Compilation Error When Multiple Topics Share the Same Data Type

[tmori]

問題のコード

mros2/mros2_header_generator/templates_generator.py

Line 60 in 4d51853

datatext = template.render({ "includeFiles":includeFiles, "pubMsgTypes":pubMsgTypes, "subMsgTypes":subMsgTypes })

該当の変数は、pubMsgTypesとsubMsgTypesで、生成コードが同じ型のものが複数出て来ると思います。

修正方法

重複するものを削ればOK
