Well, at least I feel better that I'm not crazy, (or not the only one...). Maybe if someone could give us a clue about it, we could spot where the problem is. Do you think it is a vm problem or something related to the smalltalk code? 2009/7/30 Mariano Martinez Peck <marianopeck@gmail.com>
Yes. This is really annoying for me. I am writing a C library plugin since a year and a half and this is very frustrated :( You cannot debug when using FFI. I mean, you cannot get advantages of one of the best Smalltalk features! What I do is to write a self break before and after the call and use "proceed" but I don't like it at all.
Once I tried to see what the problem was, but I was to difficult to me to understand it and fix it. We need a guru here I think hahaha.
Best,
Mariano

Hi, I'm having problems with the debugger. Every time I try to debug code that uses FFI, if I step over a message that internally does an FFI call, I get an externalCallFailed error and then I land in MethodContext(ContextPart)>>runUntilErrorOrReturnFrom: If I run the code without debugging, then I have no problems at all.
I'm using SqueakPharo v3.11.2 with pharo0.1-10373web09.07.2.
To reproduce it you can try this:
ScriptLoader loadFFI. then load latest GLMorphic from squeaksource, and uncomment the "self break." in GLCanvas>>displayString:from:to:at:strikeFont:kern:
doit World fullDrawOn: GLDisplayScreen testCanvas hit debug and step over until you reach ogl glTexImage2D: GLTexture2d with:...
also you'll see wrong values for local vars, like aPoint which will look as #(nil nil nil nil nil) when it'll actually have a point.
Is there any other way to set up a break point instead of adding self break to the code??
Thanks, Javier.
