# Install GCC 14
sudo apt update
sudo apt install gcc-14 g++-14 gfortran-14
# Set as default
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-14 60
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-14 60
sudo update-alternatives --config gcc
sudo update-alternatives --config g++Ubuntu 22.04 (Build GCC 14 from source)
# Install dependencies
sudo apt install build-essential libmpfr-dev libgmp3-dev libmpc-dev -y
# Download and build GCC
wget http://ftp.gnu.org/gnu/gcc/gcc-14.1.0/gcc-14.1.0.tar.gz
tar -xf gcc-14.1.0.tar.gz
cd gcc-14.1.0
# Configure and build (1-2 hours)
./configure --prefix=/usr/local/gcc-14.1.0 --enable-languages=c,c++ --disable-multilib
make -j$(nproc)
sudo make install
# Set up alternatives
sudo update-alternatives --install /usr/bin/gcc gcc /usr/local/gcc-14.1.0/bin/gcc 14
sudo update-alternatives --install /usr/bin/g++ g++ /usr/local/gcc-14.1.0/bin/g++ 14# Set up vcpkg (one-time setup)
git clone https://github.com/microsoft/vcpkg.git
cd vcpkg && ./bootstrap-vcpkg.sh -disableMetrics && cd ..
## If you want you can specify vcpkg locally without globally setting env variable (see -DCMAKE_TOOLCHAIN_FILE version)
export VCPKG_ROOT=/path/to/vcpkg # Add to ~/.bashrc
# Clone repository and submodules
git clone --recursive https://github.com/MrNeRF/LichtFeld-Studio
cd LichtFeld-Studio
# Build
cmake -B build -DCMAKE_BUILD_TYPE=Release -G Ninja
## Or if you want you can specify your own vcpkg
# cmake -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE="<path-to-vcpkg>/scripts/buildsystems/vcpkg.cmake" -G Ninja
cmake --build build -- -j$(nproc)
