I am setting up a new Tumbleweed system, and I see that gcc-8 (64-bit) is no longer available. I see gcc-7 and gcc-9. But no gcc-8. If it has been removed, is it perhaps still possible to find it for Tumbleweed?

gcc versions for tumbleweed are normally removed once nothing in the distro still really needs it for building. I guess we have settled on gcc-7 for anything that needs an older gcc, and still have gcc-9 because certain things havent finished migrating from 9 to 10 yet. -- Simon Lees (Simotek) http://simotek.net Emergency Update Team keybase.io/simotek SUSE Linux Adelaide Australia, UTC+10:30 GPG Fingerprint: 5B87 DB9D 88DC F606 E489 CEC5 0922 C246 02F0 014B

I did a search on openSUSE downloads, and it only had some Debian release. Nothing for openSUSE.

I tried other GCC releases witn NVCC, but it complains that they are unsupported versions. It wants gcc-8.

gcc8 seems to still be available in devel:gcc

There is no Tumbleweed version.

I have tried installing both the Factory and the Leap 15.1 version. In both cases the install wants to remove some library used by another gcc version. I do not want to do this. That sounds like a recipe for disaster. I still need the other gcc versions.

I think it is accurate to say that there is no functioning gcc-8 on OBS for Tumbleweed.

To be more specific. I get this when trying to install gcc-8 from devel:gcc on Tumbleweed: gcc8-8.4.0+git2127-lp152.1.1.x86_64 requires libmpx2 >= 8.4.0+git2127-lp152.1.1, but this requirement cannot be provided not installable providers: libmpx2-8.4.0+git2127-lp152.1.1.x86_64[openSUSE_Leap_15.1] [ ] Following actions will be done: deinstallation of libmpx2-gcc7-7.4.1+r275405-1.2.x86_64 deinstallation of libmpxwrappers2-gcc7-7.4.1+r275405-1.2.x86_64 [ ] do not install gcc8-8.4.0+git2127-lp152.1.1.x86_64 [ ] break gcc8-8.4.0+git2127-lp152.1.1.x86_64 by ignoring some of its dependencies Not sure what to do. The default gcc on the system of interest is 9.2.1. So maybe removing gcc-7 is not an issue.

I simply commented out the GCC version check in the NVIDIA CUDA headers and had no issues with GCC 9 so far, but I only needed it for OptiX.

I will try that. It would make life easier... I will report back when I have had a chance to test it. The machines in question are being used in production. We are doing feature detection on 30000 km of images, with 8 images taken each 10 meters (e.g. 24,000,000 images). We will do this for the next 5 summers. And it's not even the biggest part of the task. So I don't want to mess with the pipeline of processing! I will have to sneak in my test. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
