Hey guile users,
Trying to compile the simple example bessel.c from
Writing-Guile-Extensions.html (renamed bessel.cc because I'm using g++), I
encountered the following error:
bessel.cc: In function 'void init_bessel()':
bessel.cc:13: error: invalid conversion from 'scm_unused_struct*
(*)(scm_unused_struct*)' to 'scm_unused_struct* (*)(...)'
bessel.cc:13: error: initializing argument 5 of 'scm_unused_struct*
scm_c_define_gsubr(const char*, int, int, int, scm_unused_struct* (*)(...))'
This even comes up when I put everything in extern "C" { ... }. I have seen
other postings on the net for other software (lilypond, swig) that speaks of
the same issue, and some suggest that it is a problem with g++ and not
guile. I'm using powerpc-apple-darwin8-g++-4.0.1 (GCC) 4.0.1 (Apple
Computer, Inc. build 5370)
I know that Lilypond uses a workaround where it defines something called
GUILE_ELLIPSIS, but I am not sure how this logic can be integrated into a
small snippet of code.
Anyway, if any of you know how I can make the bessel example compile on OS X
10.4 PPC using g++ 4.0.1, I'd much appreciate it!
Cheers,
Mike
