GCC reports incorrect flags compiling descent_two_isogeny.c on Solaris 10

[drkirkby]

The build environment

• Sun T5240. 2 x 1167 MHz T2+ SPARC processors 32 GB RAM (t2.math.washington.edu)
• Solaris 10 update 6 (released in 05/2009)
• gcc 4.4.1 configured to use both the Sun assembler and linker.

sage: An error occurred while installing sage-4.3.1.alpha1 

Possible reasons

#6583 could possibly be the reason, but I am probably mistaken. The changes were committed only recently, which makes me think it might be the problem.

[drkirkby]

The last option on the gcc command line '-w' is there to suppress all warnings. (A really really bad idea IMHO). If I remove that horrid -w option, some more warnings are shown. Whether these aid in solving the problem I do not know, but they do indicate a lot of potential problems are being masked. This unfortunately is quite common in Sage, with numerous bits of code using all sorts of tricks to hide warning messages.

Based on random googling, I'd suspect the flag -std=c99, which is required since the file depends on FLINT. This thread* seems to suggest replacing that flag with -xc99. Other threads suggest adding -xc99=%none: this flag may be required because it is trying to link in ratpoints, and is the first thing in Sage to try to do so. See this thread ^{for more details.}

• - ​http://www.mathworks.com/support/solutions/en/data/1-14ZQS4/index.html?solution=1-14ZQS4

^{- ​http://mail.python.org/pipermail/python-bugs-list/2005-September/030452.html}

In particular, the relevant part of limits.h says

/*
 * It is invalid to compile an XPG3, XPG4, XPG4v2, or XPG5 application
 * using c99.  The same is true for POSIX.1-1990, POSIX.2-1992, POSIX.1b,
 * and POSIX.1c applications. Likewise, it is invalid to compile an XPG6
 * or a POSIX.1-2001 application with anything other than a c99 or later
 * compiler.  Therefore, we force an error in both cases.
 */

This is where my understanding reaches its boundaries, but maybe I've said something helpful to someone. The ratpoints code is fairly old, and it wouldn't surprise me if the above comment was relevant.

[rlm]

Actually, this could bode poorly: if ratpoints can't be compiled with c99 but FLINT must be, how to compile descent_(...).c, which depends on both?

[drkirkby]

This is really excellent news that Minh has tracked this down.

First, it should be noted that the Mathworks link published is about the Sun compiler, The compiler option -xc99=none (without the % sign), is a Sun compiler flag. I've no idea where the $ sign comes from.

This does not look as bad as perhaps Robert thinks. I need to double check this, but it would appear ratpoints will build on Solaris SPARC with -std=c99 added, so if the only issue is that, then I believe it is a trivial fix. However, if building ratpoints with this option does not allow this to work, and we can find no fix, then we are in a more serious situation.

I haven't verified this at all, but this webpage suggests that a -D_XOPEN_SOURCE=600 compile flag might be needed in some cases when using -std=c99 on Solaris: ​http://wiki.netbsd.se/index.php/Feature_test_macros

[drkirkby]

I've tried building ratpoints with

• -D_XOPEN_SOURCE=600
• -std=c99
• -std=c99 -D_XOPEN_SOURCE=600

All 3 allow ratpoints to build, but none of them allow the Sage library to build.

Ratpoints also currently builds with the option

-DUSE_SSE

on SPARC, which is a bit silly, as the SPARC processor does not support SSE instructions. Removing that (as is done on OS X already), still does not allow the Sage library to build.

Ratpoints seems to build with pretty much any options I throw at it - getting it work with the Sage library is not proving so easy.

I have not tried adding -D_XOPEN_SOURCE=600 to the Sage library. I do not know how to do this.

Dave

[wjp]

What errors do you get when building the Sage library?

[drkirkby]

The error message is shown when I created the ticket. However, you need to use the horizontal scroll facility in trac to see it, as it is on the far right.

Dave

[wjp]

Ah, I mistakenly thought that was already where you were adding the -D_XOPEN_SOURCE=600 since that was the error you reported.

The patch at #6583 adds the sage.schemes.elliptic_curves.descent_two_isogeny extension that's failing with a -std=c99 flag. (Right at the top of the patch at ​http://trac.sagemath.org/sage_trac/attachment/ticket/6583/trac_6583-rebase.patch .) That would be the place to add the extra -D_XOPEN_SOURCE=600 option (if it works...), I think.

[drkirkby]

Thanks to Jaap Spies, who found a solution on the python web site, this has been solved by a small patch to python.

The patch itself only affects Solaris, but to make double sure, you can see I only copied the patch on Solaris. So there is no fear of it breaking on any operating system.

Unfortunately, the small patch needs a revised configure.in, and a revised configure script, as well as the directory autoconf makes (sometimes copying the configure script alone is not sufficient).

As such, the Mercurial patch is 1 MB in size. I've attached it here, but you can't view it on trac due to its size.

I've also attached the smaller patch downloaded from the python web site.

All files can be found here.

I see a possible conflict between the current ticket and #7761. Ticket #7761 already has a positive review and its updated Python spkg is python-2.6.4.p6.spkg. However, the current ticket (i.e. #7867) also has an updated Python spkg python-2.6.4.p6.spkg. Is it possible for you to base your updated Python spkg on top of that at #7761?

Good catch, Minh!

Updated spkg-install to avoid clash with 7761

Patch downloaded from Python web site - date changed to today

Thank you Minh.

I've created a .p7, based on the ticket at #7761. It may be found here.

​http://boxen.math.washington.edu/home/kirkby/portability/python-2.6.4.p7/python-2.6.4.p7.spkg

I've updated all the files on this ticket.

Despite the fact patch downloaded from the Python web site is unchanged, I decided to 'touch' it to bring the date upto date, as it was previously dated much earlier. I thought it might be a bit confusing if someone looks in the patches directory. I reattached it to this ticket, which was probably unnecessary, but can do no harm. As such, it should

[jsp]

I see no problems with other architectures (tested on Fedora 11 and 12), as it only effects SunOS.

This is a great step forward on the Solaris port!

On open Solaris I now could build matplotlib for instance.

So positive review.

[drkirkby]

#8440 sorts out another issue with Python. That ticket depends on this one.
