Building AC97SND on windows. 1. Tools required: - Microsoft Visual Studio (version 2005 or later) - Flat assembler Download and install fasm for windows from http://www.flatassembler.net Add fasm directory to windows PATH variable. (To check if this worked, open CMD and type fasm. Fasm's help messages should be visible now.) - pe2kos.exe Can be found in some subdirectories of SVN, official location unknown. This file will need to be placed in the same directory as dependencies, to build the final KolibriOS executable 2. Collecting the dependencies: - sound.lib Source code can be found at \programs\develop\sdk\trunk\sound\src Building this is beyond the scope of this document for now. Alternatively, you can download latest compiled version from the autobuild server. http://builds.kolibrios.org/eng/data/programs/develop/sdk/trunk/sound/src/sound.lib - ufmod.obj Source code is at \programs\develop\libraries\ufmod Build using makeobj.bat Or as above, download from: http://builds.kolibrios.org/eng/data/programs/develop/libraries/ufmod/ufmod.obj - mpg.obj Open ac97snd solution in visual studio, select mpg project and click build -> build mpg 3. Building AC97SND binary You will need to copy all previously mentioned dependencies into the folder that Visual Studio expects to find them. This can be for example: \programs\media\ac97snd\release\ Alternatively, you can add another directory to 'Additional Library Directories' in Projects Linker options. Now select AC97SND project, and click build -> build AC97SND Good luck!
