libssh2 on CodeLite

[Blai]

Hi,

I'm pretty new to CodeLite and programming in general.

I installed CodeLite on a Windows 10 machine. Made a sample console program, working.

Now I would like to create a C program that uses libssh2 library (https://www.libssh2.org/) to connect to a Linux box and execute some commands.

I wanted to use this file:

https://www.libssh2.org/examples/ssh2_exec.html

so I imported the files inside the src and include directories of libssh2 into my project.

Unfortunately, the program crashes on building with several errors like:

Code: Select all

Any help would be appreciated on how to use this library on my project

Thanks in advance

You don't need to import them. You need to let the compiler the location of the headers of this library + where it can find the library itself during link
You should download a prebuilt binary and use that
