boost @1.55.0: patch phase fails with python3x variants

[tamyrvoll@…]

Upgrading boost 1_54_0 to 1_55_0 fails. I have attached the log-file.

Specifics about my system that may be of relevance:

• My Macports installation resides on a separate volume with a link from /opt/local
• I have "sandbox_enable no" in my macports.conf
• Current boost is installed as "boost @1.54.0_0+no_single+no_static+python33"

Oops, I didn't test the python3x variants.

I tried removing the patch, and when installing with +python33 +openmpi, the build succeeded, but destroot failed with:

Error: org.macports.destroot for port boost returned: error renaming "/opt/local/var/macports/build/_Users_rschmidt_macports_dports_devel_boost/boost/work/destroot/opt/local/lib/mpi.so": no such file or directory

so I guess the patch is still needed, but I don't know how to update it for boost 1.55.0. Mark, do you? You originally added the patch in #39193.

That's weird. If I remove the patch, destroot and install work fine for me (on Mavericks with latest Xcode). Does mpi.so exist anywhere in your build directory?

I did notice some small unrelated problem. In python3 the import statement has changed. The following one-line change is necessary for boost+python3X:

The python3 patch, patch-boost-python3.diff, attempts to patch two files:

• libs/mpi/src/python/datatypes.cpp
• libs/mpi/src/python/py_environment.cpp

The patches for the second file, are unnecessary [see the source code]. I removed the unnecessary patches and built the python33 variant:

boost @1.55.0_0+no_single+no_static+python33 (active)

SYSTEM: dual G4 PowerMac OS X 10.5.8

Boost 1.55 builds on a PPC-based PowerMac using macports-gcc-4.8

• boost @1.55.0_0+no_single+no_static+python27
• boost @1.55.0_0+no_single+no_static+python33 (active)

To do so, edit ./tools/build/v2/tools/darwin.jam to eliminate the "-arch" option, which is not supported by the MacPorts compiler. The python33 variant requires the changes to patch-boost-python3.diff specified in comment #5.

drjesacco, can you create a patch for ./tools/build/v2/tools/darwin.jam? For which compilers exactly is this patch necessary? I have summarized the required changes to the Boost Portfile and patches in patch-boost.diff.

ryandesign, can you provide any more information about your setup? I can't replicate your problem.

I have committed my patch in r114354. ryandesign, can you confirm this fixes things for you?

[ryandesign (Ryan Carsten Schmidt)]

"sudo port install boost +python33 +openmpi" fails during destroot with "error renaming "/opt/local/var/macports/build/_Users_rschmidt_macports_dports_devel_boost/boost/work/destroot/opt/local/lib/mpi.so": no such file or directory". I'll attach the main.log.

[mamoll (Mark Moll)]

One problem seemed to be that with the python3X variants, the correct python interpreter wasn't used. It would fall back on the "python" interpreter in the path, which in my case is python3.3, but ryandesign's case corresponds to python2.7. I am not sure if that completely fixes the problem, but it was definitely a bug. Fixed in r114377.

Good catch. Works for me!
