[omniORB] application attempted to invoke an operation on a nil reference

[Wittstruck, Nicholas]

I'm using the dir.mak from the echo example. Do I have to do any further changes? I tried to set up Visual Studio 2008 to run it, but I couldn't even start my application after compiling it. That is why I used the make file from the examples.

My make file looks like this:

----
#
# Usage:
#   nmake /f dir.mak [<build option>]
#
#  <build option>:
#      all       - build all executables
#      clean     - delete all executables and obj files
#      veryclean - clean plus delete all stub files generated by omniidl
#        
#
# Pre-requisite:
#
# Make sure that you have environment variable LIB and INCLUDE setup for
# using Developer studio from the command line. Usually, this is accomplished
# by source the vcvars32.bat file.
#

# Where is the top of this distribution. All executable, library and include
# directories are relative to this variable.
#
TOP = "..\omniORB-4.1.4"

# omniDynamic4_rt.lib is the runtime DLL to support the CORBA dynamic
# interfaces, such as Anys, typecodes, DSI and DII. In these examples, the
# runtime library is not required as none of these features are used.
# However, a bug in MSVC++ causes it to generate a bunch of references
# to functions in omniDynamic4_rt.lib when compiling the stubs.
# So now we link the dynamic library as well.
# An alternative is to replace the dynamic library with the much smaller 
# library msvcstub.lib. The smaller library contains nothing but stubs
# for the required functions. This is enough when none of the dynamic
# interfaces are used. We use the small library here. If you prefer
# to link with the dynamic library, swap the comment on the next 2
# lines.
