Problems with gcov

Problems with gcov

[igor.prakljacic]

Hello,

i`m trying to use the gcov tool to measure the code coverage of my ada-
code, but it seems no to work.
I tried to measure the following code: (helloworld.adb)

with Ada.Text_IO;
use Ada.Text_IO;
procedure helloworld is
begin
   Put_Line("Hello World");
end helloworld;

The next steps are:

% gnatmake -fprofile-arcs -ftest-coverage helloworld.adb
gnatgcc -c -fprofile-arcs -ftest-coverage helloworld.adb
gnatbind -x helloworld.ali
gnatlink helloworld.ali

% ls
helloworld  helloworld.adb  helloworld.ali  helloworld.bb  
helloworld.bbg  helloworld.o

% ./helloworld
Hello World

% ls
helloworld  helloworld.adb  helloworld.ali  helloworld.bb  
helloworld.bbg  helloworld.o


There is no helloworld.gcno file.
What am i doing wrong.

Thanks

flux

Not sure. The same sequence of steps works for me on Centos.
What GCC/GNAT version are you using and what OS?

GNATs based on GCC 2 (eg, GNAT 3.15p) use the .bb and .bbg files, and
the output would be in .da files. GNAT GPL 2006 (on Mac OS X at any
rate) uses the .gcno and .gcda files.

Ah! On this machine I get

$ gnatmake -fprofile-arcs -ftest-coverage helloworld.adb -f
gcc -c -fprofile-arcs -ftest-coverage helloworld.adb
gnatbind -x helloworld.ali
gnatlink helloworld.ali -fprofile-arcs -ftest-coverage

so the gnatlink call is different ...
