[Scitech] Experiment with sagemath and Polybori needs to be built

[Paulo César Pereira de Andrade]

  Polybori needs to be built. In Fedora 16, essentially, this is
required to build
with current cudd-devel

polybori-0.8.1/libpolybori/include/polybori/ring/CCuddInterface.h

     }

too bad cudd.h version identifier is only a string

#define CUDD_VERSION "2.4.2"

so, probably need to write a check in

polybori-0.8.1/SConstruct

  It is also required a patch similar to this one to be able to build
sagemath with it:

http://svn.mandriva.com/viewvc/packages/cooker/polybori/current/SPECS/polybori.spec?r1=720397&r2=720396&pathrev=720397

[...]
  I am still too noob with fedora, so, I could not finish the build,
because, while I know
how to git clone a fedora package, do not know how to fetch sources.
For example,
I see easily how to clone http://pkgs.fedoraproject.org/gitweb/?p=polybori.git

but failed to finish build (did download upstream tarball) due to missing
+ tar xJf /home/pcpa/rpmbuild/SOURCES/polybori-logos.tar.xz -C
/home/pcpa/rpmbuild/BUILDROOT/polybori-0.8.1-2.fc16.x86_64/usr/share/icons/hicolor
tar (child): /home/pcpa/rpmbuild/SOURCES/polybori-logos.tar.xz: Cannot
open: No such file or directory
tar (child): Error is not recoverable: exiting now

and my guess to what to do failed also :-) Need to read more wiki
pages and check
fedpkg options for a readonly checkout, and if it can also be used to
fetch sources.

$ fedpkg clone polybori

but as stated above, it would still fail to build sagemath anyway:

Traceback (most recent call last):
  File "./setup.py", line 18, in <module>
    from module_list import ext_modules
  File "/home/pcpa/rpmbuild/BUILD/sage-4.8/spkg/build/sage-4.8/module_list.py",

    for line in open(SAGE_LOCAL + "/share/polybori/flags.conf"):

'/home/pcpa/rpmbuild/BUILDROOT/sagemath-4.8-0.1.x86_64/usr/share/sagemath/local/share/polybori/flags.conf'

[...]
  Just so that it should be easy to reproduce what I did tonight in a
quick check of "how deep the water is", and initial adaptation of my
Mandriva sagemath spec, I will attach the spec and patches.

  So far, mpir is not packaged in Mandriva, and besides sagemath, I also patched
Macaulay2 to not hardcode mpir dependency also, and use gmp5.

  The patch to use unpatched ntl should have a nasty side effect in the notebook
because it will miss the error message, if in the terminal, it will
print the error message
to stderr anyway before calling abort. But really, it should have been sagemath
to convince upstream NTL for the need of a more complete api.

Thanks,
Paulo
