Hello!
Choosing a custom installation directory for the documentation is not supported with the current 'configure' script. I recreated it using autoconf 2.69 and then noticed the following issues:
$(am__check_pre) $(LOG_DRIVER) is expanded. The fix is to remove the trailing $(SHELL) at the end of the the TEST_ENVIRONMENT variable definition in tests/Makefile.am.docdir = @docdir@
Thanks,
Maxim
This shows up as an OpenJade bug, but it is meant for OpenSP.
