Re: infos on compiler flag

[Paul Johnson]

I don't know what what you are referring to by "my" flags.  The gcc guys 
just say to add the flag -fgnu-runtime.

Looking in the main.m file in the Obj-C hello world package I mentioned 
earlier, I am reminded that I provide the gcc command:

 gcc -o test  -Wno-import main.m Printer.m -lobjc -lpthread

I have no trouble compiling the program if I add -fgnu-runtime in there.

$ gcc3 -o test -Wno-import -fgnu-runtime main.m Printer.m -lobjc -lpthread

results in a working program for me. The -lpthread option is not 
required on my system, but it is necessary for gcc-2.95.
