在openSUSE-Leap-15.6-DVD-x86_64中使用gnome-builder-45.0的基本功能（三）空白Meson工程

news 2026/5/12 18:16:14

需要安装meson、ninja、cmake、flatpak还有SDK
应用程序——工具——终端
ruhongvnc@localhost:~> su -
密码：
localhost:~ # zypper install meson ninja cmake flatpak
localhost:~ # flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
localhost:~ # flatpak remote-modify flathub --url=https://mirror.sjtu.edu.cn/flathub
参考上海交通大学软件源镜像服务https://mirrors.sjtug.sjtu.edu.cn/docs/flathub
使用flathub.org网站下载是非常缓慢的，改成使用mirror.sjtu.edu.cn/flathub就非常快速了
ruhongvnc@localhost:~> flatpak remotes --show-details

ruhongvnc@localhost:~> cat /var/lib/flatpak/repo/config
localhost:~ # flatpak list|grep gnome
GNOME Application Platform version 45 org.gnome.Platform 45 system
localhost:~ # gnome-builder --version
GNOME Builder 45.0
系统安装gnome-builder-45就会自动安装对应版本的org.gnome.Platform 45

localhost:~ # flatpak search org.freedesktop |grep -i org.freedesktop.sdk
搜索有什么SDK可以安装
localhost:~ # flatpak install org.freedesktop.Sdk
安装org.freedesktop.Sdk，其中S要大写

应用程序——编程——构建器——最下方创建新工程——工程名称multiplication_table_meson——应用程序ID:org.example.multiplication_table_meson——模板——空白Meson工程——创建工程
打开src/main.c把它换成以下打印乘法口决multiplication_table的C程序，组合键Ctrl＋S保存
ruhongvnc@localhost:~> cat /home/ruhongvnc/工程/multiplication_table_meson/src/main.c

#include"config.h"#include<stdio.h>#include<glib.h>#include<stdlib.h>gintmain(gint argc,gchar*argv[]){inti,j;g_autoptr(GOptionContext)context=NULL;g_autoptr(GError)error=NULL;gboolean version=FALSE;GOptionEntry main_entries[]={{"version",0,0,G_OPTION_ARG_NONE,&version,"Show program version"},{NULL}};context=g_option_context_new("- my command line tool");g_option_context_add_main_entries(context,main_entries,NULL);if(!g_option_context_parse(context,&argc,&argv,&error)){g_printerr("%s\n",error->message);returnEXIT_FAILURE;}if(version){g_printerr("%s\n",PACKAGE_VERSION);returnEXIT_SUCCESS;}printf("9x9 乘法口诀表:\n");for(i=1;i<=9;i++){for(j=1;j<=i;j++){printf("%d*%d=%d\t",j,i,i*j);}printf("\n");// 每打印完一行后换行}returnEXIT_SUCCESS;}

提示安装org.freedesktop.Platform/x86_64/22.08——取消
单击最上方铁锤图标旁边的倒三角图标——配置工程——配置——org.example.multiplication_table_meson——位置——源码树内部——运行时——org.freedesktop.Platform/x86_64/25.08，其实就是修改org.example.multiplication_table_meson.json文件
右上角三根横线——首选项——左下角SDKs——可用SDK
默认或者源码树外部，编译出执行文件存放的路径是
/home/ruhongvnc/.cache/gnome-builder/projects/multiplication_table_meson/builds/org.example.multiplication_table_meson.json-flatpak-org.freedesktop.Platform-25.08-x86_64-main/src/multiplication_table_meson

源码树内部，编译出执行文件存放的路径是
/home/ruhongvnc/工程/multiplication_table_meson/_build/src/multiplication_table_meson

单击最上方铁锤图标，编译程序multiplication_table_meson
单击最上方第二个三角图标，运行程序multiplication_table_meson打印乘法口决表

单击最上方第三个三角图标——选择运行命令——运行命令——自动发现或者multiplication_table_meson
单击最上方铁锤图标旁边的倒三角图标——清理
单击最上方铁锤图标旁边的倒三角图标——重新构建

删除SDK文件的命令
localhost:~ # flatpak uninstall --unused
或者
localhost:~ # flatpak uninstall org.freedesktop.Sdk
