Do u fix it ? Because i have the same problem

[aehlke]

Likewise, any luck?

[bemehiser]

This is likely caused by compiling with headers from one libssh2 version, then linking a different one. I saw similar errors when my libraries were compiling with headers from Conan, then linking libraries installed by brew.

To solve this, I removed the brew-installed version.
