Enable GCOV Support In Android Source Code!!

[Prince]

Hi All,

I want to enable GCOV Support in Android Source Code for all native
Applications.
And wants to generate HTML Report using LCOV Commands.

Currently, EMMA Support is present in Android Source Code.
Kindly help in enabling the GCOV in android source Code or provide any
pointers on this.

What I have analyzed is that if we use arm-eabi tool provided in ndk,
we cannot generate HTML reports using LCOV due to incompatibility
in .gcno files generated using ndk tool.

LCOV will work fine when we compile source files using the following
command "gcc -g -fprofile-arcs -ftest-coverage *.c".

Require your inputs, as I have to generate HTML Report for Android
Native Applications.

Thanks for your support.

Regards,
Pranjal

Hi

.gcno file format changes with different versions of gcc. You need to
check if your LCOV support the version of your gcc.

thanks

We have successfully modified lcov to support android
toolchain-generated .gcno files and I can provide a patch. Which version
of gcc are you using?

Sincerely,
Nick

Hi Nick,

We are using gcc 4.4.3 in Android.

It will be helpful for us in case some patch can be shared by you
along with the steps of usage.

We are working on Android 2.3 Version.
