- Apply "reproducible-builds.patch", which makes GHC output
|
||||
deterministic by disabling multi-threaded compilation. Adding
|
||||
|
||||
Macros:
|
||||
# Enable multi-threaded builds in this project. This makes our
|
||||
# build products non-deterministic, e.g. not reproducible, but
|
||||
# we don't need them to be and would rather have fast results.
|
||||
%ghc_smp_mflags %{?_smp_mflags}
|
||||
:Macros
|
||||
|
||||
to an OBS project configuration re-enables multi-threaded builds,
|
||||
which might be useful for development projects that don't deliver
|
||||
binaries.

Subject: [PATCH] Compile with only 1 thread
|
||||
|
||||
but give an option to do fast non-deterministic builds
|
||||
|
||||
parallel compile causes assignment of random symbol names
|
||||
so we build single-threaded, which is slower, but gives reproducible results
