Hi,
I am trying cmake in cygwin for code coverage analysis using gcov. My
source code is arranged as follows
CMakeLists.txt src tests
./src:
CMakeLists.txt lib main.cpp
./src/lib:
reverse
./src/lib/reverse:
CMakeLists.txt reverse.cpp reverse.h
./tests:
CMakeLists.txt test_rev.cpp test_runner.cpp
My main make file is also given below
#Root cmake file
cmake_minimum_required (VERSION 2.6)
PROJECT (Tutorial)
SET (DO_TEST false CACHE BOOL "Enable Testing?")
SET (DO_CODE_COVERAGE false CACHE BOOL "Enable Code coverage?")
if(DO_CODE_COVERAGE)
MESSAGE (STATUS "Code coverage is enabled")
SET(CMAKE_CXX_FLAGS="-g -O0 -Wall -W -Wshadow -Wunused-variable
-Wunused-parameter -Wunused-function -Wunused -Wno-system-headers
-Wno-deprecated -Woverloaded-virtual -Wwrite-strings -fprofile-arcs
-ftest-coverage")
SET(CMAKE_C_FLAGS="-g -O0 -Wall -W -fprofile-arcs -ftest-coverage")
SET(CMAKE_SHARED_LINKER_FLAGS="-fprofile-arcs -ftest-coverage")
SET(CMAKE_EXE_LINKER_FLAGS="-fprofile-arcs -ftest-coverage")
endif(DO_CODE_COVERAGE)
ADD_SUBDIRECTORY(src/lib/reverse)
ADD_SUBDIRECTORY(src)
#Testing related code
if(DO_TEST)
MESSAGE (STATUS "Testing is enabled")
ADD_SUBDIRECTORY(tests)
#ENABLE_TESTING()
include( CTest )
ADD_TEST(NAME Test WORKING_DIRECTORY ${CMAKE_BINARY_DIR}/src/Debug COMMAND
test_rev)
endif(DO_TEST)
And the major portion of the cmake file of test executable is also given
below.
#Cmake file of Tests
cmake_minimum_required (VERSION 2.6)
SET(TST_SRC test_rev.cpp test_runner.cpp)
FIND_PACKAGE(Boost REQUIRED COMPONENTS unit_test_framework)
INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS})
INCLUDE_DIRECTORIES(${CMAKE_CURRENT_SOURCE_DIR}../../src/lib/reverse)
ADD_DEFINITIONS(-DBOOST_TEST_DYN_LINK)
ADD_EXECUTABLE(test_rev ${TST_SRC})
TARGET_LINK_LIBRARIES(test_rev ${Boost_LIBRARIES})
TARGET_LINK_LIBRARIES(test_rev Reverse)
if(DO_CODE_COVERAGE)
MESSAGE("Yes code coverage in test")
TARGET_LINK_LIBRARIES(test_rev gcov)
endif(DO_CODE_COVERAGE)
When I run, I get the following error
$ make ExperimentalCoverage
Site: llvm
Build name: CYGWIN-c++.exe
Performing coverage
Cannot find any coverage files. Ignoring Coverage request.
Built target ExperimentalCoverage
Why is the coverage files are not created?
Thanks,
Lloyd
