## Caldera OpenLinux* 3.1

### Installing Intel ANS

In Caldera Open Linux* 3.1, the super-user’s executable path does not include /usr/sbin/, which is the default location selected by the makefile for Intel ANS installation. This causes problems later during the configuration stage. To solve this, either permanently add /usr/sbin to root’s executable path, or modify the makefile to set BIN_DIR to a preferred directory that is super-user specific and that appears in $PATH.

### Compiling Intel Drivers on Itanium™ -Based Systems

When compiling the e100 and e1000 drivers, various unresolved symbol errors may appear. These messages may be disregarded as the drivers will install and function properly on Caldera OpenLinux 3.1 Itanium™ -based systems.

## Red Hat* 7.0

### Compiling Intel Drivers:

To install Intel's e100, e1000, and iANS drivers on systems running Red Hat* Linux 7.0, you MUST have the kernel source package and kgcc. Without kgcc, the modules compiled for the stock kernel are compiled with gcc and may be unstable.

You can check for the required packages by typing:

> rpm -q kernel-source
> rpm -q kgcc

If you are missing a package, install it with the following commands:

> mount /dev/cdrom /mnt/cdrom (or copy from the web)
> cd /mnt/cdrom/RedHat/RPMS/ (or directory copied from the web)
> rpm -i kernel-source-2.2.16-22.i386.rpm
> rpm -i kgcc-1.1.2-40.i386.rpm

Then, you MUST reboot. This ensures that version.h is updated. You may then install the Intel driver(s) as indicated in the driver's readme file.

### Compiling Intel ANS on the 2.2.16 Kernel and Higher

In single-processor systems, the default kernel source tree configuration does not match the kernel. This causes errors when compiling the ANS module and might lead to a faulty module.

As a workaround, make the kernel configuration match the running kernel:

1. Change to the kernel source directory. Generally, this is /usr/src/linux.

2. Enter:

   > make mrproper

3. Enter:

   > make menuconfig

   | CAUTION: When entering the above command, you need to be sure to turn the versioning on or off as required by the kernel you are planning to run. If you are running a UP kernel, set SMP and versioning to off. If you are running a SMP kernel, set SMP and versioning to on.

4. Deselect SMP, save, and exit.

5. Enter:

   > make dep

6. If error messages still appear after performing the above operations, enter:

   > make bzImage
   > make modules

## Red Hat 7.0 Enterprise* Edition

### Matching the Kernel Source:

The Enterprise* kernel version (7.0) was built using extra patches and does not match the kernel-RPM installed source. You must install and apply the patches from the kernel SRPM to recreate the proper source tree.

| NOTE: The Enterprise kernel was developed to allow the 2.2.16 kernel large memory access and other Enterprise features. If you require Enterprise capability, we strongly suggest using the 2.4.X series of kernels, which have native large memory support.

Use the following instructions to recreate the 2.2.16-22 Enterprise kernel source:

1. Install kernel-2.2.16-22.src.rpm and kernel-source-2.2.16-22.i386.rpm.

2. Make a copy of the source tree installed from kernel-source-2.2.16-22.i386.rpm.

3. Apply the following patches from the kernel SRPM to the new kernel source tree:

   > /usr/src/RedHat/SOURCES/linux-2.2.16-lfs.patch
   > /usr/src/RedHat/SOURCES/linux-2.2.16-lfs-bigmem.patch

   | NOTE: Unresolved failure message have been observed on some systems. These message may be ignored as the patches do install cleanly.

4. Clean out the kernel source tree and reconfigure for the Enterprise kernel:

   > make mrproper
   > cp configs/kernel-2.2.16-i686-enterprise.config .config
   > make oldconfig
   > make dep

5. Ensure /usr/src/linux is a symlink pointing to the new Enterprise kernel source.

6. Build the driver.

## Red Hat 7.2

### Driver Installation on Itanium-Based Systems with Red Hat 7.2 or Higher:

When compiling the e100 and e1000 drivers with 'make install', the binaries are not installed in the default locations listed in the base driver readmes. Instead, the binary is installed as:

For e100: /lib/modules/[KERNEL_VERSION]/kernel/drivers/addon/e100.o

For e1000: /lib/modules/[KERNEL_VERSION]/kernel/drivers/addon/e1000.o

## SuSE 7.1

### Compiling Intel ANS or PROCfg on the 2.4.0 Kernel:

When trying to compile Intel ANS on the 2.4.0 kernel on SuSE* 7.1 systems, a compilation failure occurs, and a message regarding a missing config.h file is displayed. This failure occurs because the kernel source trees supplied, Linux-2.4.0.SuSE and Linux-2.4.0-4GB, are both empty and do not contain the necessary config.h and version.h files. A possible solution is to install either a new kernel from http://www.kernel.org or a new kernel tree package supplied by SuSE.

When installing and compiling openssl, a prerequisite for PROCfg, a compilation failure occurs, and a message regarding a missing errno.h file is displayed. This is another instance of the missing kernel source tree described above for ANS. Use the solution above to restore the missing file.
