python fails to build _socket on OpenSolaris x64, so ipython fails to build.

[drkirkby]

Build environment

• Sun Ultra 27 3.33 GHz Intel W3580 Xeon. Quad core. 8 threads. 12 GB RAM
• OpenSolaris 2009.06 snv_111b X86
• Sage 4.4.2
• gcc 4.4.4

How gcc 4.4.4 was configured

Since the configuration of gcc is fairly critical on OpenSolaris, here's how it was built.

drkirkby@hawk:~/sage-4.4.2$ gcc -v
Using built-in specs.
Target: i386-pc-solaris2.11
Configured with: ../gcc-4.4.4/configure --prefix=/usr/local/gcc-4.4.4 --with-as=/usr/local/binutils-2.20/bin/as --with-ld=/usr/ccs/bin/ld --with-gmp=/usr/local --with-mpfr=/usr/local
Thread model: posix
gcc version 4.4.4 (GCC) 

gcc 4.3.4 was failing to build iconv.

How the Sage build was attempted

• 64-bit build. SAGE64 was set to "yes"
• #9008 update zlib to latest upstream release to allow a 64-bit library to be built.
• #9009 update mercurial spkg to build 64-bit.
• #7982 update sage_fortran so it can build 64-bit binaries.
• 'touch' spkg/installed/gdmodule-0.56.p7 to fool Sage into thinking gdmodule had installed, as it is failing to (see #9021)

The problem

One can see that _socket is not being built:

building '_ssl' extension

This is shown later when the list of failed modules is displayed in the Sage build log.

Failed to build these modules:
_curses            _curses_panel      _socket
_ssl               _tkinter           sunaudiodev

This then causes ipython to fail to build.

Likely hints as to the cause

The following couple of links have something written about the _socket issue:

• ​http://www.opensolaris.org/jive/thread.jspa?threadID=5426&tstart=0
• ​http://www.lotuseyes.de/blog/error-installing-plone-on-opensolaris-using-the-unified-installer

As of this minute, I don't have a solution for this.

The solution proposed at

​http://www.lotuseyes.de/blog/error-installing-plone-on-opensolaris-using-the-unified-installer

may be workable, though I would restrict the patch to just OpenSolaris, not just any Solaris release, which is what suspect his

#if defined(__sun)
#  define ifr_ifindex ifr_index
#  undef HAVE_NETPACKET_PACKET_H
#endif

will do.

For other OpenSolaris issues, see #9026

[drkirkby]

I've reported this as a bug.

​http://bugs.python.org/issue8852

and have received some feedback, though it is not yet acknowledged as a bug or not.

The failure of _socket to build is also causing pygments to fail to build - see #9041. Once I've produced a patch, hopefully both ipython and pygments will build ok.

Dave

[drkirkby]

The fix for this is the same as required for #9041. So please review #9041. The changes have been tested on

• Linux
• OS X
• OpenSolaris on x64 (where the problem occured)
• Solaris 10 on SPARC

See all the supporting evidence at #9041.

Notes to the release manager

This ticket may be closed when #9041 is closed.

See #9041

[drkirkby]

I would also see #9295, which is an improvement on #9041, adding the facility to check Python by adding an spkg-check file.
