Adabas SQL Gateway Embedded SQL precompiler requires access to the RCI run-time library (RCICLNT.dll). ACEPCC is a console based application and is therefore invoked from the command line. Outside of the directory where ACEPCC is installed (See: Chapter 1 - Installation Instructions: Precompiler) the ACEPCC executable must be on the system search path or the full path to the executable must be specified on the command line. ACEPCC does not require a development environment to function, however, a development environment for ANSI C or C++ must be available in order to compile and execute the Precompiler output.
