Greetings ~
I'm trying to obtain the system version and although my test program executes "Gestalt(gestaltSystemVersion, (SInt32*)MacVersion)" correctly, it crashes inside my actual code:
(gdb) run -exe
Starting program: /stage/ino/bin/InoRpc -exe
[Switching to process 16740 thread 0xb03]

Cannot access memory at address 0x0

#4 0x9026bcf4 in read_property_list ()
#5 0x9027974c in read_parse_system_version ()
#6 0x90279878 in _Gestalt_SystemVersion ()
#7 0x90279924 in InvokeSelectorFunctionUPP ()
#8 0x9023c684 in Gestalt ()
#9.....continues into my code
I don't have the source code for any of these factions so I'm at a dead-end as far as debugging is concerned. I even tried making a wrapper function to Gestalt and placing it in its own library. The problem is all of our code is windows-based ported to Unix and now being ported to Macintosh. So we have avoided using apple frameworks until now.
Can anyone lead me in the right direction as to how I can debug this? If not, is there a way to build a library that will be completely independent of the application that links to it? If not, can you suggest an alternate way of obtaining the operating system version?
Thanks in advance,
~ Chris
