I've been working on a project for embedded system and it needs SSL/TLS functionality.

I downloaded SSL project from GitHub (WolfSSL to be specific), compiled it with autotools, then created a static library libwolfssl.a using ar from libtools which archived all the .o files

I need to use the functions implemented in WolfSSL in my code, for example SSL_Library_Init()

How can I add the static library and use the functions using Eclipse IDE ?

I tried the following:

Added library path to the C linker -L: ${workspace_loc:/${ProjName}/lib}
Added library name to -l : wolfssl where the library name is libwolfssl.a
When I try to build the project, anything related to SSL is not recognized yet, ex: SSL_Library_Init and so on
Is this the correct way to do this?

It's probably best to ask about C/C++ related things on the CDT forum.

I don't know how to do that. Reposting is okay.
