Frequently Asked Questions (FAQ)
================================

Below are some frequently asked questions in three areas, with
associated answers.

OpenModelica General
--------------------

- Q: OpenModelica does not read the MODELICAPATH environment variable,
even though this is part of the Modelica Language Specification.

- A: Use the OPENMODELICALIBRARY environment variable instead. We have
temporarily switched to this variable, in order not to interfere
with other Modelica tools which might be installed on the same
system. In the future, we might switch to a solution with a
settings file, that also allows the user to turn on the
MODELICAPATH functionality if desired.

- Q: How do I enter multi-line models into OMShell since it evaluates
when typing the Enter/Return key?

- A: There are basically three methods: 1) load the model from a file
using the pull-down menu or the loadModel command. 2) Enter the
model/function as one (possibly long) line. 3) Type in the model
in another editor, where using multiple lines is no problem, and
copy/paste the model into OMShell as one operation, then push
Enter. Another option is to use OMNotebook instead to enter and
evaluate models.

OMNotebook
----------

- Q: OMNotebook hangs, what to do?

- A: It is probably waiting for the omc.exe (compiler) process. (Under
windows): Kill the processes omc.exe, g++.exe (C-compiler),
as.exe (assembler), if present. If OMNotebook then asks whether
to restart OMC, answer yes. If not, kill the process
OMNotebook.exe and restart manually.

- Q: After a previous session, when starting OMNotebook again, I get a
strange message.

- A: You probably quit the previous OpenModelica session in the wrong
way, which left the process omc.exe running. Kill that process,
and try starting OMNotebook again.

- Q: I copy and paste a graphic figure from Word or some other
application into OMNotebook, but the graphic does not appear.
What is wrong?

- A: OMNotebook supports the graphic picture formats supported by Qt 4,
including the .png, .bmp (bitmap) formats, but not for example
the gif format. Try to convert your picture into one of the
supported formats, (e.g. in Word, first do paste as bitmap
format), and then copy the converted version into a text cell in
OMNotebook.

- Q: I select a cell, copy it (e.g. Ctrl-C), and try to paste it at
another place in the notebook. However, this does not work.
Instead some other text that I earlier put on the clipboard is
pasted into the nearest text cell.

- A: The problem is wrong choice of cursor mode, which can be text
insertion or cell insertion. If you click inside a cell, the
cursor become vertical, and OMNotebook expects you to paste text
inside the cell. To paste a cell, you must be in cell insertion
mode, i.e., click between two cells (or after a cell), you will
get a vertical line. Place the cursor carefully on that vertical
line until you see a small horizontal cursor. Then you should
past the cell.

- Q: I am trying to click in cells to place the vertical character
cursor, but it does not seem to react.

- A: This seems to be a Qt feature. You have probably made a selection
(e.g. for copying) in the output section of an evaluation cell.
This seems to block cursor position. Click again in the output
section to disable the selection. After that it will work
normally.

- Q: I have copied a text cell and start writing at the beginning of
the cell. Strangely enough, the font becomes much smaller than it
should be.

- A: This seems to be a Qt feature. Keep some of the old text and start
writing the new stuff inside the text, i.e., at least one
character position to the right. Afterwards, delete the old text
at the beginning of the cell.

OMDev - OpenModelica Development Environment
--------------------------------------------

- Q: I get problems compiling and linking some files when using OMDev
with the MINGW (Gnu) C compiler under Windows.

- A: You probably have some Logitech software installed. There is a
known bug/incompatibility in Logitech products. For example, if
lvprcsrv.exe is running, kill it and/or prevent it to start again
at reboot; it does not do anything really useful, not needed for
operation of web cameras or mice.
