you can install gcc inside your uml!

you mean, you want to use the host machinse gcc and libraries inside uml? (by hosfs mount or whatever?)
no - i wouldn`t recommend that.
you can compile your stuff outside your uml on the host itself and transfer the binaries to the uml afterwards - you just need to make sure that your host and your uml(root_fs) OS-version don`t differ too much - otherwise you will get problems with library dependency (that`s just the same issue as if you compile on a redhat 9 and transfer the binaries to a suse 6.4 :)

>If yes, how can I do it?
just as usual?
configurer
make
make install.....

  Hi,
      The root_fs, I am using for uml, does not contain gcc.
      
       Is it possible to compile a program using host machine's gcc and libraries?
       If yes, how can I do it?

  Thanks,
  Pronoy

  A little more data on this one - the behaviour I see with these mounts

mount -t hostfs none /mnt/mybob -o /view/myview/vob/myvob

pathname of the ClearCase vob.
    
This is a known bug in 2.4.24-2. A patch can be found in the archives or 
from http://marasystems.com/download/uml/

If you need hostfs then you should probably stick to 2.4.24-1 for the time
being. Jeff is doing some heavy restructuring of the uml host file access
methods while adding the humfs and as a result of this the hostfs support
has become very unstable while the combined supporting framework for humfs
and hostfs is taking shape. Hopefully this will soon result in a much 
better hostfs than before, but at the moment things is a bit shaky..
