Did you link both with cairo-gtk and cairo?

Pro-pra commented 2 years ago

I don't know

Chris00 commented 2 years ago

Is the above error displayed when you build cairo? Using OPAM? From source?

Looks like it is build from RPM. Do other libraries install fine? The error (2nd line)

point to the fact that OCaml runtime is not present. Did you get it touch with the RPM packager?

i see in /usr/lib64/ocaml:
