Content ======= libgig actually consists of three parts: - RIFF classes (RIFF.h, RIFF.cpp): Provides convenient methods to parse and access arbitrary RIFF files. - DLS classes (DLS.h, DLS.cpp): They're using the RIFF classes to parse DLS (Downloadable Sounds) Level 1 and 2 files and provide abstract access to the data. - gig classes (gig.h, gig.cpp): These are based on the DLS classes and provide the necessary extensions for the Gigasampler file format. Requirements ============ I simply used automake & co this time so you will need to have automake, autoconf and libtool installed. I used the following versions: automake 1.6.3 autoconf 2.57 If you want to compile the 'gigextract' application that comes with these sources then you will additionally need to have libaudiofile (>= 0.2.3) or libsndfile (>= 1.0.2) installed. Note: for Windows systems only libsndfile is available. Non-POSIX systems ================= If you don't have a POSIX system, you have to set 'POSIX' to '0' in RIFF.h. Instead of using POSIX calls then standard C calls will be used for file access. This applies e.g. to Windows systems. I would appreciate if somebody sends me his MS Visual Studio / .NET, Borland C++ Builder or Apple XCode project file! This might help others to conveniently compile libgig on those platforms as well. Compiling ========= You can either compile the sources and install the library directly on your system or you can create Redhat or Debian packages. a) Compiling and installing directly Use 'make -f Makefile.cvs && ./configure && make' to compile the library, all tools, demo applications, documentation and install them with 'make install'. You can use 'make distclean && make -f Makefile.cvs clean' to clean up everything again. b) Creating Debian packages Use 'make -f Makefile.cvs && dpkg-buildpackage -rfakeroot -b' to compile and create the Debian packages. This will generate 3 Debian packages: libgig: Contains the shared library files. libgig-dev: Contains the header files and documentation for building applications using libgig. gigtools: Contains the tools and demo applications. You can use 'fakeroot debian/rules clean && make -f Makefile.cvs clean' to clean up everything again. c) Creating Redhat packages You need to have the rpmbuild tool installed and properly configured to create RPM packages. To create the RPM packages do the following: * Get .spec file generated by ./configure and edit it as appropriate. * Copy the source tarball to "/usr/src//SOURCES" directory, where is dependent to the system you are using. For SuSE will be "packages", for Mandrake is "RPM" and for Redhat / Fedora always equals "redhat". * Build the rpm(s) by invoking 'rpmbuild -bb ' from the command line. On success, the resulting rpm(s) can usually be found under the proper "/usr/src//RPMS/" directory. Tools ===== Beside the actual library there are four applications: gigdump: Demo app that prints out the content of a .gig file. gigextract: Extracts samples from a .gig file. dlsdump: Demo app that prints out the content of a DLS file. rifftree: Tool that prints out the RIFF tree of an arbitrary RIFF file. API Documentation ================= If you have Doxygen installed you can generate the API documentation by running 'make docs' in the sources' top level directory. The API documentation will be generated in the 'doc' subdirectory. Patches ======= If you find bugs or have improvements, your patches are always welcome! Send them either directly to me or to the LinuxSampler developer's mailing list . Credits ======= The initial library was based on the reverse engineering effort of Paul Kellett and Ruben van Royen. We owe current support for the quite new Gigasampler v3 format to Andreas Persson. Please also have a look at the ChangeLog for all those who contributed. Thanks for your great work!
