boost/python/detail/caller.hpp doesn't compile (no member named 'get_pytype')

[Ingmar Vanhassel <ingmar@…>]

When compiling vegastrike-0.5.0 against boost 1.39.0 (./configure --with-boost=system to use the system boost instead of internal copy), the build breaks on errors in the boost/python/detail/caller.hpp header:

Labelling this as regression since vegastrike is known to compile with boost 1.36.0.

I'm using GCC 4.4.0, glibc 2.10.1, python 2.6.1 on Exherbo Linux

[troy d. straszheim]

marking [fix in git] as detail/caller.hpp is completely overhauled there.

[Dave Abrahams]

Reassigning, since I don't know what to do with a bug marked "fixed in git."

[troy d. straszheim]

The others marked [fix in git] come with urls of commits to my git branch that fix the problem. These [fix in git] tags were notes to self as I attempted to get all bugs fixed on my branch prior to a "merge to trunk".... ugh. I'll just unmark these [fix in git] things.

I'll take the bug. Can anybody verify that this is still broken?

[Dave Abrahams]

Leave any marks you want as long as you claim the tickets ;-)

This is the same one, isn't it?

[Dave Abrahams]

hard to know. A minimal reproducable test case would help a lot

[Nicolas Kaiser <nikai@…>]

I tried to build against system Boost 1.35.0, but failed with the same error. I had a look at the differences between 1.35 in-tree and system 1.35, but couldn't find any interesting ones.

Then I noticed that my build system swallowed the below flag:

vegastrike/m4scripts/VS_WITH_BOOST.m4, lines 15 and 29:

BOOST_CPPFLAGS='-I/usr/include -DBOOST_PYTHON_NO_PY_SIGNATURES '
(..)
AC_DEFINE(BOOST_PYTHON_NO_PY_SIGNATURES,1,[needed for get_pytype])

With this one added it's working for me against 1.41.0.

So, what's the status of this bug?

Igmar (if you're still here) - are you still having this problem with a recent boost?

Troy - did your fixes ever get merged into the SVN depot?

Nicolas - sounds like you're building successfully.

Is there still a problem here?

[anonymous]

Still having this problem with following software versions:

• VegaStrike Revision: 13202
• boost 1.47.0
• gcc 4.6.1
• glibc 2.13

vegastrike ./configure allows python only up to 2.5 . tested with python 2.4 and 2.5
