Question

在Ubuntu中下载并安装软件包后，如何查看库和头文件的写入位置？我相信这与包的.pc文件有关，但我不知道如何找到该文件。

例如，我已经下载了PCL（Point Cloud Library）软件包，然后在示例CMakeLists.txt文件中，我获得了以下内容：

include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})

这些环境变量在哪里定义，我怎样才能看到它们？

如果我从源代码而不是通过软件包编译库，这会有什么不同吗？是否会自动创建.pc文件？

Answer 1

如果安装包含libpcl开发文件的包

sudo apt-get install libpcl-dev

您可以列出已安装的文件

dpkg -L libpcl-dev

查看所有标题的位置。

默认情况下，库安装在/ usr / lib中，头文件位于/ usr / include

中

通常，库文件的扩展名为.so，相应的头文件为.h

用于查找已安装库的gui方法是开放软件中心 - ＆gt;开发人员工具 - ＆gt;库

安装包库和头文件在哪里？
