Native support for the latest tools and frameworks , Such as Qt5 、 Code coverage 、 Unit testing and precompiled header files, etc . Use a set of optimization techniques to quickly mutate code , Including incremental compilation and full compilation .

2. install meson

   Be careful ：meson Before installation, you must confirm whether it has been installed python3.5 And above ; because meson Depend on python3 and ninja

   2.1 install python3 and ninja： sudo apt-get install python3 python3-pip ninja-build

Check again python edition

python -V
Version prompt is 3.6.x

2.3 install meson：pip3 install --user meson

echo ‘export PATH=/home/jack/.local/bin:$PATH’ >>~/.bashrc

$proxychains4 -q git clone https://gitlab.freedesktop.org/libfprint/libfprint.git
$cd libfprint
$meson build -D gtk-examples=false # precompile , There may be errors , You should ensure that the following components have been installed ：gcc、pkg-config、glib-2.0、gio-unix-2.0、gusb、cairo、pixman-1、nss、udev、gdb、valgrind
$ninja -C build # There will be something about /usr/include/stdlib.h The error of , I ignored , continue installation
$sudo meson install -C build # install
