TableTest not working under Win32 again

[Rüdiger Franke]

This issue had been solved 9 months ago in #4773 and re-appears in a different form now. The example is:

model TableTest
  extends Modelica.Blocks.Tables.CombiTable2D(
      table = [0.0,   1.0,   2.0,   3.0;
               1.0,   1.0,   3.0,   5.0;
               2.0,   2.0,   4.0,   6.0]);
  annotation(uses(Modelica(version="3.2.2")));
end TableTest;

FMI export from OMEdit under Win32 raises now (Cpp runtime selected):

g++ -shared -o TableTest.dll OMCppTableTestCalcHelperMain.o -L"C:/OpenModelica1.13.0-dev-32bit//lib//omc/cpp"  -Wl,--no-undefined -lOMCppSystem_static -lOMCppMath_static -lOMCppModelicaUtilities_static -lOMCppFMU_static -lOMCppNewton_static -lOMCppDgesvSolver_static -lOMCppExtensionUtilities_static -L"C:/someworkdir" "-LC:/OpenModelica1.13.0-dev-32bit//lib//omc" "-LC:/OpenModelica1.13.0-dev-32bit//lib/" "-L%APPDATA%/.openmodelica/binaries/TableTest" "-LC:/someworkdir/Resources/Library/mingw32" "-LC:/someworkdir/Resources/Library/win32" "-LC:/someworkdir/Resources/Library" -lModelicaStandardTables -lModelicaIO -lModelicaMatIO -lzlib "-L%APPDATA%/.openmodelica/binaries/Modelica" "-LC:/OpenModelica1.13.0-dev-32bit/lib/omlibrary/Modelica 3.2.2/Resources/Library/mingw32" "-LC:/OpenModelica1.13.0-dev-32bit/lib/omlibrary/Modelica 3.2.2/Resources/Library/win32" "-LC:/OpenModelica1.13.0-dev-32bit/lib/omlibrary/Modelica 3.2.2/Resources/Library" -lOMCppModelicaUtilities_static  -lOMCppDgesv_static -static

Attempting to manually add -lz -lhdf5 (as done for the simulator), yet another linker error comes up:

The additional link dependency to -lsz cannot be fulfilled (a misconfiguration of the static libhdf5.a?).

It is generally redigulous to have that many link dependencies for such a simple Modelica model.

[Adrian Pop]

The linking should be with: -lhdf5 -lz -lszip

[Adrian Pop]

These are defined here:
​https://github.com/OpenModelica/OMCompiler/blob/master/Compiler/runtime/omc_config.h#L102

[Rüdiger Franke]

What about -lzlib that is linked so far? Should it be replaced? Is there a difference between Windows and Linux?

[Adrian Pop]

We don't link with -lzlib on Windows / mingw. For mingw we have hardcoded lib flags in omc_config.h as the environment does not change.

I don't really know how it is on Linux. I think that configure for the MSL sources finds the needed flags, but I'm not sure.

[Martin Sjölund]

For Linux it's a shared library, so no additional flags are needed
