p5.22-socket6 0.270 does not build on PPC Mac OS X 10.4.11, Tiger

The failure is:

I reported that case to bug-Socket6 [at] rt.cpan.org, as mentioned on ​https://rt.cpan.org/Public/Bug/Report.html?Queue=Socket6.

The build error can be resolved by commenting out the definition of inet_ntop in the inet_ntop.c file, and relying on the definition in /usr/include/arpa/inet.h

This is an important issue, because it is a dependency for installation of git.

[ballapete (Peter "Pete" Dyballa)]

Replying to phillip.stevens@…:

The build error can be resolved by commenting out the definition of inet_ntop in the inet_ntop.c file, and relying on the definition in /usr/include/arpa/inet.h

Yes, that would be a work-around.

Looking a bit closer at the case Socket6.xs has:

   99	#ifndef HAVE_INET_NTOP
  100	#include "inet_ntop.c"
  101	#define	HAVE_INET_NTOP		1
  102	#endif
  103	#ifndef HAVE_INET_PTON
  104	#include "inet_pton.c"
  105	#define	HAVE_INET_PTON		1
  106	#endif

So it has to do with configure. Config.log has:

So it has to do with the test programme here that net_ntop.c gets included, because this test programme fails to run correctly. There do not seem particular (environment) variables to be set. So using that test programme I tried to compile it manually with additional diagnostic output:

The binary built is:

and when invoked it fails (it is a tcsh I am using):

root 243 /\ ./conftest 
root 244 /\ echo $status
1

I cannot judge what's wrong here…

Assuming that PPC Tiger has an IPv6 compatible implementation of inet_ntop() one could simply patch Socket6.xs to not contain these three lines:

  100	#include "inet_ntop.c"
  101	#define	HAVE_INET_NTOP		1
  102	#endif
}}

Some IPv6 support seems to exist in PPC, according to `configure`:

{{{
checking whether you have sin6_scope_id in struct sockaddr_in6... yes
}}}

Andrew Gallante sent a patch which solves the problem in Tiger. (I corrected the paths to make them fit.)

[dbevans (David B. Evans)]

According to your upstream ticket, this issue was fixed in p5-socket6 version 0.28 which was committed in r150089 a few days ago. Please verify that your Tiger issue has been resolved and that this ticket can be closed.

[dbevans (David B. Evans)]

With no further reply, assuming that this issue is resolved.
