Testing Issues under cygwin64

Hi, everyone

I asked you about building error in #273 because I thought that that error is related to fail in
Unit test and Regression test. https://openfast.readthedocs.io/en/master/source/testing/index.html

But, I understood that is not related to it through I got some advise in #273
Apropos, I'd like to take this opportunity to thank respondent in #273

That aside, I explain testing issues

1. Unit test
   I followed this link https://openfast.readthedocs.io/en/master/source/testing/unit_test.html

I found similar issues in #193
I checked the respective directories correct
I ran FAST v2.1.0

2. Regression test
   I followed this link https://openfast.readthedocs.io/en/master/source/testing/regression_test.html

Errors while running CTest

I think that 37th case error is related to unit test error. but, I haven't the faintest idea about other that cases.

Please, give me some advise.
thank you

I've had a similar problem, the only successful test that I got was the beamdyn_utest. Then, when I tried to run manually using the python script “manualRegressionTest.py”, I’ve realized that the numpy version that I had installed (python37_numpy) was not being found during the tests. So, I installed the python36_numpy version and the majority of my tests passed.

[rafmudaf]

@traft1966 add the -v flag to ctest to get verbose output and share the results. You can do this for a single case with this command

ctest -R <case_name> -V

[rafmudaf]

@traft1966 were you able to test this further?

[manmathan299]

I am newer to openfast ..I have followed the installation instrutions...and i got the following errors for Building OpenFAST on Windows with CMake and Cygwin 64-bit as well as in linux...Building OpenFAST with CMake on Linux and Mac






hw can i rectify this to install in windows using cygwin64

[rafmudaf]

Which version of gfortran are you using both both ubuntu and cygwin and which version of OpenFAST (i.e. commit hash or tag)?

[manmathan299]

I am using gcc-fortran 7.4.0-1 for both in linux as well as Windows with CMake and Cygwin 64-bit ..i used openfast-master from the github which i think OpenFastv1.0 ..i tried to install with OpenFast1.0 manual

[manmathan299]

I tried again its showing this error...

[manmathan299]

I tried for third time with lower versions of (cmake-doc–cmake-gui–cygwin-devel–gcc-core–gcc-fortran–gcc-g++–git–make–makedepend) in cygwin i got the following error messages during installations






and finally after complition of make command i got the following message

after this as in the User manual OpenFast 1.0 "Grab a cup of coffee as this takes a while on Cygwin. Once the compilation is completed, theOpenFASTexecutableis present inOpenFAST/build/glue-codes/fast/openfast.exe"..i checked the exe file of openfast..it was available on the targetted folder..when i try to open...it showed the following message

and also as mentioned in the Readme file of r_test..

r-test

This repository serves as a container for regression test data for system level and module level testing of OpenFAST. The repository contains:

• input files for test case execution
• baseline solutions for various machine and compiler combinations
• turbine specific inputs

The baseline solutions serve as "gold standards" for the regression test suite and are updated periodically as OpenFAST and its modules are improved.

modules-local/

This directory contains module level tests for the modules found in the source code at openfast/modules-local.

beamdyn/

These BeamDyn specific cases are configured to run with the BeamDyn driver program rather than with a glue code.

glue-codes/

This directory contains system level tests for the various "glue codes" or drivers found in the source at openfast/glue-codes.

openfast/

These are the system level test cases taken from the FAST V8 CertTests.
Each test case directory contains the OpenFAST input file, .fst, and all other case specific inputs. All turbine specific inputs are linked by relative paths to their corresponding turbine data directory. See the individual test case README's for more information regarding the particular turbine model and portion of the OpenFAST system that is being tested.

The included turbine directories are:

• 5MW_Baseline - NREL offshore 5-MW baseline wind turbine
• AOC - Atlantic Orient Company 15/50 wind turbine
• AWT27 - Advanced Wind Turbine program blade 27
• SWRT - Small Wind Research Turbine
• UAE_VI - Unsteady Aerodynamics Experiment research wind turbine
• WP_Baseline - WindPACT 1.5-MW baseline wind turbine

The CertTest cases were recently renamed from the old style TestNN to more descriptive names. In general, the turbine abbreviation begins the case name followed by a concise description of the physics involved.

