Download clean versions of the distribution and the three patch files for OpenRISC 1000 from the locations given in Section 2.3.

	Important
	Ensure the version number (0.9.28.3) is exactly the same.

Unpack the downloaded source code. Apply the main MOF patch to the main uClibc directory (See Section 3.1.1 for an example of how to apply a patch file.). Apply the supplementary MOF patch file to the libc sub-directory of the uClibc directory not the main directory.

A further patch is required to ensure uClibc will work correctly with the OpenRISC tool chain. The linker can get confused about the stdio library initialization and termination. To avoid this, dummy versions of __stdio_init and __stdio_term must be added. Apply the Embecosm patch file to the main directory to fix these problems.

The patches must be applied in this order. A typical set of commands would be:

cd uClibc-0.9.28.3
bzcat -dc ../uClibc-0.9.28-or32-unified.bz2 | patch -p1
cd libc
bzcat -dc ../../uClibc-0.9.28-or32-libc-support.bz2 | patch -p1
cd ..
bzcat -dc ../embecosm-esp2-or32-uclibc-0.9.28.3-patch-2.0.bz2 | patch -p1
