I’m trying to build this from source on my Cortex ARM A7. Most things compile quite happily on that platform, yet I’m having a problem with libssp.
If I run gcc -v I get:
Using built-in specs.

which includes the line --enable-libssp.
So when I type make for ZeroTier I get:

collect2: error: ld returned 1 exit status

Which suggests that libssp isn’t available. Can anyone help?
Thanks,
