There are several ways of handling with this:

1. Have a look in any of the generated *.log files. It might point you to the error.
2. Add getErrorString(); after the simulate command as it may give you additional info.
3. Run the script from the command line:
    > cd C:\OpenModelica1.5.0\testmodels
    > ..\bin\omc +showErrorMessages +d=failtrace sim_BouncingBall.mos

Post back here with what you find.

Cheers,

this is the result
it doesn't sound good for me

so ... I should format my pc and reinstall all the stuffs.

I think it's better

No. Do you by any chance installed a new version of MinGW?
OpenModelica distributes with MinGW 3.4.5 and if you install
another one it might be a problem.

As it worked fine before, is something that you did in the meantime.

Cheers,

Hm. I think I found what the problem is.

Here http://lists-archives.org/mingw-users/1 … c-6-0.html
it say that msvcrt.dll version less than 8 does generate these problems.

Somehow you ended up with an older (than version 8) msvcrt.dll in:
c:\windows\system32\msvcrt.dll

See if that is the case and try to install a newer one, i.e.:
http://www.microsoft.com/downloads/deta … laylang=en

Hello,

I have the same issue with Kubuntu 10.04 and Openmodelica 1.5.0 : all simulations failed!

I try the following command

The result is :

I have also a HDD with Windows OS (XP SP3) and the result is the same.

I note FONTE user is French (He start the message with "Bonjour"), like me. Do you think Regional or Local Settings could be a way to fix the issue (French have comma for decimal separator)?

Thanks for your help.

/usr/share/doc/omc/testmodels$ omc +showErrorMessages +d=failtrace

There's your problem. You do not have write rights to /usr/share/doc/omc. Only root does. OpenModelica really should put all files in a temp directory instead, but that's for the future
Swedish locale settings also use comma, and most of the developers are from there so I expect that's not the issue here.

Why you have the same problem in XP I don't know though. Maybe you installed OpenModelica in a path containing a space.

If copying the testmodels to a directory you can write to does not solve the issue, use the command checkSettings() in OMShell and paste the result.

I have copied and pasted sim_BouncingBall.mos in /home/thierry/tmp/ and I have run 'omc +showErrorMessages +d=failtrace  sim_BouncingBall.mos': same result than message #8.

Hereafter the result of checkSettings() command in OMShell-terminal.

>>> checkSettings()

record OpenModelica.Diagnostics.ImportantValues

    OPENMODELICAHOME = "/usr/",

    OPENMODELICALIBRARY = "/usr/share/omlibrary/modelicalib/",

    OMC_PATH = "/usr//bin/omc",

    OMC_FOUND = true,

    MODELICAUSERCFLAGS = "",

    WORKING_DIRECTORY = "/home/thierry/tmp",

    OS = "linux",

    SENDDATALIBS = " -lsendData -lQtNetwork -lQtCore -lQtGui -lpthread",

    C_COMPILER = "g++",

    C_COMPILER_RESPONDING = true,

    CONFIGURE_CMDLINE = "Configured 2010-07-03 11:00:11 using arguments: '--host=i486-linux-gnu --build=i486-linux-gnu --prefix=/usr --with-omniORB=/usr --with-static-lpsolve=/usr --with-sendData-Qt build_alias=i486-linux-gnu host_alias=i486-linux-gnu CFLAGS=-Wall -g -O2 LDFLAGS= CPPFLAGS='"

end OpenModelica.Diagnostics.ImportantValues;

OMC_PATH contains double slash "//". This is the problem?
No possibility to run checkSettings() with Windows.

Still... The actual code failing is:

file = fopen(filename,"w");

  if (file == NULL) {

    char *c_tokens[1]={filename};

    c_add_message(21, /* WRITING_FILE_ERROR */

      "SCRIPTING",

      "ERROR",

      "Error writing to file %s.",

      c_tokens,

      1);

    RML_TAILCALLK(rmlFC);

  }

So it really can't open files for writing in that directory. Can you manually create a new file (touch abc.txt) in that directory? Does root own some of the files that omc tries to overwrite?

The double slashes are not a problem. I have them myself.

I have made a mistake in a previous message. The error message is not the same when I copy BouncingBall.mo and sim_BoucingBall.mos under /home. See the result:

thierry@ACER-ASPIRE:~/camp$ ls

BouncingBall.mo  sim_BouncingBall.mos

If you run the executable manually, what does it say? And what does output.log contain (should be the executable output when called from simulate()).

Instruction non permise

thierry@ACER-ASPIRE:~/camp$ cat output.log

What does it means? It is the same with Windows.

French translation: "Instruction non permise" = "lllegal instruction"

Hmmm... what version of omc are you running (apt-cache show omc)?

You could probably also provide better information by running gdb:
gdb ./BouncingBall

> bt
< GDB shows a backtrace

I have seen in old forum a concern regarding SSE2 instruction. This could be my problem?

It might be that it's using SSE2, but any semi-modern machine has access to it. The simulation runtime does not look at CFLAGS from the configure script, but only the CPU that the system is running on. So it always builds with -msse2...

What is your "uname -m" output?

Anyway, I changed the runtime to use the architecture specified by CFLAGS.
If you want to test it, the build should be generated at 11:30 Paris time assuming nothing is broken.

Hereafter information needed:

thierry@ACER-ASPIRE:~/camp$ uname -m

i686

I have installed Openmodelica on a laptop with Windows, all work fine. But it would be nice if i can run Openmodelica with my machine.

I'll get on fixing the build on 32-bit tomorrow. I'll just need to check the build logs since it failed.

Yummy... 3 BouncingBall testcases spinning at 100% CPU on the build server.... That's what happens if you try to run simulations without -msse2 -mfpmath=sse

-msse is not good enough, because the dassl solver requires double precision. And the 387 floating point unit spins forever in simulations. Which means SSE2 is required to use OpenModelica on Linux.

Try omc_5833-1_i386.deb . It's compiled -msse -mfpmath=sse -ffloat-store, which should make the evil fortran code work correctly.

I have installed omc_5833-1_i386.deb. That's work fine. Thank you for your help.

Take care: Build repository don't work, I have downloaded and installed files manualy. I have already seen a post for this issue but bug continues.

What bug remains?

This one: http://www.openmodelica.org/index.php/forum/topic?id=76

Failed to fetch ..... size mismatch
when
sudo apt-get upgrade

Ah. Maybe you have some old downloaded files stored there (/var/cache/apt/archives). The problem is solved so it shouldn't happen again, but if you downloaded some of the bad files, they will still be there

Also, I'm assuming you are using stable or release. Then you won't be able to get the version compiled for SSE instead of SSE2 (until the release comes).

sudo apt-get clean
sudo apt-get upgrade

I am using nigthly build. The last version is omc_5840-1_i386.deb and all is OK.

I am starting to learn Modelica language.
