Bug fixes

  • none

Known problems

  • on macOS, the /Library/Developer/CommandLineTools/usr/include/c++/v1 was added to the include path; unfortunately this may crash some builds; removed in 15.0.7-3
  • when clang is invoked via a link from a different folder, the InstalledDir does not reflect the correct install folder, and the new clang system headers are either not found or the host system headers are used; fixed in 15.0.7-4

Documentation

To save space and bandwidth, the original documentation is available online.

Build

The binaries for all supported platforms (Windows, macOS and GNU/Linux) were built using the xPack Build Box (XBB), a set of build environments based on slightly older distributions, that should be compatible with most recent systems.

The scripts used to build this distribution are in:

  • distro-info/scripts

For the prerequisites and more details on the build procedure, please see the README-MAINTAINER page.

CI tests

Before publishing, a set of simple tests were performed on an exhaustive set of platforms. The results are available from:

Tests

The binaries were tested on a variety of platforms, but mainly to check the integrity of the build, not the compiler functionality.

Deprecation notices

32-bit support

Support for 32-bit x86 GNU/Linux and x86 Windows will most probably be dropped in 2022. Support for 32-bit Arm GNU/Linux will be preserved for a while, due to the large user base of 32-bit Raspberry Pi systems.

GNU/Linux minimum requirements

Support for RedHat 7 will most probably be dropped in 2022, and the minimum requirement will be raised to GLIBC 2.27, available starting with Ubuntu 18 and RedHat 8.
