有没有办法为qmake中的不同目标指定单独的编译选项?
例如:
QMAKE_CXXFLAGS += -O
SOURCES += file1.cpp
QMAKE_CXXFLAGS += -std=gnu++0x -O
SOURCES += file2.cpp
因此file1.cpp将仅使用-O选项编译,文件file2.cpp使用-std = gnu ++ 0x -O选项编译。

您可以创建并使用单独的“额外编译器”,如下所示:
# Use the built-in compiler for file1.cpp
QMAKE_CXXFLAGS += -O
SOURCES += file1.cpp
# Create a new compiler for file2.cpp
gnupp0x.input = SOURCES_GNUPP0X
gnupp0x.output = ${QMAKE_FILE_BASE}.o
gnupp0x.commands = g++ -std=gnu++0x $$QMAKE_CXXFLAGS ${QMAKE_FILE_NAME} -o ${QMAKE_FILE_OUT}
QMAKE_EXTRA_COMPILERS += gnupp0x
# Use the new compiler for file2.cpp
SOURCES_GNUPP0X += file2.cpp
