在python docker imag上安装simstring（SWIG）

Question

我试图在Python码头上安装C++包simstringpython:最新版本或python:3.7版)你知道吗

我采取的步骤是，按照回购协议的指示/根据我收集到的信息：

docker run -it python:latest /bin/bash
autoconf -i
apt-get install swig
git clone https://github.com/chokkan/simstring.git
cd simstring
./configure
cd swig/python
./prepare.sh --swig
python setup build_ext

这里有两个错误：

/usr/bin/ld: cannot find -liconv
/usr/bin/ld: cannot find -lpython

不知何故，我需要通过他们的位置来建立\u ext或者我认为是这样，但我找不到要链接的文件，也找不到如何链接他们。有什么想法吗？（很遗憾，Simstring pure不是python包的选项。）

更新

在按照下面的excellend答案构建docker映像之后，我进入下一个路障，看起来iconv仍然没有找到。顺便说一句，在3.7python中，这甚至无法构建。但3.8没问题。你知道吗

During handling of the above exception, another exception occurred:

Answer 1

您可以使用此Dockerfile:

FROM python:latest
RUN wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.16.tar.gz \
    && tar -xvzf libiconv-1.16.tar.gz \
    && cd libiconv-1.16 \
    && ./configure  prefix=/usr/local/lib \
    && make \
    && make install \
    && cd /usr/local/lib \
    && ln -s lib/libiconv.so libiconv.so \
    && ln -s libpython3.8.so.1.0 libpython.so \
    && ln -s lib/libiconv.so.2 libiconv.so.2

RUN apt-get update && apt-get install -y swig vim
RUN git clone https://github.com/chokkan/simstring.git
RUN cd simstring \
    && autoreconf -i \
    && ./configure \
    && cd swig/python \
    && ./prepare.sh  swig \
    && python setup.py build_ext \
    && python setup.py install

上次结果：
