If you look at
http://beta.boost.org/development/tests/trunk/developer/output/Caleb%20Epstein%20SunOS-5-10-boost-bin-v2-libs-python-test-exec-test-gcc-4-1-2_sunos_i86pc-debug-debug-symbols-off-thrd-api-pthread_release.html
you'll see the following command line:
"/openpkg/bin/g++" -L"/openpkg/lib"
-L"/openpkg/lib/python2.5/config" -Wl,-R -Wl,"/openpkg/lib" -Wl,-R
-Wl,"/openpkg/lib/python2.5/config" -o
"/home/cae/boost-regression/svn-trunk/results/boost/bin.v2/libs/python/test/exec.test/gcc-4.1.2_sunos_i86pc/debug/debug-symbols-off/thrd-api-pthread/exec"
-Wl,--start-group
"/home/cae/boost-regression/svn-trunk/results/boost/bin.v2/libs/python/test/exec.test/gcc-4.1.2_sunos_i86pc/debug/debug-symbols-off/thrd-api-pthread/exec.o"
"/home/cae/boost-regression/svn-trunk/results/boost/bin.v2/libs/python/build/gcc-4.1.2_sunos_i86pc/debug/debug-symbols-off/link-static/thrd-api-pthread/libboost_python-gcc41-d-1_35.a"
-Wl,-Bstatic -lrt -ldl -Wl,-Bdynamic -lpython2.5 -lrt -ldl
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Wl,--end-group -Wl,--strip-all
On that platform there is no static librt, and the link fails.
The only substantial difference between the way the exec target above
is declared and a similar one that works, is that the exec target
explicitly asks for the static version of the Boost.Python library.
Here's the target that worked:
"/openpkg/bin/g++" -L"/openpkg/lib"
-L"/openpkg/lib/python2.5/config" -Wl,-R
-Wl,"/home/cae/boost-regression/svn-trunk/results/boost/bin.v2/libs/python/build/gcc-4.1.2_sunos_i86pc/debug/debug-symbols-off/thrd-api-pthread"
-Wl,-R -Wl,"/openpkg/lib" -Wl,-R -Wl,"/openpkg/lib/python2.5/config"
-Wl,-rpath-link
-Wl,"/home/cae/boost-regression/svn-trunk/results/boost/bin.v2/libs/python/build/gcc-4.1.2_sunos_i86pc/debug/debug-symbols-off/thrd-api-pthread"
-o
"/home/cae/boost-regression/svn-trunk/results/boost/bin.v2/libs/python/test/pointee.test/gcc-4.1.2_sunos_i86pc/debug/debug-symbols-off/thrd-api-pthread/pointee"
-Wl,--start-group
"/home/cae/boost-regression/svn-trunk/results/boost/bin.v2/libs/python/test/pointee.test/gcc-4.1.2_sunos_i86pc/debug/debug-symbols-off/thrd-api-pthread/pointee.o"
"/home/cae/boost-regression/svn-trunk/results/boost/bin.v2/libs/python/build/gcc-4.1.2_sunos_i86pc/debug/debug-symbols-off/thrd-api-pthread/libboost_python-gcc41-d-1_35.so.1.35.0"
-Wl,-Bstatic -Wl,-Bdynamic -lpython2.5 -lrt -ldl -Wl,--end-group
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Wl,--strip-all
I can probably suppress the error by not explicitly requesting a
static boost.python library for the exec target, but I think this
indicates a serious bug in Boost.Build.
Could someone take a look at this and try to determine why it's
happening and see if we can fix it in Boost.Build?
Thanks,
