using MinGW in windows XP to compile

 the client is 11.2

wondering if I am wasting my time. Trying to compile cdemo82.c (a sample) with MinGW. I do have oci.h and as far as I can tell it is being correctly used.

However, I am unable to produce a even a object file..

The errors returned are:

C:\DOCUME~1\pete\LOCALS~1\Temp\ccqkTnS2.o:cdemo82.c:(.text+0x4a): undefined reference to `OCIObjectPin'
C:\DOCUME~1\pete\LOCALS~1\Temp\ccqkTnS2.o:cdemo82.c:(.text+0x75): undefined reference to `OCIStringPtr'
