Post by Thomas Petazzoni Hello, Since the toolchain wrapper support for the internal toolchain has been merged, using pre-built Buildroot toolchains as external toolchains no longer work since the path logic in the wrapper doesn't cope with a toolchain installed in host/opt/ext-toolchain/. . As you know, Buildroot installs all its host stuff in $ (HOST_DIR)/usr, and not directly under $ (HOST_DIR). The simplest way to use it is to add output/host/bin/ to your PATH environment variable and then to use ARCH-linux-gcc, ARCH-linux-objdump, ARCH-linux-ld, etc. This doesn't have the disadvantages of the other two, but is more work to implement.
