Game_Music_Emu Change Log
|
||||
-------------------------
|
||||
|
||||
Game_Music_Emu 0.6.1
|
||||
--------------------
|
||||
|
||||
- Moved repository to Bitbucket since Google Code announced they would
|
||||
shutdown this year.
|
||||
|
||||
- Packaging improvements:
|
||||
- Honor $LIB_SUFFIX for installed pkg-config metadata.
|
||||
- Support setting BUILD_SHARED_LIBS to OFF to build libgme as a static
|
||||
library. (Pass -DBUILD_SHARED_LIBS=OFF when running cmake).
|
||||
Thanks to lachs0r.

Current Maintainer: Michael Pyne <mpyne@purinchu.net>
|

|
||||
Getting Started
|
||||
---------------
|
||||
Build a program consisting of demo/basics.c, demo/Wave_Writer.cpp, and
|
||||
all source files in gme/. If you have CMake 2.6 or later, execute
|
||||
all source files in gme/.
|
||||
|
||||
run cmake
|
||||
cd demo
|
||||
run make
|
||||
Or, if you have CMake 2.6 or later, execute at a command prompt (from the
|
||||
extracted source directory):
|
||||
|
||||
Be sure "test.nsf" is in the same directory as the program. Running it
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ../ # <-- Pass any needed CMake flags here
|
||||
make # To build the library
|
||||
cd demo
|
||||
make # To build the demo itself
|
||||
|
||||
Be sure "test.nsf" is in the same directory as the demo program. Running it
|
||||
should generate the recording "out.wav".
|
||||
|
||||
You can use "make install" to install the library. To choose where to install
|
||||
the library to, use the CMake argument "-DCMAKE_INSTALL_PREFIX=/usr/local"
|
||||
(and replace /usr/local with the base path you wish to use). Alternately, you
|
||||
can specify the base path to install to when you run "make install" by passing
|
||||
'DESTDIR=/usr/local' on the make install command line (again, replace
|
||||
/usr/local as appropriate).
|
||||
|
||||
To build a static library instead of shared (the default), pass
|
||||
-DBUILD_SHARED_LIBS=OFF to the cmake command when running cmake.
|
||||
|
||||
A slightly more extensive demo application is available in the player/
|
||||
directory. It requires SDL to build.
|
||||
|
||||
Read gme.txt for more information. Post to the discussion forum for
|
||||
assistance.
