I get the same error on an Intel Mac running Leopard 10.5.8 with Xcode 3.1.3 when trying to compile with MacPorts compiler gcc 4.3.4.

[jochen@…]

As I said before, this is untested and unsupported:

Done in r57589 (untested and unsupported)

Please provide a patch to make it work, I will happily apply it.

[jwhowse4]

I am trying to compile with gcc43 not gcc44 and I am still getting this failure.

[jochen@…]

So what's the relevant part of config.log?

[jwhowse4]

Here what happens. When I run an install I get the following error.

port -v install gsl +gcc43 +doc
Error: gsl: Variant gcc43 conflicts with gcc43
Error: Unable to open port: Error evaluating variants

This is just because the Portfile says that gcc43 conflicts with gcc43. I believe this should read gcc43 conflicts with gcc44. Making this change to the Portfile and trying the install again gives the following error.

port -v install gsl +gcc43 +doc

This looks to me like the same error the gentlemen above obtained when trying to compile using gcc44. I will also attach my config.log file.

[jochen@…]

So the problem is that MacPorts since version 1.8 apparently automagically adds

-arch x86_64

to the cflags and the MacPorts GCCs don't understand that...

I'll see how to disable it, but any feedback is welcome.

[jochen@…]

Well, this might take a while, as I can not compile gcc43 nor gcc44 on Snow Leopard (which is all I have), see Ticket #20816. If you can figure out how to remove the "-arch ..." statements from configure.cflags and friends, I'll implement it.

Attached is a Portfile that worked for me. I am using an Intel Mac running Leopard 10.5.8 and compiling with the Macports GCC 4.3.4 compiler.
