For anyone wanting to run gxemul as it is on Windows, I’ve just tested and it will successfully compile and run the MIPS emulator and run ULTRIX using Cygwin under Windows + any X server.

(There is an issue where the X servers own cursor is displayed and moves not synchronized with the guest os X cursor).

If you happen to have Intel graphics, disable ctrl+alt+left for screen rotation as that is also the key combination to release the cursor from the emulator.

Oh, and bash 1.14 and pdksh both compile.

Use these, fellow OSF/1 afficionado:

This is perl 5, version 32, subversion 0 (v5.32.0) built for mips-mips_osf1

Reading specs from /usr/local/gcc-3.0.4/lib/gcc-lib/mips-dec-osf2/3.0.4/specs
Configured with: ../gcc-3.0.4/configure –prefix=/usr/local/gcc-3.0.4 –enable-languages=c,c++,f77 : (reconfigured)

Later versions are off the table.

Other GCC versions from the working variety: egcs-1.1.2, gcc-2.8.1, gcc-2.95.3

And both binutils-2.9.1 and binutils-2.10.1 suck, as noted.

By all means disable X: set XLOGIN to “false” or anything, and start an xterm script from inittab with for example DISPLAY=192.168.1.198:1

Then redirect port localhost 6001 to wherever with whatever (ssh/redir.tgz, etc)

Yeah, it’s an interesting system! Getting anything modern to compile for it has been a struggle though 😀 GCC 3 requires perl, which doesn’t want to compile. Bash causes the ancient MIPS c compiler to dump core… I think I’ll with GCC 2.7 first, I read somewhere that that will work…
I’ll also have to see if I can get the serial console to work, it would free up memory to run without X.

wow super cool! Mach rules!

Sure! There is a lot of drift in gxemul, so newer doesn’t mean better..

Just as my crap is like a ‘omg it linked!’ bare effort. I’m surprised it runs anything to be honest, but that isn’t the result of my work.. I’m just a monkey banging a keyboard lol

A couple of years later I revisited it, refining the patches so that the project had a clear graphics interop layer that had implementations for both Windows and Unix. Some anecdotes: Originally I rewrote the shell scripts in perl, but later decided it was simpler to write a simple shell emulator in perl and invoke that instead. Also, the build times were very slow in Windows because of all the processes launched so I switched some code in the makefiles to use awk to cut the build times in half.

In the end, I got interested in other things and never completed the project, but I still have my patches lying around if there’s interest in looking them over to see if there’s anything of interest to your efforts.

The iso’s you know where to download right? and the Irix 6.X source code? 😛

Yes I have been following that, but it only emulates an SGI Indy, and its slow as a sloth.
GXEmul has much better performance and emulates the O2 machine
