尝试从源代码在Ubuntu 20.04上构建Audacity v2.4.2 。

按照http://wiki.audacityteam.org/wiki/Building_On_Linux的说明

到目前为止我所做的：

  • 安装所有依赖项
  • 使用 gtk2 克隆和构建 wxwidgets 3.1.3
  • 使用示例测试 wxwidget - 最小和小部件（都很好）
$ /opt/newbie_2021/wxWidgets/buildgtk/samples/widgets/widgets

wxwidget 示例：小部件 UI

  • wx 配置输出：
newbie_2021@msig7-ubuntu:~$ wx-config --version
3.1.3
newbie_2021@msig7-ubuntu:~$ wx-config --list

    Default config is gtk2-unicode-3.1

  Default config will be used for output
  • 克隆的大胆

问题：

当我跑步时——

cmake -DCMAKE_BUILD_TYPE=Release -Daudacity_use_ffmpeg=loaded ..

我得到这个输出：

newbie_2021@msig7-ubuntu:/opt/newbie_2021/audacity/build$ cmake -DCMAKE_BUILD_TYPE=Release -Daudacity_use_ffmpeg=loaded --log-level=TRACE ..

更新 1：感谢#audacity 上的@Naglfar 帮助我解决这个问题。

我可以看到的第一个问题是“在 Linux 上构建”文档缺少makewxwidgets 构建命令。

其次，我必须明确指定目标位置： ../configure --with-cxx=14 --with-gtk=2 **--prefix=/usr/local**

我仍然遇到同样的错误，cmake但至少有一些进展。

newbie_2021@msig7-ubuntu:~$ find /usr/local/ -name version.h
/usr/local/lib/wx/version.h

更新 2：

终于解决了。我不得不删除 cmake 缓存文件。 CMakeCache.txt

之后cmake运行良好，make和make install.
