[Dev-C++] undefined reference to all ODBC API functions

[Waseem A. <was...@ya...>]

Dear Sir,
 
 I tried to comile a database program using ODBC API . During linking 'undefined reference to SQLAllocEnv'  error occurs. This error occurs for each ODBC API functions.
 
I am using sql.h, sqltypes.h and sqlext.h file with Dev-c++.
 
 
Please suggest solution to this problem.

The normal suggestion: Make sure that you are linking your application
with the required library. Header files are just an index of available
functions - just like the telephone catalog. They make the compiler happy.
Next step is to make the linker happy.

Hi Waseem,
 
I come across this kind of problem all the time in my own applications.  My solution to find the correct library to link is to use a text search application such as grep.  Then I execute
cd ~/dev-cpp/lib
grep -i -r  'SQLAllocEnv' * (FINDSTR in DOS/Windows I believe).
 
The results of this are pasted into the Project Options --> Parameters --> Linker window in the form:
-lSQL_Library
where SQL_Library is the correct library name, sans the extension.  As example I am working on a GIMP plug-in.  One of the required libraries is gimp-2.0.lib.  It's entry in the Project Options --> Parameters --> Linker window is:
-lgimp-2.0
 
Have a great weekend!
