Toolchain

Note: This page is outdated. Please check the main Solaris bit porting page for the current status.

Sage 3.1.3.alpha1 ought to build on SkyNet using the toolchain provided by mabshoff. To use that toolchain run

on Fulvia. The Sparc build is still broken. While Sage 3.1.3.alpha0 is out it is still broken in a couple of places, but alpha1 will contain fixes for

Failed Doctests

Ironically the doctest devel/sage/sage/gsl/ode.pyx times out, i.e. it takes roughly ten times as long on Solaris as it does on the same hardware under Linux.

A good simple example:

sage: PolynomialRing(GF(127),9,names='x')._singular_()
[hang]

Oddly putting 8 instead of 9 and it works...

In fact, essentially *ANY* long line breaks the interface.

Indeed - the following works fine under Singular itself (note that the prompt for Singular has been changed to "@"):

The problem is not caused by (a) a limited stack since increasing it to 512kb still hangs or (b) a compiler issue since Singular compiled with "-O0" still hangs. All fingers point to pexpect

------------------------------------------------------------
Unhandled SIGSEGV: A segmentation fault occured in SAGE.
This probably occured because a *compiled* component
of SAGE has a bug in it (typically accessing invalid memory)
or is not properly wrapped with _sig_on, _sig_off.
You might want to run SAGE under gdb with 'sage -gdb' to debug this.
SAGE will now terminate (sorry).

The fix here is to do something similar as on OSX, i.e. "top -b -n 300" returns 300 processes in a non-interactive session. The following patch fixes the problem:

After the patch gen.pyx crashes on exit after running out of 2GB address space *after* all tests have passed. top reports the memory usage rising whn Python is exiting:
