<br>Hi folks,<br>
<br>
As was mentioned in the Squeak Board minutes, I've been working on<br>
getting Squeak running on SmartOS. (SmartOS is a newish distribution<br>
of Illumos, which is a fork of OpenSolaris, which is apparently no<br>
longer open, now that Oracle owns it. Anyway, it's a flavour of<br>
Solaris.)<br>
<br>
Attached is a patch that lets me build the VM and open an image in a<br>
SmartOS zone.<br>
<br>
I ran into a few issues, which I'll detail below:<br>
<br>
1) I tried to do a proper autoconf check for the existence of headers<br>
such as <sys/sockio.h> and <sys/ucontext.h>, but I ran afoul of very<br>
strange behaviour from the libtool script that my regenerated<br>
configure script created. (Geez, how many levels of code generation do<br>
these GNU guys think is healthy?) I was able to create the config.h<br>
file that I wanted, but then linking didn't work anymore. For now I've<br>
just used the __sun__ preprocessor definition (apparently<br>
automatically defined by the compiler) for conditional compilation.<br>
<br>
2) It looks like the image runs ok, but when I try to connect a VNC<br>
client (SmartOS has no GUI), the VM receives a SIGPOLL/SIGIO signal<br>
and exits. Fixing that probably requires more significant changes than<br>
I've made so far, so if anybody has suggestions on how to tackle it,<br>
I'd love to hear them.<br></blockquote><div><br></div><div>You at least need to establish a signal handler for SIGIO (should be done in platforms/unix/vm/aio.c). Or it could be that the signal handler is one-shot, and on the second SIGPOLL/SIGIO the VM quits. You need the signal handler for sigaction to not be one-shot, which you'd control by using sigaction instead of the simple signal in aio.c. check the manual page for signal and sigaction and see what they say about SA_RESETHAND.</div>

<br>
If there's some other method of submitting the patch that would be<br>
more convenient of the maintainers, I'm happy to do that instead.<br></blockquote><div><br></div><div>A tar of the changed files as well as patch is as good as it gets I think.</div><div><br></div><div>Ta!</div><div>
