| Description: |
Solaris Intel 10 supports 64-bit programs as well as Solaris sparc do. While GCC provided by sunfreeware or cleanly build from sources doesn't enable 64-bit mode by default, Sun provides package SUNWgcc, which contains patched gcc 3.4.6, which supports 64-bit mode. However, Tcl configure doesn't know about ability to build 64-bit version of Tcl on Solaris Intel 10 (and above) platform. It explicitely test for output of Solaris isainfo utility to be equal to "sparcv9 sparc", while "amd64 i386" is 64-bit platform as well. Attached patch made against configure script of tcl8.4.18 fixes this problem (problem still exists in tcl8.5.6) | |||

It was previously set to a Pending status, and the original submitter did not respond within 14 days (the time period specified by the administrator of this Tracker). das added on 2009-04-10 01:59:36: it is certainly very possible that it is only a matter of adjusting the glob pattern to also match 5.10 in my patch to get support for that release, I would have only enabled my changes on the earliest solaris version I had easy access to at the time, for fear of breaking something on earlier releases... dgp added on 2009-04-10 01:20:40: The Steffen patch supports 64 bit builds on arch "amd64 i386" running SunOS-5.11 or higher, it appears. Is the bug here that it is possible to support SunOS-5.10 as well? dgp added on 2009-04-10 01:14:06: We cannot use the contributed patch. It patches "configure" which is a generated file. We would need a corrsponding patch for configure.in and tcl.m4, the sources from which configure is generated. Our development logs show: 2008-06-12 Daniel Steffen <[email protected]>... * unix/tcl.m4 (SunOS-5.11): fix 64bit amd64 support with gcc & Sun cc. * unix/configure: autoconf-2.59 so we would expect things to work properly starting with release Tcl 8.5.3, yet you report failure for either 8.5.5 or 8.5.6 (not clear). Please give the 8.5.6 release another check, and if it is failing, see what details you can offer for why the Steffen commit didn't take care of things for you. andreas_kupries added on 2009-04-07 06:08:56: Ok, this patch seems to be out of date.
Looking at the tcl.m4 file of all Tcl branch heads I find that the check for 'sparcv9 sparc' is always followed by a check for 'amd64 i386' which does what the patch purports to be doing, as far as I can tell.
8.4: line 1871 - sparc check
line 1894 - amd64 check
8.5: line 1901 - sparc
line 1923 - amd64
8.6: line 1878 - sparc
line 1900 - amd64
Contrary to what I said on the chat I was unable to fully test the patch on our build box, because the gcc we have on that box is apparently not 64bit enabled. I might be able to install the patched SUNWgcc, not today anymore however.
I was able to check the native compiler
The unpatched sources are generating proper 64bit executables.
The patched sources don't.
