Does ppl (and cloog) build automatically if you use

options in the gcc configure command? I know gmp and mpfr build automatically if you unzip them in the gcc source directory (or provide soft links to their location).

Hi Bill, even though this is a question for the GCC people, I have checked GCC's configuration machinery, and it seems that the PPL and CLooG are indeed treated like GMP and MPFR. For instance, in GCC's root directory Makefile.in you can find: @if ppl maybe-configure-ppl: configure-ppl configure-ppl: @r=`${PWD_COMMAND}`; export r; \ s=`cd $(srcdir); ${PWD_COMMAND}`; export s; \ test ! -f $(HOST_SUBDIR)/ppl/Makefile || exit 0; \ $(SHELL) $(srcdir)/mkinstalldirs $(HOST_SUBDIR)/ppl ; \ $(HOST_EXPORTS) \ echo Configuring in $(HOST_SUBDIR)/ppl; \ cd "$(HOST_SUBDIR)/ppl" || exit 1; \ case $(srcdir) in \ /* | [A-Za-z]:[\\/]*) topdir=$(srcdir) ;; \ *) topdir=`echo $(HOST_SUBDIR)/ppl/ | \ sed -e 's,\./,,g' -e 's,[^/]*/,../,g' `$(srcdir) ;; \ esac; \ srcdiroption="--srcdir=$${topdir}/ppl"; \ libsrcdir="$$s/ppl"; \ $(SHELL) $${libsrcdir}/configure \ $(HOST_CONFIGARGS) --build=${build_alias} --host=none-${host_vendor}-${host_os} \ --target=none-${host_vendor}-${host_os} $${srcdiroption} --disable-shared --with-libgmp-prefix=$$r/$(HOST_SUBDIR)/gmp/ --with-libgmpxx-prefix=$$r/$(HOST_SUBDIR)/gmp/ \ || exit 1 @endif ppl I hope this helps.
