HARP matlab interface problem #235

Closed zebi90 closed 3 years ago

zebi90 commented 3 years ago

While using HARP in matlab interface, when i am loading data, they system error says, "Undefined function 'harp_matlab' for input arguments of type 'char'." Any kind of help will be appreciated.

svniemeijer commented 3 years ago

This means that the harp_matlab shared library cannot be found. Can you please explain what operating system you are using (and whether it is 32bit or 64bit), how and where you installed HARP, and how you configured MATLAB to update the search path?

zebi90 commented 3 years ago

Dear Sander Niemeiger Yes it seems like the harp_matlab library is missing. I am using Windows 10, 64-bit operating system and downloaded HARP from the following website: https://github.com/stcorp/harp/releases/tag/1.11. Regarding the MATLAB configuration to update search path, I have no idea at the moment, can you please help me in this regard?

Best wishes Muhammad Zohaib

Did you install HARP using the .msi file? Because that is the installer you should use.

It should provide you the harp_matlab library as a lib\harp\matlab\harp_matlab.mexw64 within your HARP installation directory (C:\Program Files\HARP by default). Does that file exist for you?

zebi90 commented 3 years ago

Dear Sander Niemeiger Yes I installed HARP using the .msi file from https://github.com/stcorp/harp/releases/tag/1.11 website, and the harp_matlab library is present in the designated location. Following error showed in command window. See the picture below: [image: image.png]

You can't attach images to github issues.

Did you follow the steps in the installation manual for MATLAB? Mind that you have to do exactly as it says there. Otherwise things won't work.

Also, you might have to logout/login again on Windows to make sure that your system wide PATH settings correctly includes C:\Program Files\HARP\bin.

Dear Sander Niemeiger I had followed the steps in installation manual for MATLAB. I am trying to read an ".nc" file, whereas the example is for ".asc" file. Could you please help me with this? The error in command windows shows as follows:

"Invalid MEX-file 'C:\Program Files\HARP\lib\harp\matlab\harp_matlab.mexw64': The specified procedure could not be found.

Error in harp_import (line 37) [varargout{1:max(1,nargout)}] = harp_matlab('IMPORT',varargin{:});

Error in Untitled (line 1) product1 = harp_import('C:\Users\HP\Downloads\S5P_NRTI_L2__AER_AI_20201003T072437_20201003T072937_15406_01_010302_20201003T075426.nc'); "

We are still building the windows binary installer using a very old version of MATLAB. I will see whether we can upgrade this to a more recent version for our next HARP release. Hopefully that will fix this.

zebi90 commented 3 years ago

Thank you for your coordination. I hope you will fix soon and let me me.

Best regards

We just released a new version of HARP. The windows binary installer is now build against MATLAB 2019b. Could you please check if this version solves the problem for you?

zebi90 commented 3 years ago

Dear Sander Niemeijer Thank you for your update. Unfortunately, the problem still persists for me, I don't know what I am missing. Please help me.

Best Regards

Did you install the vs 2015 package as is mentioned in http://stcorp.github.io/harp/doc/html/install.html#installing-the-binary-package-windows ?

If so, could you use the dependency walker as mentioned in https://www.mathworks.com/help/matlab/matlab_external/invalid-mex-file-error.html to find out if it mentions whether a certain file is missing?

svniemeijer commented 3 years ago

Do you have any update on this?

svniemeijer commented 3 years ago

Closing issue as there is no further update.
