Hi Rob, Are these features required before anything is built? Or are they dependencies for Phaser that get linked during building? Can you send me your SConscript file? -- Billy K.

We are working on a newer version of Phaser. The new SConscript file for Phaser imports features from boost_python. Therefore it is currently not straightforward to build it since an empty build directory does not yet contain the boost_python module to be imported by SConscript (or python). So SCons crashes when it reads the new Phaser SCsonscript stating that boost_python cannot be imported. Currently our workaround is to first build CCTBX alone and then subsequently to build Phaser.

My question is if it is possible to specify dependencies in cctbx_project/boost_adaptbx/SConscript to force building boost_python early on. On Windows boost_thread and a few other libraries are built before other SConscript files are read. So I have put some Depends(boost_thread, boost_python) andDepends(boost_thread, boost_python_meta_ext) statements into cctbx_project/boost_adaptbx/SConscript. These do seem to force building the boost_python.lib and .dll files. But building the boost_python_meta_ext python module fails with the error: boost_adaptbx\meta_ext.cpp(14): fatal error C1083: Cannot open include file: 'boost_adaptbx/type_id_eq.h'

It's possible that I'm not using SCons as it's supposed to be used. Let me know if anyone has a suggestion on how to force building boost_python before other SConscript are read.

Many thanks,

Rob

Is there any real reason why we can't build boost earlier using their own installers - e.g. as part of the base? Baseless builds can install it the same way they install any other dependencies. Conda can just install boost the same way it does any other dependency. I've always thought it strange the way we replicate the build process, It would save a lot of time that we waste every time boost updates and having to debug problems caused by not replicating the build properly (on linux *and* windows).

Hi Rob, The SCons environment used to build the Boost libraries does not have any of the cctbx include’s. Hence the error you get: SCons does not tell the compiler to look in boost_adaptbx for headers when building boost_thread and the like but then you have now asked SCons. I am not sure I understand why you need to make boost_thread depends on boost_python_meta_ext actually. Best wishes, Luc
