Snapcraft Python2 使用 python-dev 构建 numpy

刚刚开始接触 snappy。我正在尝试将一个 python 项目移植到一个 snappy 应用程序。python 代码依赖于 numpy 1.5.1，而 numpy 1.5.1 依赖于已安装的 python-dev。

我的 snapcraft 零件部分如下所示：

parts:
    mypythonapp:
        plugin: python2
        source: https://github.com/me/mypythonapp.git
        source-type: git
        build-packages:
            - gcc
            - gfortran
            - libblas-dev
            - liblapack-dev
            - cython
            - python-dev
        python-packages:
            - numpy==1.5.1

当我snapcraft pull尝试构建 numpy 时，出现以下错误：

    x86_64-linux-gnu-gcc: build/src.linux-x86_64-2.7/numpy/core/src/npymath/ieee754.c

我可以找到Python.h位于./parts/mypythonapp/install/usr/include/python2.7/Python.h。当我查看所有包含的路径时，我注意到它usr/include/python2.7不在那里。

有没有办法让我包含类似于 autotools 插件 configflags 的路径？还是我遗漏了一些简单的东西？

编辑env：我通过修改位于的 python2 插件中的函数 取得了一些进展/usr/lib/python3/dist-packages/snapcraft/plugins/python2.py

原始函数如下所示：

  def env(self, root):
    # This is until we figure out how to get pip to download only
    # and then build in the build step or split out pulling
    # stage-packages in an internal private step.
    env = [
        'CPPFLAGS="-I{} $CPPFLAGS"'.format(os.path.join(
            root, 'usr', 'include')),
        'CFLAGS="-I{} $CFLAGS"'.format(os.path.join(
            root, 'usr', 'include')),
    ]

我将其修改如下：

def env(self, root):
    # This is until we figure out how to get pip to download only
    # and then build in the build step or split out pulling
    # stage-packages in an internal private step.
    env = [
        'CPPFLAGS="-I{} $CPPFLAGS"'.format(os.path.join(
            root, 'usr', 'include')),
        'CFLAGS="-I{} $CFLAGS"'.format(os.path.join(
            root, 'usr', 'include')),
        'CPPFLAGS="-I{} $CPPFLAGS"'.format(os.path.join(
            root, 'usr', 'include', 'python2.7')),
        'CFLAGS="-I{} $CFLAGS"'.format(os.path.join(
            root, 'usr', 'include' 'python2.7')),
    ]

现在它捡起了Python.h，但它找不到scalartypes.c

x86_64-linux-gnu-gcc: numpy/core/src/multiarray/multiarraymodule_onefile.c
    numpy/core/src/multiarray/multiarraymodule_onefile.c:10:25: fatal error: scalartypes.c: No such file or directory
    compilation terminated.
    numpy/core/src/multiarray/multiarraymodule_onefile.c:10:25: fatal error: scalartypes.c: No such file or directory
    compilation terminated.

答案1

你所做的事情似乎是错误的，这些会引起冲突：

  • plugin: python2期望setup.py
  • python-packages: - numpy==1.5.1包含numpypython 包作为依赖项，为什么你说构建它。
  • build-packages: - gcc - gfortran - libblas-dev - liblapack-dev - cython - python-dev添加了所有这些 C/CPP 工具和库，就像要编译的可能是一个make，，autotools..项目

问题缺少原始代码或可供查看和重现的链接。不过，我建议：

  • 通过检查源/文档来拆分Parts:并设置每个所需的。plugin
  • 使用以下方式对构建过程进行排序：after
  • 是否真的需要构建依赖特定版本或从存储库中预构建的包就足够了？请参阅stage-snaps& stage-packages。
