Set the toolchain's ARM CPU and FPU architectures by utilizing' gcc's --with-cpu / --with-fpu configure options that: "Specify which cpu variant the compiler should generate code for by default. cpu will be used as the default value of the -mcpu= switch." This will resolve the following kernel compilation failures under gcc 8.x on ARM because the kernel wants to set (possibly conflicting) optimization flags. .../ccyVnmrs.s:204: Error: selected processor does not support `dmb ish' in ARM mode .../ccyVnmrs.s:215: Error: architectural extension `mp' is not allowed for the current base architecture .../ccyVnmrs.s:216: Error: selected processor does not support `pldw [r4]' in ARM mode Because this is a big change, the .config and toolchain need to be refreshed (as in removed and regenerated).

To build your own firmware you need a Linux, BSD or MacOSX system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system. You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers installed. 1. Run "./scripts/feeds update -a" to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default 2. Run "./scripts/feeds install -a" to install symlinks for all obtained packages into package/feeds/ 3. Run "make menuconfig" to select your preferred configuration for the toolchain, target system & firmware packages. 4. Run "make" to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the Linux kernel & all chosen applications for your target system. Sunshine!
