Objective-C Programming

Objective-C is a set of object-oriented additions to ANSI C; much cleaner than C++. It is supported by GNU GCC compiler, as well as the Apple compiler that ships with Mac OS X. Objective-C is the best-supported way of programming for that OS.

GNUstep on SGI IRIX

Notes from installing GNUstep base on SGI IRIX 6.5:

• Downloaded GNUstep make 1.3.0
• Downloaded GNUstep base 1.3.0
• Made directory /usr/local/gnustep
• In GNUstep make distribution did

  ./configure --prefix=/usr/local/gnustep
  make
  make install

• In GNUstep base distribution did

  setenv GNUSTEP_SYSTEM_ROOT /usr/local/gnustep/System
  ./configure
  source $GNUSTEP_SYSTEM_ROOT/Makefiles/GNUstep.csh
  make
  make install

  • got warning about mframe not having been ported to IRIX
  • GNUmake crashed; needed to make /Source/Additions/static_obj/mips/irix6.5/gnu-gnu-gnu/subproject.o out of the object files in that directory using ar cr subproject.o GS*.o.
  • Compiling autogsdoc failed; needed to repeat that command line(s) adding the above subproject.o to the mix.
