For Red Hat Linux releases ES/AS 4.0 and later | Dialogic 6.2

For Red Hat Linux releases ES/AS 4.0 and later:

The kernel source itself is not required; instead, a development kit is required. This kit is in the package whose name is of the form kernel-devel-<version>, in the file kernel-devel-<version>.i686.rpmor kernel-smp-devel-<version>.i686.rpm. This kit is automatically installed if you tell the Linux installation program to install everything. In this case, KERNEL_SOURCE should point to the appropriate subdirectory of /usr/src/kernels which would normally be one of <version>-i686or <version>-smp-i686.

Linux Directory Structure

The directory structure created when you install the Bfv API is based on the Linux compiler version:

Directory 3.4 contains files for Enterprise Linux ES/AS 4.0 Directory 4.1 contains files for Enterprise Linux ES/AS 5.0

Refer to the Dialogic® Brooktrout® Fax Products SDK Installation and Configuration Guide for the details of each directory.
