[Xenomai-help] A second Xenomai on the same PC

[Andreas Vogt]

Hello,
I have install Xenomai 2.4.1 with Linux Kernel 2.6.22.16 and it works fine. Now i want install a second Xenomai on my PC to test a different Configuration. So, it is possible to install a second Kernel with the same Xenomai? Or are there any problems?
Thanks for all your help
Andreas

Yes, it may be possible if the ABI revision did not change between the
two versions (for instance if you want to install Xenomai 2.4.2
kernel-space support with Xenomai 2.4.1 user-space support). Otherwise,
you can install Xenomai with a different prefix (using the --prefix
option of Xenomai configure script), this will allow you to have two
versions of Xenomai user-space support installed.

For the kernel, you may use the option CONFIG_LOCALVERSION, so that the
kernel modules will get installed in another directory, and will not
override your first installation.

About kernel-space/user-space mismatches, Xenomai handles an ABI
revision number. So, if you try a bad user/kernel combination, you
should get an error message when starting your applications.

But you can install two versions of Xenomai user-space support as well,
if you use the --prefix option of xenomai configure script.
