Do you get the jobserver warning while running "make release" or "make
debug" with "-j8"?
If so - that's because you cannot recursively call into make with the
jobserver feature that way.
We have fixed the example steps a while ago but probably never updated
the documentation regarding these two custom targets. It is best to
simply have:
ADD_CUSTOM_TARGET(debug
COMMAND ${CMAKE_COMMAND} -DCMAKE_BUILD_TYPE=Debug ${CMAKE_SOURCE_DIR}
COMMENT "Switch CMAKE_BUILD_TYPE to Debug"
)
ADD_CUSTOM_TARGET(release
COMMAND ${CMAKE_COMMAND} -DCMAKE_BUILD_TYPE=Release ${CMAKE_SOURCE_DIR}
)
and then
$ make release
$ make -j8
or
$ make debug
$ make -j8
Best,
Matthias

My library does compile but falls back to make -j1 every time I invoke make -j8. My question is why? And how can I use all cores? Thank you and merry Christmas!

Re: [deal.II] Re: cmake with library and executables
Konrad,
your email has no question :-) Is your problem that you can't call 'make -j8'
and your question how to make that possible? If so, what happens if you try?
What is the error message?
Best
W.
