Necroposting, baby
Did anybody noted that Amazon's source code archive for KT 5.3.7 (
Kindle_src_5.3.7_2004410010.tar.gz) contains
build_linaro-gcc_4.5.4.tar.gz with instructions about how to build GCC toolchain (basically, just run Makefile which will download and compile binutils and Linaro GCC)?
Build process is pretty straightforward. I've built it and described found building quirks at
Kindle_Touch_Hacking#GCC_cross-toolchain.
While in general the same toolchain (as was used for building KT's rootfs) isn't strictly required for building stuff, I believe C++ programs are sensitive to version of C++ standard library and its headers and there is no official way of building/getting this library/headers without building whole GCC also. So this toolchain will provide perfectly matched (to KT's environment) set of C++ headers, which could be helpful.
