The Acu4GL for Informix product on UNIX is an add-on module that must be linked with the ACUCOBOL-GT runtime system. For this reason, you'll need a C compiler to install the Acu4GL product. To interface, you must use the ACUCOBOL-GT compiler and runtime, and the version of the runtime must match the version of Acu4GL.
The Acu4GL product is shipped as part of the main setup program detailed in the Installation Under UNIX section. The file required for the further installation steps in this section is placed in the lib subdirectory (of the installation directory).
Acu4GL is compatible with Informix versions 5.x1, 7.2, 7.3, 9 and later.
