[petrrr]

The updated port fails to configure on an Mac OS X 10.5.8 system.

The respective main.log and config.log attached.

Thanks. In the future, please Cc relevant port maintainers.

Fixes to this problem were discussed here: ​http://www.open-mpi.org/community/lists/devel/2011/01/8923.php

Either add -xassembler for Apple gcc-4.0, or use Apple gcc-4.2:

The assembler code...

$ cat conftest.s
.text
# _gsym_test_func
.globl _gsym_test_func
_gsym_test_func:
# _gsym_test_func

Failure during configuration...

$ /usr/bin/gcc-4.0 -std=gnu99  -DNDEBUG -pipe -O2 -arch ppc -finline-functions -fno-strict-aliasing -c conftest.s
conftest.s:2:3: error: invalid preprocessing directive #_gsym_test_func
conftest.s:5:3: error: invalid preprocessing directive #_gsym_test_func

gcc-4.0 with -xassembler produces no output (the desired result)...

$ /usr/bin/gcc-4.0 -std=gnu99  -DNDEBUG -pipe -O2 -arch ppc -finline-functions -fno-strict-aliasing -xassembler -c conftest.s

gcc-4.2 produces no output (the desired result)...

$ /usr/bin/gcc-4.2 -std=gnu99  -DNDEBUG -pipe -O2 -arch ppc -finline-functions -fno-strict-aliasing -c conftest.s

The attached patch works for me

Blacklisting gcc-4.0 is probably easiest.

compiler.blacklist  gcc-4.0

[petrrr]

Blacklisting worked for me. Should I provide a diff or will the maintainer commit this directly?

[petrrr]

This problem persists in the updated version 1.7.2. So what about blacklisting gcc-4.0 ?

Maintainer timeout, done in r108127.
