Porting Python to the open source realtime OS called RTEMS I get a compile error on line 2797 of socketmodule.c.=20 =20 =20 In my copy, this is the line =20 char packed[MAX(sizeof(struct inaddr), sizeof(struct in6addr))]; ^^ I would assume the marked code is for IPV6 so needs to be protected by=20 ENABLE_IPV6, for example:

#ifdef ENABLE_IPV6 char packed[MAX(sizeof(struct in_addr), sizeof(struct in6_addr))]; #else char packed[sizeof(struct in_addr)]; #endif

=20 Can you report more on the nature of the compile error (such as its message)? =20

(I do not use the Python build system as I have to cross-compile and so u= se an=20 automake makefile in a RISCOS type layout)

Sure. The output is from gcc-3.2.3:

Should this code check ENABLEIPV6 as IPV6 is not support on RTEMS yet.=

=20 =20 (assuming this is a question): I'm unsure. It should not cause a compile time failure, period. =20

Sorry, it was a question. See above.

=20

Also where is INETADDRSTRLEN suppose to be defined ? =20 <netinet/in.h> =20

Thanks. The RTEMS TCP/IP stack is an old port of the FreeBSD stack and do= es not=20 have this. The current FreeBSD does so I will fix RTEMS. I will not add=20 INET6_ADDRSTRLEN as no other IPV6 support is currently provided.
