------------------UPDATE on 5/20/2019------------------
Following the suggestion by Gilles Gouaillardet, I have compiled my Fortran code with the /NODEFAULTLIB option. Now, I get fewer error messages:
Error 1 error LNK2019: unresolved external symbol __intel_new_feature_proc_init referenced in function MAIN__Test.obj
Error 2 error LNK2019: unresolved external symbol for_set_reentrancy referenced in function MAIN__ Test.obj
Error 3 error LNK2019: unresolved external symbol for_write_seq_lis referenced in function MAIN__ Test.obj
Error 4 error LNK2001: unresolved external symbol mainCRTStartup LINK
Error 5 error LNK2001: unresolved external symbol _fltused msmpifmc.lib(mpifbind.obj)
Error 6 fatal error LNK1120: 5 unresolved externals x64\Release\Hello.exe
Thank you.
------------------UPDATE on 5/17/2019------------------
So this is a response to the comment by Gilles Gouaillardet. This is only an update to my original question and not an answer.
My code is:
program mpisimple
implicit none
integer ierr
include 'mpif.h'
call mpi_init(ierr)
! print message to screen
write(6,*) 'Hello World!'
call mpi_finalize(ierr)
end
Just to recap, I am using Visual Studio 2012 and I have downloaded Microsoft-MPI v.10.0.
The following directories have been added to the "Additional Include Directories" for Fortran tab:
C:\Program Files (x86)\Microsoft SDKs\MPI\Include\x64
C:\Program Files (x86)\Microsoft SDKs\MPI\Include
The following directories have been added to the "Additional Library Directories" for Linker tab:
C:\Program Files (x86)\Microsoft SDKs\MPI\Lib\x64
These two files have been added as the Additional Dependencies:
"msmpifmc.lib" "msmpi.lib" <- I also tried these without the quotation marks.
Now I am getting different errors, which have to do with things already defined elsewhere:

------------------ORIGINAL POST------------------
I have been trying to compile a Fortran code that uses MPI but I keep getting "unresolved external symbol" errors related to MPI. How do I link MPI libraries properly?

The code also uses the Hypre library, developed at the Lawrence Livermore National Laboratory (hence those unresolved external symbols that begin with "HYPRE_"). When I first ran into this issue, I figured it had to do with filename mangling. However, when asked the Hypre library developers, the response I received was:
"These are MPI issues that don't have anything to do with name mangling in hypre (as far as I can see). The hypre library is looking for the C MPI routines while your main program is looking for the Fortran MPI routines, but it's finding neither. My guess is that you probably don't have the MPI library on your link line. You might try looking at some forums that discuss how to use MPI with Visual Studio."
I have tried several combinations of directory paths for "Additional Include Directories" and "Additional Library Directories" in Visual Studio, but that didn't help. The paths linked are:
C:\Program Files (x86)\Microsoft SDKs\MPI\Include
C:\Program Files (x86)\Microsoft SDKs\MPI\Include\x64
C:\Program Files (x86)\Microsoft SDKs\MPI\Lib\
C:\Program Files (x86)\Microsoft SDKs\MPI\Lib\x64
I should note that the code I have been trying to compile is actually an example file included in the Hypre library distribution, and thus I doubt that the issue comes from any coding error. Nevertheless, in case it helps. the code begins with
program ex5f
implicit none
include 'mpif.h'
All I am trying to do is to compile the code. I have found past posts discussing similar issues but they weren't 100% relevant to the issue I am having. Your help and time will be greatly appreciated.
Thank you.

I am trying to build ffmpeg on visual studio for ARM architecture. I run into following linker errors:
Error 58 error LNK2019: unresolved external symbol __imp__dclass referenced in function mov_read_tkhd avformat.lib(mov.o)
Error 59 error LNK2001: unresolved external symbol __imp__dclass avformat.lib(thp.o)

Error 61 error LNK2001: unresolved external symbol __imp__dclass avutil.lib(eval.o)
What is __imp__dclass and where it is defined in Visual Studio / FFMPEG?
I get the following when I do "dumpbin /symbols mov.o"
22D 00000000 UNDEF notype External | __imp__dclass
Any ideas?
This particular issue was due to missing isnan and isinf methods in FFMPEG. There was a problem in bringing math.obj and float.obj dependencies.

Can you tell me pls if i'm missing anything here?
I followed the guide in the pdf documentation, and also i've read:

I'd be grateful for any kind of help.
I had the same issue. Make sure you are compiling to the OS, not the chip. If the OS is 32-bit, use the 32 bit compile/link options found here, if the chip and OS are 64-bit, follow the instructions for the 64-bit entry:
https://websmp230.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=1056696
Edit: im now using http://code.google.com/p/jpeg-compressor/ so i dont care about making this work anymore.
I downloaded the http://ijg.org/ source code, i tried to build it as a DLL file.
This is farthest i could build until i went into dead-end.
I noticed there was some .c files which i had to delete, but i dont know if i deleted the correct ones, there was at least these files jmemmac.c and jmemdos.c which i figured i dont need. I had to delete jmemmac.c because i compile on windows, but it gave more errors so i kept deleting those useless files, but now i dont know what to do anymore.
Here are all the errors i got when building:

Ok, if you're compiling a DLL, you generally don't want any "main" functions. I assume the source files referencing a a function called "main" or "_main" are examples of how to use the library, so it should be save to get rid of those.
In jmemmac.c, there is a function called "jpeg_open_backing_store", which is one of the unresolved external symbols jmemmgr is complaining about. The function appears to have platform-dependant calls, such as the "FindFolder" function for mac.
The only thing I can think of to do is to study jmemmac.c, jmemdos.c and jmemansi.c and rewrite those functions so they will work on a windows platform.
Oh, and as for "exit" being undefined, include "stdlib.h", as it defines the exit function.
Well, here's a nice obscure one. I'm trying to compile the latest open transport tycoon source in Visual Studio 2005. (It's a C++ app that uses zlib, dx8 and a few other fairly common libraries).
I get a few linker errors to do with the freetype dependencies:
Error 1 error LNK2001: unresolved external symbol #FT_Done_Face#4 fontcache.obj
Error 2 error LNK2001: unresolved external symbol #FT_Load_Char#12 fontcache.obj
Error 3 error LNK2001: unresolved external symbol #FT_Init_FreeType#4 fontcache.obj

Error 7 error LNK2001: unresolved external symbol #FT_Render_Glyph#8 fontcache.obj
Error 8 error LNK2001: unresolved external symbol #FT_Set_Pixel_Sizes#12 fontcache.obj
Error 9 fatal error LNK1120: 8 unresolved externals ..\objs\Win32\Release\\openttd.exe
I've downloaded the most recent freetype stable and compiled it (also in VS2005), and put the ft2build.h and freetype include directories into my VS8/VC/include directory, and put the libfreetype2.lib library so compiled into my VS8/VC/lib directory. What could I be missing?
Thanks!
The # sign at the start of the mangled function names show that your fontcache.obj file is expecting these functions to have the __fastcall calling convention, which is unusual as the default calling convention is __cdecl. I suspect there's a mismatch somewhere in the compiler settings used to build the libraries and those used to build the application. See here and here for more information.
