    ImpLib SDK

    ImpLib SDK

    ImpLib SDK produces custom Import libraries for Windows DLL

    ImpLib SDK combines free programming tools for authoring custom import libraries for Windows DLL (32 and 64 bit). The SDK supports advanced features, like cdecl2stdcall conversion, importing by ordinal, removing original thunk, storing symbols from different DLL files in a single import library. The ImpLib SDK is also useful to overcome any legal restrictions when redistributing the import libraries for certain DLL files, like the Microsoft® C++ runtime. The import libraries for the CRT or STL are part of the Windows SDK. Even though the SDK is available for free, redistributing these files is not allowed according to the current license agreements. An alternative is to generate these import libraries using the ImpLib SDK, as it doesn't restrict redistribution. The ImpLib SDK is free even for commercial use and redistribution of any kind, as long as all copyrights are preserved.

    WinCMOC (M6809 C Compiler)

    WinCMOC (M6809 C Compiler)

    A C Compiler/Editor for Retro 6809 Machines (Colour Computer/Dragon)

    WinCMOC v0.6 is here! So many new features, I cant remember them all. Please uninstall old versions before installing. This is a port of the CMOC compiler (written by Pierre Sarrazin) to Windows. Currently CMOC does not support linking, so, I've written front end tools which edit CMOC's output so that it can be assembled and linked via LWTOOL's. A simple C editor in included which makes it easy to compile/build and run the xroar emulator. Please visit the CMOC website: http://perso.b2b2c.ca/~sarrazip/dev/cmoc.html CREDITS LWTools - Portable tools for the Motorola 6809/6309 http://lwtools.projects.l-w.ca/ mcpp - A Portable C Preprocessor http://mcpp.sourceforge.net/ Artistic Style - Automatic Source Formatter http://astyle.sourceforge.net/ XRoar - Dragon & CoCo emulator http://www.6809.org.uk/xroar/ CMOC - 6809 cross-compiler for a small C-like language http://perso.b2b2c.ca/~sarrazip/dev/cmoc.html
