Hi I'm new face in ORB. I could not compile my small idl using omniidl. It says "Error Preprocessor running". What will be the problem in my idl compilation command. My Command is "E:\OmniORB Lib\bin\x86_win32\omniidl" -bcxx -Wbh=".h" -Wbs=".cpp" TestManager.idl. Any help is highly appreciated. Thanks Sahay.
