I have "jobs: 4" enabled in my cabal config to get parallel installs with cabal-install >= 1.16.

When I do cabal install --reinstall --force-reinstalls world to reinstall all packages (e.g. to enable profiling or shared), it fails after some point, complaining that the required dependency package is not compiled with the needed flag (for profiling / -dyn).

It looks like for reinstalls, parallel cabal-install simply ignores the necessary order.

Can somebody confirm this or tell me if this is known? If not, where should it be reported?

As an off-the-cuff guess (not having had anything to do with developing cabal-install, etc.), it probably _does_ take dependencies into account... but it sees that the packages are all installed and thus order isn't sufficient. What it seemingly isn't taking into account is the new requirement to have profiling or dynamic builds of existing packages.

Thanks Niklas
