Adding uClibc support for a new platform

Sometimes you want to cross-compile to another architecture, for example an

embedded devices. For embedded devices the uClibc C library is popular.

In Nixpkgs there is support for uClibc for several architectures but not

everything is supported.

Adding support is not very difficult,

In the latter directory you will also need a configuration file for uClibc.
23
-
You can make these by unpacking the uClibc sources and run a "make menuconfig".
24

In the configuration a few things need to be adapted:

-
26
-
- kernel sources -> need to point at our own kernel headers

-
- install -> needs to point at $out
