【问题描述】：
所以我试图在 linux 上编译 libssh2 库，但是当我尝试编译 例如，它出现了很多错误，即使我包含了它要求的头文件，它仍然要求它。 以下是错误消息和结果消息：
~/ gcc -include /home/Roosevelt/libssh2-1.2.5/src/libssh2_config.h -o lolbaise /home/Roosevelt/libssh2-1.2.5/example/scp.c

阅读消息。第一个说它找不到您包含的 libssh2_config.h 文件。如果你解决了这个问题，它很可能会解决所有其他问题。您可以通过阅读错误消息来学习很多东西，而不仅仅是举手询问其他人。
