Re: infos on compiler flag

[Paul Johnson]

That "Simple Test Program" has never compiled cleanly for me. It goes:

main.m:1:2: warning: #import is obsolete, use an #ifndef wrapper in the 
header file
main.m: In function `main':
main.m:4: warning: return type of `main' is not `int'
Printer.m:1:2: warning: #import is obsolete, use an #ifndef wrapper in 
the header file
/usr/bin/ld: warning: type and size of dynamic symbol 
`__objc_class_name_Object' are not defined


A couple of years ago I revised that so it would compile/run on my systems:

http://lark.cc.ku.edu/~pauljohn/SwarmFaq/WorkingExampleCode/Objc_HelloWorld.tar.gz

WHen I compile that, it runs, but I still get the annoying messages:

$ gcc -lobjc main.m Printer.m -o test
main.m:47:2: warning: #import is obsolete, use an #ifndef wrapper in the 
header file
Printer.m:17:2: warning: #import is obsolete, use an #ifndef wrapper in 
the header file
/usr/bin/ld: warning: type and size of dynamic symbol 
`__objc_class_name_Object' are not defined
