I have a WP7700 running Legato 18.6.1, and a customized yocto build enabling sftp in curl.
To enable sftp I have added libssh2 to curls PACKAGECONFIG.
Previously I have been able to use sftp in libcurl after doing this, but it seems something has changed between 16.10.3 that is causing some issues.
Running curl -V tells me it is compiled with libssh2 and that it supports sftp, but curl_version_info(CURL_VERSION_NOW) tells me libssh_version is null and does not list sftp in its protocols.
I have been stuck on this for what feels like forever. Any ideas or suggestions would be greatly appreciated.
