Hi, I have tried to build the current boost library as checked-out of the CVS repository, but I failed miserably. For one, the build process failed to recogize that Python is installed in /usr/local/python rather than /usr/local. As a result, it didn't find the python-specific include files either. I tried to set the appropriate environment variables but failed. So I added the directory /usr/local/python/include/python2.2 to CPLUS_INCLUDE_PATH and then it worked -- at least a little better than before. Once the Python includes were found, the build process progressed to actually linking some programs: gcc-Link-action status/bin/config_test.test/gcc/debug/runtime-link-dynamic/threading-multi/config_test status/bin/config_test.test/gcc/debug/runtime-link-dynamic/threading-multi/config_test.o: In function `boost_has_clock_gettime::f()': /home/simons/projects/boost-current/libs/config/test/boost_has_clock_gettime.cxx:19: undefined reference to `clock_gettime' collect2: ld returned 1 exit status Another failure was: ...failed gcc-Link-action status/bin/config_test.test/gcc/release/runtime-link-dynamic/threading-multi/config_test ... gcc-C++-action status/bin/class_concept_fail_expected.test/gcc/debug/runtime-link-dynamic/class_concept_fail_expected.o /home/simons/projects/boost-current/boost/concept_check.hpp: In member function `void boost::EqualityComparableConcept<TT>::constraints() [with TT = foo]': /home/simons/projects/boost-current/libs/concept_check/class_concept_fail_expected.cpp:25: instantiated from here /home/simons/projects/boost-current/boost/concept_check.hpp:265: no match for `foo& == foo&' operator /home/simons/projects/boost-current/boost/concept_check.hpp:266: no match for `foo& != foo&' operator Plenty of files failed to compile or to link, but I don't want to flood the list with error messages. So, first of all, is there any "right" way to tell the build process where python is installed? Maybe I should start from the scratch from there. -peter
