Comtrol quick start RocketPort 550 Linux driver recompilation, Compilation procedure

7. RocketPort 550 Linux driver (re)compilation

Before compiling the RocketPort 550 driver, you must install the Linux kernel source code. Consult Linux on-line documentation and/or web hosted Linux documentation for the procedure. With the RED HAT Linux 8.0 boxed set distribution, the Linux kernel source is provided in a format ready for installation using RPM.

Following successful installation of the kernel source code, the kernel source tree root will be found at

/usr/src/linux2.4.xx.yy

where xx = sub level and yy=extra version

For example for the source distributed with the Red Hat 8.0 boxed distribution the path would be:-

/usr/src/linux2.4.18-14

This will differ for other distributions and kernels and may even differ with localised RED HAT Linux 8.0 distributions.

By way of another example, for Red Hat 7.3 boxed distribution the path would be:-

/usr/src/linux2.4.18-3

Compilation procedure

For the purposes of this example, it is assumed that the compilation is on a system with kernel revision 2.4.18-14

1.Make the symbolic link [root@localhost root] # cd /usr/src

[root@localhost src] # ln –s linux-2.4.18-14 linux

2.Navigate to the RocketPort 550 installaton directory because this contains the Source, rckt550.c and the makefile (this document assumes that this is /tmp/inst_comtrol.

[root@localhost src] # cd /tmp/inst_comtrol

3.Perform the compilation.

[root@localhost inst_comtrol] # make clean [root@localhost inst_comtrol] # make

If the make is successful and error free then a new rckt550.o will be produced.

You can now use the ‘install’ script to install the driver, return to installation step 4.
