Cross compile nzbget EM7075

From Eminent Opensource

Jump to: navigation, search

This page will show you how to cross-compile your own version of NZBGET for the EM7075. Note, NZBGET is already contained inside your unit, and this is only intended as an example to show how you can crosscompile a version that you changed or improved. Ensure the cross-compilation tools are installed and working, as explained [here.]

    • Nzbget requires several libs and headers that we need to build first.

And we're done! Your new nzbget-binary is now in /usr/mips/local/bin and ready to be integrated into the firmware. You can check if the output file is indeed correct: 

file /usr/local/mips/bin/nzbget
nzbget: ELF 32-bit LSB executable, MIPS, MIPS32 rel2 version 1 (SYSV), for GNU/Linux 2.6.12, dynamically linked (uses shared libs),
stripped

Please note, newer versions of NZBGet will eventually be picked up into the mainstream firmware releases, so there should be no need to cross-compile a version of your own (Unless you're living on the edge and wish to use the unstable or CVS version off course.)
