# Qmake makefile generation problem on Windows

• On Windows, using qt 5.4, I used qmake to generate makefiles for the QCacheGrind product. Qmake generated a makefile with the notation for a rule of:

{....\kcachegrind-0.7.4\cgview}.cpp{release}.obj::
\$(CXX) -c \$(CXXFLAGS) \$(INCPATH) -Forelease\ @<<
\$<
<<

But Gnu make on Windows does not understand the '<<' notation. What does it mean ? Am I supposed to be using some other 'make' utility to process the files that qmake generates ?

• Which specs are you using when calling qmake? Maybe you're using one that is not suitable for gnu make.
