Hi Folks... I'm having some troubles with FFI in Fedora x86_64. I tried to execute some OS functions. I have all the libreries needed for that, but I always have the same error. In the *stack top *into FFICallbackThunk class when I send the allocateExcecutablePage message i got this: *#'insufficient C memory' * Has anyone had this kind of error before? This is the stack trace in my terminal.
