On this page: https://www.openoffice.org/porting/index.html there is a reference to "a port to OpenSolaris (Sparc) by Adfinis SyGroup AG (Nicolas Christener)":
http://adfinis-sygroup.ch/aoo-solaris-sparc/ But that page is 404 and should probably be removed (unless anyone knows where it went). Same for this link directly below that one: http://www.opensolaris.org/ I think I'm going to try building 4.1.7 in Solaris 11.4 SPARC myself. - Michele
