7.4.1 Cache Variable Names
The names of cache variables should have the following format:
for example, `ac_cv_header_stat_broken' or
`ac_cv_prog_gcc_traditional'. The parts of the variable name are:
- An abbreviation for your package or organization; the same prefix you
begin local Autoconf macros with, except lowercase by convention.
For cache values used by the distributed Autoconf macros, this value is
- Indicates that this shell variable is a cache value. This string
must be present in the variable name, including the leading
- A convention for classifying cache values, to produce a rational naming
system. The values used in Autoconf are listed in Macro Names.
- Which member of the class of cache values this test applies to.
For example, which function (`alloca'), program (`gcc'), or
output variable (`INSTALL').
- Any particular behavior of the specific member that this test applies to.
For example, `broken' or `set'. This part of the name may
be omitted if it does not apply.
The values assigned to cache variables may not contain newlines.
Usually, their values are Boolean (`yes' or `no') or the
names of files or functions; so this is not an important restriction.
