Last week, a new LTS kernel (4.9.26), new glibc (2.25) and a new gcc compiler suite (7.1.0) landed in Slackware-current. Note that gcc no longer contains the Java compiler (gcj): subsequently Slackware’s gcc-java package has been removed from slackware-current.
We are at the head of the herd again folks. There is not yet any other distro that ships with the gcc-7 compiler by default. This will certainly pose some challenges for people who compile their stuff themselves – the SBo team warned their community about scripts that require patches to compile against gcc-7.
I have my set of challenges myself too… until now, I have not been able to compile the multilib versions of the gcc compiler suite. That’s infuriating, I can tell you. Specifically, I have issues with brig, gnat, go and objc compilers; the 7.1.0 versions of c and c++ compilers are just fine. I hope to resolve this soon-ish… until then, you will have to wait for new multilib compilers. If you really need a gcc 7.1.0 compiler (for instance, to compile a kernel module) I suggest that you (temporarily) switch to Slackware-current’s gcc 7.1.0 packages. Running your multilib system is of course not affected by this – gcc is only needed to compile stuff. I will probably release glibc-2.25_multilib packages ahead of the problematic gcc multilib packages to give you at least something.
Another interesting addition is lame. After the last Fraunhofer MP3 patent expired on 16 April 2017, the doors were opened to enable MP3 encoding support in Slackware. Several packages have been recompiled to take advantage of the new MP3 encoding capability (cdrdao, sox, ffmpeg, MPlayer, audacious-plugins) and the gstreamer packages were updated for good measure.
