Multilib gcc updated to address changes in slackware-current

April 25, 2015 / / 11 Comments

slackware_multilib

In slackware-current two inter-related packages were updated yesterday: libmpc and gcc. It turns out that the update of libmpc caused a library version change. Since the gcc compiler is dynamically linked to libmpc, the gcc packages had to be recompiled in order to make it link against the new libmpc.so.3 library. Another reason for recompiling the gcc package was the missing libiberty.a file. The gcc.SlackBuild needed an additional configuration parameter to make it install into the package again.

Unfortunately that slackware-current update broke the multilib gcc packages which I have in my own repository, as several people noticed … the quick’n’dirty fix was (cd /usr/lib64 ; ln -s libmpc.so.3 libmpc.so.2).

I have recompiled the multilib gcc twice (after applying Slackware’s updates to the gcc-multilib.SlackBuild): first compilation was done with that symlink created like I just described. That resulted in the desired linkage to the new libmpc.so.3 library. Then I removed the symlink which I had created earlier and compiled the gcc packages again, just to be sure (for Slackware, this double compilation was performed as well).

The new gcc packages are now online, along with an update to the massconvert32.sh script which is part of the compat32-tools package. Also I refreshed the set of 32-bit “compat32” packages which I create from the official 32-bit Slackware package tree, because there were several updated packages in Slackware (again), and I added the libva-intel-driver-compat32 package on request.

Here is where you can find the updated packages:

If you wonder what this multilib is all about: it is needed if you want to use (binary-only) 32-bit software on 64-bit Slackware. Examples of that are Skype, Valve’s Steam Client, the WINE emulator, the Pipelight browser plugin, Citrix client etc.

Instructions on how to add or update multilib on your 64-bit Slackware can be found on the Slackware Documentation Project. Also, the slackpkg+ extension to Slackware’s own slackpkg contains the script “setupmultilib.sh” which can help you in setting up multilib properly.

 

Enjoy! Eric

Multilib glibc patched for GHOST vulnerability (CVE-2015-0235)

January 30, 2015 / / 13 Comments

There was some unrest about the most recent glibc update in the stable releases of Slackware (slackware-current excluded). Glibc was patched against a new vulnerability, CVE-2015-0235, for which the only known exploit currently is in the MTA Exim (software which is not part of Slackware) and an exploit for this vulnerability is difficult to write apparently. I usually am quite fast in following up on Slackware updates for gcc and especially glibc. This time, I was busy with answering questions about the new KDE 5 at night, and buried in shit at work during the day.

Nevertheless, when there were no updated multilib versions of glibc the next day, some people asked when they could expect a patched package. Others were less polite and demanded updated packages. That sucked.

Here is where you can find the updated packages:

For the un-initiated: multilib is needed if you want to use binary-only 32-bit software on 64-bit Slackware. Examples of that are Skype, Valve’s Steam Client, the WINE emulator, the Pipelight browser plugin, Citrix client etc.

Instructions on how to add or update multilib on your 64-bit Slackware can be found on the Slackware Documentation Project.

Slackware-current – new multilib gcc compiler suite

June 3, 2014 / / 5 Comments

The latest update to Slackware-current brought us a new kernel (3.14.5) and a new gcc compiler (4.8.3).

This warranted a build of new multilib gcc packages. Get them from your nearest mirror. I also refreshed the “compat32” layer of packages – this is the set of converted 32-bit Slackware packages which you’ll need at a minimum, so that you will be able to run most of the 32-bit software that is out there.

Remember, a multilib configuration is needed if you want to use binary-only 32-bit software on 64-bit Slackware – think of Valve’s Steam Client, the WINE emulator, the Pipelight browser plugin, Citrix client etc.

If you are looking for instructions on how to add or update multilib on your 64-bit Slackware, check out our Slackware Documentation Project which has this information and much more.

Cheers, Eric

 

New multilib versions of glibc and gcc for slackware-current

May 9, 2014 / / 26 Comments

There were a couple of nice updates in the Slackware-current ChangeLog today – new kernel (3.14.3), new binutils (2.24.51.0.3), new glibc (2.19) and a rebuilt gcc. Not to speak of two new packages: libnftnl and nftables, which bring a new packet filtering framework on Linux.

It’s my birthday today and I took a day off to be with my family, so there was time enough to build new versions of multilib glibc and gcc :-). They are at their usual download locations:

Rebuild for glibc-2.17_multilib in slackware-current

April 21, 2013 / / 0 Comments

Pat’s inquery on LinuxQuestions.org about how to “backtrack to sanity” in order to stabilize slackware-current and start laying out the next release, resulted in a kernel upgrade (3.8.8) and accompanying glibc rebuild.

I built the “companion” update of the glibc multilib packages last night. They can be downloaded from:

Remember, multilib configuration is (only) needed if you want to use binary-only 32-bit software on 64-bit Slackware – think of Valve’s Steam Client, the WINE emulator, Citrix client etc.
