Today I was looking around for a bug in autoconf, and I noticed one interesting bit out of the NEWS file of the current git version:

Present But Cannot Be Compiled: Autoconf will now proceed with the compiler’s result if a header is present but cannot be compiled. The warning is still printed, and you should really fix it by providing a fourth parameter to AC_CHECK_HEADER/AC_CHECK_HEADERS.

This is a tremendously useful thing to know before autoconf 2.64 is released, which is hopefully not too soon. The reason for this is that finally, after years of having that as a warning, to the point that some projects even ignored it altogether, the new autoconf will start ignoring header files that cannot be compiled, for whatever reason. This is useful since it ensures that headers are not detected that lacks proper dependencies. Unfortunately this also means that any software that currently relies on header files found without compilation will change behaviour.

    Cockpit is the modern Linux admin interface. There’s a new release every week. Here are the highlights from this weeks 0.104 release.
  • FFmpeg 3.0.2 "Einstein" Multimedia Framework Released with Updated Components
    Today, April 28, 2016, the development team behind the popular FFmpeg open-source and cross-platform multimedia framework has released the second maintenance release in the stable FFmpeg 3.0 "Einstein" series. FFmpeg 3.0 was a massive release announced in mid-February, which brought in numerous existing changes, including support for decoding and encoding Common Encryption (CENC) MP4 files, support for decoding DXV streams, as well as support for decoding Screenpresso SPV1 streams.
  • Using bubblewrap in xdg-app
    At the core of xdg-app is a small helper binary that uses Linux features like namespaces to set up sandbox for the application. The main difference between this helper and a full-blown container system is that it runs entirely as the user. It does not require root privileges, and can never allow you to get access to things you would not otherwise have.
  • Build System Fallbacks
    If you are using Builder from git (such as via jhbuild) or from the gnome-builder-3-20 branch (what will become 3.20.4) you can use Builder with the fallback build system. This is essentially our “NULL” build system and has been around forever. But today, these branches learned something so stupidly obvious I’m ashamed I didn’t do it 6 months ago when implementing Build Configurations.
  • Node.js version 6 is now available
