Обсуждение: cannot find odbc library to link to for c program

   SUMMARY:

   I have written a c program that uses odbc functions, I do not know the
   name of odbc postgres library I need to link to on windows.

   Can someone tell me the name of the library and where I can find it.


   DETAILS:

   To compile the program on unix I just need to link to lodbc

   The final link command on unix (aix433 in this case) looks like this:

   % gcc -o function_tester -L/host/f/postgresql-8.1.3/aix433/lib
   ceargs.o function_tester.o  -lodbc -llcfdb -Wl

   On windows I get the following error that indicates to me that I need
   a comparable odbc library to link to on windows.

    % link /nologo /warn:3 /NODEFAULTLIB:libcpmt.lib
   /out:function_tester.exe
   *.obj *.res  lcfdb.lib   "/libpath:d:\host\f\postgresql-8.1.3\lib"
   "/libpath:D:\Progra~1\Micros~1\VC98\lib"

    setargv.obj commode.obj

   lcfdb.lib(oconnect.obj) : error LNK2001: unresolved external symbol
   _SQLDisconne[1]ct@4
   lcfdb.lib(oconnect.obj) : error LNK2001: unresolved external symbol
   _SQLFreeHand[2]le@8
   lcfdb.lib(oconnect.obj) : error LNK2001: unresolved external symbol
   _SQLAllocHan[3]dle@12
   ...

   function_tester.exe : fatal error LNK1120: 11 unresolved externals
   NMAKE : fatal error U1077: 'link' : return code '0x460'
   Stop.

 Other information:

   The installation I am using on windows (and unix) is postgres 8.1.3.
   I installed on windows using the postgresql-8.1.msi installer program.

   I use nmake and cl from Microsoft visual studio to compile.


Thanks

Doug

This isn't psqlodbc related question. You may search the answer in
Microsoft KB. When you write application using ODBC you work with
ODBC manager not directly with the driver (psqlODBC, MyODBC, ...).
