我在尝试使用Qt5.7构建gst-plugins-bad时遇到此错误:
Package Qt5Core was not found in the pkg-config search path.
Perhaps you should add the directory containing `Qt5Core.pc'
to the PKG_CONFIG_PATH environment variable
在Qt 5.5中,曾经有一个~/Qt/5.5/clang_64/lib/pkgconfig/Qt5Core.pc
文件。但是,Qt5.7安装我在Qt5OpenGLExtensions.pc
内只有Qt5UiTools.pc
和~/Qt/5.7/clang_64/lib/pkgconfig
。所有的pkg-configs都去了哪里?
