[AJamesPhillips]

Thank you so much for this library. I'm running:

• Windows 10
• OMEdit 1.14.1 (previously 1.18.0 but ran into the same bug as in Issues when compiling FMU from OpenModelica  #7)
• Binary installation instructions for Bodylight-VirtualMachine
• Plus went into the virtual machine and pulled the latest Bodylight.js-FMU-Compiler code as per your advice on Issues when compiling FMU from OpenModelica  #7

With the FMU from 1.18.0 uploaded to http://localhost:8080/compiler/ it gave me this error about No such file or directory: './configure':

I downgraded OMEdit to 1.14.1, rebuilt the FMU and tried http://localhost:8080/compiler again and it gave me a similar error:

Thanks in advance for any thoughts or advice.

p.s. also if it helps others, the Tools > Options > FMI menu to set the solver for co-simulation is only available from OMEdit 1.18.1, it is not present in 1.18.0.

I added a couple of lines to /home/vagrant/Bodylight.js-FMU-Compiler/compiler/openmodelica.sh before the call to emconfigure ./configure:

cd "$fmu_dir/sources"
cp ./configure.ac ./configure
chmod 777 configure  # needed otherwise it complains about "Permission denied"
emconfigure ./configure \
    CFLAGS='-Wno-unused-value -Wno-logical-op-parentheses' \
    CPPFLAGS="-DOMC_MINIMAL_METADATA=1 -I$sources_dir/fmi -I/usr/local/include"

It now errors with:

failed: [Errno 8] Exec format error: './configure'

[AJamesPhillips]

I notice at the top of configure.ac it says "Process this file with autoconf to produce a configure script."

[AJamesPhillips]

I ran sudo yum install autoconf followed by autoconf ./configure.ac (inside the VM) but it errored with:

/usr/bin/m4:configure.ac:179: cannot open `../../../../m4/lapack.m4': No such file or directory
autom4te: /usr/bin/m4 failed with exit status: 1

[AJamesPhillips]

I don't understand yet how and where the configure.ac gets generated or why it is not already converted to configure. I assume this is something wrong that I have done?

Hi, thanks for reporting. Sorry, the script to compile FMU from OM needs substantial revision as I discovered other subsequent issues, and did not find a solution now.

If you're stuck just with compiling MO to JS, I've tried to create some LorenzAttractor model and exported it from Dymola and compiled to FMU with source codes. The model, fmu and demo as web app can be downloaded from

The demo web app screencast from index.html:

[AJamesPhillips]

Amazing, thank you Tomas! I'm just using the Lorenz Attractor as a minimal test case to prove OM (Open Modelica Edit) -> JS works. I want to run much large more complex models. Thanks for letting me know it's not functional yet. I don't have much experience of OM or WASM but I am an experienced software engineer so if you have a list of questions / tasks you think I could help with to get this repo to convert FMUs from OM then please share with me and I will do my best to help. I'd love to see this library working for them.

I can see creative-connections/Bodylight.js-FMU-Compiler#4 but I assume the fixes you are referring to are only needed in this repo?
I don't have access to Dymola yet otherwise I would use that instead of OM.

[TomasKulhanek]

Hi, I've tested on a clean VM (built from fresh sources) - instead of my dirty development VM. And I have following suggestion:

1. the OM you probably use is on Windows system - it creates FMU with source codes and configuration to be built on Windows system. The Bodylight.js-FMU-Compiler expects FMU with source codes and configuration prepared for Linux system. Unfortunatelly we did not stress it out, that FMU's from openmodelica needs to be generated on linux system. Probably this might be somehow configured in OM on Windows platform too. The compilation FMU-JS fails obviously on it. I suggest to use OM inside VM to create FMU.

2. I did some changes in compiler/openmodelica.sh script which fails on some other subsequent errors based on FMU with sources generated from OM 1.19.x. This workaround suppress the error of missing __stop_em_asm. I'm not sure whether it is critical, but quick test shows that FMU-JS works and that this JS seems to be fair stable. So I suggest to do git pull inside Bodylight.js-FMU-Compiler directory inside VM.

Any contribution to openmodelica.sh script to fix compilation with CVODE will be very appreciated creative-connections/Bodylight.js-FMU-Compiler#4d :-)

3. I also did fix the component fmu to be able to detect and initialize JS of FMU from OpenModelica correctly. Seems that its working now too. this will be shortly in some future bodylight-components release.

Updated demo at https://filedn.com/lHGc7w3H4jOpIe46u1nPt57/LorenzAttractor/LorenzAttractorHTMLExport.zip

If I use OMEdit on Mac to produce the FMU and use the Bodylight Compiler from inside this virtual machine (using Vagrant and VirtualBox on Mac) then it compiles something that seems right (I'm running into an error now trying to get the Editor to produce a working example similar to the one you've kindly attached above. I'm getting a fmi.js?4fc8:699 error catched during fmu step RuntimeError: abort(Assertion failed: Cannot call unknown function LorenzAttractor_fmi2Instantiate, make sure it is exported) error).

I appreciate the original problem was with running the compiler with an FMU which was produce from the Windows OMEdit. Shall we leave this issue open or would you rather we close it and direct people to using OMEdit from a Mac / Linux or from inside a linux virtual machine?
