Kompilacja ikon blucurve na nowej fedorze 44

 sudo dnf install cmake python3 gtk2-devel gtk3-devel gtk4-devel gcc gcc-c++

git clone https://github.com/neeeeow/Bluecurve.git

cd Bluecurve
mkdir build && cd build
cmake ..       # jeżeli cmake wypluje błąd (cmake .. -DCOMPILE_GTK2_ENGINE=OFF)
make
sudo make install

 

Szybszy dnf na Fedorze

 sudo dnf config-manager setopt max_parallel_downloads=10 fastestmirror=True

 

Sprawdzenie  

dnf --dump-main-config | grep -E '^(fastestmirror|max_parallel_downloads) = ' 

 

 Reset do wartości domyślnych

sudo dnf config-manager unsetopt max_parallel_downloads fastestmirror
