Hi,

The graphite branch has been tuplified and the port to PPL passes the graphite testsuite. For building the graphite branch right now, here are the steps you'll have to go through:

You have to get a copy of the release 0.9 of PPL from: http://www.cs.unipr.it/ppl/Download/

I see this is documented as needing (a) C++, (b) GCC 4.0.3 or later, (c) GMP compiled with the C++ interface enabled. I believe we previously reached a conclusion that if GCC is made to require C++ it would work with any version of GCC 3.4 or later (and did not discuss the question of the GMP C++ interface). Recall that right now the documented requirement is that a cross-compiler (so all non-Ada front ends) can be built with GCC 2.95 or later; Ada requires 3.4 or later; and any ISO C compiler should work for bootstrapping a native compiler.

If Graphite can be disabled then the bootstrapping issue goes away as you can in a first step build current GCC with C++ enabled and do a second stage with Graphite enabled.

At this point I think the policy questions regarding the build requirements for graphite, even as an optional feature, need to be raised on their own in a thread on the gcc list rather than buried in the patch discussion.

I agree. At least this is the place for requesting Host testing on non-Linux hosts. Note that Fedora has packages for the PPL, likewise has Debian. I am in the progress of building ones for SUSE.

Richard.
