Yes, I’m using anaconda and have set up automated builds for JCC packages (win/mac/linux) for it at:https://github.com/conda-forge/jcc-feedstock
I do not remember seeing your issue in the build, but check your compile parameters to the ones in the build script:https://github.com/conda-forge/jcc-feedstock/blob/master/recipe/build.sh
The version that is in that feedstock is the 3.0 release version, the current svn version (as of feb) built as well but had some issues with object casting so have not put that on the feedstock.
If you don’t need to build it yourself you can install it with conda search jcc --channel conda-forge
With Best Regards
