Hello!
I have a hopefully simple question regarding the #pragma
construct. Specifically, I'm using the #pragma construct
available under g++ to minimize duplication of symbols
and templates when an include file with class definitions
is included in multiple source files.
Unfortunately, if I use this feature in my C++ files,
then UPS does not appear able to obtain the class
definitions in any except the class implementation file.
I have included a small example below demonstrating this
behavior. It is a uuencoded, gzipped tar archive. There
is a Makefile, and simply typing "make" will create and
launch ups (assumed to be in one's path) on the problematic
version of the program.
Within ups, create a breakpoint anywhere in the code, then
start it. Click on variable "a" in main(). You will see
the following listing for it:
undefined struct myPragmaClass <a> <Zero size object>
By avoiding the use of the #pragma construct (which can be
done by using "make no_prob"), this problem does not occur.
So, my hopefully simple question is, is this a problem with
using #pragma and trying to debug under UPS, or am I just
using a bad coding style? If it is the former, is this
something that can be handled by a relatively simple fix
to UPS?
Thanks!
