问题描述
这里指出找不到软件包 gtk+-3.0：
karl@karl-ux303ln:~$ pkg-config --cflags gtk+-3.0
Package gtk+-3.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-3.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-3.0' found
但是我显然已经安装了 gtk3：
karl@karl-ux303ln:~$ dpkg -l libgtk* | grep -e '^i' | grep -e 'libgtk-*[0-9]'
ii libgtk-3-0:amd64 3.14.15-0ubuntu1~14.04~ricotz1 amd64 GTK+ graphical user interface library
ii libgtk-3-bin 3.14.15-0ubuntu1~14.04~ricotz1 amd64 programs for the GTK+ graphical user interface library
ii libgtk-3-common 3.14.15-0ubuntu1~14.04~ricotz1 all common files for the GTK+ graphical user interface library
ii libgtk2.0-0:amd64 2.24.23-0ubuntu1.3 amd64 GTK+ graphical user interface library
ii libgtk2.0-bin 2.24.23-0ubuntu1.3 amd64 programs for the GTK+ graphical user interface library
ii libgtk2.0-common 2.24.23-0ubuntu1.3 all common files for the GTK+ graphical user interface library
但是我似乎找不到文件 gtk+-3.0.pc ：
karl@karl-ux303ln:~$ sudo find / -name "gtk+-3.0.pc"
karl@karl-ux303ln:~$
有任何想法吗？我正在尝试使用 cmake 但它找不到 gtk3。
最佳回答
我只安装了普通的 gtk3 文件，没有安装 cmake 使用所需的开发文件：
sudo apt-get install build-essential libgtk-3-dev
