error when installing octave

[prowe@…]

I get the following error for >>sudo port install octave:

--->  Building octave
Error: org.macports.build for port octave returned: command execution failed
Please see the log file for port octave for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_math_octave/octave/main.log

Error: Processing of port octave failed

I'm on a new MacPro with Mavericks. Here are the steps I took:

• Install Xcode
• Open Xcode

1. Type xcode-select --install
2. Install Macports on Mac
   https://www.macports.org/install.php
   Click on “OS X 10.9 Mavericks” for automatic download.
3. Type “sudo port install hdf5”
4. Type “sudo port install netcdf”
5. Type “sudo port install netcdf-cxx” for C++ interface
6. Type “sudo port install netcdf-fortran” for Fortran interface
7. Type “sudo port install libgcc”
8. Type “sudo port install gcc47”
   Couldn’t successful load “atlas” package using either gcc49 or gcc48.
   So tried to follow this
   #40542
9. Type “sudo port clean atlas”
10. Type “sudo port -v install atlas +gcc47”
11. Type “sudo port install octave”

Thank you for any help!

Please attach the main.log file.

I would expect you’d need to specify a GCC variant for hdf5, netcdf, netcdf-cxx, and netcdf-fortran, at the very least.

Why would I need to specify a gcc variant?

The steps I took worked fine for my colleague, I think on a Mac Air, except for the atlas part as outlined in the steps. It worked fine on my Mac laptop (and no atlas problems there).

Replying to prowe@…:

Why would I need to specify a gcc variant?

You cannot mix C++ runtimes. Binaries built with clang++ / libc++abi should not link against binaries built with g++ / libsupc++. Even if they link “properly”, you will experience runtime issues and crashes.

I'm new at this; do I specify a gcc variant by appending +gcc47; e.g. sudo port install hdf5 +gcc47? Should I also append a -clang?

Thanks so much for your help!

[prowe@…]

I tried uninstalling everything and reinstalling with +gcc47 for hdf5, netcdf, netcdf-cxx, and netcdf-fortran, but that did not work. I think the error message at the end was the same.

Next I uninstalled everything again and reinstalled with +gcc47 and - any default variants (which I found using sudo port variants). Same error message. The main.log file differs only slightly.

[mf2k (Frank Schima)]

Why are you using gcc47? Try gcc48 which is the default in Macports. Also I would suggested re-installing ld64 and cctools since they recently changed default variants to use llvm-3.5.

As far as hdf5 goes, there is no "clang" variant so there is no need to specify "-clang".

FYI, since Trac is not for tech support, follow-up on the ​Macports Users mailing list instead and you will get a much wider audience to help you.

Can you try:

sudo port clean octave
sudo port install octave

and see if that helps. If not, what does "xcodebuild -version" return for you? I'm wondering if this might be a result of Xcode 6 ... which I don't have yet.

[Schamschula (Marius Schamschula)]

The main.log file says it all: a duplicate of #45011 - Xcode 6.0.1 issue.

Thanks; I'm closing this one & will work on the other ticket instead.
