[SR-Users] WORDS_BIGENDIAN error in auth_diameter.h

[Sotas Development]

Hello All,

We are currently cross compiling Kamailio for powerpc and are encountering
an "issue", of which we want to know whether or not it is intentional. In
the modules/auth_diameter/diameter_msg.h of Kamailio 4.0.4 (latest) we
found the following line:

72:     #error BIG endian detected!!

But it looks like if all the code is in place to make big endian function
as desired. Is this a leftover debug message? The reason we are asking is
because we previously encountered another error with a similar check for
WORDS_BIGENDIAN, in MD5.h.

It appears as the check is built in on multiple places for this
preprocessor directive, however it is not set anywhere. Are we missing a
necessary build step somewhere?
We have solved the issue for now by patching the diameter_msg.h to remove
the #error statement, and start the makefile using:
CC_EXTRA_OPTS = "-DWORDS_BIGENDIAN"

This seems to solve our initial issue, which was an md5 mismatch on
authentication, however we are still unsure if this is a proper workaround,
or if we are missing something else. It would be very nice if someone could
shed some light on this.

Thanks in advance,


Sotas Team
(Pascal, Yuri).
