Error building boost, cannot find -lpython

[francois.chenais@…]

An error occurs while linking

bin.v2/libs/python/build/gcc-4.1.2/release/debug-symbols-on/inlining-on/threading-multi/libboost_python-gcc41-mt-1_38.so.1.38.0

bjam pass -lpython instead of lib with version; -lpython2.4 for me. All others targets are built.

I'm on a centOS 5.2 with :

• python 2.4
• boost-jam 3.1.12

boost-1.38.0 building error

[Steven Watanabe]

Run

bjam --help python.init

for more info.

[francois.chenais@…]

I've tried setting

using python : 2.4 ;

in

tools/build/v2/user-config.jam

before reporting the bug. But without success.

The command line is

+ umask 022 + cd /home/cea/chenais/rpmbuild/BUILD + cd boost_1_38_0 + LANG=C + export LANG + unset DISPLAY ++ /usr/bin/python -c 'import sys; print sys.version[0:3]' + PYTHON_VERSION=2.4 + PYTHON_ROOT=/usr + EXPAT_INCLUDE=/usr/include + EXPAT_LIBPATH=/usr/lib64 + ICU_PATH=/usr + bjam -d2 --toolset=gcc variant=release debug-symbols=on inlining=on link=static,shared threading=multi

The attached file shows that bjam use 2.4 version of python.

Am I wrong ?

You may need a more recent version of boost-jam. Other than that, I have no idea what's going on. The build log refers to a libs/python/build/pythonlib target which I can't find any trace of in the source. My best guess is that the old version of bjam is causing the wrong build files to be selected.

I've tried with last bjam (3.1.17) but it fails with the same error.

Ok. Can you post the output from

    bjam --with-python --debug-configuration toolset=gcc link=static debug-symbols=on inlining=on threading=multi -n

[Vladimir Prus]

Francois, can you please provide output Steven has requested?
