BUG: g95-0.90 Installation of py-scipy fails because g95 won't compile

[jmnc@…]

When trying to to install py-scipy on a fresh install of MacOS X 10.5, port fails when working on g95 with the following message:

I was able to compile g95 on PPC/Leopard but still have problems on Intel.

[carnevale@…]

Even if I have a PPC/Leopard too, I am not able to compile g95. I tried to install gcc-4.0.4 (please refer to: http://www.nabble.com/g95-t4786163.html) or gcc-4.1.2 to fix it, but they don't compile on my box.

[takeshi@…]

On my Mac mini/PPC, I was able to install g95 with a modified Portfile and a few patches (attachment at 2007-11-18 02:16:52). I have not tested thoroughly but at least it compiles "Hello world". It does not work on Intel. So the modified portfile is not meant for an updated version.

[takeshi@…]

I was able to build on Intel Mac as well. However, I still get annoying assembler error. An executable ("Hello, world!") seems to work. I updated Portfile and patches.

additional patch 2/2

[takeshi@…]

Now g95 compiles sources without complaining :-)

[takeshi@…]

gmp and mpfr packages are not necessary for g95. I did not have to add these to Portfile depends_lib.

I tried to update Portfile.patch but I was unable to attach the file.

[deleted]

Can any admin please clarify this to a g95 bug (lang/g95) ?

[takeshi@…]

Could anyone who can commit take a look at this? I replaced Portfile.patch to the one w/o gmp and mpfr.

[ryandesign@…]

I committed your patch in r32219, except that I removed the lines you had commented out, I fixed the whitespace to match the rest of the portfile (no tabs), and I fixed the names of the patchfiles to match port lint recommendations.

I tested it on Tiger and it still built ok. Don't have Leopard to test with, but I trust you did sufficient testing there.
