Python Informix、pyodbc、Centos

我正试图通过Informix连接我的工作数据库以创建脚本，但我在连接中遇到了问题

错误是：

 Traceback (most recent call last):
  File "./Test1.py", line 11, in <module>
    con = pyodbc.connect(constr, autocommit=False)
pyodbc.Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib '/opt/IBM/informix/lib/cli/iclit09b.so' : file not found (0) (SQLDriverConnectW)")

和my/etc/odbcinst.ini

[cms]

如何修复此问题以便正确连接

我更新了路径，所以我用ldd检查了，但问题是我得到了文件，但仍然是相同的错误：

[informix@localhost scripts]$ ldd /opt/IBM/informix/lib/cli/iclis09b.so
        linux-gate.so.1 =>  (0xf7786000)
        libifgls.so => /opt/IBM/informix/lib/esql/libifgls.so (0xf75c1000)
        libifglx.so => /opt/IBM/informix/lib/esql/libifglx.so (0xf75bf000)
        libc.so.6 => /lib/libc.so.6 (0xf73f8000)
        libm.so.6 => /lib/libm.so.6 (0xf73b4000)
        libdl.so.2 => /lib/libdl.so.2 (0xf73af000)
        libcrypt.so.1 => /lib/libcrypt.so.1 (0xf737f000)
        libpthread.so.0 => /lib/libpthread.so.0 (0xf7364000)

        libfreebl3.so => /lib/libfreebl3.so (0xf7360000)

在安装Informix文件时，我实际上更改了

/etc/ld.so.conf

：

include ld.so.conf.d/*.conf
/home/informix/lib/cli
/home/informix/lib/esql
/home/informix/lib
export INFORMIXDIR=/home/informix
export PATH=$INFORMIXDIR/bin:$PATH
export LD_LIBRARY_PATH=$INFORMIXDIR/lib:$INFORMIXDIR/lib/cli:$INFORMIXDIR/lib/esql:$LD_LIBRARY_PATH
export TERMCAP=$INFORMIXDIR/etc/termcap
export TERM=vt100
export DBDATE=DMY4/
export DBCENTURY=C
export DBEDIT=nano
export VISUAL=nano
export INFORMIXSERVER=cms_net
export ONCONFIG=onconfig.cms
export INFORMIXSQLHOSTS=/home/informix/etc/sqlhosts
export ODBCINI=/etc/odbc.ini

---

最后我可以解决这个问题，错误是我在Informix上有一个旧版本，所以我重新安装了另一个版本，这样我的驱动程序就可以工作了，所以也许这可以帮助别人

看起来您需要设置

LD\u LIBRARY\u PATH

或配置

/etc/LD.so.conf

，以便

/opt/IBM/informix/lib

和

/opt/IBM/informix/lib/esql

自动搜索共享库，这样也可以找到

libifgls.so

和

libifglx.so

。使用

ldd

是发现未找到内容的一种好方法。更改配置后，您可以使用

ldd

再次检查。您是如何设置

LD\u LIBRARY\u路径的，还是更改了
/etc/LD.so.conf
？“我不知道是否提供了任何见解。@乔纳森·利弗勒我添加了一份我的文件副本，我认为它是正确的
include ld.so.conf.d/*.conf
/home/informix/lib/cli
/home/informix/lib/esql
/home/informix/lib
export INFORMIXDIR=/home/informix
export PATH=$INFORMIXDIR/bin:$PATH
export LD_LIBRARY_PATH=$INFORMIXDIR/lib:$INFORMIXDIR/lib/cli:$INFORMIXDIR/lib/esql:$LD_LIBRARY_PATH
export TERMCAP=$INFORMIXDIR/etc/termcap
export TERM=vt100
export DBDATE=DMY4/
