[Reasonablepy-users] Question regarding compiling reasonablepython.

[Andrew J. D. <and...@fr...>]

To whom it may concern,

I am working on a Perl interface for Flora-2. Given that I'm not 
familiar enough with C++ or SWIG, I decided to write an Inline::Python 
wrapper for ReasonablePython. I was wondering if this project is still 
going?

When I try to compile it on amd64, I get some errors. After tweaking 
with the location of the XSB .h files,


------------------------

# platform = 'i686-pc-linux-gnu-deb'
platform = 'x86_64-unknown-linux-gnu'

------------------------


I get a lot of conflicting type errors regarding ptoc_int and ctop_int 
and other such wrapper functions.


------------------------

In file included from rp/xsb_swig/swig_xsb_wrap.c:2346:0:
rp/xsb_swig/swig_xsb.h:48:13: error: conflicting types for ‘ptoc_int’
extern int ptoc_int(int);

‘ptoc_int’ was here

^
In file included from rp/xsb_swig/swig_xsb_wrap.c:2346:0:
rp/xsb_swig/swig_xsb.h:58:15: error: conflicting types for ‘ctop_int’

------------------------


So at first I tried to remove the "conflicting" definitions by removing 
the "extern ..." declarations in xsb_swig.{c,h}. Then it compiles, but 
when loading it with interface, it segfaults.

 >>> >>> from rp import *
 >>> f = interface.Flora2();
Segmentation fault

------------------------


I also tried "correcting" the extern declarations to the ones from the 
latest xsb swig, but that also compiles then segfaults.
