It may also work under later versions of VisualStudio. -You should be familiar with VisualStudio before using this directory. - -Initial preparations -==================== -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. - -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.) - -Linking your application -======================== -Normally you should link against the 'release' configuration. This builds a -DLL for libpng with the default runtime options used by Visual Studio 2010. -In particular the runtime library is the "MultiThreaded DLL" version. -If you use Visual Studio defaults to build your application you will have no -problems. - -If you don't use the Visual Studio defaults your application must still be built -with the default runtime option (/MD). If, for some reason, it is not then your -application will crash inside libpng16.dll as soon as libpng tries to read -from a file handle you pass in. - -If you do not want to use the DLL, for example for a very small application, -the 'release library' configuration may be more appropriate. This is built -with a non-standard runtime library - the "MultiThreaded" version. When you -build your application it must be compiled with this option (/MT), otherwise -it will not build (if you are lucky) or crash (if you are not.) - -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 unless you have heap corruption problems that you can't -track down.) - -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. |
