Thanks to everybody. At the end it was the problem Michael said. /usr/local/bin/squeak was just a script but the executable was in <br><br>/usr/local/lib/squeak/3.11.13-2135/squeakvm<br><br>Now it works perfect. I can gdb the Squeak VM!!<br>
<br>Thanks a lot.<br><br>Mariano<br><br><div class="gmail_quote">On Sun, Mar 28, 2010 at 10:04 PM, Eliot Miranda <span dir="ltr"><<a href="mailto:eliot.miranda@gmail.com">eliot.miranda@gmail.com</a>></span> wrote:<br>

Also, a tip: if you're making VMs, it's better not to install them in<br>
/usr/local until you're happy with them being stable and working. Use:<br>
<br>
> ../unix/cmake/configure --CFLAGS="-g3 -pthread" --LIBS=-lpthread --prefix=~/Pharo/myvm (or something).<br>
> nice make install<br>
<br>
(I assume the configure script takes --prefix like GNU autoconf does?)<br>
<br>
Also, if you just want to see how the interpreter works, you can run<br>
it inside Squeak:<br>
