SyFi fails to build with SWIG 2.0.4

[Johannes Ring]

When trying to build SyFi with the latest SWIG (2.0.4), I'm running into the following error:

[ 96%] Building CXX object syfi/swig/CMakeFiles/_SyFi.dir/SyFiPYTHON_wrap.cxx.o

Any ideas?

SWIG 2.0.4 is in Debian unstable (and the next Ubuntu) and I am therefore unable to build SyFi there at the moment.

[Kent-Andre Mardal (kent-and)]

Strange, this is code generated by swig itself. The asdict function is
never used in our interface file. Are you sure the wrapper file is generated
by
the installed swig ?

Yes, I'm sure.

I just tried with the development version of SWIG and it seems that this problem was introduced by the commit in revision 12659 (probably in std_map.i):

  http://swig.svn.sourceforge.net/viewvc/swig?view=revision&revision=12659

SyFi builds fine when I revert back to revision 12658. Is this a bug in SWIG or is there anything we can do in SyFi to fix this?

BTW, I have the same problem with swiginac.

[Johannes Ring (johannr)]

This bug is stopping me from fixing Debian bug #629564. I will therefore remove syfi from the fenics package in Debian until this is fixed (either in SWIG or in SyFi).

[Johannes Ring (johannr)]

This turned out to be a bug in SWIG, see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=633710.
