Generating Source from IDL

The core RAPID messages specifications and APIs are written in IDL, an interface definition language, and follow the CORBA IDL format.

To generate language-specific source code for RAPID, follow the instructions on this page. Currently Java and C++ are supported.

• Establish the required environment
• Perform the command

For a Single IDL File

These commands will translate an IDL file into a Generated Source File, replacing any file with the same name that already exists in that location.

For Java: rtiddsgen -d ../generated-src -replace -language java filename.idl

For C++: rtiddsgen -d ../generated_src -replace -namespace -language C++ filename.idl

For All IDL Files

Because of the number of IDL files, it is usually more convenient to generate the source code using a batch file that process all the IDL files at once.

For Windows: for %X in (*.idl) do rtiddsgen -d ../generated_src -replace -namespace -language C++ %X

For Mac OS X and Linux

#!/bin/tcsh

# Generate code from IDL files

setenv NDDSHOME /opt/rti/ndds.4.5d
setenv XALANHOME /Users/dmittman/Development/xalan-j_2_7_1
setenv NDDSJREHOME /Library/Java/Home

pushd src-idl
foreach file (`ls *.idl`)
  $NDDSHOME/scripts/rtiddsgen -d ../generated-src -language Java -package gov.nasa.rapid.idl.dds -replace $file
end
popd
