Packaging LyX for Windows =============================== Angus Leeming, 07 March 2006 =============================== Preparing the way ================= The very first thing to do on the way to creating a LyX/Win package is to build the sources and install them somewhere accessible. I've written a script, build_lyxwin.sh, that performs all the necessary steps. Please read the preamble and (un)comment those steps that are necessary at the end of the script. The (eventual --- mingw is a *very* slow compiler) result is a lyx package that's almost ready to go in $LYX_SRCS/build/installprefix. Thereafter, the contents of this tree must be manipulated a little. I've written a little script, package_lyxwin.sh, to automate the process: * Copy the DLLs qt-mt3.dll, libiconv-2.dll, mingwm10.dll to the $PREFIX/bin/ directory. These are needed by the LyX executable. * Strip the binaries in $PREFIX/bin/ of all debugging info. * Copy dt2dv.exe and dv2dt.exe to $PREFIX/bin/ and clean_dvi.py to $PREFIX/Resources/scripts/ These are needed to enable dvips, yap et al. to cope with "file names with spaces". * Add formats and converters to the $PREFIX/Resources/configure script so that users can use the clean_dvi script transparently. * Remove all stuff generated by running configure. It makes sense on your machine only, not for whoever is installing LyX. Specifically xfonts/fonts.dir, xfonts/fonts.scale, doc/LaTeXConfig.lyx, lyxrc.defaults, packages.lst and textclass.lst should all be removed. Creating the LyX icons ====================== All icons are to be found in sub-directory icons/. The LyX icons, lyx_32x32.ico and lyx_doc_32x32.ico, are based on .svg files written and realease into the public domain by Andy Fitzsimon: http://openclipart.org/clipart/computer/icons/etiquette-theme/aps/LyX.svg http://openclipart.org/clipart/computer/icons/etiquette-theme/mimetype.svg lyx.svg is Andy's original. lyx_doc.svg is a merger of LyX.svg with mimetype.svg Working on a linux box, I used sodipodi (http://www.sodipodi.com/) to create the .svg file and to export these vector graphics images to 32x32 pixel bitmaps (.png format). Thereafter I used gimp (http://www.gimp.org/) to generate reduced color depth versions (16, 256 colors). Finally, on a WindowsXP machine, I used IconXP (http://www.aha-soft.com/iconxp/) to build the .ico files from these .png files at differing resolutions. Adding the LyX icons to lyx.exe =============================== ******************************************************************** NOTE: Run 'strip' on lyx.exe before adding any images to it. 'strip' will not work after images have been added. $ strip lyx.exe j:\mingw\bin\strip.exe: lyx.exe: File in wrong format ******************************************************************** Windows executables can store various "resources", including images. I used ResourceHacker (http://rpi.net.au/~ajohnson/resourcehacker) to add the LyX icons to the .exe file. Fire up ResHacker.exe and load lyx.exe File>Open... lyx.exe Action>Add a new Resource... Open file with resource ... lyx_32x32.ico Resource Type will be set to "ICONGROUP" Set Resource Name to "1". (No inverted commas.) Add Resource The icon will be shown in the main Resource Hacker window under Icon Group>1>0 and as Icon>5[0-3]. Repeat for lyx_doc_32x32.ico, setting the Resource Name to "2". Save the modified lyx.exe. Resource Hacker will copy the original to lyx_original.exe. Remove it. Building the LyX installer ========================== At this point my build/installprefix tree now contains everything that is to be released as a LyX/Win package. All that remains to do is to generate a Windows installer for it. I've written a script for NSIS (http://nsis.sourceforge.net/) to compile into an installer. You'll need to compile and install lyx_path_prefix.dll. From the comments in lyx_path_prefix.C: /* Compile the code with * * g++ -I/c/Program\ Files/NSIS/Contrib -Wall -shared \ * lyx_path_prefix.c -o lyx_path_prefix.dll * * Move resulting .dll to /c/Program\ Files/NSIS/Plugins */ Thereafter, you'll be able to build the installer itself: $ /makensis lyx_installer.nsi creating lyx_setup_136.exe ready to ship.
