These four steps will compile, test and install LyX:
- 0) Linux users beware: You need qt4 and qt4-devel packages
+ 0) Linux users beware: You need qt5 and qt5-devel packages
of the same version to compile LyX.
In general, it is also recommended to have pkg-config
1) ./configure configures LyX according to your system. You
may have to set --with-qt-dir=<path-to-your-qt-installation>
- (for example, "--with-qt-dir=/usr/share/qt4/") if the
+ (for example, "--with-qt-dir=/usr/share/qt5/") if the
environment variable QTDIR is not set and pkg-config is not
available.
-----------------------------
If you have checked this out from Git, you need to have:
-* automake (supported versions are 1.8--1.15)
-* autoconf (supported versions are 2.60--2.69)
+* automake (supported versions are 1.14--1.16)
+* autoconf (supported versions are 2.65--2.69)
Then type "./autogen.sh" to build the needed configuration
files and proceed as stated above/below.
Requirements
------------
-First of all, you will need a recent C++ compiler, where recent means
-that the compilers are close to C++ standard conforming like gcc (at
-least 4.x) or clang. Note that the compiler will be used in C++11 mode
-when possible.
+First of all, you will need a C++11 standard conforming compiler, like gcc (at
+least 4.7) 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 Qt 4.x and at least Qt 4.8 which
-has been widely tested. For compilation you need to compile against at
-least Qt 4.5.0 and at Windows we advise at highest Qt 4.8.4. 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.
+For full LyX usability we suggest to use Qt 5.6 and higher, or at the

To build LyX with spell checking capabilities included you have to
install at least one of the development packages of the spell checker

The `gprof' build type compiles and links with -pg option with gcc.
- o --with-extra-lib=DIRECTORY that specifies the path where LyX will
- find extra libraries (qt4) it needs. Defaults to NONE

(i.e. search in standard places). You can specify several
directories, separated by colons.
Similarly, if you want to force the use of a specific compiler, you can
give a value to the CXX variable.

-Problems
---------
-
-This section provides several hints that have been submitted by LyX
-team members or users to help compiling on some particular
-architectures. If you find that some of these hints are wrong, please
-notify us.
-
- o On SUN Sparc Solaris, you need gnumake. The LyX makefiles do not
- work with Solaris make.
-
- The Solaris 8 ar seg-faults trying to build the insets library. You
- will need to use the ar from the GNU binutils for this subdirectory.
- There is no problem with the Solaris 9 and 10 ar.
-
- Qt4 uses the Xrender X11 extension for antialiased fonts. This
- extension was added to Xsun starting from the Solaris 10 8/07
- release, but it is not activated by default. To activate it, you
- must issue (as root) the following command:
- svccfg -s svc:/application/x11/x11-server setprop options/server_args=+xrender
- and then restart the X server.
-
- There is a problem with the fontconfig library shipped with
- Solaris 10 8/07 causing a seg-fault when it is used by Qt4.
- Until this is fixed, a workaround is replacing the shared library
- /usr/lib/libfontconfig.so.1 with a copy from a previous release or
- installing a new version of fontconfig from http://www.sunfreeware.com/
-
- On Solaris, the default fontconfig configuration gives preference
- to bitmap fonts at (not so small) sizes. As bitmapped fonts are not
- antialiased, you may prefer changing this configuration. This may be
- done by adding the following stanza
-
- <match target="pattern">
- <edit name="prefer_bitmap">
- <bool>false</bool>
- </edit>
- </match>
-
- to either ~/.fonts.conf (for a per-user change) or /etc/fonts/local.conf
- (for a global system change). The stanza should be added between the
- <fontconfig> and </fontconfig> tags. If neither ~/.fonts.conf nor
- /etc/fonts/local.conf exists, you can create them with the following
- content:
-
- <?xml version="1.0"?>
- <!DOCTYPE fontconfig SYSTEM "fonts.dtd">
- <fontconfig>
- <match target="pattern">
- <edit name="prefer_bitmap">
- <bool>false</bool>
- </edit>
- </match>
- </fontconfig>
