Configuration was done with

../trunk/configure --with-isl=$HOME --prefix=$HOME
--enable-languages=c,fortran,c++,lto && make -j6 && make install

The version of ISL was the one that is advertised on the gcc web site, 0.12.2.

Looks like it doesn't use/prefer the configured ISL headers.  Unfortunately you
left out the actual compiler command lines.

I think we now need very very recent ISL (use of 0.11 is also broken this way
but still accepted by configure and documented as working).

Installing a more recent (0.1.3) libisl makes configure fail with

checking for version 0.11 of ISL... no                                          
checking for version 0.12 of ISL... no
configure: error: Unable to find a usable ISL.  See config.log for details.

Is there a way that I can revert bootstrap capability, short of reverting
revision 212455?

--- Comment #6 from Manfred Schwarb <manfred99 at gmx dot ch> ---
There is ./configure --disable-isl-version-check,
but I doubt that it will help. The thing is, isl-0.13 needs
cloog-0.18.2 (or rather, cloog-0.18.1 needs isl-0.12.2 and does
not build with isl-0.13), which is not yet released.

Now I heard that the goal is to do without cloog, but I guess
the configure machinery (and probably, the rest of the graphite code)
is not yet up to it.

There really needs an immediate solution to this issue,
I think ATM there is no way to build graphite without resorting to
non-released libraries.

I suggest to revert all these isl-0.13 dependencies until cloog-0.18.2
is released, or there is shown some way to build graphite without cloog.

Roman, how is one supposed to build GCC with graphite support?

For the record, I have done a clean bootstrap of r212523 on
x86_64-apple-darwin13 with cloog-0.18.1 and isl-0.12.2.

The graphite-isl-ast-to-gimple.c code reads

#ifdef HAVE_cloog
#include <isl/set.h>
#include <isl/map.h>
#include <isl/union_map.h>
#include <isl/ast_build.h>
#if defined(__cplusplus)
extern "C" {
#endif
#include <isl/val_gmp.h>
#if defined(__cplusplus)
}
#endif
#endif


and val_gmp.h only exists in isl-0.13.
So maybe things work when disabling/not using cloog?
Will have to check tomorrow.

I have val_gmp.h for isl-0.12.1 and isl-0.12.2:

[Book15] f90/bug% find /opt/libs -name val_gmp.h
/opt/libs/cloog-0.18.1/isl/include/isl/val_gmp.h
/opt/libs/isl-0.12.1/include/isl/val_gmp.h
/opt/libs/isl-0.12.2/include/isl/val_gmp.h

and they are all the same.

Dominique, you are right.
The issue is not with isl-0.12 and isl-0.13.

It is isl-0.11 that is missing these include files. So with the
above mentioned check-in, building GCC using isl-0.11 does no longer work.

I just could build trunk successfully now, using isl-0.12.2.

One should rip isl-0.11 support out of configure etc. therefore.


OK, I see what could have happened to Thomas: GMP support in isl
is optional. If you build isl without gmp headers being present,
then probably you wont get the needed headers to compile GCC.

So it seems isl-0.12.2 with GMP support is needed to build graphite.

GMP support only became optional with the unreleased isl-0.14. graphite should
build correctly with isl-0.12.2 and cloog-0.18.2. We should remove remove other
versions from the configure check.

Roman, is currently working on adapting configure.
