libwebsockets libuv错误：‘M’可能在此函数中未初始化地使用

Question

我成功地交叉编译了libuv，并尝试交叉编译libwebsocket，但在make for arm with a buildroot工具链中得到以下错误。请给我建议。

libwebsockets
    cmake .. \
        -DCMAKE_TOOLCHAIN_FILE=~/buildroot/output/host/share/buildroot/toolchainfile.cmake \
        -DLWS_LIBUV_INCLUDE_DIRS=/tmp/cross/include \
        -DLWS_ZLIB_LIBRARIES=/tmp/cross/lib/libuv.so
    make
