***************************************************************************
|

Mac OS X is UNIX so use the INSTALL instructions in the dirctory
|
||||
above. These instructions are for OS9.

|
||||
BUILDING LIBSNDFILE FOR MACINTOSH (Pre Mac OSX)
|
||||
-----------------------------------------------
|
||||
|
||||
These instructions are current as of libsndfile 0.0.16, and assume the
|
||||
following development environment:
|
||||
|
||||
- MacOS 8.6
|
||||
- Metrowerks CodeWarrior Pro4 (IDE3.3, and all publicly available
|
||||
compiler updates as of June, 1999)
|
||||
- Apple Universal Libraries 3.2
|
||||
|
||||
The following procedure is recommended for building a libsndfile library
|
||||
suitable for inclusion in other MacOS projects:
|
||||
|
||||
1. using CodeWarrior, create a new "Empty Project"
|
||||
|
||||
2. obtain the libsndfile source distribution (see homepage URL below);
|
||||
add all ".c" files found in the top level of the "src", "src/GSM610" and
|
||||
"src/G72x" folders to the project
|
||||
|
||||
3. starting from the factory defaults, adjust the following project
|
||||
settings:
|
||||
- Target Settings panel:
|
||||
linker = "MacOS PPC Linker"
|
||||
- PPC Target panel:
|
||||
project type = "Library"
|
||||
file name = "libsndfile"
|
||||
|
||||
4. grab the "config.h" file from the MacOS directory and replace the default
|
||||
config.h file in the "src" directory
|
||||
|
||||
5. Make the project
|
||||
|
||||
|
||||
CROSSPLATFORM (x86) BUILDS?
|
||||
--------------------------
|
||||
|
||||
For situations in which CodeWarrior is being used to develop a project
|
||||
for dual-platform operation, it is possible to build an x86 version of
|
||||
libsndfile on the mac as well. Use the procedure above to set up the
|
||||
PPC target, then perform the following steps:
|
||||
|
||||
6. create a new target, by cloning the existing ppc target (created
|
||||
above)
|
||||
|
||||
7. adjust the following project settings:
|
||||
- Target Settings panel:
|
||||
linker = "Win32 x86 Linker"
|
||||
- x86 Settings panel:
|
||||
project type = "Library (LIB)"
|
||||
file name = "libsndfile.x32.lib"
|
||||
- Access Paths panel:
|
||||
add this compiler-relative path at the TOP of "System Paths"
|
||||
(note: this must be at the TOP of the path list):
|
||||
"{Compiler}:Win32-x86 Support:Headers:Win32 SDK:sys:"
|
||||
|
||||
8. Make the x86 target
|
||||
|
||||

||||
