Generating Source Code Generating the source code requires using the IDL compiler that comes with the CORBA implementation we are using. Here is how its done using TAO's IDL compiler. This will generate the source code in the 'TAO_generated' sub-directory. tao_idl -Ge 0 -cs C.cc -ss S.cc -sT S_T.cc -o TAO_generated HelloWorld.idl and now, using MICO's IDL compiler (code generated in the 'MICO_generated' sub-directory): (cd MICO_generated/ && idl --poa --no-boa ../HelloWorld.idl)
