Don't do that. Here are the steps that worked for me (with gmp-devel 4.3.1 installed from RPM, it should also work if installed manually, mpfr and mpc sources placed in the GCC source tree) wget ftp://gcc.gnu.org/pub/gcc/infrastructure/ppl-0.11.tar.gz tar xzf ppl-0.11.tar.gz cd ppl-0.11 ./configure --prefix=/blah/ppl --enable-interfaces=c,cxx make make install cd .. wget ftp://gcc.gnu.org/pub/gcc/infrastructure/cloog-0.16.2.tar.gz tar xzf cloog-0.16.2.tar.gz cd cloog-0.16 ./configure --prefix=/blah/cloog --with-ppl=/blah/ppl make make install cd .. mkdir objdir cd objdir export LD_LIBRARY_PATH=/blah/cloog/lib:/blah/cloog/ppl/lib ../gcc-4.7.1/configure --with-ppl=/blah/ppl --with-cloog=/blah/cloog --enable-cloog-backend=isl <other options> make It worked perfectly for me. If you want further help then you'll need to be clearer about what instructions you are using and exactly what steps you followed. Obviously you're doing something wrong, because following the instructions works for me. Please follow the instructions in gcc-4.7.1/INSTALL including using --enable-cloog-backend=isl if appropriate and if that doesn't work please be explicit about exactly what configure commands you used.
