Dear all, today I attempted to migrate my stack towards 4.04.0 - unfortunately ppx_monadic is not yet available for that language version. I attempted to build it myself, but to no avail: Error: Required module `Compplugin' is unavailable This error is newly introduced into 4.04.0 (and does not exist in the HEAD version). Compplugin should be provided by compilerlibs.common, so I assume I need to fix the build system somehow. Does anyone have any idea how to fix this? regards, Christoph -- Christoph Höger Technische Universität Berlin Fakultät IV - Elektrotechnik und Informatik Übersetzerbau und Programmiersprachen Sekr.
