I'm working with an embedded Linux deployment and am using a cross compiler tool chain that doesn't compile I2C library function calls.
How do I determine the precise versions of the libraries on the system so that I may rebuild the tool chain?
I don't intend to replace the libraries deployed, as I do know they work (including I2C), so I believe I need the following:
I think I can assume from the following that the binutils library is version 2.2.5. The kernel is modded for which I've the source.

For glibc:
/lib/libc.so.6
Sounds maybe strange to run a so file but should print out version information in this case
For the kernel version use uname
For the binutils parsing the output of ld --versionmight yield what you expect, the same for gcc --version. This is a bit tedious but I do not know another way.
