Re: [Valgrind-users] Valgrind on ARM embedded system

[Giuseppe A. <giu...@sa...>]

Hello,

I've installed Valgrind and I've added debug info to my libc.

But now, each time I try to launch Valgrind I have the following error:

/*root@mx27:/usr/local/lib/valgrind# valgrind ls -la*//*
*//*==1486== Memcheck, a memory error detector*//*

...any idea?
Thanks
