ECL-11.1.1 fails to compile maxima on WIndows 7 / Cygwin 1.7.9

[dimpase]

The problem is specific to Windows 7, and (most probably---untested) other newer than XP Windows releases, like Vista, etc. On these systems Cygwin has still some glitches related to fork etc... Note that it builds fine under WinXP.

Symptoms - dreadfully looking errors on address spaces of DLLs with temporary names, and dead or dying forks...

I've posted this to the ecl list, but it would probably help if you attached build logs of ECL and Maxima.

The ECL developer Juanjo has written on the ECL and sage-devel lists:

I know about these bug reports -- similar ones appeared on a different context --. Unfortunately I am at a peak of work load and will solve them slower than usual. Thanks for reminding.

[kcrisman]

Data point: Maxima compiled successfully on my Windows 7 machine just now. ./sage -maxima worked and I integrated 2x. I did not do anything special to get this to happen.

[kcrisman]

I should say that I did see several "fork" and "waiting for resource" errors, but those apparently weren't fatal. So it may be that Maxima and anything else that needs fork will work randomly, depending on what else the system is up to.

[kcrisman]

This time Maxima failed to build with the usual fork errors. I'm trying make again.

---

Juanjo reports that he has changed the way ECL handles forking on Cygwin so that this will not be a problem - the Maxima folks want it to work too - though it removes some capabilities on Cygwin. Apparently, that won't be a problem for Sage, however.

[kcrisman]

dimpase reports on  this sage-devel thread (at the very end) that Maxima now compiles on Windows 7 with the new ECL spkg for Lion at #11884.

My guess is that if Dima positively reviews as sage-invalid, that would be sufficient. This would not close #11502 since that is an XP problem, though likely we will simply just forget about XP soon.

[kcrisman]

Dima, I've set this one as well to sage-invalid. If you agree with this, just set to positive review.
