Package the created toolchain as a tarball under the bin/ directory as
|
||||
OpenWrt-Toolchain-$(BOARD)-for-$(ARCH)$(ARCH_SUFFIX)-gcc-$(GCCV)$(DIR_SUFFIX).
|
||||
For example, a toolchain for the MIPS architecture might be named
|
||||
OpenWrt-Toolchain-malta-for-mipsel_mips32-gcc-4.8-linaro_uClibc-0.9.33.2.tar.bz2.
