Informix，pyodbc，Centos

Question

我正试图通过Informix连接我的work，以创建一个脚本，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)")

但是实际上我在机器上有这个文件，所以我使用了ldd并发现真正的错误是没有找到库libifgls.so和libifglx.so：

[jordaz@localhost scripts]$ ldd /opt/IBM/informix/lib/cli/iclit09b.so
        linux-gate.so.1 =>  (0xf777f000)
        libifgls.so => not found
        libifglx.so => not found
        libpthread.so.0 => /lib/libpthread.so.0 (0xf75db000)
        libc.so.6 => /lib/libc.so.6 (0xf741d000)
        libm.so.6 => /lib/libm.so.6 (0xf73d9000)
        libdl.so.2 => /lib/libdl.so.2 (0xf73d4000)
        libcrypt.so.1 => /lib/libcrypt.so.1 (0xf73a4000)
        /lib/ld-linux.so.2 (0xf7780000)
        libfreebl3.so => /lib/libfreebl3.so (0xf73a0000)

和我的/etc/odbcinst.ini

[cms]
Description           = MySQL connection to 'Kkapd' database
Driver                = MySQL
Database              = cms

和我的/etc/odbc.ini

[cms]

[Informix]

我怎样才能解决这个问题，这样我才能正确地连接？

我更新了路径，所以我用ldd进行了双重检查，但问题是我得到了文件，但仍然有相同的错误：

[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)
        /lib/ld-linux.so.2 (0xf7787000)
        libfreebl3.so => /lib/libfreebl3.so (0xf7360000)

实际上，我在安装Informix (文件)时更改了/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，所以我安装了另一个版本，这样我的驱动程序就可以工作了，所以这可能对某人有帮助！
