【问题描述】：

我正在关注https://wiki.wxwidgets.org/Compiling_and_getting_started wxWidgets 的安装指南。

当我安装先决条件时出现错误：

命令：

sudo apt install libgtk2.0-dev

错误：

The following packages have unmet dependencies:
 libgtk2.0-dev : Depends: libglib2.0-dev (>= 2.27.3) but it is not going to be installed
                 Depends: libgdk-pixbuf2.0-dev (>= 2.21.0) but it is not going to be installed
                 Depends: libpango1.0-dev (>= 1.20) but it is not going to be installed
                 Depends: libatk1.0-dev (>= 1.29.2) but it is not going to be installed
                 Depends: libcairo2-dev (>= 1.6.4-6.1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

【问题讨论】：

为什么不安装libwxgtk？这将引入所有依赖项...
如果以sudo apt install build-essential开头会怎样？
@lgor 我试过它显示pradeep@7:~/wx/wxWidgets-3.0.5/gtk-build$ sudo apt-get install libwxgtk [sudo] password for pradeep: Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package libwxgtk
@Ripi2 我也尝试过使用该命令pradeep@7:~/wx/wxWidgets-3.0.5/gtk-build$ sudo apt install build-essential [sudo] password for pradeep: Reading package lists... Done Building dependency tree Reading state information... Done build-essential is already the newest version (12.8ubuntu1). 0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.
@sutharp777，您使用的是哪个操作系统？看起来您使用的是 Linux (Ubuntu)，但错误表明您使用的是 Windows。那么是哪一个呢？你也可以使用包名libwxGTK、libwx、libWX。或者，如果您正在使用 GNOME - 只需配置和编译。

【解决方案1】：

运行

sudo apt-cache search libwxgt*

它输出一些包名。而不是尝试一个一个地安装所有的包。

输出

libwxgtk-media3.0-gtk3-0v5 - wxWidgets Cross-platform C++ GUI toolkit (GTK 3 media library runtime)
libwxgtk-media3.0-gtk3-dev - wxWidgets Cross-platform C++ GUI toolkit (GTK 3 media library development)
libwxgtk-webview3.0-gtk3-0v5 - wxWidgets Cross-platform C++ GUI toolkit (GTK 3 webview library runtime)
libwxgtk-webview3.0-gtk3-dev - wxWidgets Cross-platform C++ GUI toolkit (GTK 3 webview library development)
libwxgtk3.0-gtk3-0v5 - wxWidgets Cross-platform C++ GUI toolkit (GTK 3 runtime)
libwxgtk3.0-gtk3-dev - wxWidgets Cross-platform C++ GUI toolkit (GTK 3 development)

例如

sudo apt-get install libwxgtk-media3.0-gtk3-0v5
...

等等。
