Can mod_auth_openidc run on solaris11 systems?

[2168028160]

We encountered the following problem when installing mod_auth_openidc on a solaris 11.4 system.
If solaris is supported, how should I solve the following problems. Thanks.

1. with make.
   make: Fatal error in reader: Makefile, line 18: Unexpected end of line seen

2. with gmake.

Solaris is only supported under a commercial support subscription

Is it possible to provide a trial version of solaris11.3?
