README


* Configuration:

ln -s ./extra/Configs/Config. ./Config

Then edit ./Config for your setup. In particular, modify CROSS and
KERNEL_SOURCE as necessary. You may also want to modify
SHARED_LIB_LOADER_PATH, DEVEL_PREFIX, and SYSTEM_DEVEL_PREFIX depending
on where you want to install the development environment. By default,
the development environment is installed into /usr/-linux-uclibc/.


* Building:

make


* Installing the development environment:

(As root, if necessary,)

make install

This will install the header files, libraries, and the gcc
wrapper into the directories defined in Config.


* Installing the target runtime environment:

(As root, if necessary,)

make PREFIX= install_target

This installs only the files that are necessary to run binaries
compiled against uClibc. Hint: You probably do not want to install
the target runtime environment on your host machine.


* Using uClibc:

To compile programs with uClibc,

export PATH={uClibc DEVEL_PREFIX}/bin:$PATH

and then just ./configure and make as usual.

Note:

You may also want to look at extra/gcc-uclibc/gcc-uclibc.c for
additional information concerning what options and environment
variables the gcc wrapper handles.

Note2:

There is an unwholesomely huge amount of code out there that
depends on the presence of GNU libc header files. We have GNU
libc header files. So we have committed a horrible sin in
uClibc. We _lie_ and claim to be GNU libc in order to force
many applications to work as their developers intended. This
is IMHO, pardonable, since these defines are not really
intended to check for the presence of a particular library, but
rather are used to define an _interface_. Some programs (such
as GNU binutils) are especially chummy with glibc, and need
this behavior disabled by adding CFLAGS+=-D__FORCE_NOGLIBC
