Re: Cannot find ODBC driver

I installed using yum, as in yum install unixODBC. I did a search for some of those files. a 'find -name sql*.h' yielded a single result: ./usr/include/sqlite3.h and 'find -name libodbc.so' yielded: ./usr/lib/libodbc.so

Do you recommend I unyum it and and install from source? I would hope that if it is yumable then the yum install would suffice.

You need to install unixODBC development with yum in addition to what you've probably already installed which is unixODBC runtime.

I don't use yum myself but normally unixODBC is split into runtime and development packages - you need both.

Hi, I am hoping someone here recognizes this problem:
I have installed unixODBC for use as a driver manager for DBD::ODBC. However, when I run the command: 'cpan DBD::ODBC' I end up with the following error:
Hmm...I cannot find an ODBC driver manager that I recognize.
...And I know about these drivers:
Microsoft ODBC, adabas, easysoft, empress, esodbc, informix,

Running make test
Make had some problems, won't test
Running make install

Perhaps the problem is that the ODBCHOME env var is set wrong? I have tried the following:
export ODBCHOME=/usr/bin
export ODBCHOME=/etc
both yield the same results... Could someone make a recommedation? Thanks!!

First, make sure you've installed unixODBC fully i.e. if you installed from some sort of package (not from source) you installed development support or you won't have the necessary headers (e.g. sql.h, sqlext.h, sqltypes.h etc).

DBD::ODBC needs to know where to find:

o sql*.h header files
o libodbc.so, the ODBC driver manager.

It is expected they all reside under a single path e.g. /usr/local in which the headers are looked for in /usr/local/etc and the libraries in /usr/local/lib (in this case you'd set ODBCHOME to /usr/local). It may be your unixODBC is installed such that headers are in /etc and libraries in /lib (in which case ODBCHOME should be /). If you have unixODBC installed not under a single path (e.g. headers in /etc and libraries in /usr/lib) this will cause you a problem since DBD::ODBC does not expect this and there is no way to specify different locations. In this latter case you will have to hack the Makefile.PL or Makefile or reinstall unixODBC under a single path.
