-LyX has been tested with all Qt versions since Qt 4.4.0. For compilation

- ldd `which lyx` | grep fontconfig
+For full LyX usability we suggest to use Qt 5.6 and higher, or at the
+very least Qt 5.4. For compilation you need to compile against at least
+Qt 4.8 which has been widely tested, and for Windows we advise at least
+Qt 4.8.4. The only special point to make is that you must ensure that

-If, however, your version of Qt does not use fontconfig, then TeX
-fonts should be added to the font path. 'man xset' is your friend.
* Other things to note
-If you make modifications to files in src/ (for example by applying a
-patch), you will need to have the GNU gettext package installed, due

+If you make modifications to the source that affect any of the

+0.16.1 is needed). You can get the latest version from:

The two following programs should be available at configuration time:
- o LaTeX2e should be correctly setup for the user you are logged in
- as. Otherwise, LyX will not be able to run a number of tests. Note
- that users can run these tests manually with Tools>Reconfigure.
-
- o Python 2.3 or newer installed to be able to import older LyX files
- with the lyx2lyx script (this script is called automatically when
- opening a file). Python 3.0 or later is not supported.

+ that are executed by external scripts, such as the automatic
+ configuration step and the import of older LyX documents with the
