anyone helps？Thanks！！

There's currently an issue on Windows, see this issue. Our library testing is done on Linux, so that's why it works there but not for you.

Thanks for your kindly reply, perost.
I see that this issue is under fixing now on GitHub here:  https://github.com/OpenModelica/OpenModelica/pull/8506
Could you please tell me when this fix can be present in the nightly-build 1.19 - dev released?
Thanks again!

Hopefully soon, but I can't really give an accurate estimate. But it's a very high priority issue.

Dear perost，

Hi Youth,

Can you please check if you have the file ModelicaExternalC.so somewhere in your /usr/lib folder? If not please try reinstalling OpenModelica. Otherwise we might have a faulty installer. I will check in the meantime.

I think the weird part is looking in /omc/ffi. The ffi directory doesn't exist for me. What OMC version was this on Linux?

> I think the weird part is looking in /omc/ffi. The ffi directory doesn't exist for me. What OMC version was this on Linux?

What version of omc do you have? If it is not a nightly build from a few days back the omc/ffi directory should not be there. Otherwise it should.

If it is missing for Youth then it is probably the package not including everything in /lib/x86_64-linux-gnu/omc/. Maybe it is including only /lib/x86_64-linux-gnu/*.a and /lib/x86_64-linux-gnu/*.so?

I did upgrade today, but maybe I forgot to use /usr/bin/omc. If you change any file installed, you need to update the installer or you will break everyone's Linux install... https://github.com/OpenModelica/OpenMod … ter/debian

Hi mahge,

The OM version is OpenModelica 1.19.0~dev-586-gbf2fb17, and I installed yestday.
I installed via:

echo "deb https://build.openmodelica.org/apt `lsb_release -cs` nightly" | sudo tee /etc/apt/sources.list.d/openmodelica.list

wget -q http://build.openmodelica.org/apt/openmodelica.asc -O- | sudo apt-key add - 

sudo apt update

sudo apt install openmodelica

And installed the libraries via:

installPackage(Buildings, "9.0.0");

installPackage(Modelica, "4.0.0");

I searched all my computer but no " ModelicaExternalC.so" was found.

That is exactly what I just said.

The problem apparently is that the debian package selectively picks some libs instead of adding the whole /lib/x86_64-linux-gnu/omc/ folder. Examples from the script:

# MSL-external

debian/tmp/usr/lib/*/omc/libModelica*

debian/tmp/usr/lib/*/omc/libzlib**

for now I will add it manually as everything else. At some point we need to change it so that changes can be reflected in the package without having to manually list libraries.

I searched all my computer but no " ModelicaExternalC.so" was found.

I see. The issue is from our side. The package did not include everything needed. We will update it today and you can try the nightly build tomorrow. Sorry for the inconvenience.

In the meantime you can use the nightly builds from about a week ago. They should work fine on Linux.

Dear mahge,

BTW, I tried the Nightly Built on Windows just now but still same Error saying:

Dear sjoelund.se,

Thanks very much for the rapid effort of you guys!!

Looking forward to tomorrow's Nightly Built!

Guessing from the error messages, I think the version you used does not include the new changes. The messages should be a bit different even if the library is not found (more directories listed).  I will see if it has indeed been built correctly.

Guessing from the error messages, I think the version you used does not include the new changes. The messages should be a bit different even if the library is not found (more directories listed).  I will see if it has indeed been built correctly.

You are right bro. I just copied the error msg from the first reply of this post I thought they are same but not.
I did tried the lastest night built on Windows and there is "Not Found library" error like what I post just now but not same.

We have now fixed the issues in

https://github.com/OpenModelica/OpenMod … 5b1e9e9a0d and https://github.com/OpenModelica/OpenMod … ts/pull/25

For both Linux and Windows installations. You should be able to download a new Windows build in about 3 hours. For the Linux ones you have to wait until tomorrow (or use a week old nightly build in the meantime).

Dear mahge,

I tested the nightly build this morning:

Windows:
version: OpenModelica-v1.19.0-dev-595-g2590823b62-64bit

"This application failed to start because of no Qt platform plugin could be initialized" Reinstalled but failed again...

Linux:
version: OpenModelica 1.19.0~dev-590-g0897872

Error: External function ‘ModelicaStrings_compare‘ could not be found in any of the given shared libraries:
  /usr/bin/../lib/x86_64-linux-gnu/omc/ModelicaExternalC.so

[/root/.openmodelica/libraries/Modelica 4.0.0+maint.om/Utilities/Strings.mo:121:5-121:80:writable] Error: Failed to evaluate function: Modelica.Utilities.Strings.compare.

Both failed...

Could you please tell me how could I install the nightly version a week ago on LINUX? I failed to find a way to install this version.

Thanks in advance!

Sorry for this. The Windows installer script fix I did yesterday broke the installer by copying a lot of the things needed in /bin into bin/ffi. I have now fixed the issue:
https://github.com/OpenModelica/OpenMod … 0c265c2dd9
and started a new nightly build.

The Linux builds where not finished when you tried, they start at 02:00 Stockholm time and take 4-5 hours to build. You can update now and try.
