Dear Kent, cc Syfi/Instant developers

ok, yes i'm also confused that the cln/include-path gets lost although, 
the pkg-config knows about it. anyhow it could fix that with the 
workaround i described.

as sfc uses python2.5 and instant as well, i now readjusted my whole 
stuff and turned to python2.5. the other packages of fenics (fiat, ffc, 
ferari and ufc do well with python2.5)

the problems now remain with the creation of the syfi-module and the 
'just-in-time' compiling with instant.

1)
in the case of SyFi, the gcc-compiler and swig is used to build the 
"SyFi_wrap.cxx", which fails with the following output:

2) i have similar problems with instant, which i could install for 
python2.5, but when running some test examples the compiling always 
fails with e.g.

In instant.recompile: The module did not compile, see 
'/tmp/tmp7XWixt2008-12-2-10-15_instant/instant_module_5bc73bd961e29c451f59fef5a2f1ebe9ff034456/compile.log'

and in the compile.log i then find

i suppose there is a problem with swig and gcc?
what i have used for my configuration is the following:

- ginac-1.4.4 (and cln, both compiled with gcc4.2.2)
- gcc-4.2.2
- python-2.5
- swig-1.3.29

and this i do on a amd64-debian-linux4.0 (etch).

could you tell me about a possible configuration which should work in 
your view?


thanks for your help and best regards
patrick
