Hello all,

A few of us with Boost are trying to decide support of different

compilers. I know that Ubuntu collects some anonymized statistics which could help us some. Could someone please collect and forward the following bits of information to boost@lists.boost.org :

...

Install base size of Ubuntu 14.04 to 19.04 Per OS version, what versions of GCC, Clang, and Boost are installed on what percentage of the install base. -- ubuntu-devel mailing list ubuntu-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel

From Ubuntu development point of view, our biggest concern is that no stable releases of boost claim to be supported or tested with the next GCC compiler.

For example, for 19.10 we will be switching to GCC-9 by default, yet boost 1.70.0 primary test compilers do not include GCC-9 for Linux. Ideally, we would like to see boost upstream include next-gcc as part of primary or additional test compilers for every boost release.

I run all the teeks99-* testers that can be found in the test matrix [1] [2]. All these runners are docker instances based on scripts found in my repo [3] (get them from the hub [4]) which in turn are based on these [5]. These are all based on Ubuntu LTS releases. For the released compiler for each release that is used in the image, but for most gcc versions I use the compiler from the PPA for Toolchain Test Builds [6]. I've been waiting with baited breath for a gcc-9 build for bionic to be pushed up to there (and even an update to the gcc-8 for point releases!). If you can make that happen (or point me towards an alternative?) I can get tests running against gcc-9 in short order.

LLVM is a much easier setup. That project provides their own builds of llvm/clang for ubuntu [7], for every release, point release, and even nightly master. Ideally someone should setup something similar for GCC, but I don't think I'll have time to take that on in the near future.

gcc-9 (teeks99-dkr-dg9-2a and teeks99-dkr-mg9-2a) is now in the test matrix. gcc-8 (numerous runners) has been updated to 8.3. I'm going to let the gcc-9 jobs gel for a bit more time, then I'll move the bulk of the "current" test runners to that. Thanks to Dimitri for helping get the PPA updated. Tom
