I am triying to use the mysql odbc driver.
The odbc. ini looks:

[MySQL5]
Driver = /usr/lib64/libmyodbc5.so
Description = Connector/ODBC 5.1 Driver DSN
SERVER = localhost
PORT =
USER = eld
Password =
Database = test
; OPTION = 3
SOCKET =

When I test the configuration with isql -v I get a big backtrace

*** Error in `isql’: free(): invalid pointer: 0x0000000000ea8068 ***

Is there some reason why you’d use an app (isql) that last received a code update in 2007?

Although it’s not an absolute indication the problem is with the app, in general I’d personally avoid un-maintained software unless there was on choice, and even then I’d have to feel pretty good about being able to dig into the code myself personally if needed.

There are numerous other apps in the OSS repo and elsewhere that would probably be more reliable… if you even wanted to avoid using the reliable standard CLI tools.

No, I am using the newest version OpenSuSE 13.2. The version of the unixODBC package is unixODBC-2.3.2-2.2.1.x86_64.

I think, I have a problem in the configuration but I cannot identify what I am doing wrong.

Where did you get your isql app from?

My previous post had nothing to do with openSUSE.
If you look at the isql code on sourceforge, you’d see that the code hasn’t changed since 2007.

Hi Emilio! i have the same problem, but using Opensuse 13.1: at some point i upgraded mysqlodbc and stop working.
Please let me now if you already resolved the problem:

i believe that if you make a fresh install with opensuse 13.1 without upgrading, the isql wont be broken.
