[PD] pd externals load/unload

[alberto.zin at poste.it]

Hi Thomas,

Your answers raised me one more (simple?) question: 
If I want to load the whole PD exec in the debugger 
I imagine that PD must be compiled with the "debug" flag 
(-g for gcc) activated, am I correct? 
At the moment I didn't try to compile  
PD from the sources yet (I use the H.C.S. extended
precompiled version on both Linux and WinXP, 
that I don't think are compiled with -g ...)

Thanks, 

Alberto

it won't crash pd, because once an object (with a certain
name) is  
loaded, it won't be loaded again in the same session. The
code stays  
active until you restart pd. The OS will decide if you can
replace  
the binary file of the external object in use. I think Windows  
doesn't allow that.

you can use -verbose to see the search order. I think the
one in the  
patcher dir is loaded first, but i'm just guessing....

greetings,
Thomas
