Hello, I'm having a lot of difficulty building boost on AIX6 with gcc. Searching for my problem just came up with a bunch of Windows users not settings their variables correctly. That does not seem to be the case for me. I'm dealing with v1.34.1, because apparently that works well on AIX. I had no problem building bjam. But then: -bash-3.2$ pwd /home/pats/boost-1.34.1 -bash-3.2$ ./tools/jam/src/bin.aix/bjam Unable to load Boost.Build: could not find build system. --------------------------------------------------------- /home/pats/boost-1.34.1/boost-build.jam attempted to load the build system by invoking 'boost-build tools/build/v2 ;' but we were unable to find "bootstrap.jam" in the specified directory or in BOOST_BUILD_PATH (searching /usr/share/boost-build, /home/pats/boost-1.34.1/tools/build/v2). Please consult the documentation at 'http://www.boost.org'. -bash-3.2$ ls -la /home/pats/boost-1.34.1/tools/build/v2/bootstrap.jam -rw-r--r-- 1 pats staff 761 Oct 29 2003 /home/pats/boost-1.34.1/tools/build/v2/bootstrap.jam Clearly the file is there. Setting explicit $BOOST_BUILD_ROOT and $BOOST_ROOT changes nothing, other than the error message output not mentioning /usr/share. So, the error message is lying, or there is something less obvious wrong. I had no issues building the same source tree on Suse and Solaris. Any advice? Many thanks, --Pat
