Options for building the Boost libraries with bjam seem to have changed from 1.33 to 1.34. At least, I can't be sure that the result will be the same. I looked at the 1.34.0 beta docs and the common.jam and gcc.jam files, but I am still unsure of what to do. I built the 1.33.x libraries this way: setenv PYTHON_VERSION 2.3 bjam -sTOOLS=gcc -sGCC_ROOT_DIRECTORY=/opt/gcc344 -sGXX="g++344 -m64" -sGCC="gcc344 -m64" --with-python-root=/usr --stagedir=stageFC3 -sBUILD="debug release <threading>multi <shared-linkable>true <instruction-set>opteron" stage Most of the options make it obvious what I want. The '<shared-linkable>true' option was necessary to add '-fPIC', which our binaries need in order to dynamically link (plug-in) shared libraries. I will appreciate any help you can offer in making the transition to 1.34.0 easier. BTW, it would be nice to see a list of available options for each toolset that comes with Boost bjam. -- Dick Hadsell 914-259-6320 Fax: 914-259-6499 Reply-to: hadsell@blueskystudios.com Blue Sky Studios http://www.blueskystudios.com 44 South Broadway, White Plains, NY 10601
