It should be possible to build openoffice in a *-solaris prefix. I will attempt to do so and attach patches for errors as I encounter them. Reproducible: Didn't try Steps to Reproduce:
Created attachment 193009 [details, diff] ooo-build-sfw-b-gone.patch remove /usr/sfw from bin/build-ooo
are this all patches necessary, or did the rather optimistic attempt to compile openoffice silently fail?
I started to work on it, but got soon exhausted. Presently it does not compile, much less work.
