Compile on Linux with gcc-c++ 8.0.1

Post by mdhill »

I asked this question a couple of weeks ago but may have mislabelled it. My distro happens to be Fedora, but it's not necessarily distro-specific. The build fails (below) at std::set compare, as in this bug:

https://bugzilla.redhat.com/show_bug.cgi?id=1541688

Alternatively, is there an easy way to disable the compilation of the 3rdParty module where it errors out, or would that cause bigger problems?

Does it work to add the switch "BUILD_SMESH" in cmake and setting it to OFF or 0?

-DBUILD_SMESH=0 or _DBUILD_SMESH=OFF don't seem to have an effect. Is there another way to add a switch?

Thanks,

Mike

The latest version of gcc I see on the official website is 7.3. Are you using some kind of development build? What does "gcc --version" output in your terminal?

I'm living in the future with Fedora Rawhide. Building from git (and running) wasn't a problem until the gcc upgrade. Now I need to downgrade a number of packages to run my last good build, and przemof's latest Rawhide build is out of the question.

Code: Select all

$ gcc --version
gcc (GCC) 8.0.1 20180317 (Red Hat 8.0.1-0.19)

Hm. While I generally see no problem with wanting to run bleeding-edge software (I run gentoo, which typically means I'm running most of the latest stuff) for something as critical as GCC I'd stick to the latest release from upstream. v8.x appears to be something that is still in "trunk".

I realize you think your issues are non GCC related, but they very well could be.

On gentoo, we have a helper utility called "gcc-config" that allows us to have multiple versions of GCC installed and select which one to use. Do you have something similar on Fedora Rawhide? If so,can you switch to GCC 7.3 and see if the problem goes away?

I'll investigate the possibility. That would be ideal.

Meanwhile...

I deleted my build directory and started from scratch (as I did last week with no difference in the failure). This time I got a different error which yielded one Google hit:

https://forum.freecadweb.org/viewtopic.php?f=10&t=16229

From PrzemoF's cmake switches, I added '-DFREECAD_USE_EXTERNAL_SMESH=TRUE' and got to 60% before this failure:

Re: Compile on Linux with gcc-c++ 8.0.1

Hi Mike,
Older gcc works fine for you? I have gcc version 7.3.1 20180303 (Red Hat 7.3.1-5) (GCC) and I don't see the error.
