ESMF Version

v8.6.0

Issue

Hello, I am trying to build ESMF 8.6.0 in order to be used by TIE-GCM v3.0. I have tried in different Ubuntu versions and although "make build" finishes succesfully, "make all_tests" keeps failing a single test, namely ESMF_TimeUTest. However, "make install" finishes successfully. Is this test really important? Can I change something in my system to succed this test?
Many thanks,
Dimitris

During "make all_tests" the failure message is:
The following unit test files had failed unit tests:
FAIL: mpiuni/O: src/Infrastructure/TimeMgr/tests/ESMF_TimeUTest.F90
The following individual unit tests fail:
FAIL: mpiuni/O: Get Time Test 1, ESMF_TimeUTest.F90, line 138: Did not return 2004-01-29T12:17:58 or ESMF_SUCCESS
.......
UNIT TESTS SUMMARY
Found 7530 non-exhaustive single processor unit tests, 7529 passed and 1 failed.

That's puzzling. This is a fairly basic test of the ESMF time class, so it's surprising that this test would fail when all others pass.

Is it feasible for you to use the latest ESMF release (8.8.1) instead of 8.6.0? If so, I'd be interested to know whether this test still fails with the latest version.

If that isn't feasible, then can you please add the following print statement in src/Infrastructure/TimeMgr/tests/ESMF_TimeUTest.F90, at (I think) line 135 - between the line with call ESMF_TimeGet and the line with call ESMF_Test, a few lines after write(name, *) "Get Time Test 1":

      print *, "YY = ", YY, ", MM = ", MM, ", DD = ", DD, &
               "H  = ", H,  ", M  = ", M,  ", S  =", S, &
               "timeString = <", trim(timeString), ">"

(I think this code should work in 8.6.0. If you do this in the latest ESMF code base, change timeString to timeString19.)

Then please send me the resulting ESMF_TimeUTest.stdout file, which should be found in the directory pointed to by the statement at the end of the unit test run, "The log and stdout files for the unit tests can be found at:".

[baldimitris]

Thank you Bill.
Version 8.8.1 passes all the tests.
For 8.6.0 the ESMF_TimeUTest.stdout contains the following:
Beginning Test, file ESMF_TimeUTest.F90, line 96
NUMBER_OF_PROCESSORS 1
PASS Set Time Initialization Test, ESMF_TimeUTest.F90, line 126
YY = 2004 , MM = 1 , DD = 29 H = 12 , M = 17 , S = 58 timeString = <58>
FAIL Get Time Test 1, ESMF_TimeUTest.F90, line 139: Did not return 2004-01-29T12:17:58 or ESMF_SUCCESS
Ending Test, file ESMF_TimeUTest.F90, line 1155
PET 0 Test Elapsed Time 6.6000000000000086E-002 msec.

[billsacks]

Thank you for this follow-up and doing the additional testing. I believe what you're seeing is an issue that we fixed in 8.8.0, in #298. That issue just affects the string representation of time, so if your application doesn't need that string representation, then you can probably safely ignore this. If you think this might be a problem in your application, you can either use 8.8.1 or port the changes from #298 into the 8.6.0 source code before building.
