LOG_DEL and LOG_NEW are macros for logging the dynamic allocation and
deallocation of memory to make debugging easier. I did not use ist and to be
honest I don't know how to do it. But I think it does not hurt to include it in
the code. You may want to look at: $PTOLEMY/src/kernel/logNew.h:
---------------------------------------------------------
Macros for use with the logging memory allocator. Use LOG_NEW
and LOG_DEL before calls to new and delete, respectively, in .cc
files. Use INC_LOG_NEW and INC_LOG_DEL in .h files.
If the symbol MEMORYLOG is not defined, these macros are dummies.
It is possible to do a "mixed" version of Ptolemy: some files compiled
with this symbol on, others not. If you do this, and logNew.cc was
built with logging on, then all allocation from files built with logging
off will be reported as being file "Unknown", line 0.
If MEMORYLOG is defined, all files must begin with a line of the form
static const char file_id[] = "this-file-name.cc";
before any include files are included.
