如何為 python 3.6 安裝 lpsolve？

[英]How to install lpsolve for python 3.6?

 原文  2018-02-13 11:03:38  7   1    python/ c/ compiler-errors/ compilation

問題描述

所以我正在創建一個帶有 python 3.6 運行時的 Docker 容器。 我需要一個用於 python 的 lp_solver ( http://lpsolve.sourceforge.net/5.5/index.htm ) 的 UX64 版本。 鏈接的是python 2.7。 我發現了以下內容： https : //github.com/chandu-atina/lp_solve_python_3x但它也不起作用。 兩種方法都試過了。 我真的不知道如何讓這個 lp_solver 在 Ubuntu Python 3.6 上工作。 是否有類似以下內容： https : //www.lfd.uci.edu/~gohlke/pythonlibs/#lp_solve但對於 Ubuntu？

還發現了這個，它有效： https ://anaconda.org/snorfalorpagus/lpsolve 但我無法導入 lpsolve。 （這是導入 lpsolve 的鏈接問題： Conda 安裝 lpsolve ）

編輯 1：

以下是我采取的步驟：

mkdir -p /tmp/lp_solve && cd /tmp/lp_solve

wget -O ./lp_solve.tar.gz http://sourceforge.net/projects/lpsolve/files/lpsolve/5.5.2.0/lp_solve_5.5.2.0_source.tar.gz/download

tar -xf lp_solve.tar.gz

DOWNLOAD THE REPO FROM GITHUB  (https://github.com/chandu-atina/lp_solve_python_3x )

mkdir -p /tmp/lp_solve/lp_solve_5.5/extra/

//創建Python目錄！ 只要確保原點是額外的/Python

cp -R extra/Python_that_is_downloaded  /tmp/lp_solve/lp_solve_5.5/extra/ 

cd /tmp/lp_solve/lp_solve_5.5/lpsolve55

chmod a+x ccc

sh ccc

在sh ccc我在 .h 文件中遇到了大量的語法錯誤。 這里：

user@user-box:/tmp/lp_solve/lp_solve_5.5/lpsolve55$ sh ccc

對不起，當我附上代碼時，它給了我這里的錯誤。

我如何讓 lpsolve 在 raspbian 上使用 python 3.5.3：

從存儲庫安裝

apt-get install lp-solve # for shared object file (liblpsolve55.so)
apt-get install liblpsolve55-dev # for header files (e.g. lp_lib.h)

從 sourceforge ( https://sourceforge.net/projects/lpsolve/files/lpsolve/5.5.2.5/lp_solve_5.5.2.5_Python_source.tar.gz/download ) 獲取 Python 源代碼。

解壓tar文件

tar -xzf lp_solve_5.5.2.5_Python_source.tar.gz
cd lp_solve_5.5/extra/Python

通過運行開始安裝

bash build.sh

在我的例子中，源文件有一些與 python3 無關的問題。

  1. 找不到 lp_lib.h。 通過在 setup.py 的 include_dirs 中添加 '/usr/include/lpsolve' 解決
  2. hash.c 中定義的函數的多個定義錯誤。 通過從要在 setup.py 中編譯和鏈接的文件中刪除“hash.c”文件來解決。
  3. 未定義的引用符號。 通過向 setup.py 中的庫添加“colamd”解決

Python3相關問題：

  1. 打印 ... 已更改為打印（...）。 在 setup.py 中更新
  2. PyString 已更改為 PyUnicode/PyBytes，PyInt 已更改為 PyLong ( https://docs.python.org/3/howto/cporting.html )。 在 pythonmod.c 中更新
  3. Init 模塊功能已更改（ https://docs.python.org/2.3/whatsnew/node20.html ， PyMODINIT_FUNC 和 PyModule_Create與https://docs.python.org/3/c-api/module.html 之間的區別）。 在 pythonmod.c 中更新

驗證安裝是否按照 lpsolve ( http://lpsolve.sourceforge.net/5.5/Python.htm#Installation ) 文檔中的指示工作

>>> from lpsolve55 import *
>>> lpsolve()
