I did an strace and found the following:
4989 access("/gnu/store/kwx5xihpxmjjf8f8446vn883ank1qcg1-qtbase-5.14.2/lib",
F_OK) = 0
4989
access("/gnu/store/kwx5xihpxmjjf8f8446vn883ank1qcg1-qtbase-5.14.2/lib/qt5/libexec/QtWebEngineProcess",
F_OK) = -1 ENOENT (Datei oder Verzeichnis nicht gefunden)
4989
access("/gnu/store/sd278fsdfx5hjrcgncflnp9qq4l42p1c-python2-2.7.17/bin/QtWebEngineProcess",
F_OK) = -1 ENOENT (Datei oder Verzeichnis nicht gefunden)
4989 write(2, "Could not find QtWebEngineProces"..., 34) = 34
This is a problem with a non-monolithic qt package: The file it is
looking for resides in qtwebengine, not qtbase.
The following works:
QTWEBENGINEPROCESS_PATH=`guix build
qtwebengine`/lib/qt5/libexec/QtWebEngineProcess ebook-viewer
Do we need to set a search path in qtwebengine?
