【中文标题】RHEL 6.5 上的 pymssql - 使用 /opt/app/freetds 中的源代码安装 freetds

【英文标题】：pymssql on RHEL 6.5 - freetds installed using source in /opt/app/freetds

【问题描述】：

万事如意，

我正在尝试在 RHEL 6.5 上安装 pymssql。

我从他们的网站下载了 freetds 源并安装了它。

cd /opt/app
tar xfz /Prerequisites/freetds-stable.tgz
cd /opt/app/freetds-0.91
./configure --prefix=/opt/app/freetds
make
make install

在此之后，我尝试使用此命令安装 pymssql，但它失败了。

显然，它无法找到应该在 /opt/app/freetds/include 和 /opt/app/freetds/lib 文件夹中的必要头文件和库。

我能做些什么来解决这个问题？

请指导。

【参考方案1】：

感谢 runciter @ IRC #python 的提示。 . .我能够如下解决这个问题

export CFLAGS='-I/opt/app/freetds/include' 
export LDFLAGS='-L/opt/app/freetds/lib'
pip install /Prerequisites/pymssql-2.1.1.tar.gz --no-index --find-links /Prerequisites
