以在高山码头容器上安装pyorc

Question

发现编译误差 - 取决于兽人二进制文件。

In file included from src/_pyorc/_pyorc.cpp:1:
src/_pyorc/Reader.h:7:10: fatal error: 'orc/OrcFile.hh' file not found
#include "orc/OrcFile.hh"
         ^~~~~~~~~~~~~~~~
1 error generated.
error: command 'clang' failed with exit status 1

如果我也单独编译

APACHE-ORC，我该如何将其引用到Pyorc Pip安装？ 任何人都有任何解决方案或想法，我们如何在高山容器中安装

Pyorc

软件包。 我在ubuntu和普通的python docker上遇到麻烦。 docker图像：FROM python:3.7-alpine

我使用的Docker多阶段构建：

# Dockerfile

FROM python:3.7.3
WORKDIR /app
RUN pip install pyorc -t .

FROM python:3.7.3-alpine
WORKDIR /app
RUN apk add --no-cache --virtual .build-deps g++ musl-dev gcompat
COPY --from=0 /app .

Answer 1

似乎有效：

$ docker build -t test .
$ docker run -it --rm test python
Python 3.7.3 (default, Jun 27 2019, 22:53:21)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyorc
>>>
>>> with open("./new_data.orc", "wb") as data:
...     with pyorc.Writer(data, "struct<col0:int,col1:string>") as writer:
...         writer.write((1, "ORC from Python"))
...
>>> from pathlib import Path
>>> Path("./new_data.orc").read_bytes()
b'ORC\x1d\x00\x00\n\x0c\n\x04\x00\x00\x.....'

Pyorc-docs

我将使用多阶段的Dockerfile来构建Pyorc，然后在其余的应用程序中将车轮安装到干净的高山图像中。 像这样的东西：

FROM python:3.8.3-alpine AS builder
RUN apk add gcc g++ musl-dev cmake make
ARG VERSION=0.3.0

RUN mkdir build
WORKDIR /build
RUN pip install pybind11 wheel
RUN pip download --no-binary :all: --no-deps pyorc==${VERSION} && tar -xvf *.tar.gz
RUN cd pyorc-${VERSION} && python3 setup.py build_orc
RUN cd pyorc-${VERSION} && python3 setup.py bdist_wheel

FROM python:3.8.3-alpine
ARG VERSION=0.3.0

COPY --from=builder /build/pyorc-${VERSION}/dist/pyorc-${VERSION}-*.whl /tmp/
# Adding libstdc++, because the wheel expects that the libstdc++.so is presented on the system.
# Adding tzdata, because the ORC C++ lib needs to have a localtime set.
RUN apk add libstdc++ tzdata
# Setting localtime to UTC.
RUN ln -fs /usr/share/zoneinfo/Etc/UTC /etc/localtime
RUN pip install /tmp/pyorc-${VERSION}-*.whl && rm -rf /tmp/pyorc-${VERSION}-*.whl
# Rest of your custom image...

我遇到相同的错误，我将其定义为BELEW：

Answer 3

compilepyorc

mkdir deps
cd deps
mv orc/build/_CPack_Packages/Darwin/TGZ/ORC-2.2.0-SNAPSHOT-Darwin/*  .
cd ..
pip3 install pybind11
export PYORC_SKIP_ORC_BUILD=1
python3 setup.py install

Btw，我使用GitHub

的最新版本和PYORC
