fastddsgen.bat .\HelloWorld.idl Error

[wanghuqiang123]

OS:windows11+vs2019
I install fastdds using binary packages on Windows,I use HellowWorldExample,
I tried to generate the idl file using fastddsgen myself, but when I ran fastddsgen.bat/Helloworld.idl, the following error occurred:

Processing the file .\HelloWorld.idl...
ERROR: Cannot execute the preprocessor. Reason: Cannot run program "cl.exe": CreateProcess error=2, The system cannot find the specified file,

I am a beginner and I would like to know if it is necessary to use the fastddsgen tool and idl file before using fastdds

Hi @wanghuqiang123 thanks for using Fast DDS.
I would recommend you use the Visual Studio Developer Command Prompt to avoid this issue.
You can also run fastddsgen with the flag -ppDisable to disable preprocessor, or with the flag -ppPath with the preprocessor path.
