I don’t have permission to create an issue or PR on github, so I’m posting it here. The two PRs are: > **[Comparing apple:main...mavenraven:jemalloc-header-fix · apple/foundationdb](https://github.com/apple/foundationdb/compare/main...mavenraven:jemalloc-header-fix?expand=1)** > > FoundationDB - the open source, distributed, transactional key-value store - Comparing apple:main...mavenraven:jemalloc-header-fix · apple/foundationdb > **[Comparing apple:main...mavenraven:bumps-min-cmake · apple/foundationdb](https://github.com/apple/foundationdb/compare/main...mavenraven:foundationdb:bumps-min-cmake?expand=1)** > > FoundationDB - the open source, distributed, transactional key-value store - Comparing apple:main...mavenraven:bumps-min-cmake · apple/foundationdb The forum software only allows me to post 2 links, so I can’t directly link to the relevant issue on github (#7874). It’s interesting to me that CentOS build completes successfully since the logic in ConfigureCompiler.cmake suggests that it should have the same issue. Maybe `USE_SANITIZER` is true in that environment? There’s also a PR to fix the minimum cmake version. When I was trying to fix the jemalloc issue, I thought that it have been related to the version of cmake. None of the versions below 1.19 are able to generate a build anymore. ---

Thanks! I’ve created a PR with your cmake fix. Not sure if the cmake version fix is required. ---

The cmake one isn’t required, but foundationdb will no longer build with a cmake below 1.19. You can verify that by using [this](https://cmake.org/files/v3.18/cmake-3.18.0-Linux-x86_64.sh) script. Thanks for opening the PR! ---

Thanks! I checked our developer [Dockerfile](https://github.com/FoundationDB/fdb-build-support/blob/main/docker/centos7/Dockerfile), which uses 3.24.2. I’ve made a PR with your fix [Bumps minimum cmake required version. by jzhou77 · Pull Request #9438 · apple/foundationdb · GitHub](https://github.com/apple/foundationdb/pull/9438) of minimum cmake version. ---

Done! A sentence so that I meet the 20 character minimum of the forum software ---
