Abdel,
I tried your LyX/Qt4 and got a bug report for you.
After launching lyx from a cmd.exe terminal, I hit the open file icon
and lyx crashed. Please, attached find a backtrace.
Lyx did not automatically run configure at start, but it asked me if I
wanted the userdir created. Indeed the userdir was empty, so I tried
Tools->Reconfigure but it hung.
I saw a stalled latex process and after killing it the reconfiguration
process went ahead. However, lyx continues crashing when I try to load
a file.
I use all cygwin apps but native miktex and imagemagick. So I tried
running lyx from a cygwin shell and this time the reconfiguration
doesn't stopped and went stright ahead to the end. Still crashes when
trying to open a file, though.
I also tried running the native lyx 1.4.1 I build by myself from a
cmd.exe terminal and it worked flawlessly, but the cygwin lyx 1.5 also
hangs on reconfigure when run from cmd.exe. This pointed me to a
problem with configure.py.
After some investigation it turned out that the python mkstemp()
function uses the directory defined in the TEMP environment variable
if it is set. In a cygwin shell TEMP is not set, so /tmp is used, but
in a cmd.exe TEMP is set to a path in short form dos style
containing '~' characters and this hurts latex.
Please, can you see if the attached patch can be applied to both trunk
and branch?
Thank you.
