[cells-gtk-devel] Re: Comments II for "First steps" how to

[Peter Hildebrandt]

Friedrich,

I take your feedback very seriously.  I started from scratch with a 
fresh sbcl config (on ubuntu 7.10) and went step by step through the 
guide.  I found a number of typos/inconsistencies which are all fixed 
now.  For me, thinks work perfectly now.

So let us try to track down what is different for you and how we can 
handle those cases.

For me the current makefile is fine.  I am not a C programmer, so what 
does -fPIC do?  I see you removed glib from the pkg-config command. 
gtk-adds.c includes glib -- does that make a difference?

My gcc is "gcc (GCC) 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)".

You are using a non-supported version of cffi.  Try the latest version 
(not the darcs tree) from the cffi project page.  I describe this in 
more detail in my guide.

Current work is on making cells-gtk work with the latest Cells, so there 
are no resources to work on CFFI right now, especially since cells-gtk 
works with the latest release.
