Building LyX/Mac-1.5 Ronald Florence Modified by Bennett Helm , Anders Ekberg and Jean-Marc Lasgouttes . LyX/Mac is built from the LyX source, the GPL-licensed Trolltech Qt/Mac library, and a custom application bundle. You will need the MacOSX development tools. The procedure described here builds LyX linked with a static Qt library. Also note that building LyX/Mac requires gcc version 4.0 or higher. (You can check your version by entering "gcc -v" in the Terminal; you can change your gcc version to version 4.0, for example, by entering "sudo gcc_select 4.0".) PREREQUISITES Note: Only Qt/Mac is needed for building official LyX releases, and so steps 2 and 3 can be skipped in these cases. Those wanting to build developmental versions must have automake and gettext as well. 1. Qt/Mac Opensource Edition, version 4. This library is GPL- licensed and can be downloaded from . To compile it, create a directory where you want to install QT4. In the following, the full path to this directory is called /path/to/QT4 Decompress Qt/Mac in a convenient directory, cd to the top of the Qt source hierarcy, and enter: ./configure -static -no-exceptions -nomake examples -nomake tools -nomake demos -prefix /path/to/QT4 make make install cd /path/to/QT4/lib rm *.la 2. [Needed only for developmental builds:] automake, version 1.10 or higher (check with automake --version). Probably the easiest way to get this is to use MacPorts (from http://www.macports.org/) and install automake using sudo port install automake 3. [Needed only for developmental builds:] gettext version >= 0.12 (check with gettext --version). If the installed version is insufficient the easiest way to obtain a later version is to use MacPorts (from http://www.macports.org/) and install gettext using: sudo port install gettext 4. [Useful to simplify detection of Qt:] pkg-config >= 0.9.0. Again, the simplest way is through MacPorts: sudo port install pkgconfig BUILD INSTRUCTIONS In what follows, /path/to/LyX.app is the location where you want LyX to create the LyX binary. You should substitute something appropriate, like: ~/Desktop/LyX.app. Also, substitute the appropriate path to where you installed Qt for /path/to/QT4 (as above). (a) Official Releases If you did not install pkg-config, first set the LDFLAGS variable: export LDFLAGS="-framework Carbon -framework OpenGL -framework AGL -framework QuickTime -framework Cocoa" Then, cd to the top of the LyX source hierarchy, and enter: ./configure --prefix=/path/to/LyX.app --with-version-suffix=-1.6 --with-qt4-dir=/path/to/QT4 --with-included-gettext --enable-optimization=-Os make make install-strip (Note that the --with-version-suffix=-1.6 option will result in LyX's user's directory being located at ~/Library/Application Support/LyX-1.6) (b) Developmental Versions (svn checkouts) Building LyX from developmental sources requires a few more steps. Instead of the instructions above, do the following: If you did not install pkg-config, first set the LDFLAGS variable: export LDFLAGS="-framework Carbon -framework OpenGL -framework AGL -framework QuickTime -framework Cocoa" Then, cd to the top of the LyX source hierarchy, and enter: ./autogen.sh ./configure --prefix=/path/to/LyX.app --with-version-suffix=-1.6 --with-qt4-dir=/path/to/QT4 --with-included-gettext --enable-optimization=-Os make make install-strip Note that by default svn versions use some extra debugging code that somewhat slows LyX down. If it is a real problem, you can pass the option --enable-build-type=release to configure.
