Environment Variables

When building the drivers, you might need to override some default locations and

values. These values are set through environment variables. See the following table.

There are several build options:

■ “Build Option 1: Stock Kernels” on page 362

■ “Build Option 2: Custom Kernels” on page 363

■ “Build Option 3: Kernel With Upgraded OFED Stack” on page 364

■ “Build Option 4: Combination of Customer Kernel and Upgraded OFED Stack”

on page 365

Build Option 1: Stock Kernels

Source RPMs are available by request from Oracle Customer Support. If you will be

building a source RPM, contact Oracle Customer Support, who will provide

instructions for obtaining the image and can provide assistance with using the

source. You will need to provide Oracle Customer Support with some basic

information For more information, see “Required Information for Contacting

Customer Support” on page 368.

Be aware of the following:

■ Tested environments: RHEL4, RHEL5

Variable Description

kversion This environment variable can be set to specify the kernel version you would like to

build the Oracle host drivers for. The default value for this is the kernel you are

currently running with (e.g. uname -r).

ksrc This environment variable can be set to point to the directory of where the kernel

development headers and symbol files are located. The default directory is based on

where the kernel headers are for your running kernel (e.g.

/lib/modules/${kversion}/build).

XSIGOFLAGS This environment variable can be set to specify additional flags to the compiler such

as additional include paths and build parameters. Typically used to specify the

additional include paths for OFED installations which are not part of the kernel

source tree (e.g. export XSIGOFLAGS=" -I/usr/src/ofa_kernel/include").

Note that XSIGOFLAGS is automatically set through one of the external scripts when

OFED is installed.
