Unfortunately that's the latest choice I have through the Raspbian distro. I could try older GCCs at least probably as there's gcc 4.4-4.9 and 5 packages.
EDIT: Installing gcc-4.9 and editing src/makefile to point to that allowed it to successfully compile and run
By the way, if I would like to have PCem's executable for Raspbian or the OS you tested it... is there any official v15 release? Because I don't see any for download
I've compiled from the windows release's sources. I don't like sharing binaries and I recommend compiling it yourself (apart from that gcc version fumble... it's easy!!!)
Also i'm expecting the RPI4 to do 486DX40. Being VERY optimistic here... hopefully the VCVI's driver doesn't bottleneck as hard.
I would add to the request to make a PCEm release for Raspbian publically available as an official release. For me PS/2 hardware is aging and a fully solid state substitute (Pi) would be fantastic (even if speed limited to 486/25). For those of us who know DOS thoroughly but have no experience with Linux/Raspbian, someone doing a step by step "up and running" tutorial would also be great.
I didn't have any major trouble to compile PCem, the worst part was to build wxWidgets, it took a lot of time because I had to use a single thread to keep the my Pi cool.
That's because I'm using a Pi 3 B+ with the official touchscreen and its corresponding case without active cooling, using all cores to compile anything rises the temperature over 70 ºC in a few minutes.
I copied a working machine with Windows ME installed from my PC and it seems to run at 100% emulating a Pentium 75, but that's while idling otherwise it falls to 15~20%
