Hi,
Over the weekend I had a go at building GCCSDK on a fresh install of
Lubuntu 17.04, using the default GCC + makeinfo/texinfo packages (GCC
6.3.0 & makeinfo 6.3).
GCC 6.3 didn't like the version of PPL we're using (it complained about
some classes which contained a "[]" flexible array as the last member). So
I've fixed that by updating to the latest version of PPL (which allows us
to drop some now redundant patches, but also introduces a couple of new
patches because GCC and cloog had bogus PPL version checks). AIUI more
recent versions of GCC have dropped PPL in favour of a different library
("isl"), so I'll leave it to you to decide whether updating the PPL
version is worth it or not (it's possible it's affected code
generation/optimisation, since GCC built with new PPL seems to produce
different binaries compared to other builds of GCC with old PPL)
Meanwhile, makeinfo barfed at a couple of pieces of dodgy syntax in the
GCC docs. Checking against the latest GCC sources shows that they've
changed that part of the docs to use an alternative syntax, which looks
like it should be supported under all the makeinfo versions we support:
https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/doc/gcc.texi?r1=203064&r2=203065&
After patching the above issues I was able to build functioning versions
of the cross-compiler and native compiler. Patches attached.
Cheers,
- Jeffrey
