[Chicken-users] swig and c++ and stuff
I tried a big SWIG wrap on part of a C++ library. This generated a .cxx wrap file and a .scm file. The build sequence I'm using is this: $(CHICKEN) tvision.scm -output-file otvision.c $(CXX) --shared otvision.c tvision_wrap.cxx -o tvision.so `rhtv-config --include` `rhtv-config --cppflags` `rhtv-config --dir-libs` `rhtv-config --dlibs` -lchicken This seems to build to a tvision.so file, but when I install that and (use tvision), I get this: ersion 2.524 - linux-unix-gnu-x86 - [ libffi dload ptables applyhook cmake ] (c)2000-2007 Felix L. Winkelmann ; loading /home/me/.csirc ... ; loading /usr/local/lib/chicken/1/readline.so ... ; loading library regex ... #;1 (use tvision) ; loading /usr/local/lib/chicken/1/tvision.so ...

Is this a common problem? If so, what have I done wrong? ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users

What version of SWIG are you using? I've seen this problem with versions prior to 1.3.29. -Ivan Tony Sidaway [EMAIL PROTECTED] writes: I tried a big SWIG wrap on part of a C++ library.

Check the _wrap.cxx file and the binaries with nm (and c++filt genRefs() only appears as a friend function in the class prototypes; it isn't implemented so it doesn't belong in the wrap. I removed it and another class function that wasn't implemented, and now it loads fine. I can use the introspection procedures of tinyclos to look at the slots and methods. I suspect that any remaining problems are due to my inexperience with tinyclos. ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
