Command not found

Issue: After installation of a package, the respective command is not found, e.g.

root@LEDE:~# ./examplecommand
-ash: ./examplecommand: not found

Root cause: Binaries compiled with older OpenWrt or LEDE versions will cause that kind of error due to changed libc versions. OpenWrt 14.07 and 15.05 still used uclibc, while OpenWrt DD trunk and LEDE use musl libc.

Solution: In order to make your package work you need to cross compile it again with the current LEDE toolchain.
