Also, the cctbx conda packages are already using Boost 1.74, so that version should be fine. The issue is when we are building the libraries from source. -- Billy K.

Hey Rob,

Can you try the boost174 branch in cctbx_project? I added some changes for building boost. This branch should work for Boost 1.72 ( https://dev.azure.com/bkp4/cctbx_project/_build/results?buildId=1833&view=results) and 1.74 ( https://dev.azure.com/bkp4/cctbx_project/_build/results?buildId=1834&view=results). I'm running a "Full" build for Boost 1.74.

The error is from not building all the source files for the filesystem module. I add the extra files in https://github.com/cctbx/cctbx_project/commit/5fa38c8433b52754f1360888f83384...

I started testing this last year, but it looks like it should be fine.

Hi,

I'm testing newer versions of boost than 1.70 currently distributed with CCTBX. I can't remember if I have to do something special other than unpacking the zip file, say boost_1_74_0.zip, that I download from boost.org and put it into the modules directory for my cctbx build. But I get several errors during build like:

C:\Users\Oeffner\OeffnerStuff\Work\PhenixVoyager\modules\boost\libs\filesystem\src\codecvt_error_category.cpp(71): error C2491: 'boost::filesystem::codecvt_error_category': definition of dllimport function not allowed

I'm have tried with the VS2015, VS2017 and the VS2019 compiler and they all complain. So I'm wondering if there are some other magic invocations that have to be done before building with a new version of boost.

Thanks in advance for any suggestions,

Rob
