dvdbackup/main.log

[ryandesign (Ryan Carsten Schmidt)]

This port has no MacPorts maintainer. We already have the latest version of dvdbackup in MacPorts. You may want to ​report the problem to the developers of dvdbackup so that they can fix it.

[ryandesign (Ryan Carsten Schmidt)]

We were able to build dvdbackup on 10.15 and earlier on our build machines one year ago. Maybe something changed with the file /opt/local/include/dvdread/ifo_types.h since then. It is provided by the port libdvdread, and I see that libdvdread was updated to 6.1.1 last week. Perhaps this version of dvdbackup is not compatible with this new version of libdvdread.

[ryandesign (Ryan Carsten Schmidt)]

We do ​see the same problem when trying to build the port now on macOS 11 arm64, so the problem is not unique to your system.

[ryandesign (Ryan Carsten Schmidt)]

In fact it ​has already been reported to the developers and there is a patch there that is said to work.

[ryandesign (Ryan Carsten Schmidt)]

In dcb83a11bb8ef17668e9de650960ef1b15a6e468/macports-ports (master):

dvdbackup: Fix build with libdvdread 6.1.0+

Increase revision to rebuild with libdvdread 6.1.0.

Closes: #62221
