Dialogic 6.2 - Manual (Page 424)

November 2009 424
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-, in the file kernel-devel-.i686.rpm or
kernel-smp-devel-.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 -i686 or -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.
