Boost 1.68 not compiling on mac

O²
1

Dear experts,

With the latest update of macOS from last week I get a compilation error of boost 1.68 on mac - 1.69 however works fine. You can find the logs below (only relevant lines raising the errors). I am using the build recipes of yesterday’s master building with the O2 defaults. As far as I understand DDS is not compatible with 1.69 yet (due to changes in boost-system) - any chance that it get compatible soon?

Cheers

Markus

If it is ok for you, you can remove boost installed by brew. It will then work.

For the rest, I let others answer.

Cheers,

Thanks Barth for the quick reply, but uninstalling boost from brew is not an option - I might need it for something else.

After some investigation I figured out that the following line is responsible for including the header files from the homebrew boost:

export CPLUS_INCLUDE_PATH="$CPLUS_INCLUDE_PATH:$(python3 -c ‘import sysconfig; print(sysconfig.get_path(“include”))’)"

It’s probably linked to the python coming from homebrew as well. I don’t fully understand this because the include path points to the path in the Cellar subdirectory and not to /usr/local/include. As nevertheless python is disabled on OSX can we disable this line with if [ $ARCHITECURE == … ] …?
