ESQL/C Compiling Error

I have written an ESQL/C program that consists solely of individual wrapper functions to be used by both C and Fortran programs. In other words, it doesn't have a <main> function. I used to be able to compile this bit of code on its own so that the object file could be compiled with whatever program required ESQL/C functionality, that is until some 'untraceable' changes occured to the system. I compile as follows: "esql -o epsql epsql.ec" ...And I get the following error: "Undefined first referenced symbol in file --------- -------------- main /lib/crt1.o ld: epsql: fatal error: Symbol referencing errors. No output written to epsql" If I put a <main> function in my epsql.ec program, it compiles standalone, but then I can't use the object to compile with any other programs. It gives me the following error: "ld: epsql.o: fatal error: symbol `main` multiply-defined, also in file test.o" Alternatively, if I use the esql compiler on the epsql.ec program along with a .c program (which contains a <main> function), then I'm ok. This is certainly a circuitous workaround and not one which our operations department is very fond of. Does anyone know why this mysterious "crt1.o" object file is requiring a <main> function? I can't get our operations department to untie the spaghetti of system changes that have occured since I last compiled successfully. Thank you for your help.
