Hi there
Ok. There's something a little odd going on because when the output says that it's checking -lboost_filesystem-gcc41-mt-1_38, config.log says that it's checking -lgcc41-mt.
I see those two in different parts of the output.
Anyway, try running the link command manually and add -Wl,--verbose to see exactly what files the linker searches for.
I don't see the link command logged anywhere .. running the g++ commandline directly doesn't help, since conftest.cpp doesn't exist .. I guess it only exists during the build process.
From the logfile, here are two other unrelated ld failures:
""" configure:22229: gcc -o conftest -g -O2 -I/home/zope/local/include/boost-1_38 conftest.c -lpthreads >&5 /usr/bin/ld: cannot find -lpthreads configure:22229: gcc -o conftest -g -O2 -I/home/zope/local/include/boost-1_38 conftest.c -llthread >&5 /usr/bin/ld: cannot find -llthread """ Here are the two relevant-looking ones: """ configure:23688: checking for exit in -lgcc41-mt configure:23723: g++ -o conftest -g -O2 -I/home/zope/local/include/boost-1_38 -I/usr/include -L/home/zope/local/lib conftest.cpp -lgcc41-mt >&5 /usr/bin/ld: cannot find -lgcc41-mt configure:23688: checking for exit in -lboost_filesystem-gcc41-mt configure:23723: g++ -o conftest -g -O2 -I/home/zope/local/include/boost-1_38 -I/usr/include -L/home/zope/local/lib conftest.cpp -lboost_filesystem-gcc41-mt >&5 /usr/bin/ld: warning: libboost_system-gcc41-mt-1_38.so.1.38.0, needed by /home/zope/local/lib/libboost_filesystem-gcc41-mt.so, not found (try using -rpath or -rpath-link) /home/zope/local/lib/libboost_filesystem-gcc41-mt.so: undefined reference to `boost::system::get_system_category()' /home/zope/local/lib/libboost_filesystem-gcc41-mt.so: undefined reference to `boost::system::get_generic_category()' """ I don't understand those last three lines: libboost_filesystem-gcc41-mt.so is a symlink to libboost_system-gcc41-mt-1_38.so.1.38.0, so how can the first one be found and not the second? -- jean . .. .... //\\\oo///\\
