Hello, I'm new here of openwrt.Also new for cross complier. Sorry for my english
I want to build an openwrt-arm-img runing on some vm environment (like virtual box or qemu).
Useing Eclipse for develop on openwrt by remote to vm environment.
#1 Make:
I had svn trunk from openwrt.org. used make menuconfig to set target system with ARM Ltd .Realview board (qemu).
Check the "build openwrt sdk" "toolchain".
When I type command "make toolchain/install". It show no error.
"make V=s" show some error that I can't work out.
When I “make menuconfig" set target system with Atheros AR7xxx/AR9xxx. "make V=s" never show error.
Error:
