Hi David,

The directory where the executable runs from (/scratch/trunk/tools),  
not the directory containing the test input.

I've confirmed with a getcwd() call at the top of the program.

Yes.

No, doesn't seem to be.

Don't think so, here's what CMake is writing to the CTestTestfile.cmake

ADD_TEST(bwr_melgen "/scratch/trunk/tools/melgen.x" "/scratch/ 
trunk_tests/_ShorterRuns/Plant Decks/BWR/_BWR_v2-0.inp")

SET_TESTS_PROPERTIES(bwr_melgen PROPERTIES  WORKING_DIRECTORY "/ 
scratch/trunk_tests/_ShorterRuns/Plant Decks/BWR")

-- Noel


Here's the expected output when I cd to the input test directory and  
run the executable.

[kbelco at wsblade001 BWR]$ /scratch/trunk/tools/melgen.x  _BWR_v2-0.inp
cwd = /scratch/trunk_tests/_ShorterRuns/Plant Decks/BWR



Here's what I get when I run ctest.

[kbelco at wsblade001 tools]$ ctest --verbose
