OpenModelica

[capirossi1]

Hi all,

I read somethings about the OpenModelica troubles. My question, is the library working in openmodelica at all? Or is it just the examples that don't work?

kind regards

[overtaker]

Which OpenModelica version do you use on which platform and which operating system?

See also https://trac.openmodelica.org/OpenModelica/ticket/4448 for some more details.

I'm using the OMEdit v1.12.0 (64-bit) on Windows 10.
Can I conclude that it is not working at all? Then i will stop trying..

Luckily, there is an autotools build script provided by @sjoelund that should care for building the required MinGW binaries of ExternData libs.

Hi overtaker,
I tried to build autotools script (autogen.sh) in ExternData\Resources\BuildProjects\autotools\autogen.sh with minGW. However I stuck somewhere and got the error
"autoreconf-2.69: failed to run aclocal: No such file or directory"

Can you please guide how we can build those binaries?
Thanks in advance.

Should just be pacman -Sy automake1.16 in msys2.

Thank you @sjoelund for the prompt answer. I think I successfully ran autogen.sh with msys2. The screenshot of the files after I ran autogen is

However the OM error still exists as below. Maybe I missed something. Sorry for my innocence.
Thank you!

Hi,
I found the solution thanks to @vwaurich fork.
I added mingw32 and ming64 folders to my ExternData library. The files located in https://github.com/vwaurich/ExternData/tree/mingw/ExternData/Resources/Library

It works perfectly for me.
Thanks to everbody.

Hi,
is there a downloadable ExternData library that would work with out any errors /or require any modification to work with Open Modelica 1.17 and Modelica library 4.0.0
Thanks

The standard one should work rather well, provided that you use the Linux version of OpenModelica.

Dear sjoelund,
Thanks for prompt reply. I have only windows 10
what changes are requierd to make it run on Windows 10 ?
thanks

For OpeModelica 1.17+ on Windows you need these libs: https://github.com/adrpo/ExternData/tree/AddMinGWOpenModelicaLibs/ExternData/Resources/Library
Because the compiler cannot find the libs we try to build the library on the fly when we compile a model but fail to do so on Windows. You need to disable this until we find a solution for this bug: In OMEdit go to:
OMEdit->Tools->Options->Simulation->Additional Translation Flags: add: -d=-buildExternalLibs
if you have anything there just add it, i.e.:
-d=initialization,-buildExternalLibs
Then restart OMEdit and you should be able to run the example models.
