hi Peshala,
This is very simple, say you have packages packagex and packagey
And have designed messages in either of them, or even both
Say you have a message X.msg in packagex and want to use in packagey
in the manifest.xml of packagex, you need to add the following line
<export>
<cpp cflags="-I{prefix}/msg/cpp/"/>
</export>
then in manifest.xml of packagey you need to add the following line
<depend package="packagex"/>
The you should be set. To use the message in the cpp code all you need to do
is now include the message headers as
#include <packagex/X.h>
and proceed to use it in the code. For python you will just need to use
'from packagex import *'
There are also a number of tutorials online which explain this.
Have fun
