Try (note you need to add 4, to get to the next string)
PChar(^LONGINT(^LONGINT(@t)^+0)^)
PChar(^LONGINT(^LONGINT(@t)^+4)^)
PChar(^LONGINT(^LONGINT(@t)^+8)^)
and for the length of array (minus 4)
^LONGINT(^LONGINT(@t)^-4)^

(just strings are a pointer them self, so they need one level more)

(updated)
If that doesn't help, then it wont work. (or i don't know how)
Problem is that the debugger doesn't understand the pascal concept. so
you unfortunately need a lot of understanding, of how fpc encodes your
data, what is a pointer, what is which kind of record....
It is improving in 2.3.1 (and maybe even more with dwarf).
If nothing helps:
LCLProc.debugln
writeln

Thanks Silvio,
I'm not having a problem a problem with code running. I'm not able to
Inspect the contents of VStringArray while debugging via GDB in
Ubuntu.
Can you inspect the variable VStringArray? How about VStringArray[0]?
I can not.
This is a fresh build of FPC and Lazarus from TRUNK and a BRAND new
install of Ubuntu 9.04.
There a various problems, like this. It is an issue between fpc and
gdb.
A lot may depend on the version of fpc and the version of gdb you use.
A few thinks you can try, but I don't know if they will work for you.
Try Dwarf versu stabs (Compiler option in Lazarus), Tab: Linking
While debugging the following has worked for me under window (not sure
if I used dwarf, I think not). And it only worked if there was an
explicit type:
type TStringArray = Array of String; var a: TStringArray
but not for
var a: Array of String;
instead of
a[0]
I wrote (in the watch window)
a^[0]
Martin, thanks for the strength ;-) .
With I showed, had no errors. I'm using now the following (see pictures):
GDB - [http://www.4shared.com/file/122487107/bfb46cfd/gdb.html].
Lazarus - [http://www.4shared.com/file/122487336/e01adbc6/lazarus.html].
ps. Friends, I don't know much English but I try to help somehow. :-)
