What does this warning mean, “overriding recipe for target”

[cq_qt]

There are some warnings that I don't understand:
overriding recipe for target 'debug/qrt_rc.cpp' Makefile.Debug 332
ignoring old recipe for target 'debug/qrt_rc.cpp' Makefile.Debug 334

How can I remove these warnings, thanks.

You have qrt_rc.cpp duplicated in your .pro file and the build system tries not to compile it twice.

[cq_qt]

@sierdzio .
I checked. There is no qrt_rc.cpp in my .pro file. And there is no qrt_rc.cpp file in my projects.
It is produced automatically by qt creator when I start to compile the projects. It is in the Build directory.
creator also produces Makefile.Debug file in the Build directory。 In this file，qrt_rc.cpp is invoked twice。
The compiler I use is migw810_32.

Do you define RC_FILE or RES_FILES anywhere in your .pro?

[cq_qt]

@sierdzio thank you. You help me solve the problem.
I don't define RC_FILE or RES_FILES in .pro file.
But I defined the RESOURCES by mistake：
RESOURSES +=
rc.qrc
rc.qrc
How stupid I am. Thank you again.
