Question

我正在努力在OSX 10.8上编译PyGLPK。我已经安装了glpk和gmp 通过自制软件。我已经确认以下文件都存在的/ usr /本地/包括

gmp.h
gmpxx.h
glpk.h

但我仍然收到以下错误。

python setup.py build

有人可以就如何解决此问题提出建议吗？我试过玩路径和环境变量，但没有任何效果。

Answer 1

不确定这是一般修复，但它解决了我对GLPK的特殊需求。我刚刚恢复到旧版本并且有效。

首先卸载最新版本：

brew remove glpk

然后安装一个旧的（4.39）。

cd $(brew --prefix)
git checkout a82e823 Library/Formula/glpk.rb
brew install glpk

然后这很好用：

pip install glpk

Answer 2

本来会对原始问题发表评论，但我没有足够的声誉。

当我最近升级到带有GLPK 4.52的Ubuntu 14.04时遇到了同样的问题。许多旧的API已被弃用，不再可公开访问。我在这里有一个解决方法：https://github.com/bradfordboyle/pyglpk。

Answer 3

不幸的是，pyglpk不适用于较新版本的GLPK。我认为最后一个版本是GLPK 4.47。

Answer 4

我在Ubuntu 14.10 64bit上遇到了同样的错误。根据@daniel的建议，我安装了它：

下载并安装：http://ftp.gnu.org/gnu/glpk/glpk-4.47.tar.gz

$ ./configure
$ make install

下载并安装最新的pymprog：http://sourceforge.net/projects/pymprog/

$ python setup.py install

一切顺利。

EDIT1 ：请记住正确设置动态链接器路径

$ export LD_LIBRARY_PATH=/usr/local/lib

无法在OSX 10.8 / Ubuntu 14.x上编译pyglpk
