sybase自带的sybpydb模块用ucs2,而ubuntu14.04默认安装的python是ucs4,直接import会出错
$ pythonPython 2.7.6 (default, Jun 22 2015, 17:58:13) [GCC 4.8.2] on linux2Type "help", "copyright", "credits" or "license" for more information.>>> import sybpydbTraceback (most recent call last): File "<stdin>", line 1, in <module>ImportError: /opt/sybase/OCS-16_0/python/python26_64r/lib/sybpydb.so: undefined symbol: PyUnicodeUCS2_Decode故需要自己下载源码、编译安装
一、安装python
wget https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz
./configure --prefix=/opt/local/python27 --enable-unicode=ucs2
mak&sudo make install
二、安装setuptools（为了顺利安装其它模块）
wget https://pypi.python.org/packages/source/s/setuptools/setuptools-20.2.2.tar.gz
/opt/local/python27/bin/python setup.py build
sudo /opt/local/python27/bin/python setup.py install
这样源码安装的模块都在/opt/local/python27/lib/python2.7/site-packages 目录下了
或先安装pip（先下载get-pip.py,然后安装pip）：Installing with get-pip.py
To install pip, securely download get-pip.py. [1]:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
Inspect get-pip.py for any malevolence. Then run the following:
sudo /opt/local/python27/bin/python get-pip.py
这样/opt/local/python27/bin下面就有了pip和easy_install
注意:easy_install也要用/opt/local/python27/bin/下的那个版本,如安装matlab模块
sudo /opt/local/python27/bin/easy_install matplotlib
~$ /opt/local/python27/bin/pythonPython 2.7.11 (default, Mar 12 2016, 23:13:42) [GCC 5.3.0 20151204] on linux2Type "help", "copyright", "credits" or "license" for more information.>>> import sys>>> sys.path['', '/opt/local/python27/lib/python2.7/site-packages/setuptools-20.2.2-py2.7.egg', '/opt/local/python27/lib/python2.7/site-packages/MySQL_python-1.2.5-py2.7-linux-x86_64.egg', '/opt/local/python27/lib/python2.7/site-packages/ibm_db-2.0.6-py2.7-linux-x86_64.egg', '/opt/local/python27/lib/python2.7/site-packages/pymssql-2.1.1-py2.7-linux-x86_64.egg', '/opt/local/python27/lib/python27.zip', '/opt/local/python27/lib/python2.7', '/opt/local/python27/lib/python2.7/plat-linux2', '/opt/local/python27/lib/python2.7/lib-tk', '/opt/local/python27/lib/python2.7/lib-old', '/opt/local/python27/lib/python2.7/lib-dynload', '/opt/local/python27/lib/python2.7/site-packages', '/opt/sybase/OCS-16_0/python/python26_64r/lib']>>>可以看到/opt/local/python27/lib/python2.7/site-packages已经在自己编译的那个python的搜索路径了。
三、sybpydb.so模块加入到python路径
在该目录下创建sybpydb.pth（名字随便取、后缀必须pth）内容如下：
/opt/sybase/OCS-16_0/python/python26_64r/lib四、测试
vi sybpytest1.py
#!/opt/local/python27/bin/pythonimport sybpydbconn = sybpydb.connect(user='mymotif', password='wxwpxh', servername='MYMOTIFVOSTRO145480')cur = conn.cursor()cur.execute('select * from STUDENT')rows = cur.fetchall()for row in rows: print "-" * 55 for col in range (len(row)): print "%s" % (row[col])cur.close()conn.close()$ chmod +x sybpytest1.py
$ ./sybpytest1.py
