Actually, the LyX configure is not working so I have no
textclasses and
I cannot "Reconfigure...".
The console shows the following (which might be related):
support\Systemcall.cpp (261): Systemcall: 'python -tt
"C:/Users/Daniel/LyXSource/lyx/lib/configure.py"
--binary-dir="C:/Users/Daniel/LyXSource/lyx-build/LYX_INSTALLED/bin/"'
did not start!
support\Systemcall.cpp (262): error The process failed to start.
Either
the invoked program is missing, or you may have insufficient
permissions
to invoke the program.

This looks wrong to me. Binary-dir and the path to configure.py
should be related.
I would have expected configure.py to lie in
"C:/Users/Daniel/LyXSource/lyx-build/LYX_INSTALLED/Resources/"
(I may be wrong of course)
Next question:
How did you start lyx?
If you want to use the source dir as system dir (instead of installed
dir) then you may start lyx with
# lyx -sysdir "C:/Users/Daniel/LyXSource/lyx/lib"
Kornel
I was starting LyX from
C:/Users/Daniel/LyXSource/lyx-build/LYX_INSTALLED/bin/
... But still get
Library directory: ~\LyXSource\lyx\lib\
Since configure.py is indeed in
"C:/Users/Daniel/LyXSource/lyx-build/LYX_INSTALLED/Resources/"
I tried
# .\LyX.exe -sysdir "C:\Users\Daniel\LyXSource\lyx-build\LYX_INS
TALLED"
Expecting LyX to change the system directory accordingly. But still get
the same error.
Here is all the stuff I am seeing in the console until I have created a
new document. Maybe something makes sense:
PS C:\Users\Daniel\LyXSource\lyx-build\LYX_INSTALLED\bin> .\LyX.exe
-sysdir "C:\Users\Daniel\LyXSource\lyx-build\LYX_INS
TALLED"

Warning: No python v2.x or 3.x binary found.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
That's a main reason. Without python in path, you can neither
configure nor read old lyx-files.
(lyx2lyx needs python for instance)

I reinstalled Python and noticed that the option to set the PATH is not
checked by default. So I checked it. This should probably be mentioned
in the documentation on building LyX on Windows.
I am back to a python problem, I guess. I just redid the whole procedure
for compiling LyX. I have changed nothing else on my system. Here is the
error I get when (re)configuring LyX:

Not sure why LyX does not find the python binary any more...
Daniel
How do you start lyx? You could write a wrapper .bat file which sets the PATH
accordingly,
before starting lyx.
I guess I'll have to look into that then.
You know, this is not a python or lyx problem, but the environment in which
you start lyx is not OK.
Not sure I understand the comment about the environment. The environment
I am using is Windows 10, right? So Windows 10 is not OK? Not sure what
you mean. I have instructed python during installation to add to the
PATH and it was added. So, I don't see why LyX does not find it.
Daniel
No, the environment are the settings you use. One of them is PATH.
Some other are for example LANGUAGE, HOME, USER, NLSPATH, TMPDIR.
(Okay, maybe the right term is "environment variable"?)
So, my PATH (or LANGUAGE, etc.) is set wrong? I just had a look at it
and they seem all right. What makes you think they are wrong?
LyX outputs:
Looking for python v2.x or 3.x ...
Examining C:/Program Files/MiKTeX 2.9/miktex/bin/x64//pythontex.exe
Warning: No python v2.x or 3.x binary found.
Doesn't that indicate that LyX is looking at the wrong place and then
maybe gives up too early? I have
C:/Program Files/MiKTeX 2.9/miktex/bin/x64/
in the global PATH. And there is in fact a pythontex.exe. But python
installed itself only in the local PATH. Could it be that LyX gets
confused by this set up? (But the setup itself seems correct.)
I am still wondering why it worked before though...
Daniel
