25 - ctest_fmi2_import_default_experiment_test (Failed) #8

Open ghost opened 4 years ago

Hello, everyone!

I've compiled 2.2.3 version of the library on Windows 10 with the help of the latest version of MinGW and MSYS.

mkdir mybuild cd mybuild cmake-gui ..

The only option I changed in configuration was: FMILIB_FMI_PLATFORM I set to win64 instead of win32 source code dir: fmi-library-master binaries dir: fmi-library-master/mybuild

Then I did: make make install make test

During the test I got an error for the default experiment test: Start 25: ctest_fmi2_import_default_experiment_test 25/35 Test #25: ctest_fmi2_import_default_experiment_test ............***Failed 0.10 sec

<...>

The following tests FAILED: 25 - ctest_fmi2_import_default_experiment_test (Failed) Errors while running CTest make: *** [test] Error 8

The library itself was compiled well and is located in the install directory.

Should I worry about this test failure?

Best wishes, I.E.

Hi!

The test failure is not expected. For MinGW we're testing with GCC-TDM (GCC 5.1).

  1. There should be more info about the test failure in mybuild/Testing/Temporary/LastTest.log. Could you paste it here?
  2. Does 2.2.0 work as expected?
  3. Do all other tests pass?

Thank you for the swift reply, Filip!

First, I compiled with GNU GCC-9.2.0-2 from the standard MinGW packages. Now, I tried with GCC-TDM 9.2.0, and it worked.

  1. If you're still interested in the log, you can find it in the attachment LastTest.log

  2. I haven't tried it yet because the whole installation process is rather complex. I'm in the middle now.

  3. Yes, all the other tests passed well.

Best wishes, I.E.

Ah, no! It's not all, actually.

In the next step, I've tried to install PyFMI-2.5 set FMIL_HOME=D:\FMILibrary-2.2.3 pip install pyfmi

However, I got the following error: fatal error LNK1181: cannot open input file fmilib_shared.lib

I compared win32 binaries from https://jmodelica.org/FMILibrary/FMILibrary-2.0-win32.zip with mine, and it turns out that the files don't have proper names: cd D:\FMILibrary-2.2.3\lib dir libfmilib.a libfmilib_shared.dll libfmilib_shared.dll.a

So I renamed _libfmilibshared.dll to _fmilibshared.dll and _libfmilibshared.dll.a to _libfmilibshared.lib and the installation of PyFMI went smoothly.

At the end, python-3.8.3 doesn't want to load pyfmi module: >>> import pyfmi Traceback (most recent call last): File "<stdin>", line 1, in <module> File "D:\ProgramData\Anaconda3\lib\site-packages\pyfmi\__init__.py", line 24, in <module> from .fmi import FMUModel, load_fmu, FMUModelME1, FMUModelME2 ImportError: DLL load failed while importing fmi: The specified module could not be found.

No idea how to fix this.

Best wishes, I.E.
