* Configuration: cp ./extra/Configs/Config.<target arch> ./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/<arch>-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=<temporary path> 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.
