[release] 1.74.0 open for merging
by Marshall Clow 28 Apr '20

28 Apr '20

The master branch is open for merging all stable changes from develop, including bug fixes and major upgrades to existing libraries. Breaking changes should be coordinated via the mailing list with the developers of the other libraries affected. New libraries may be added, but require permission of a release manager. In other words, merging does not require permission from a release manager, except for new libraries.

Controlling _BOOST_CMAKEDIR in installed .cmake files
by Jonathan Wakely 24 Apr '20

24 Apr '20

With Peter Dimov's help I've resolved my earlier problems packaging Boost for Fedora. Now my problem is that the generated .cmake files contain the full --prefix path, which is not what I want because that's just a staging area, not the final resting place for the files (think DESTDIR in an autotools build). I see lines like this in each of the installed .cmake files: /builddir/build/BUILDROOT/boost-1.73.0-0.1.fc33.x86_64/usr/lib64/openmpi/lib/cmake/boost_python-1.73.0/boost_python-config.cmake:if(EXISTS "/builddir/build/BUILDROOT/boost-1.73.0-0.1.fc33.x86_64/usr/lib64/openmpi/lib/cmake") /builddir/build/BUILDROOT/boost-1.73.0-0.1.fc33.x86_64/usr/lib64/openmpi/lib/cmake/boost_python-1.73.0/boost_python-config.cmake: get_filename_component(_BOOST_CMAKEDIR_ORIGINAL "/builddir/build/BUILDROOT/boost-1.73.0-0.1.fc33.x86_64/usr/lib64/openmpi/lib/cmake" REALPATH) /builddir/build/BUILDROOT/boost-1.73.0-0.1.fc33.x86_64/usr/lib64/openmpi/lib/cmake/boost_python-1.73.0/boost_python-config.cmake: set(_BOOST_CMAKEDIR "/builddir/build/BUILDROOT/boost-1.73.0-0.1.fc33.x86_64/usr/lib64/openmpi/lib/cmake") These files won't work after everything gets moved from the staging area $RPM_BUILD_ROOT/usr/... to the final lcoation on a user's machine, under /usr/... I can just use sed to alter them, but surely there's way to set the desired prefix? I'm trying: ./bootstrap.sh --with-toolset=gcc --with-icu --prefix=/usr ./b2 -d+2 -q -j 4 \ --without-mpi --without-graph_parallel --build-dir=serial \ --prefix=/usr --libdir=/usr/lib64 \ variant=release threading=multi debug-symbols=on pch=off \ python=3.8 \ stage ... ./b2 -d+2 -q -j 4 \ --without-mpi --without-graph_parallel --build-dir=serial \ --prefix=$RPM_BUILD_ROOT/usr \ --libdir=$RPM_BUILD_ROOT/usr/lib64 \ variant=release threading=multi debug-symbols=on pch=off \ python=%{python3_version} \ install And this produces the .cmake files with the unwanted $RPM_BUILD_ROOT/usr prefixes. I originally didn't have the --prefix and --libdir options on the bootstrap.sh command and the 'b2 .. . stage' command, but it doesn't seem to matter whether they're there or not. Is there some way to control the prefix that ends up in those .cmake files?

10 slots for the Google Summer of Code 2020
by David Bellot 22 Apr '20

22 Apr '20

Hi Boost community, this year Google allocated 10 slots for the Google Summer of Code. It's again a great achievement thanks to the hard work of our team of dedicated mentors. We are now selecting the best students among all the proposals we receive. We received 79 proposals this year. 10 of them will be selected. This year, a lot of proposals if not all are targeting a finalization of the work which has been done in the previous GSoCs and we should see a lot of code being pushed in production. It's a very exciting time for all of us. The mentors are now hard at work to choose the students. We'll keep you informed when it's official. Best regards, David

MySQL ASIO library
by Ruben Perez 22 Apr '20

22 Apr '20

Hi all, I have been writing an ASIO-based client for MySQL, trying to mimic what Beast is to HTTP. It currently supports SQL queries and prepared statements. It can be viewed here: https://github.com/anarthal/mysql-asio Do you guys think this has the potential to be useful or become part of Boost long term? Any feedback is very welcome. Thanks, Ruben (Anarthal).
