I'm trying to set a condition on a breakpoint.
I have a local variable aUnit, type string:
var
aUnit : string;
I wish the breakpoint is only triggered when aUnit equals 'termio'.
So, in the breakpoint properties dialog, I enter the condition:
aUnit='termio'
It seems to have no effect whatsoever. The breakpoint is triggered
always at
the first traversal of the line.
I tried variations (uppercase, lowercase) , but to no avail.
Looking at the debug internals window, I see that the expression is
only (correctly) evaluated by gdb when I move the mouse over the
identifier
in the sources:
(gdb) <ptype AUNIT>
gdb doesn't know pascal strings, or how do an "=" operation on them.
You can try to get $_streq(myvar, "hello") to work....

Or use FpDebug. FpDebug can compare strings.
