在ARM64 docker容器中编译typed-ast

Question

我在一个多体系结构的ubuntu仿生ARM64 docker容器中构建东西。 我正在使用conan进行依赖管理。 到目前为止，一切正常。

由于某些原因，我想从Python2.7柯南切换到Python3柯南。 而不是

ARG CONAN_VERSION=1.13.1
RUN apt-get update \
    && apt-get install -y --no-install-recommends \
    python-pip \
    && pip install wheel \
    && pip install "conan==$CONAN_VERSION" \
    && apt-get remove -y python-pip

我现在做

ARG CONAN_VERSION=1.13.1
RUN apt-get update \
    && apt-get install -y --no-install-recommends \
    python3-pip \
    && pip3 install setuptools wheel \
    && pip3 install "conan==$CONAN_VERSION" \
    && apt-get remove -y python3-pip

然而这打破了我：

#12 134.1     Running setup.py install for typed-ast: finished with status 'error'

显然编译认为它需要交叉编译器？ gcc已安装：

RUN apt-get update \
    && apt-get install -y --no-install-recommends \
    g++-5 gcc-5 make \
    python-dev python-setuptools \
    && rm -rf /var/lib/apt/lists/* \
    && update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 60 --slave /usr/bin/g++ g++ /usr/bin/g++-5

所以我真的不明白这里的问题是什么？

我试图强制使用'gcc'，但是没有用：

pip3 install --global-option build_ext --global-option --compiler=gcc "conan==$CONAN_VERSION"

#12 41.88     Complete output from command /usr/bin/python3 -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-vt3_j53z/typed-ast/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" build_ext --compiler=gcc install --record /tmp/pip-feshlu87-record/install-record.txt --single-version-externally-managed --compile:
#12 41.88     running build_ext
#12 41.88     error: don't know how to compile C/C++ code on platform 'posix' with 'gcc' compiler

我通过添加aarch64-linux-gnu-gcc的替代方案解决了我的问题

update-alternatives --install /usr/bin/$(gcc -dumpmachine)-gcc $(gcc -dumpmachine)-gcc /usr/bin/gcc 60 --slave /usr/bin/$(gcc -dumpmachine)-g++ $(gcc -dumpmachine)-g++ /usr/bin/g++
