gh_new_procedure with c++

[gianluca giorgolo <giorghy@yahoo.it>]

Hi,

I'm sorry if the question has already been answered on the list but I couldn't find any reference to the topic in the archive (nor in guile user manual).

I'm trying to use 'gh_new_procedure' to define a new procedure for Scheme that refers to a c++ function. This function takes more than 0 arguments. But given that the gh_new_procedure is defined as taking a function with no argument, g++ complains about the invalid conversion:

main.cpp:131: error: invalid conversion from ‘scm_unused_struct* (*)(scm_unused_struct*, scm_unused_struct*, scm_unused_struct*, scm_unused_struct*, scm_unused_struct*)’ to ‘scm_unused_struct* (*)()’
main.cpp:131: error:   initializing argument 2 of ‘scm_unused_struct* gh_new_procedure(const char*, scm_unused_struct* (*)(), int, int, int)’

(I'm using guile 1.8.1 and gcc 4.1.3)

Is there any way to avoid the type conversion that apparently g++ doesn't like?

Thanks a lot in advance for any reply!

Gianluca
