The KB doesn't mention that debug symbol RPMs may only be available on some, but not all, currently supported RPM platforms, it implies that they are available everywhere:

Based on what we did on the CentOS 7 builders, to fix this we would need to update cmake on our CentOS 6 builders to something above 3.8. Only 3.6.x is available in the epel repos so we would need to compile it from source. serg and elenst: Any objections from either of you?

I have no preferences for this, one way or another. CentOS 6 finally goes EOL in half a year, but if the debug packages are really needed, my understanding from previous similar discussions is that using higher versions of cmake is supposed to be harmless.

Actually, cmake on our CentOS 6 builder is already at version 3.9.6 from an upgrade we did to its toolchain back in March for our bintar builds. So I just need to find out why it is not making the debuginfo packages....

In a recent compile log I see several of these warnings for various components (backup, server, connect, rocksdb, etc...):

CPackRPM:Debug: CPACK_RPM_DEBUGINFO_EXCLUDE_DIRS= /usr;/usr/src;/usr/src/debug

CMake Warning (dev) at /usr/local/share/cmake-3.9/Modules/CPackRPM.cmake:2279 (message):

  CPackRPM:Warning: debuginfo package was requested but will not be generated

  as no source files were found! Component: 'server'.

Call Stack (most recent call first):

  /usr/local/share/cmake-3.9/Modules/CPackRPM.cmake:2745 (cpack_rpm_generate_package)

  /home/buildbot/buildbot/padding_for_CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX/mariadb-10.2.32/cmake/Internal/CPack/CPackRPM.cmake:56 (include)

This warning is for project developers.  Use -Wno-dev to suppress it.

So it appears cmake is at least acknowledging that it was supposed to make various debuginfo packages, but it's not finding the source files it needs to be able to do so. I'm not sure why this is happening as I don't know cmake well enough. serg: Any ideas?

We no longer build CentOS6 RPM packages
