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:
ibpsa/modelica-ibpsa#40
If I manage to fix it, I will report a solution here.

Do you use MSVC or MinGW compiler? In my case it is MSVC.

In case of MSVC the linker option /VERBOSE:Lib displays a list of found lib dependencies.

I tried Visual Studio 2013 Community Edition, all examples have the same error.
The fix suggested by jnangle works:
After deleting all dll files from ExternData\ExternData\Resources\Library\win32 the examples simulate.
This also means that my first idea for a fix was wrong, must be something else.
Where would I specify the linker option and where can I find the output?

Please set /VERBOSE:Lib in file build.bat of your "Dymola 2016\bin" install directory. Edit line 197 from
set LINK=%DYMOLALINK% /stack:0x500000 /NODEFAULTLIB:LIBCD /NODEFAULTLIB:LIBC /NODEFAULTLIB:LIBCMT /OPT:NOREF %liblink% %libdsLib% %DELAYARG1% %DELAYARG2% dymosim.obj %EXTRALIB% to

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.
from externdata.

commented on May 22, 2024
OK, I will do that.
As deleting the dlls from the Resources\Library\win32 directory seems to fix the problem, I would assume they are the problematic part!? Are they needed or would it be an option to deliver the library without dlls?
from externdata.
tbeu
commented on May 22, 2024
Yes, indeed. The link instruction (line 197 of build.bat) contains this DELAYLOAD: option. Since ED_XMLFile.dll and ED_XMLFile.lib have the same name this leads to the conflict.
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:
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.
But I did not yet find which module it is.

@thorade Can you please git clone again (to a new directory) and check simulation with Dymola again. Should be fixed by 26754cb.
