On with my various experiments with the FreeBSD amd64 migration today. The biggest discovery was how to find 32 bit shared libraries. I had already discovered that ldconfig ignores files with specific names, but that appears to be a bug in ldconfig. In any case, using the old (probably deprecated ) environment variable LD_32_LIBRARY_PATH works, so now I can run all my old 32 bit programs like kklondike and my version of xearth.
More importantly, though, I can run the 32 bit versions of the Hugin programs. Did a lot of experimentation, including running hugin-i386. That worked, but it wasn't able to load the fonts:
Still, detecting the control points with panomatic-i386 was successful, and the panorama looked OK. Saved the project, started 64 bit Hugin with the same parameters, and it still looked OK. Ran Align again, using 64 bit panomatic, and it broke it again. Somehow I'm not getting much further. Saved the project files for 32 bit and 64 bit detection for further reference. They're very different, but nothing reaches out and grabs me.
On the positive side, took some time to get the web server and mail running. And once again I had lots of changes to make in my PHP code because they don't want POSIX regular expressions any more. By comparison, getting mail up and running was easy.
