aarch64pokylinuxgcc:错误：：没有这样的文件或目录

Question

我正在尝试将mlpack包含到我的yocto构建中。如果不启用python绑定，我的配方烘焙成功。 但是在构建python绑定时，我得到了以下错误：

我的食谱里还需要加些什么吗？ 或者构建环境缺少什么？在

Answer 1

首先运行ldd aarch64 poky linux gcc，检查它链接的所有库是否都存在于您的机器中，如果没有，系统会告诉您“没有这样的文件或目录”。在

Answer 2

mlpack通过多个步骤构建Python绑定：

• 构建一个generate_pyx_<name>程序来生成要编译的Cython.pyx文件
• 运行generate_pyx_<name>程序并保存输出.pyx文件
• 使用Cython和setuptools从.pyx文件生成一个.cpp文件，然后编译它

这是一个迂回的过程，但我相信这里发生的是generate_pyx_<name>程序是为设备而不是主机编译的，因此无法运行以生成.pyx文件。不幸的是，没有一种特别容易的方法来解决这个问题，因为CMake将使用与编译库其余部分相同的选项编译generate_pyx_<name>目标（在您的例子中，该选项针对的是设备）。在

为了使这项工作有效，您需要修改src/mlpack/bindings/python/CMakeLists.txt，特别是这一行

add_executable(generate_pyx_${name}
    ${CMAKE_BINARY_DIR}/src/mlpack/bindings/python/generate_pyx_${name}.cpp
    ${CMAKE_SOURCE_DIR}/src/mlpack/bindings/python/print_pyx.hpp
    ${CMAKE_SOURCE_DIR}/src/mlpack/bindings/python/print_pyx.cpp)

以及相关线路。实际上，您需要确保像-march=armv8-a -mtune=cortex-a57.cortex-a53这样的cxflag不会用于特定的目标。在
