db48 @4.8.30: fails to build +java

[OrbitalMechanic (Samuel Dupree)]

Building Octave on Mac Pro (2019) under Mac OS X v. 10.15.3 (Catalina). Followed procedure posted on ​https://wiki.octave.org/Octave_for_macOS#MacPorts_Installation and ​http://blog.hani-ibrahim.de/en/octave4-mac-os-x-el-capitan-install.html. The installation failed to configure db48.

Logfile attached to this ticket.

looks like the +java variant of db48 is not working, at least on Catalina.

I'd suggest you go with the default installation, at least to begin.

sudo port clean db48
sudo port clean octave
sudo port -v install octave

The article about installing octave you referenced was about four years old, and things can change over time...Marcus sets the defaults quite carefully, and you should find them OK.

If you really need java support in Octave, it may still be possible to use that variant later, after all it's supports are installed.

normally it's best to also include the main log file from your failed installation as well, to help us understand what is going on.

I notice there are already two open tickets about db48 failing to build +java, so no reason to open a third one it appears; this is not unique to Catalina. <​https://ports.macports.org/port/db48/tickets>.
