Awesome I just re-built it, and yep the C compiler is running! Also you can vi bigger files, and whatnot, it’s overall so much more stable!

Now to copy over some ‘useful’ stuff like gzip, nethack, and f2c… !

yeah that /dev/ph0 is pretty frustrating. i can’t tell exactly where it hangs in the install. .modeminit doesn’t seem to hang, but attempting to run .phclr seems to hang when I run it on your hd.img. So .phclr may be the problem during the install process.

The fix for cc has been integrated into the gitbhub (https://github.com/philpem/freebee.git)

In reply to jesse. Yeah it’s probing for hardware that doesn’t exist in the emulator but is built into the machine.. It’s exciting that you got the c compiler running, is there a patch somewhere??

Also, I don’t get any different results using newest musashi. Seems to not make a difference.

I was able to get cc working after much investigation and wracking my head. Turns out the issue was a 32-bit write that was straddling two mem pages and proper pagefaulting wasn’t occurring. cc is working! But honestly I still can’t get the system to boot properly during the 12-disk install process — I get a hang after the “your screen will now be setup” after the “to use your telephone” popup… pretty frustrating. I had to use your hd.img, thanks for posting! otherwise I wouldn’t have ever been able to get into the system

Oh, got ya!

When I pulled the source down, I manually put the latest Musashi in there. I totally forgot about that as I remember now wondering why it wasn’t pointing to HEAD. Probably as the refactored softfloat thing breaks the nice top level Makefile?

At any rate, I’m using the latest version. The C compiler still breaks…. I haven’t tried running each stage individually, I suspect that may work as there won’t be any ‘pipes’ or shared memory scenarios. I think.

musashi folder in https://github.com/philpem/freebee/tree/master/src links to https://github.com/kstenerud/Musashi/tree/3e0547b1aeee199580a1da37be092fa79f401d31
which is not the latest.

In reply to Roy.

it should be the latest one, dec 15 2019

https://github.com/kstenerud/Musashi/commit/6f04ba062ef4344157b4e6ea918acff6190caf94

m68kcpu.c has “Version 4.60“.

So it’s the latest version.
