Where did you get your sources from and how exactly did you try to build.
Hi,
so I guess from answers to your post that the problem we're facing is that core
devels build from some IDE, so the command-line is not used that often.
Hmm - that allmost sounds like you did run cmake in the toplevel source
directory. This, as you
have seen doesn't work since cmake does (at least with the default settings)
create a Makefile
(after all, that's the whole purpose of cmake) which would overwrite the
checked-in Makefile.
sure, I tried also the standard cmake workflow (that you mention below):
git clone
cd build.mine
cmake ..
make
but, unfortunately, the cmake ../ doesn't create any Makefile in the
build.mine/, so the last step 'make' can't do much :(.
However, I simply did what I did for any open-source software ever:
1) download sources or git clone
2) find some compile instructions in a README or COMPILE or similar
3) just follow them
As the instructions you find the easiest and quickest in 2) are the ones at:
https://musescore.org/en/developers-handbook/compilation/compile-instructions-linux-bsd-git
those tell you very precisely to:
1) git clone ...
2) cd MuseScore
3) make revision
I have a system-wide musescore, so I choose to follow up as:
4)make SUFFIX="-self" LABEL="Self Build"
5) sudo make SUFFIX="-self" LABEL="Self Build" install
I guess that as soon as pchs do work you'll see an incredible speedup during
compilation ;-)
yeah, I have some bare memory of that pch stuff when I was using Vistual Studio
back in another life..., don't know what's the status of pch with gcc et al.,
though.
Alternatively, instructions from the README need the sources tarball, but they
are along the lines of:
1) untar
2) cd untarred folder
3) make release
4) sudo make install
optional
5) cd build
6) make doxy
The instructions as reported above don't tell me to configure anything, nor
where to change configuration if any (tweak build folders, configuration flags,
debug vs non-debug version, optimization flags, whether to use pch or not, how
to specify Qt version as we're used to have at least Qt4 and Qt5 around,
whether to enable/disable optional features if any, etc....); they don't tell
me to build out of the sources dir, rather these instructions tell me to 'make'
from the root folder. Trying the standard cmake workflow simply fails.
Guess there should be revised instructions about the command-line compilation
workflow, I suspect the changes needed to the above steps are very minimal...
Thanks,
T.
