python - aarch64-poky-linux-gcc：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，我的食谱会成功烘焙。但是在构建 python 绑定时，我收到以下错误：

我的食谱中还需要包含其他内容吗？或者构建环境缺少什么？

任何指针都会有帮助。

Answer 1

mlpack 通过多个步骤构建 Python 绑定：

• 构建一个generate_pyx_<name>程序来生成将被编译的 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 .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情况是generate_pyx_<name>程序正在为设备而不是主机编译，因此无法运行以生成 .pyx 文件。不幸的是，不会有特别简单的方法来解决这个问题，因为 CMake 将使用generate_pyx_<name>与编译库的其余部分相同的选项来编译目标（在您的情况下以设备为目标）。

为了使这项工作，您需要修改src/mlpack/bindings/python/CMakeLists.txt，特别是行

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)

和相关线路。本质上，您需要确保 CXXFLAGS 之类的-march=armv8-a -mtune=cortex-a57.cortex-a53不会用于该特定目标。

Answer 2

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