I think you posted this to the wrong list, and I bet a number of people
are confused, I removed the wrong list, and added the correct list.

And yes, the host version seems to have that issue, at best I have got it to
work for a couple of key presses but never longer, I have never been able to get
it working, and it does apparently work for a couple of people, and it does fail
for a couple of people, I would bet more likely it is a library issues of some
sort.    There was a discussion title "make host results in unresponsive" in
February.

Yes it was the wrong list.  Thank you.  I have read the previous post and it appears to be no solution to the issue, correct?  Because of the issue I have not been able to do any development.  Does it work for anyone?  If so can you post library/gcc versions you have installed?

Thank you Mike

It works fine for me. Sometimes I have to switch focus away to another
window and then back again upon startup, or click on the text to bring
focus into the host build, but once i've done that it works fine. I'm
afraid the only way that the issues some people are having with the host
build are going to be resolved would be if one of those people debugged
the problem themselves. I can't offer any help because it "works for me".

Cheers,

Simon

Well,

It works on Fedora 7 with no major updates except kernel, but fails on Fedora 8
with no major updates except kernel.   It is almost certainly a library issue,
the X server is the exact same machine running the exact same OS and X.

Yep...it does sound like a library issue...Or more accurately an issue
with how microwindows interfaces with the libraries on your FC 8 system.
I'd say it's almost certainly fixable at the microwindows/nano-X end, but
I can't debug it.

Cheers,

Simon

Well...whatever was causing this problem finally propogated through to
newer releases of Debian and Ubuntu, so I've been able to chase this bug.
It looks like the method that microwindows was using to select() to wait
for input was failing to work. I've worked around this by directly
checking the X11 event queue. So, anyway, the changes I pushed to the main
git repository a few days ago should make the host build work. They won't
have any adverse affects on the MVP build (since the patch isn't applied
for that), but might cause some issues with timers and the like on the
host build.


Anyway, anyone who wants to develop/debug using the host build should pull
the latest updates from the main git repo.

Cheers,

Simon
