MATTest example files doesn't work on last Openmodelica

[ElMastro]

Dear Sir/Madam,
I shall report that running MATTest file from this library I can't get the simulation to work. The console writes:

The models in the other libraries work fine, so please let me know if someone can confirm this.
Thank you in advance

Just tested it with OMEdit 1.22.0~dev-91-gc254033 (nightly) in Linux and that works perfectly fine. Maybe you could try it with an updated version of OpenModelica?

[ElMastro]

Thank you for your quick answer. I tried it on 1.21.0.dev.r356.g49374551d7-1 version (on linux), and had this confirmed from another person. I will update the package and see if this problem disappear

[ElMastro]

Mr dietmarw,
I am sorry but I managed to build Openmodelica version 1.22.0.dev.r105.g997b5e0116-1. I also tried the other packaged version for Archlinux and it has the same error.
I would like to suggest, as I am the person that manages the installation scripts, could it be that the library 'ExternData' requires (inside Openmodelica) some dependencies that were dropped by?

For example, it seems that all the functions that give out errors are contained inside the 'hd5' package. Is there any way to check if it depends from something like this, please?

[dietmarw]

I think you should not build OpenModelica yourself but rather check with the available installers for your distribution. I can not find ArchLinux there so this makes it really hard to debug.
The hd5 dependencies are provided as statically compiled libraries in ExternData itself (see https://github.com/modelica-3rdparty/ExternData/tree/master/ExternData/Resources/Library/linux64)

[ElMastro]

I definitively agree with you. But, (I am sorry for the misunderstanding), there is no package for Openmodelica. There are two packages on Arch User Repository, one is at version 1.20 and the other one (openmodelica-git) is maintained by me. As far as I know, there is no other one (clean) possibility to have an Openmodelica package. As I racall Openmodelica has been updated during this last February, so I am not really 100% everything works (usually when something is wrong users posts on AUR or contact me).

[dietmarw]

So I tested it again with 1.22.0~dev-110-gaeb4aca on Ubuntu Linux and it works fine. So my guess is that something is wrong with the way you compile OpenModelica. But that is then rather an OpenModelica issue than an issue of this library. The library developer (which I'm not) would have no way to fix this, since it does work (also confirmed by OpenModelica's library testing: https://libraries.openmodelica.org/branches/master/ExternData/ExternData.html) . So maybe you can try the OpenModelica discourse for some help from the devs there.
