  • Ticket #27215 – Description

    v11 v13  
    1 The environment variable `SAGE_BUILD_TOOLCHAIN` has always been a bit of a hack. It is currently broken (probably due to #24919): imagine a system where the `gcc` Sage package is installed. If `mpir` is upgraded, then `mpir` is rebuilt (as dependency of `gcc`) with `SAGE_BUILD_TOOLCHAIN` but there is nothing forcing a second build of `mpir`.

If `mpir` is upgraded, then `mpir` is rebuilt (as dependency of `gcc`) with `SAGE_BUILD_TOOLCHAIN` but there is nothing forcing a second build of `mpir` without `SAGE_BUILD_TOOLCHAIN`.

    33Instead of trying to fix `SAGE_BUILD_TOOLCHAIN`, we just stop supporting it: toolchain packages are now built once just like any other package.
