<div>Hi Andy,
<br />
<br />
The linker error concerning the missing main method was due to a wrong solution setup of the Fortran90FullExample in
VS.
<br />
The CMakeLists file provided generates only one single (C++) project in VS, which means all .f90 files will be ignored
by the compiler (it's impossible to have a single Fortran/C++ mixed language project in VS).
<br />
To solve this I had to configure the CMakeLists file to create a library from FECxxAdaptor.cxx and link it with the
Fortran90FullExample.
<br />
<br />
Other linker & compiler errors occurred with regards to mpi:
<br />
1) the target_link_libraries command in the CMakeLists file links ${MPI_Fortran_LIBRARIES} to the fortran
project,
<br />
but it forgets to link with msmpifec.lib (see also:
http://public.kitware.com/pipermail/cmake/2016-February/062861.html).
<br />
2) The specification of an include directory (containing header mpifptr.h) was missing.
<br />
<br />
Another problem arose when it comes to the the by hand name mangling for fortran in FECxxAdaptor.cxx.
<br />
To get rid of that I introduced function interfaces in the FEFortranAdaptor.f90 file and now it works independently of
the Fortran compiler used.
<br />
<br />
Now, there are only five remaining linker errors as shown below:
<br />
<br />
LNK2019: unresolved external symbol COPROCESS referenced in function TCP_mp_TESTCOPROCESSOR
FEFortranAdaptor.obj
<br />
LNK2019: unresolved external symbol COPROCESSORINITIALIZEWITHPYTHON referenced in function MAIN__
FEDriver.obj
<br />
LNK2019: unresolved external symbol COPROCESSORFINALIZE referenced in function MAIN__
FEDriver.obj
<br />
LNK2019: unresolved external symbol NEEDTOCREATEGRID referenced in function TCP_mp_TESTCOPROCESSOR
FEFortranAdaptor.obj
<br />
LNK2019: unresolved external symbol REQUESTDATADESCRIPTION referenced in function TCP_mp_TESTCOPROCESSOR
FEFortranAdaptor.obj
<br />
<br />
In the ParaViewCatalystUsersGuide_v2 the missing symbols appear to be declared in CAdaptorAPI.h and CPythonAdaptorAPI.h
(but NEEDTOCREATEGRID),
<br />
but I can't just include them in the Fortran code.
<br />
<br />
Can you tell me how to resolve those missing references?
<br />
<br />
Best,
<br />
Thomas

<div>Hi Thomas,
<br />
</div>
I really don't know about this. Do you get the same behavior if you don't link with Catalyst? Can you create a simple
helloworld.f90 example that works?
<br />
</div>
Best,</div>

<div>Hi Andy,
<br />
<br />
I have changed both lines from coproc to main, but the error message remains the same.
<br />
<br />
Best,

<div>Hi Thomas,
<br />
</div>
If you change from coproc to main in the "program" and "end program" lines in FEDriver.f90 does that fix the problem?
<br />
</div>
I'm working on a fix for this but don't have access to any MSVS compilers.
<br />
</div>
Thanks,</div>
Andy</div>

<div>Hello,
<br />
<br />
I'm trying to compile the Fortran90FullExample using MSVS (Intel Fortran Compiler 2017 and Visual C++ 2015 compiler).
<br />
Doing so I'm getting following linker error:
<br />
<br />
Error LNK2019 unresolved external symbol main referenced in function "int __cdecl
__scrt_common_main_seh(void)" (?__scrt_common_main_seh@@YAHXZ) Fortran90FullExample.
<br />
<br />
Obviously, the source code doesn't contain a main method at all, since the entry point is given by the fortran program
in file 'FEDriver.f90'.
<br />
Nevertheless, I guess the compiler internally creates a main method, and the linker cannot resolve the reference due to
a name mangling problem, as there are different compilers involved. But I'm not quite sure about that, nor how to solve
it, at that matter.
<br />
<br />
Can you give me a hint how to solve that problem?
<br />
<br />
Kind regards,
<br />
Thomas</div>
