py25-scipy-0.6.0_2 build failure

[harrylparker@…]

I have been having trouble for several weeks upgrading port py25-scipy.

Today I did a port selfupdate and successfully upgraded g95 and tried to upgrade py25-scipy from from version 0.6.0_0. The attempted upgrade ends with:

building 'scipy.interpolate.dfitpack' extension
error: extension 'scipy.interpolate.dfitpack' has Fortran sources but no Fortran compiler found

Warning: the following items did not execute (for py25-scipy): org.macports.destroot org.macports.build
Error: Unable to upgrade port: 1

I tried this with the default variant and with the +g95 variant set explicitly.

This is on a PowerPC G4 recently upgraded to Mac OS X 10.4.11.

strange as it looks like it can't find a fortran compiler, can you attach the full output of

$ sudo port -d install py25-scipy

to the ticket? along with

$ port installed

[ram@…]

I can't understand this, as from the build log it successfully compiles fortran code earlier in the build process but can't find the fortran compiler later on... I use the gcc42 variant, as I haven't been able to get g95 to build on Intel Leopard, so I'm unable to duplicate this.

Can you attach the build log again, this time using the -d option instead of the -v option to port as that should tell me in which phase the error is occurring in, i.e. build or destroot

I performed the following command as ram requested. The complete screen output is shown. The redirected output file will be attached to this ticket.

The redirected output of "sudo port -d install py25-scipy > py25-scipyInstallDebugOutput.txt".

[ram@…]

This is very odd, the error is occurring in the build phase - yet earlier in the build phase the fortran compiler is used to compile fortran source code without issue... I'll try to reproduce the problem.

[harrylparker@…]

Last night I tried another install of py2-scipy. This time I first deactivated the activated version and cleaned out the the previous build results. Then I saved the stdout and stderr together. This resulted in in a much larger, 238 KB log file, fullCleanScipyInstallLog.txt. (The previous stdout + screen output totalled 20 KB.)

Here is the transcript of what I did:

Harrys-Silver-PowerBook:~ hparker$ sudo port -v uninstall py25-scipy

Harrys-Silver-PowerBook:~ hparker$ bg

Harrys-Silver-PowerBook:~ hparker$ tail fullCleanScipyInstallLog.txt

Then I kept an eye on my activity monitor and continued to use tail to see what was happening.

I hope this new log file helps.

I've managed to get g95 built and I get the same error when trying to build the default g95 variant... I'm looking into it.

[ram@…]

Just an update on this, I still can't work out why the build is failing - I've asked the upstream developers but haven't heard anything back from them... In the meantime try using the gcc42 variants of numpy and scipy as they build fine

[ram@…]

Heard back from the upstream developers, it turns out that g95 is not a supported compiler on the Mac OS X platform as the appropriate linking flags have not been implemented. So until these have been implemented I'm going to remove the g95 variant and make numpy/scipy depend only upon gcc42. Should be committed shortly.
