# This script reads the contents of Versions.all and outputs a definition
|

|
|
# of variable have-VERSION for each symbol version VERSION which is
|
||
|
|
# defined.
|
||
|
|
#
|
||
|
|
# The have-VERSION variables can be used to check that a port supports a
|
||
|
|
# particular symbol version in makefiles due to its base version. A test
|
||
|
|
# for a compatibility symbol which was superseded with a GLIBC_2.15
|
||
|
|
# version could be tested like this:
|
||
|
|
#
|
||
|
|
# ifdef HAVE-GLIBC_2.14
|
||
|
|
# tests += tst-spawn4-compat
|
||
|
|
# endif # HAVE-GLIBC_2.14
|
||
|
|
#
|
||
|
|
# (NB: GLIBC_2.14 is the symbol version that immediately precedes
|
||
|
|
# GLIBC_2.15.)
