automake: Objective C Support

1 
1 8.10 Objective C Support
1 ========================
1 
1 Automake includes some support for Objective C.
1 
1    Any package including Objective C code must define the output
1 variable ‘OBJC’ in ‘configure.ac’; the simplest way to do this is to use
11 the ‘AC_PROG_OBJC’ macro (⇒Particular Program Checks
 (autoconf)Particular Programs.).
1 
1    A few additional variables are defined when an Objective C source
1 file is seen:
1 
1 ‘OBJC’
1      The name of the Objective C compiler.
1 
1 ‘OBJCFLAGS’
1      Any flags to pass to the Objective C compiler.
1 
1 ‘AM_OBJCFLAGS’
1      The maintainer’s variant of ‘OBJCFLAGS’.
1 
1 ‘OBJCCOMPILE’
1      The command used to actually compile an Objective C source file.
1      The file name is appended to form the complete command line.
1 
1 ‘OBJCLINK’
1      The command used to actually link an Objective C program.
