Missing ModelicaExternalC.dll in Modelica #2
Comments
|
The library should work out-of-the-box with Dymola. ModelicaExternalC.dll (and in fact all DLLs) is not required by Dymola. Only ED_XMLFile.lib and expat.lib from the library and ModelicaExternalC.lib from the Dymola installation are needed for linking an executable of XMLTest1. |
|
That's what I thought should happen. However, I get the error message above when I use version 1.0.2 of ExternData. |
|
Did you open package.mo in Dymola? What happens if you delete all DLLs from the Library dirs? |
|
You must not use ExternData\Resources\thirdParty\ITI\win32\ModelicaExternalC.lib with Dymola. This is only for building the DLLs for SimulationX from ITI. Dymola provides its own ModelicaExternalC.lib. |
|
Deleting all of the DLL files from the ExternData Library folders seems to have fixed the problem. The simulations run and I no longer get the error message. Thank you for your help and your quick responses. |
|
Glad that it works for you. But strange, I thought I checked this. I'll try to reproduce it next week with Dymola 2015 and 2016. I'll leave this issue open meanwhile. |
|
Actually I cannot reproduce the problem you mentioned with Dymola 2016. I downloaded ExternData 1.0.2 from the releases, extracted it to an empty directory and opened package.mo in Dymola 2016. The example models work out of the box. |
|
I can confirm this issue exists. Did a fresh clone, then tried to run XMLTest1 with Dymola 2016.

|
@thorade Thank you for reproducing the issue. If I only would know what goes wrong here? Do you have any clue (since you are an experienced Dymola user)? |
|
I believe it might be related to another issue I once encountered: |
|
Do you use MSVC or MinGW compiler? In my case it is MSVC. |
|
In case of MSVC the linker option |
|
I tried Visual Studio 2013 Community Edition, all examples have the same error. Where would I specify the linker option and where can I find the output? |
|
Please set set LINK=%DYMOLALINK% /stack:0x500000 /NODEFAULTLIB:LIBCD /NODEFAULTLIB:LIBC /NODEFAULTLIB:LIBCMT /OPT:NOREF %liblink% %libdsLib% %DELAYARG1% %DELAYARG2% dymosim.obj %EXTRALIB% to set LINK=%DYMOLALINK% /VERBOSE:Lib /stack:0x500000 /NODEFAULTLIB:LIBCD /NODEFAULTLIB:LIBC /NODEFAULTLIB:LIBCMT /OPT:NOREF %liblink% %libdsLib% %DELAYARG1% %DELAYARG2% dymosim.obj %EXTRALIB% Please run the translation again and watch the output in the Dymola log. |

OK, I changed that line and here is the complete content from the buildlog.txt: |
|
Thanks. Looks OK though since ED_XMLFile.lib and expat.lib are linked as expected. Need to check the linker warning about the imports. Oops!! This is the problem: ED_XMLFile.dll must not be there. |
|
OK, I will do that. |
|
Yes, indeed. The link instruction (line 197 of build.bat) contains this The reason why there are both ED_XMLFile.dll and ED_XMLFile.lib in Resources\win32 is simple. This way the lib should work out-of-the-shelf with SimulationX and Dymola (on Win). SimulationX requires the DLL only and Dymola the LIB. |
|
I'll rename ED_XMLFile.dll to ITI_ED_XMLFile.dll and will release a new version soon. |
|
Dependecy Walker gives following warning for dymosim.exe: But I did not yet find which module it is. |
|
Yes, now it works out of the box! |
|
Thanks. |
|
Thanks! |
|
Sure. Tell me if you see improvement. |
Where previously only
```xml
<root>
<table>[0,0;0.5,0.25;1,1]</table>
</root>
```
worked for arrays, now also
```xml
<root>
<table>
<row>0,0</row>
<row>0.5,0.25</row>
<row>1,1</row>
</table>
</root>
```
or even
```xml
<root>
<table>
<val>0<val>
<val>0<val>
<val>0.5<val>
<val>0.25<val>
<val>1<val>
<val>1<val>
</table>
</root>
```
work.

Argh, commit links should go to #3. |
I was excited to see this code available, however I get the following error when I load the Modelica code into Dymola and run a simulation on the XMLTest1 model:
The program can't start because ModelicaExternalC.dll is missing from your computer. Try reinstalling the program to fix this problem.
I can find ModelicaExternalC.lib, but not the dynamic library. Do I need to to change something in the ExternData code in order for it to look for the static library, not the dynamic library?
System specifics:
Windows 7 Enterprise SP1
Dymola 2015 and 2016 32-bit and 64-bit versions
