Re: [Boost-users] can't debug into BOOST_FOREACH?

Searching on the topic of Macro expansion and gdb, I found this page: http://www.delorie.com/gnu/docs/gdb/gdb_70.html Might be of interest for you, but that doc is for gdb 7.0. Might also apply for 6.8... Regards, Ovanes On Mon, Mar 2, 2009 at 2:14 PM, Ovanes Markarian wrote:

Hi there,

I just noticed there seems to be no way of debugging into a BOOST_FOREACH loop... Is that true?

I use g++ 4.3 / gdb 6.8 here and neither would the debugger stop any any breakpoint inside such loops nor can I step into them from outside. Is this supposed to be like that?

puzzled...

AFAIK BOOST_FOREACH is a macro. Therefore it is expanded by pre-processor into the real code. Can you debug into macros with g++/gdb anyway? MSVC supports that, but what about g++/gdb?

There might be some workarounds, like temorary modifying the BOOST_FOREACH code and placing a debug break compiler intrinsic call into it. I think than you might be able to stop the debugger inside, but not sure what is shown than.

Good Luck, Ovanes
