Project Management

• Create Project:

# ==== Install cemu ==== #
wget https://xmake.io/shget.text -O - | bash
git submodule update --init --recursive

# ==== Install xmake ==== #
# zsh <(wget https://xmake.io/shget.text -O -)
# bash <(wget https://xmake.io/shget.text -O -)
source ~/.xmake/profile
xmake --help
xmake update
# xmake update --uninstall
xmake create uemu & cd uemu

• Compile Project:

# ==== Local Compile ==== #
xmake f -a x86_64 --toolchain=gcc                      # config
xmake -v                                               # compile

xmake c -a                                             # clean all
# xmake install -o [dir]                               # install

# ==== Cross Compile ==== #
xmake f -a aarch64 -p linux --cross=aarch64-linux-gnu-
xmake -v
# xmake r
qemu-aarch64 ./build/linux/aarch64/release/uemu        # emulate
