Re: How to Link static

[Cristian Saavedra <cristianpsg@xxxxxxxxx>]

Hi Petar,

Thanks for your help.
You are right -L is for directories.

At the end I was able to build static with
g++ -o ssh ssh.cpp /usr/lib64/libssh.a -lssl -lrt

The -static flag was giving me a lot of missing libraries.




Best Regards,
Cristian Saavedra