Baselines

The regression test compares locally generated solutions to the baseline solutions generated on a series of machine and compiler combinations. Currently, the supported machine/compiler combinations for successful regression testing are:

• linux-intel
• macos-gnu
• windows-intel
  Currently, the regression test supports only double precision solutions, so all
  baseline solutions are generated with a double precision build.

macos-gnu

These results were generated on a MacBook Pro running on macOS Sierra 10.12.6. The OpenFAST binary was compiled with gfortran installed through Homebrew's gcc package at gcc version 7.2.0 (Homebrew GCC 7.2.0). The math libraries in this build are found in the Accelerate Framework installed with Xcode command line tools at version 2347.

linux-intel

These results were generated on NREL's Peregrine HPC cluster running on CentOS 7.
The OpenFAST binary was compiled with Intel's ifort compiler version 17.0.5 and MKL 17.0.5 on Peregrine's Haswell compute nodes.

windows-intel

These results were generated on a Dell Latitude E7440 running Windows 7 Enterprise SP 1. The OpenFAST binary was compiled with Intel's Visual Fortran 17 update 4.

Updating the baselines

The baseline directories can be updated with the included updateBaselineSolutions.py. This script copies locally generated OpenFAST solutions into the appropriate machine - compiler baseline solution directory.

Usage: python updateBaselineSolutions.py source_directory target_directory system_name compiler_id
Example: python updateBaselineSolutions.py local/solution/TestName target/solution/TestName [Darwin,Linux,Windows] [Intel,GNU]

NOTE - ServoDyn external controllers for 5MW_Baseline cases

The cases using the 5MW turbine require an external controller for ServoDyn. The source code for three external controllers are provided, but they must be compiled and installed.

On Linux and Mac, cmake projects exist to compile the controllers with make.
For Windows systems, cmake can generate a Visual Studio project to compile and install the controllers.

**For all system types, create build directories at

• r-test/glue-codes/openfast/5MW_Baseline/ServoData/DISCON/build
• r-test/glue-codes/openfast/5MW_Baseline/ServoData/DISCON_ITI/build
• r-test/glue-codes/openfast/5MW_Baseline/ServoData/DISCON_OC3/build

and run cmake .. in each one. For Windows, add your Visual Studio version and architecture in the following command:
cmake -G "Visual Studio 14 2015 Win64" ..

Ultimately, three .dll's should be compiled and placed in the 5MW_Baseline parallel to the test cases that will be executed. For example, if the regression test is executed automatically with ctest or manualRegressionTest.py, all case files will be copied to openfast/build. In this case, these three controller libraries must exist:

• openfast/build/reg_tests/glue-codes/openfast/5MW_Baseline/ServoData/DISCON.dll
• openfast/build/reg_tests/glue-codes/openfast/5MW_Baseline/ServoData/DISCON_ITIBarge.dll
• openfast/build/reg_tests/glue-codes/openfast/5MW_Baseline/ServoData/DISCON_OC3Hywind.dll**

...i didnt get the following files as mentioned in the readme file (hilighted)

[rafmudaf]

@manmathan299 Good work in trying to get through your compiling problem.

FYI for Windows, you can simply download precompiled binaries from the OpenFAST releases page.

In Ununtu
I don't have a hint as to what might cause the compiler crash there. Unfortunately, my best advice is to delete your build directory and try again being very methodical about what you're changing. Gfortran 7.4 should work fine and any version of CMake newer than 3 will be fine. The first thing to try changing is the CMake flag CMAKE_BUILD_TYPE. Among other things, this sets the optimization level for the compiler. The default is Release. I suggest following these steps:

# 1. Delete your build directory
rm -rf build

# 2. Reconfigure CMake in Release mode
mkdir build && cd build && cmake .. -DCMAKE_BUILD_TYPE=Release

# 3. Compile and verify that your still get the crash
make

# 4. Reconfigure CMake in Debug mode
cmake .. -DCMAKE_BUILD_TYPE=Debug

# 5. Compile and verify that your still get the crash
make

In Cygwin
Youre misunderstanding the libraries here. The r-test README is referring to DISCON controller libraries. These are dll's that function as an external controller for the turbine. However, Cygwin is letting you know that you don't have blas properly installed. BLAS is the linear algebra math library. First, install BLAS, then compile again with make install.

Also, including screenshots and output from your procedure is useful, but please keep it limited to your specific error along with any other relevant information. Doing so will improve readability for anyone in the future. Even better is to copy the relevant text from your terminal and paste it with the proper formatting into the GitHub Issue so that it can be searched later.

[manmathan299]

Ok rafael..thanks for your valuable reply.. i willtry .and here after i will limit to specific error....

[manmathan299]

hai rafmudaf... installation in ubuntu was successful without errors by proceeding the following steps...

1. Delete your build directory

rm -rf build

2. Reconfigure CMake in Release mode

mkdir build && cd build && cmake .. -DCMAKE_BUILD_TYPE=Release

3. Compile and verify that your still get the crash

make

4. Reconfigure CMake in Debug mode

cmake .. -DCMAKE_BUILD_TYPE=Debug

5. Compile and verify that your still get the crash

make

then how can i start regression tests..???
