Make the library looks as a regular C library with well-defined ABI. + * This is also crucial when the library is to be linked with modules in a different + * language, either statically or dynamically. + * 2: Use plugin-like API via C-interface wrapped in a C++ class. This is mainly intended + * for a shared library being dynamically loaded in run-time. To get access to all the library + * services, a client application only needs to bind with a single factory function. + * 3: Use optimised C++ API compatible with the plugin API (type 2). The facade class also wraps + * the C functions but they are invoked directly. This enables the compiler to generate better + * code for the library when linked statically yet being consistent with the plugin-like API. + */ + +#ifdef MT32EMU_API_TYPE +#if MT32EMU_API_TYPE == 0 && (MT32EMU_EXPORTS_TYPE == 1 || MT32EMU_EXPORTS_TYPE == 2) +#error Incompatible setting MT32EMU_API_TYPE=0 +#elif MT32EMU_API_TYPE == 1 && (MT32EMU_EXPORTS_TYPE == 0 || MT32EMU_EXPORTS_TYPE == 2) +#error Incompatible setting MT32EMU_API_TYPE=1 +#elif MT32EMU_API_TYPE == 2 && (MT32EMU_EXPORTS_TYPE == 0) +#error Incompatible setting MT32EMU_API_TYPE=2 +#elif MT32EMU_API_TYPE == 3 && (MT32EMU_EXPORTS_TYPE == 0) +#error Incompatible setting MT32EMU_API_TYPE=3 +#endif +#else /* #ifdef MT32EMU_API_TYPE */ +#if 0 < MT32EMU_EXPORTS_TYPE && MT32EMU_EXPORTS_TYPE < 3 +#define MT32EMU_API_TYPE MT32EMU_EXPORTS_TYPE +#else +#define MT32EMU_API_TYPE 0 +#endif +#endif /* #ifdef MT32EMU_API_TYPE */ + +/* MT32EMU_SHARED should be defined when building shared library, especially for Windows platforms. */ +/* +#define MT32EMU_SHARED +*/ + +#include "globals.h" + +#if !defined(__cplusplus) || MT32EMU_API_TYPE == 1 + +#include "c_interface/c_interface.h" + +#elif MT32EMU_API_TYPE == 2 || MT32EMU_API_TYPE == 3 + +#include "c_interface/cpp_interface.h" + +#else /* #if !defined(__cplusplus) || MT32EMU_API_TYPE == 1 */ #include "Types.h" +#include "File.h" +#include "FileStream.h" #include "ROMInfo.h" #include "Synth.h" +#include "MidiStreamParser.h" -#endif +#endif /* #if !defined(__cplusplus) || MT32EMU_API_TYPE == 1 */ + +#endif /* #ifndef MT32EMU_MT32EMU_H */ diff --git a/audio/softsynth/mt32/sha1/sha1.cpp b/audio/softsynth/mt32/sha1/sha1.cpp new file mode 100644 index 0000000000..a0c5e13a36 --- /dev/null +++ b/audio/softsynth/mt32/sha1/sha1.cpp @@ -0,0 +1,185 @@ +/* + Copyright (c) 2011, Micael Hildenborg + All rights reserved. + + Redistribution and use in source and binary forms, with or without + modification, are permitted provided that the following conditions are met: + * Redistributions of source code must retain the above copyright + notice, this list of conditions and the following disclaimer. + * Redistributions in binary form must reproduce the above copyright + notice, this list of conditions and the following disclaimer in the + documentation and/or other materials provided with the distribution. + * Neither the name of Micael Hildenborg nor the + names of its contributors may be used to endorse or promote products + derived from this software without specific prior written permission. + + THIS SOFTWARE IS PROVIDED BY Micael Hildenborg ''AS IS'' AND ANY + EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED + WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE + DISCLAIMED.
