Here is the information I can provide.
The command like with which I am compiling the program (I am using a
makefile) looks something like below.

All these and a lot more shared libraries then get linked into a library
package which then is used to build a tuxedo server.
When I boot up the tux server, run some uds and then shut down the tux
server, I get .da files for a lot of source code files.

But this does not happen for all the source code e.g. the directory for
which I showed you the command line g++ above, there are no .da file
generated. Very much similar Imakefiles are being used to compile the entire
project.
In any case, when I run gcov like below, the output is shown.

My problem is that
1. It did not generate the .da files for each source code file compiled with
fprofile-arcs and ftest-coverage option.
2. It says 0% of the code was executed for most of my source code files.
However, the tux server does output some results looking at which I know
that a particular line got executed even though gcov says it has not.
