[Debian-science-sagemath] Sagemath Build-Depends backported - unfortunately build error (Was: Help needed to backport ipywidgets ... (Was: Backporting sagemath))

[Tobias Hansen]

Hi,

how are you building the package, with sbuild?

It looks like the stuff in debian/pruner did not find fplll and sage is
trying to build its own version. If you change the distribution in the
changelog to something else than UNRELEASED it will abort earlier, after
outputting "XXX will not come from Debian". (The XXX should be 0.)

The check for fplll is in debian/pruner/configure.ac:

AC_LANG_PUSH([C++])
AC_CHECK_HEADER(fplll/fplll.h, HAS_FPLLL="True", HAS_FPLLL="False")
AC_LANG_POP([C++])

That sage tries to build its own packages can also happen if you are
building without the Debian patches applied for some reason.

Anyway, it would be good to see more of the log.

Best,
Tobias
