[omniORB] omniORB running in Cray XT4 without some glibc functions

Hi Dany,

Looking at where this function is called in unixTransportImpl.cc<http://omniorb.svn.sourceforge.net/viewvc/omniorb/tags/4_1_6/omniORB/src/lib/omniORB/orbcore/unix/unixTransportImpl.cc?revision=6064&view=markup>, I see that it is only actually used if:

1.       Your endpoint specifies to use a unix domain socket, without specifying a filename explicitly, ie:
endPoint = giop:unix:

2.       Your setting for unixTransportDirectory contains "%u" which needs to be expanded to the username (as documented here<http://omniorb.sourceforge.net/omni41/omniORB/omniORB004.html#toc23>).

It would appear to be easy to avoid the above circumstances where getpwuid is needed, in which case how about you just cut its use out of the above file for your own private build of omniORB?  Alternatively you could try providing your own stub implementation of getpwuid which does nothing.

I am using omniORB library version 4.1.6 in a HPC machine, a XT 4 machine (Franklin at NERSC).

The problem is that in the production nodes, a limited system call library is used. So, I don't have access to function like getpwuid() function.

Actually, I am getting this warning message:

omniORB/lib/libomniORB4.a(unixTransportImpl.o): In function `omni::unixTransportImpl::toEndpoint(char const*)':
unixTransportImpl.cc:(.text+0x408): warning: Using 'getpwuid' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

I know that I will not have that function available when I launch a program using the library.

Do you have any alternative, or there is a way to turn those function calls off?
