问题描述

我正在尝试从这个 教程 Ubuntu 上使用 gcc.我必须使用什么作为 gcc 的参数来包含 #include <libappindicator/app-indicator.h> 所需的库?

I am trying to compile the simple C example from this Tutorial on Ubuntu using gcc. What do I have to use as argument for gcc to include the needed libraries for #include <libappindicator/app-indicator.h>?

推荐答案

如果你使用了apt-get、Synaptic Package Manager 等来获取appindicator 库(相对于从源代码构建)，您是只安装了 libappindicator1 包还是还安装了 libappindicator-dev 获取libappindicator 头文件?Linux 包经常将运行时库与编译时头文件分开.这样，只需要库来满足动态链接的人就不必安装不需要的头文件.但是由于您正在进行开发，因此您需要这些头文件，因此也需要 libappindicator-dev 包.

If you used apt-get, Synaptic Package Manager, etc. to get the appindicator library (vs. building it from source), did you only install the libappindicator1 package or did you also install libappindicator-dev to get the libappindicator header files? Linux packages very often have split the runtime libraries from the compile-time headers. That way people who only need the libraries to satisfy a dynamic link don't have to install unneeded headers. But since you're doing development you need those headers and therefore need the libappindicator-dev package as well.
