 Open its solution and compile the libFLAC_static project. By default, optimization for this library is set to "full" in release builds, which will prevent you from performing incremental debug builds later on, so make sure to set it to "Maximize speed" (or anything other than "Full optimization"), otherwise it will be impossible to build incremental debug builds later on. Check the introductory section for more information. Also, FLAC OGGs are not needed, so support for these can be dropped by going to the libFLAC_static project settings and removing the FLAC__HAS_OGG switch from C/C++->Preprocessor->Preprocessor Definitions.
-'''Note for x64''': After converting the Win32 target to x64 you will need to adapt some file settings. First of all you will need to disable all *.nasm files in the "libFLAC_static" project, this can be easily done by right clicking on them and selecting "Properties", now set "Excluded From Build" to "true". Next you will need to adapt the Preprocessor Definitions: First of all remove the following defintions: "FLAC__CPU_IA32", "FLAC__HAS_NASM" and "FLAC__USE_3DNOW", now also add "FLAC__NO_ASM". Last but not least you will need to apply the following patch file to "bitreader.c" of the "libFLAC_static" project: [http://robertmegone.com/scummvm/build/flac.patch flac.patch]

 Open the solution under projects\vstudio. You also need zlib to compile this library, which must be placed in a folder named "zlib" outside libpng's directory. You need to change the settings of zlib like you have done before (i.e. from "Multi-Threaded DLL (/MD)" to "Multi-Threaded (/MT)"). Check the zlib section for more information.
