Preview has been failing for me with
python: can't open file
''/home/aleem/lyx/devel/lib/scripts/lyxpreview2bitmap.py''
A little debugging in graphics/PreviewLoader.C turns up the reason.
We're invoking Forkedcall (which in turn invokes execvp) with
Calling Forkedcall with
python
'/home/aleem/lyx/devel/lib/scripts/lyxpreview2bitmap.py' ppm
/tmp/lyx_tmpdir16301ez1vtq/lyx_tmpbuf0/0lyxpreview.tex 153 000000
faf0e6
Note the quotes around 'lyxpreview2bitmap.py'. Someone got busy in
LibScriptSearch and protected the name of the script with quotes.
ViewCVS tells me that this happened on 14 September and that the busy
man was Jean-Marc ;-)
In truth, the fault does not lie there at all but in our brain dead
code in Forkedcall::generateChild that attempts to build an 'argv'
array for execvp.
I guess that I should stop procrastinating and merge my intelligent
command line parser into the LyX sources.
