    With all those bug fixes it's clearly inferior software


    The joke is I'm making fun of people who make fun of KDE bug fixes

      But if you fix all KDE bugs, what is left of KDE?

          Really. 'Cuz I ran into a gcc-9 bug just last night on CentOS-7 devtoolset-9. (That machine is currently playing at Windows, so I can't check the exact gcc-9 minor version.) The code in question compiles just fine with gcc-8.5 (CentOS-8 Stream), 10.x (Whatever Fedora 32 used) and gcc-11 (Fedora-34), The code looks like a very simple template, pretty sure it's a gcc-9 bug and hope it's among those fixed.

            Did you file a bug report? Hoping isn't a very effective strategy.

              Notabug. Won't fix.

              I'm an unpaid volunteer maintainer. I cheerfully file bug reports against Fedora and CentOS-8 Stream. But against CentOS-7 I draw the line.

              I have no personal stake in CentOS-7. My only interest in CentOS-7 are my product's users. On CentOS-7 I specify scl devtoolset-8, which works Just Fine.

              At best scl devtoolset-9 just confuses the issue. At worst fixing any problems there might give someone somewhere an excuse to remain on that obsolete platform.

              The open-source product I help maintain is Ball Aerospace's Opticks GIS. It does multi-spectral stuff unavailable on any other open-source GIS. Opticks is Really Neat.

              We've recently picked up some Windows developers, who have introduced version creep of various components. CMake 2.8 no longer works for us. Fortunately CentOS-7 has a cmake3 (3.17.5) which does. Someone has also introduced an OpenCV dependency somewhat newer than the archaic version 2.4.5 CentOS-7. For that I must specify an OpenCV build from source. I don't need that.

              I'll do what I can for my CentOS-7 users, but I'd rather work with Windows10-Linux compatibility from a more modern platform.

              As for those who need gcc-9, CentOS-8 Stream's gcc-toolset-9 has gcc version 9.2.1-2, which also compiles Opticks Just Fine.

              The code compilation problem I see on CentOS-7 devtoolset-9 (gcc 9.1.1-2) is a bit more complicated than I'd originally supposed in my earlier comment. Distilling it down for Bugzilla would require time I simply do not have, for a problem that doesn't really exist.


              FWIW, tonight I checked that a bugzilla had been filed against gdal on CentOS-8 Stream (it won't install), and filed a new one against scl (it won't itself enable gcc-toolset-9).


              But thanks for asking. Always appreciate your -- and any vendor's -- participation in these threads.

                To be clear, I am not a vendor. If you are hoping for bugs to be fixed, you have a vested interest in seeing them get fixed and bug reports would be a more effective approach than forum posts but whatever floats your boat.
