py-scipy fails to build due to broken g77 dependency

[Kai.Puolamaki@…]

py-scipy depends on, among others, g77 port.

However, g77 port fails to build and won't be fixed, see bug 3066, ​http://bugzilla.opendarwin.org/show_bug.cgi?id=3066

Quoting from 3066:

Resolution: WONTFIX

---

the g77 port is basically obsolete and should be removed. Try using the gcc34 or gcc4 ports instead as they both include fortran compilers.

fixed portfile

[Kai.Puolamaki@…]

I replaced the py-scipy portfile. However, it didn't work for me. :( The build failed due to missing g2c library.

Thanks. The new Portfile (attachment 2524) does not work. :(

I got the above error when g++ wasn't able to find the numeric include libraries. Maybe those need to be passed as CFLAGS.

[zpincus@…]

I finally got SciPy to compile on Tiger (with XCode 2.1 tools.)

While I'm not qualified to write this up as a proper portfile, here's what I now know: (1) Using a recent CVS grab of SciPy is better because the gnufcompiler.py file doesn't need much patching at all. But this may not be necessary.

(2) What is ABSOLUTELY NECESSARY for getting SciPy to work is to compile it (and everything that links with it, such as FFTW) with gcc3.3 or gcc3.4. This is because g77-generated code can only be linked properly with gcc3.x code; if you want to link with gcc4-generated code, you have to compile the fortran with gfortran. Which currently is unsupported (and not working) for SciPy.

So, I think that: (a) The g77 port should be updated to gcc3.4, since there's no interest in fixing g77 for gcc3.3. (b) This should be used together with gcc3.4 to compile SciPy.

Then things will work on Tiger.

[erickt@…]

fixed to compile with gcc34 working

[erickt@…]

can this be integrated in the the release?
