automake: Conditionals
1
1 20 Conditionals
1 ***************
1
1 Automake supports a simple type of conditionals.
1
1 These conditionals are not the same as conditionals in GNU Make.
1 Automake conditionals are checked at configure time by the ‘configure’
1 script, and affect the translation from ‘Makefile.in’ to ‘Makefile’.
1 They are based on options passed to ‘configure’ and on results that
1 ‘configure’ has discovered about the host system. GNU Make conditionals
1 are checked at ‘make’ time, and are based on variables passed to the
1 make program or defined in the ‘Makefile’.
1
1 Automake conditionals will work with any make program.
