Valgrind

Valgrind


Hello:

I need to use Valgrind to debug an application. However it seems not to be installed on Devcloud. Morover, it depends on libc6-dbg, so I cannot install it at my home from source either. How can I use this tool on Devcloud?

Thank you.

Hello, AthiraM.

I have done what you suggested. Unfortunatelly, Valgrind shows the same error message:

valgrind:  Fatal error at startup: a function redirection
valgrind:  which is mandatory for this platform-tool combination
valgrind:  cannot be set up.  Details of the redirection are:
valgrind:  
valgrind:  A must-be-redirected function

Thank you
