If you have checked this out from Git, you need to have:
-* automake >= 1.8
-* autoconf >= 2.59d
-* gettext >= 0.16.1
+* automake (supported versions are 1.8--1.15)
+* autoconf (supported versions are 2.60--2.69)
Then type "./autogen.sh" to build the needed configuration
files and proceed as stated above/below.

First of all, you will need a recent C++ compiler, where recent means
-that the compilers are close to C++ standard conforming (gcc 4.x).
+that the compilers are close to C++11 standard conforming like gcc (at
+least 4.3) or clang.
LyX makes great use of the C++ Standard Template Library (STL).
This means that gcc users will have to install the relevant libstdc++
-library to be able to compile this version of LyX.

-For full LyX usability we suggest to use at least Qt 4.8 which has been

-Qt 4.5.0. The only special point to make is that you must ensure that both
-LyX and the Qt libraries are compiled with the same C++ compiler.

To build LyX with spell checking capabilities included you have to
install at least one of the development packages of the spell checker
* 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
-to some dependencies in the makefiles. You can get the latest version

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 2.4 or newer must be installed. Python is used for many
- simple tasks that are executed by external scripts, such as the
- automatic configuration step and the import of older LyX documents
