>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Core/BuildSystem
>    Affects Versions: 13.6.0
>            Reporter: John Nemeth
>            Severity: Minor
>              Labels: patch
>      Target Release: 13.21.0, 15.4.0

> configure.ac has the following (checked gitweb and trunk has the same):
> # Find required UUID support.
> #  * -luuid on Linux
> #  * -le2fs-uuid on OpenBSD
> #  * in libsystem on OS X
> AST_EXT_LIB_CHECK([LIBUUID], [uuid], [uuid_generate_random], [uuid/uuid.h], [])
> AST_EXT_LIB_CHECK([E2FSUUID], [e2fs-uuid], [uuid_generate_random], [uuid/uuid.h]
> , [])
> AC_CHECK_FUNCS([uuid_generate_random], [SYSUUID=true], [SYSUUID=""])
> On my system (NetBSD with libuuid package installed), the first test returns "yes", and the rest return "no":
> checking for uuid_generate_random in -luuid... yes
> checking uuid/uuid.h usability... yes
> checking uuid/uuid.h presence... yes
> checking for uuid/uuid.h... yes
> checking for uuid_generate_random in -le2fs-uuid... no
> checking for uuid_generate_random... no
> The problem is that the result of the later tests overwrite the results of the earlier test.  Thus the final answer is "no", even though it should be "yes".
> I have marked this bug as "minor" because the test result isn't actually used.  This could be considered to be a seperate bug, i.e. the result should be used, or the test should be eliminated.
