[linux-minidisc] Building himdformat against libscg on MacOSX

[Adrian Glaubitz <glaubitz@physik.fu-berlin.de>]

Hi,

after several nervous breakdowns, I finally managed to build
himdformat on MacOS against libscg as included in cdrtools.

Eventually, it only took a few hacks to get it compile. I didn't test
the functionality yet (due to lack of hardware right now). So, here's
what I did:

1) Install cdrtools from Macports:

   port install cdrtools

2) Apply the supplied patch "0001-cdrtools-darwin-xconfig.patch" to
   /opt/local/include/schily/xconfig.h.

3) Create a symbolic link to CoreFoundation dynamic linker library in
   the current directory (see [1]):

   ln -s /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation libcorefoundation.dylib

4) Compile himdformat.c with:

   gcc -D__DARWIN_X86_CC32 -I/opt/local/include -L/opt/local/lib -L. -lcorefoundation -lIOKit -lschily -lscg -o himdformat_scg himdformat_scg.c
   
5) himdformat runs on MacOS:

   minimac2:~ zedv$ ./himdformat_scg 
   Please specify the path to the scsi device
   minimac2:~ zedv$

I'm attaching the libscg version of himdformat as well as the
necessary patch.
