RE: Regarding environment variable GCOV_PREFIX

[Seenivasan, Hinduja]

Hi,

I have a problem in using GCOV_PREFIX environment variable. 

Compiler version that I am using on build machine - gcc version 3.4.6 20060404 (Red Hat 3.4.6-3)

I am compiling my source files (*.c) using "fprofile-arcs -ftest-coverage" on system ABC (build machine) 
which produces an executable, object files (corresponding to each source file) and gcno file 
(corresponding to each source file) in the following location

/tmp/test/gcovrun/result

This location is mounted on to another system XYZ (test machine). On XYZ, when I execute the 
executable, the same directory structure (/tmp/test/gcovrun/result) is expected for 
creating *.gcda files. 
But I do not want to create the same directory structure in my test machine. 

I want to create a directory (/tmp/gcovfiles) in my test machine and I want gcda files to be 
created in /tmp/gcovfiles location.

I tried using environment variables GCOV_PREFIX and GCOV_PREFIX_STRIP. But it did not have 
any effect. May be I am not using it properly.

Could you please help?

Thanks,
Hinduja

Regarding environment variable GCOV_PREFIX

Hi,

We are trying to use arm-linux-gcc 4.2.1.

We compile application with flags "-fprofile-arcs -ftest-coverage".

For the source file at location, /home/user/TestApp/HelloApp/,  .gcda
files are generated correctly in the folder
/home/user/TestApp/HelloApp/ on the target.

Setting environment flags GCOV_PREFIX and GCOV_PREFIX_STRIP do not
seem any effect in relocating the .gcda files.

For example, on setting GCOV_PREFIX=/temp/app/ and
GCOV_PREFIX_STRIP=4, there is no change at all.

How to fix this issue ?

Thanks And Regards,
