Subject: Re: Unresolved external references when trying to link DLL app
Hello,
With respect to the unresolved references, have you included the LE libraries
in your SYSLIB concatenation? More info can be found here:

In the snippet you posted, I see where you use a #pragma map to map __ceetest's
name. I do not see an equivalent statement for "openadata".
>From my understanding the sidedeck would be concatenated to IEWL SYSLIN
You are correct. The sidedeck that is created would be concatenated on the IEWL
SYSLIN for programs that wish use the DLL.
