# config NATIVE_TOOLCHAIN bool prompt "Use host's toolchain" if DEVEL && BROKEN default n help If enabled, OpenWrt will compile using your existing toolchain instead of compiling one menuconfig TOOLCHAINOPTS bool "Toolchain Options" if DEVEL depends !NATIVE_TOOLCHAIN menuconfig EXTRA_TARGET_ARCH bool prompt "Enable an extra toolchain target architecture" if TOOLCHAINOPTS default n help Some builds may require a 'biarch' toolchain. This option allows you to specify an additional target arch. Most people will answer N here. config EXTRA_TARGET_ARCH_NAME string prompt "Extra architecture name" if EXTRA_TARGET_ARCH help Specify the cpu name (eg powerpc64 or x86_64) of the additional target architecture. config EXTRA_TARGET_ARCH_OPTS string prompt "Extra architecture compiler options" if EXTRA_TARGET_ARCH help If you're specifying an addition target architecture, you'll probably need to also provide options to make the compiler use this alternate arch. For example, if you're building a compiler that can build both powerpc and powerpc64 binaries, you'll need to specify -m64 here. source "toolchain/binutils/Config.in" source "toolchain/gcc/Config.in" source "toolchain/uClibc/Config.in" config GDB bool prompt "Build gdb" if TOOLCHAINOPTS default n help Enable if you want to build the gdb config LARGEFILE bool prompt "Enable large file (files > 2 GB) support?" if TOOLCHAINOPTS default y help Enable large file (files > 2 GB) support config SHADOW_PASSWORDS bool prompt "Enable shadow password support?" if TOOLCHAINOPTS default y help Enable shadow password support. config SOFT_FLOAT bool prompt "Use software floating point by default" if TOOLCHAINOPTS default y depends on (arm || armeb || powerpc) && !HAS_FPU help If your target CPU does not have a Floating Point Unit (FPU) or a kernel FPU emulator, but you still wish to support floating point functions, then everything will need to be compiled with soft floating point support (-msoft-float).
