Rust's expected/produced library naming

What rustc/your linker expects

Rust handles libraries that it links with in a somewhat "magical" way, in that if you want to link to libpixman-1.so.0 you would just write:

println!("cargo:rustc-link-lib=pixman-1");

RPATH vs RUNPATH

I'm doing some ELF parsing and I need to simulate ld.so's lookup routine (man ld.so). To do that, I need to grab RPATH as well as RUNPATH from binaries, so to test my tool I naturally need to make some binaries with each of those. Here's how you do it.

cat <<EOF > /tmp/a.c
int main(){}
EOF
