I've recently noticed that my tests are not running and tracked the issue down to an empty TestSuites.inc file. After stripping my test cmake file to

project(test_failing Fortran)

file(GLOB pf_files "*.pf")

add_pfunit_ctest (${PROJECT_NAME} TEST_SOURCES ${pf_files} LINK_LIBRARIES ${MPI_Fortran_LIBRARIES} )

I now have a test_faling.inc file produced automatically with the necessary add suite line. However, when trying to make the test I get the following error:

test_failing.inc(1): error #7977: The type of the function reference does not match the type of the function definition. [FAILING_SUITE] call suite%addTest(failing_suite())

I couldn't find anyone with a similar error, and have spent the better part of an afternoon looking at the generated files fruitlessly. Am I missing something obvious?

For completeness, here's my top level CMakeLists.txt (and the test file is absolutely minimal so I've not included it here):

Looks like it's the -warn all flag. Removing it solves the problem. I'll have a look at the intel website, but I'd definitely prefer being able to toggle warnings.

I have been out of town for several days. I will try to look at this issue more closely over the coming weekend. But I agree there is some fragility in the construction of the .inc files that could possibly be improved. I usually have the luxury of just deleting my build tree and starting from scratch if I suspect a problem along these lines. Arises infrequently in practice, but may depend on other coding habits.
