Hi all,
I'm trying to write a Guile/C RPC client (I know about guile-rpc but would
like to get this working also).
The dir.x and server code is the standard RPC example. I have only
modified the client (code below).
It works fine as far as the xdr_free at the bottom, which causes a
segmentation
Hi all,

Not sure what you are having problems with, but this produces a PDF:

Hi all,
In a Guile program I am using (system ) to start a C binary
which I then communicate with over the network.
I'm wondering if there is any way to get the process id of this binary?

Hi all,
I am trying to change a colour to transparent by doing this:
(gdk-pixbuf-add-alpha img #t (integer->char r) (integer->char g)
(integer->char b))
(Doing `interger->char' seems a bit weird but passing ints causes
errors.)
However, the image is not changed (I write it out using

Hi all,
I'm trying to create a Guile module, using code written in Mercury.
(http://www.cs.mu.oz.au/research/mercury/)
I have managed to produce a library file (.so), but when I try to open
it in Guile (with dynamic-link), I get "file not found". It's clear from
the strace output that it does find

It should be this bit I think:

Hello again everybody,
After some experimentation, it now seems clear that this has nothing
to do with garbage collection or Mercury. It is probably just a silly
programming error on my part.

the problem I am having. The importan

Hello one more time,
There was a little problem in mytest.c, where I had declared a pointer

fault.
With the following source files, the code Linas posted, after some
modifications, is compiled to a binary `vepstas' which runs fi

Well, since the `vepstas' binary works, the Mercury bit seems ok.
Do you have any suggestions for how to

Hi all,
After upgrading to Guile 2.0.1, my Mercury - Guile app stopped working.

Hi all,
I have an extended Guile interpreter with a C function "get-map",
defined by "scm_c_define_gsubr", that I then try to use in the
(pure Scheme) module "mapdisplay", with the following result:

It's in the top-level module.
