Comment:
After a little more tweaking and temporarily disabling the extension
fields/rings,
I was able to build some parts of sage with Singular 4.0.1 on a 'fc18
system' and
then.. sage crashes at start! That happens because I didn't update ring
creation right - I only recently discovered examples at
'./libpolys/tests/rings_test.h'. And some sage packages create common
rings at loading time.
remaining riddles:
- during build one sage file tried to link to -lsingular (I have no idea
why), instead to the libSingular* files (that changed!), so I worked
around by manually creating links to libSingular* files.
- on a ScientificLinux system I get errors like "ImportError:
/home/kroeker/Projects/sage-singular-4.0.1/local/lib/python2.7/site-
packages/sage/rings/polynomial/plural.so: undefined symbol:
wFunctionalBuch". This symbol is in libSingular*
- fix ring creation. See examples at './libpolys/tests/rings_test.h'
- the extension fields will need some more love. See 'algext.h' and
'transext.h'. @Martin: could you take a look?
- some mapping functions (e.g. nr2mMapZp) now require a source and dst
(coefficient) parameter. Not sure if I did it right (source: currentRing,
dest: _ring or vice versa?)
- I didn't fix unused interface definitions in singular-cdefs.pxi. TODO
See branch u/jakobkroeker/ticket/17254
and some notes at https://github.com/jakobkroeker/jk_test_sage/issues/13
If a build get stuck before errors described above, then maybe a 'make
distclean' is necessary.
And of course, the Singular tarball
http://boxen.math.washington.edu/home/jdemeyer/spkg/singular-4.0.1p1.tar.bz2
is required.
Any help appreciated.
