c++ - Issues compiling Qt project with Google Protocol Buffer -
i building network application qt , protocol buffer. have server, can compiled successfully, , qt client, cannot compiled protocol buffer.
the server built running make on following makefile

my issue running make model alone can compile protocol buffer implementation files. including them sources , compile them qmake generated makefile not work.
the error follow:
