Valgrind support in OpenBMC

Valgrind support in OpenBMC

Hi,

I was experimenting on an application on top of OpenBMC. But apparently
there seems to be a memory leak that I'm not able to narrow down.
I am trying to build the image with Valgrind to analyze the error. But
valgrind is not identified as a compatible host.

Error observed:

bash-4.1$ bitbake valgrind

Loading cache: 100%
|#######################################################################################|
Time: 0:00:00

Loaded 2753 entries from dependency cache.

Parsing recipes: 100%
|#####################################################################################|
Time: 0:00:01

Parsing of 2046 .bb files complete (2045 cached, 1 parsed). 2755 targets,
380 skipped, 6 masked, 0 errors.

ERROR: Nothing PROVIDES 'valgrind'

ERROR: valgrind was skipped: incompatible with host
arm-openbmc-linux-gnueabi (not in COMPATIBLE_HOST)

I tried to meddle with the COMPATIBLE_HOST variables in the bb file present
in:
import-layers/yocto-poky/meta/recipes-devtools/valgrind/valgrind_3.11.0.bb

But it seems to throw some errors with respect to certain assembly
instructions.

Any pointers would be helpful.

Thanks,
Guhan

What BMC processor are you targeting? If it's ASPEED AST2400/2500,
then it's an ARMv6 processor and like that recipe file says...

# valgrind supports armv7 and above
COMPATIBLE_HOST_armv4 = 'null'
COMPATIBLE_HOST_armv5 = 'null'
COMPATIBLE_HOST_armv6 = 'null'

cheers
