installing minimserver on netgear R7000 router flashed with advanced tomato firmware

[dafart]

I do have ldd installed, however I'm not sure it works correctly, because ldd --version gives me "--version not found"

root@Tomato:/tmp/home/root# ldd -v /opt/java/jdk1.8.0_121/bin/java
-sh: -v: not found
root@Tomato:/tmp/home/root# ldd /opt/java/jdk1.8.0_121/bin/java
-sh: /opt/java/jdk1.8.0_121/bin/java: not found
