Glenn Randers-Pehrson + +This code is released under the libpng license. +For conditions of distribution and use, see the disclaimer +and license in png.h + +This directory contains support for building libpng under MicroSoft +VisualStudio 2010. It may also work under later versions of VisualStudio. +You should be familiar with VisualStudio before using this directory. + +This is a slightly modified copy of the 'vstudio' solution from libpng +1.5; it is intended to provide compatibility for libpng 1.4 with later +releases of zlib (from 1.2.4) and to provide a migration aid for 1.5. + +A 'VB' DLL is no longer produced - use the standard 'Release' DLL. + +Initial preparations +==================== +You should install the 'official' build of zlib on your system - follow the +instructions provided on http://www.zlib.net. When a new release is being +made of zlib the instructions disappear for a while until the new official +build is available. You will have to wait. + +You must enter some information in zlib.props before attempting to build +with this 'solution'. Please read and edit zlib.props first. You will +probably not be familiar with the contents of zlib.props - do not worry, +it is mostly harmless. + +Make sure that your official build layout matches the requirements listed +in zlib.props. Prior to zlib-1.2.4 the official build (1.2.3) placed +include and library files in different directories - if you find this +has happened just put them all in the same directory. + +This is all you need to do to build the 'release' and 'release library' +configurations. + +Debugging +========= +The release configurations default to /Ox optimization. Full debugging +information is produced (in the .pdb), but if you encounter a problem the +optimization may make it difficult to debug. Simply rebuild with a lower +optimization level (e.g. /Od.) + +Stop reading here +================= +You have enough information to build a working application. + +Debug versions have limited support +=================================== +This solution includes limited support for debug versions of libpng. You +do not need these unless your own solution itself uses debug builds (it is +far more effective to debug on the release builds, there is no point building +a special debug build.) + +If, despite the previous paragraph, you still feel you need a debug build you +will have to download the zlib source as well (http://www.zlib.net) and include +the directory where you unpack it in zlib.props. This solution will then be +able to build a minimal zlib sufficient for libpng. This build is only +suitable for making a debug libpng. + +The debug build of libpng is minimally supported. Support for debug builds of +zlib is also minimal. You really don't want to do this. + +This solution only supports the Multi-Threaded DLL C Runtime +============================================================ +If you examine the solution you will find that it very deliberately lists +exactly which MicroSoft DLLs it is linking against. It explicitly links +against msvcrt.lib. The debug version links against msvcrtd.lib (this is +why it is a debug version - it's nothing to do with having any special +debug support, it doesn't). + +These versions of the MicroSoft C runtime correspond to the compiler flags +/MD (release) and /MDd (debug) - the "Multi-Threaded DLL" implementation of the +C runtime library. + +If you need to change this then you will have to make sure that both the +compiler flags and the ".lib" in the linker dependences match up. Fortunately +neither zlib nor libpng require libraries other than a C runtime and +kernel32. + +You cannot pass (FILE*) objects from a different runtime (including msvcrtd +to msvcrt) to libpng. If you do then your program will crash within libpng +when it first makes a file read or write call. + +It is likely if you have read this far that you have found you can't avoid +having multiple C runtimes in your program. This is OK, it does work, but +you will have to implement the libpng file read/write callbacks rather than +using the internal libpng default. This is easy. diff -ru4NwbB libpng-1.4.1/projects/vstudio/vstudio.sln libpng-1.4.2rc06/projects/vstudio/vstudio.sln --- libpng-1.4.1/projects/vstudio/vstudio.sln 1969-12-31 18:00:00.000000000 -0600
