I ran ldd on the x86 build, and I get not a dynamic executable. So I
guess meaning there are no shared libraries of any sort. Okay.
Then I run <cross/>-ldd --root / <app/>, and it doesn't return
anything to me. But I doubt it would because I'm not linking any known
libraries to it dynamically.
Sorry it's been several years since dealing with C/C++, linkage
dependencies, etc, much less cross compilation issues.
Not sure about what libraries are there on the target. Probably I was
linking against a different version kernel? GLIBC? Or something like
I have updated my cross compiler to target kernel 3.7.1 instead of
3.7.3 (?) in the meantime.
