[IGSTK-Developers] gcov with Cygwin

[Luis Ibanez]

Hi Patrick

Did you added the following compilation flags ?


CMAKE_CXX_FLAGS:STRING=-Wall -g -O0 -fprofile-arcs -ftest-coverage
CMAKE_C_FLAGS:STRING=-Wall -g -O0 -fprofile-arcs -ftest-coverage


gcov can only analyze code that has been compiled
with this options.
