第133页的gtk+编程例子——计算器应用练习从源代码编译gnome-calculator-45.0.2
以前在linux编译安装软件的步骤是
./configure
make
make install
make uninstall
如今就是
mkdir buildxxxxxxxx
meson setup buildxxxxxxxx
cd buildxxxxxxxx
ninja
ninja install
ninja uninstall
如今也很少有软件是让用户从源代码编译，直接提供rpm和deb格式包下载，同时提供repo文件下载让你使用dnf或者apt能够实时更新下载并解决依赖关系
在openSUSE-Leap-15.6-DVD-x86_64的gnome41.8桌面环境，它已经自带有gnome-calculator版本为45.0.2
应用程序——工具——终端
ruhong@localhost:~>
ruhong@localhost:~> gnome-calculator --version
gnome-calculator 45.0.2
ruhong@localhost:~> which gnome-calculator
/usr/bin/gnome-calculator
应用程序——互联网——firefox——打开https://gitlab.gnome.org/GNOME/gnome-calculator
网页左边——单击main——gnome-45protected——网页右边——单击Code——tar.gz——下载gnome-calculator-gnome-45.tar.gz，大小为2.4MB
应用程序——工具——终端

这一步类似./configure，它会报错系统缺少meson，就使用zypper search meson搜索一下，再使用zypper install meson补安装一下，再次运行meson setup build20260120/，再报错缺少，再补安装，直到没有报错为止

这一步类似make

这一步类似make install，安装到系统中
localhost:~/gnome-calculator-gnome-45/build20260120 # which gnome-calculator
/usr/local/bin/gnome-calculator
localhost:~/gnome-calculator-gnome-45/build20260120 # ls -lh /usr/local/bin/gnome-calculator

localhost:~/gnome-calculator-gnome-45/build20260120 # /usr/local/bin/gnome-calculator
是能够成功运行的，默认安装在/usr/local/bin/，而系统自带的就在/usr/bin
localhost:~/gnome-calculator-gnome-45/build20260120 # ls -lh /usr/bin/gnome-calculator
-rwxr-xr-x 1 root root 735K May 9 2024 /usr/bin/gnome-calculator
