I was reading Learn C the Hard Way when I stumbled upon and followed the instructions for installing Valgrind, the C debugger. However, when I ran ./configure to setup build configurations, I got checking for the kernel version... unsupported (3.0.0-17-generic) configure: error: Valgrind works on kernels 2.4, 2.6 I am running Ubuntu 11.10, on the kernel Linux 3.0.0-17-generic x86_64. The answer may be obvious but I'm not acquainted with Linux: How do I get Valgrind working on my computer? Thanks.
