|
|
+dnl MINIMUN-VERSION is a string with the version number optionalliy prefixed
|
|
+dnl with the API version to also check the API compatibility. Example:
|
|
+dnl a MINIMUN-VERSION of 1:1.2.5 won't pass the test unless the installed
|
|
+dnl version of libgcrypt is at least 1.2.5 *and* the API number is 1. Using
|
|
+dnl this features allows to prevent build against newer versions of libgcrypt
|
|
+dnl with a changed API.
