我收到以下错误：
In file included from generated/tandembiginteger.cpp:2:
generated/tandembiginteger.h:26: error: redefinition of `const int tandem::TandemMessageType_TandemBigInteger'
generated/tandembiginteger.h:26: error: `const int tandem::TandemMessageType_TandemBigInteger' previously defined here
generated/tandembiginteger.h:26: confused by earlier errors, bailing out
您可以看到重新声明和“之前”声明的地点是相同的。这是一个什么样的错误？怎么解决？
