python 安装mssql扩展

  linux下连接SQL SERVER 可是一件非常痛苦的事情,python下有pymssql扩展库去连接,但是安装确实比较麻烦和痛苦

开始很自然的想到

easy_install pymssql

出现

很自然以为系统没有安装python-devel

yum install python-devel

显示已经安装

然后从pypi下载软件包安装

python setup.py build

running build

running build_ext

skipping '_mssql.c' Cython extension (up-to-date)

building '_mssql' extension

gcc -pthread -fno-strict-aliasing -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv -fPIC -I/root/pymssql-2.0.0b1-dev-20130403/freetds/nix_64/include -I/usr/include/python2.6 -c _mssql.c -o build/temp.linux-x86_64-2.6/_mssql.o -Wno-parentheses-equality -DMSDBLIB

还是gcc 不过上面说skipping '_mssql.c' Cython extension (up-to-date)

然后查看build/temp.linux-x86_64-2.6/目录空空

说明库没有编译上

google了一下发现是freetds的问题

官方地址: http://www.freetds.org/

下载安装

过程如下:

tar xvf freetds-stable.tgz

cd freetds-0.91/

./configure   --with-tdsver=8.0 --enable-msdblib

make && make install
