[PPL-devel] [Bug Report] GMP and PPL mismatches

[Chia-Hsun Cheng]

Dear Roberto Bagnara,

I followed the provided link and downloaded ppl-1.1pre6 version. The
compilation was fine and all tests
in "make check" passed. The build-up of gcc was successful as well.
Thanks for the fast response and kind help!


Dear Marco Bodrato,

Thanks for the notification that solves my confusion!

Best Regards,
