Re: DDD and STL

[Cal Erickson]

All,
Back in 12/30/02.. there was a message about looking at vectors compiled
with G++. Here is a paraphrase from that message:

"I had trouble looking at the contents of C++ STL vectors with DDD
inside my subroutines.  (Vectors inside main worked fine.)  When
printing the element (say) v[0],

(gdb) p v[0]

I got the error message

cannot subscript something of type `vector<double,allocator<double> >'

I dumped the error message into Google, and I found the answer at
address@hidden: compiling with the -ggdb flag in place of plain -g did
the trick.

g++ -ggdb -o foo foo.cpp

Voila.  Now printing v[0] shows the value of the vector element just as
if it were a C array."

I am far from a C++ expert but I thought I would offer this up as a
possible answer.
