I'll post up binaries for the ALPHA test release of LisaEm 1.2.7 in the next 2-3 days, slightly earlier than I'd like, but due to Catalina, I need to publish at least x86_64 at Catalina kills off 32 bit executables. For this, I'm using an older ~2009 10.9.5 macbook, as I don't readily have anything older that currently works and supports 64 bit x86 binaries, so that would be the cutoff for x86_64 at least for the immediate future - that won't stop you from compiling it yourself.
I'm trying to get wxWidgets built for 64 bit mode PowerPC on macos x 10.5.8, but I'm running into various errors. (Not sure if 10.4 will support 64 bit binaries).
So, I'm wondering does anyone still care about PowerPC support on OS X? If so is 64 bit desirable or is 32 bit sufficient?
[ If you're curious, github has 1.2.7 that I've pushed out ~ Friday night, which works on Linux - at least Ubuntu 18.04.x, but does not have the proper build scripts for os x which I've been hacking on over the weekend. I'll push the changes out when I publish the DMGs. ]
