pyodbc.Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib '/usr/local/lib/libmyodbc8a.so' : file not found (0) (SQLDriverConnect)")

[silverlightjashmin]

i am aable to connect the same db using the odbc driver with isql but i am unable to connect using pyodbc.

[v-makouz]

Which OS is this? If isql works and pyodbc doesn't suggests they maybe using different drivers, if driver manager can open one but not the other. Which driver did you specify in isql?

[silverlightjashmin]

i am using ubuntu 20.04 os and i had called same driver for both isql and pyodbc.

my odbcinst.ini files has

[MySQL ODBC 8.3 ANSI Driver] DRIVER=/usr/local/lib/libmyodbc8a.so UsageCount=1

and odbc.ini has

[test] Driver=mysql SERVER=10.10.13.7 USER=root PASSWORD=Super@dm1n DATABASE=backoffice PORT=3306 now when i use isql test, db connection is successful and when i am calling same driver from pyodbc, it gives me pyodbc.Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib '/usr/local/lib/libmyodbc8a.so' : file not found (0) (SQLDriverConnect)") error.

I don't know if that is helpful, but I had pretty much the same issue and somehow got it working now. Though, first isql wasn't working, too. But after I did install one additional library package and also did set LD_LIBRARY_PATH correctly for the driver, isql was working. Pyodbc still not.

I then checked the installed version of pyodbc, which was 5.1.0 (installed yesterday via pip) and tried to downgrade it to 4.0.93. Then it suddenly worked. But strangely, after upgrading pyodbc again, first to 5.0.1 and then to 5.1.0, it still works. This confuses me… I don't think I have done anything other than using "pip install" between the last unsuccessful and the later successful tests...

What was the one additional library package that you installed? isql isn't working for me too.

I'm not sure anymore, but I think in my case it was one of those: libaio1, libodbc2, libodbcinst2 But that could depend on which ODBC driver you want to use.

Best is to check with ldd /path/to/odbc/driver.so if anything is listed as "not found".
