errors:
1."cannot find -lqsqlodbc"
2.collect2:ld returned 1 exit status

Did you build the static odbc driver plugin when building Qt?

[mammaiap]

Hi Wysota,
Thanks for your reply..

yes.. i build the odbc driver plugin statically when building Qt... after the static building it generates the "libqsqlodbc.a" file with 146KB in the "C:\Qt-4.7.0-Static\2010.05\qt\plugins\sqldrivers" directory...

is it OK? or is there any other files need to be generate along with "libqsqlodbc.a" file?

after that i slightly modified the *.pro and main.cpp ... please see the attachments...

now i got only one error : "collect2:ld returned 1 exit status"

and attached see the below compiler output ........

please help me to fix this problem..

Thanks,

Do you have ODBC libraries installed on your system? The plugin requires them.

[mammaiap]

Hi Wysota,

i have installed the "Microsoft SQL Server 2005" on my system... and i have done the system DSN for SQL server....

i dont know what you mean by "ODBC libraries installed"?.....

and one more thing there is no problem with dynamic linking ..... i can able to generate the *.exe and exe is working fine as per the expectation...

the only problem i am facing with "static linking"...

Thanks,

The missing symbols (such as this one: http://msdn.microsoft.com/en-us/libr...=vs.85%29.aspx) are from ODBC libraries the plugin needs to link against. It seems you are missing some development files for ODBC, maybe a static odbc library is required.
