isl: isl.pc differs and cannot be merged

[petrsnd@…]

I want to install gcc46 on Mac OS X Server 10.6.8 Snow Leopard.

I issued the command:

port install gcc46 +universal

When installing the isl dependency it just fails. It complains about a directory that already exists. If I try to install isl separately, I receive the same result, even with the force flag:

port -f install isl +universal

I tried to clean isl and then rebuild it, but it also failed:

port clean isl && port install gcc46 +universal

Here is the failure output during the staging of isl into destroot:

Could you please attach the two aforementioned isl.pc files so that we can see how they differ?

[pixilla (Bradley Giesbrecht)]

Possibly related: gcc46 depends on cloog which has a file conflict with isl. #34477

[petrsnd@…]

From destroot-x86_64/opt/local/lib/pkgconfig/

[petrsnd@…]

From isl-0.07-x86_64/

[petrsnd@…]

They are the same.

Did r93464 fix the problem for you?

[ryandesign (Ryan Carsten Schmidt)]

petrsnd, you attached the wrong files. I wanted the isl.pc file from the destroot-x86_64 directory (which you attached) and the destroot-i386 directory.

[petrsnd@…]

destroot-i386/

[petrsnd@…]

# diff ./destroot-i386/opt/local/lib/pkgconfig/isl.pc ./destroot-x86_64/opt/local/lib/pkgconfig/isl.pc 17c17 < Libs: -L${libdir} -L/opt/local/lib -arch i386 -lisl -lgmp ---

That fix is incorrect. Your configure change does not match your m4 change. See #34623 for a better solution.

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

The isl configure script automatically calls autoreconf if it can find it.
Otherwise, it just runs normally.
The original fix was to make the same change in two places (r93464 and r92991).

r93580 is a better fix.

This is working now. Thank you.
