Building Musescore 2.0 on Fedora 21
I built Musescore 2.0 on Fedora 21 as no .rpm were available as of yet. I contacted the Fedora package maintainers again and hope they will build .rpm soon. If not, I will build some .rpm , but am sort of waiting for Fedora 22 at the moment.
FWIW it is a moderately large build ;)
For those interested in building, the only compile errors I received were due to missing dependencies. The compile errors are a bit cryptic so you may need to identify and install the dependencies manually if I missed one.
To build on Fedora 21 ;)
Download and extract the .zip file from https://musescore.org/en/download#Source-code , extract the archive.
Install the dependencies
sudo yum install -y gcc gcc-c++ qt-devel pulseaudio-libs-devel alsa-lib-devel jack-audio-connection-kit-devel qt5-qtbase-devel qt5-qttools-libs-designercomponents qt5-qttools-devel portaudio-devel poppler-qt5-devel
qt5-qtdeclarative-devel qt5-qtscript-devel qtermwidget-qt5-devel qt5-qtwebkit-devel qt5-qtxmlpatterns-devel qt5-qtquick1-devel qt5-qtsvg-devel qt5-qttools-devel qt5-qttools-static lame-devel libsndfile-devel
sudo make install
So far working without obvious problems. I use standard and tab notation piano, guitar, mandolin, and mandolin
If you use an alternate distro, check your distro for similar packages.
FWIW it installs into /usr/local by default ;)
