I have knoppix 4.0.2 kernel 2.6.12.
After installation of VMWare Workstation 4.x.x it needs to run 'vmware-config.pl which says that there is no prebuilt vmmmon modules and that I have an unsupported version of gcc ( 3.x.x ). I say Continue and i cant compile vmmon modules. Any-Any-patch cant help me.
PLS Do You know what to do except changing Linux.

I think that VMware Workstation 4.x.x will not build on newer kernels... Time for an upgrade, probably.

You either need to install a newer version of gcc (the GNU C compiler - 4.2) or install a more recent system. Considering that upgrading only GCC may break other components of your system, I think it would be better to choose the latter.

Know I've Upgraded to vmware workstation 5.0.0 and have the same problem. I even don't know what to do. I've deleted the '/etc/vmware/not_configured' file and now I don't need to run vmware-config.pl. Butnow I cant run virtual machines.
PLS Do you know what to do?
OR Do you know other soft similiar to VMWare ?

You can always try Virtualbox.

Thanks.
I have two more questions if you may.
First one : in vm workstation: when I try to power on the machine there is a message 'Unable to change virtual machine
status : Failed to connect to peer process'. I don't know what
to do.
Second one is : where can I get VirtualBox. If its shareware
then where is it for free?

Sorry, I cannot answer your question about VMWare but I can answer your question about VirtualBox. It used to be owned by a German company (I think it was German) but it was bought by Sun not so long ago. You can find the links here:
http://www.virtualbox.org/wiki/Downloads
There is a free version with some limitations (like no USB support) and a commerical version that does not have such limitations. The free version should be good enough for most folks. It is already included in the repositories of quite a few distros.

Thanks. I will try with VirtualBox.

But even now I wonna know howto solve the problem :::
in vm workstation: when I try to power on the virtual machine and there is a popup message 'Unable to change virtual machine
status : Failed to connect to peer process'.

I don't know, is Knoppix 4 supported?

Sorry if this sounds a bit harsh, but upgrading VMware when it tells you explicitly you need to upgrade your compiler is not going to magically "fix" things. This isn't mcrsft where you just uninstall and reinstall things to get it working. And as long as you have no working vmmon and vmnet kernel modules then anything else, like not configuring VMware properly, trying to run VM guests anyway, is a waste of time. I don't know if or how KNOPPIX regularly releases updated packages like any GNU/Linux distribution would do, but if it does not, then I would suggest moving to another distribution's maintained and current version first.


* Note that you can fix the "no modules for your kernel" warning by having your current kernel source configured and compiled to the point where you can build modules, unpack the vmmon and vmnet source tarball from the installation, compile manually and place the kernel modules in the /usr/lib/vmware/modules/binary/`uname -r`/objects/ directory and create a properties file like the other dirs have. When you succesfully completed that process you will no longer get the error when running vmware-config.pl. Note that you must use the same compiler version as your currently running kernel was compiled with.

Thanks. But I tried to compile manually the vmmon & vmnet modules. But as though I am newbie to linux I do not know what to do when I need to recompile or reconfigure the kernel. If you may, answer my PLS.
