The Question is:
Attempting to debug a c program.
When I step/into a particular function the debugger returns with the message
'source code not available.'
this function is part of the program and not
an object that is link edited.
I am not the only programmer getting this
result.
Can you tell me why I am getting this message.
The Answer is :
You are receiving this error because the particular program unit
was not built with debug, or the the source code is not available,
or the source code was moved, or you have stepped into another
(shareable) image and need to enable scope, or you are working
with a language (such as embedded SQL) that requires you to
maintain the original source module and (when debugging) an
"intermediate" source module that results from the preprocessing,
or you are missing logical names or other access to the source
files. (Without more specific details, no more specific answer
is possible. That said, please review the SET SOURCE, SET MODULE,
and SET IMAGE commands available within the debugger HELP.)
The OpenVMS Wizard recommends a simple environment as a test, first
compile a simple example source module with the typical qualifiers
/DEBUG/NOOPTIMIZE, then link an executable image with LINK/DEBUG,
then try debugging the result. If you are working with a shareable
image and wish to test the debugging, then use the C code example
from Ask The Wizard topic (2486).
