How to build this project? (jpeg lib) - windows

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:
1>.\ansi2knr.c(273) : warning C4013: 'exit' undefined; assuming extern returning int
1>.\example.c(116) : warning C4013: 'exit' undefined; assuming extern returning int

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.

------------------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:
Error 1 error LNK2005: __crtSetUnhandledExceptionFilter already defined in MSVCRT.lib(MSVCR110.dll) LIBCMT.lib(winapisupp.obj)

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.

Unresolved externals with statically built ffmpeg on Windows

I built ffmpeg 1.2.1 as a static lib - x64, debug. And I tried to open one of my older projects that links against it. After modifying some changed APIs and similar in my source, it compiled fine, but I have major problems with linking.
EDITED: the complete latest build output:
1>libavformat.a(mov.o) : error LNK2019: unresolved external symbol __imp__gmtime64 referenced in function mov_read_mvhd
1>libavutil.a(parseutils.o) : error LNK2001: unresolved external symbol __imp__gmtime64

1>libmingwex.a(lib64_libmingwex_a-mingw_get_codepage.o) : error LNK2001: unresolved external symbol __mingw_get_msvcrt_handle
What am I doing wrong? What am I missing here?
Does ffmpeg even work today on Windows platform as a static lib, or it becomes less functional on Windows with each new version?
First 8 errors could be solved by manually inserting
#define _CRTIMP
in some files. This will prevent incorrect use of declspec(__dllimport). We are building a static lib, not a DLL, so it shouldn't be there. I also tried using --extra-cflags='-D_CRTIMP' while running configure before building ffmpeg, but it brakes the build totally. So, manual way is the only way.
The last 2 errors are total bitch:
libmingwex.a(lib64_libmingwex_a-mingw_output_format.o) : error LNK2019: unresolved external symbol __mingw_get_msvcrt_handle referenced in function __mingw_set_output_format
1>libmingwex.a(lib64_libmingwex_a-mingw_get_codepage.o) : error LNK2001: unresolved external symbol __mingw_get_msvcrt_handle
I found these symbols in libmingw32.a (if I remember correctly). But, when I link it, I have conflicts with LIBCMTD.lib. Removing the LIBCMTD.lib creates tons of unresolved externals.So, I would say that today we are not able to build ffmpeg as static x64 lib on Windows. It was in a way expected, because each new version was less Windows friendly.

wxWidgets 2.9.4 built under Visual C++ Express 2010 gives unresolved external errors

I have been trying to upgrade to wxWidgets 2.9.4 over my old 2.8.12 and have run into problems. I compiled it without errors from the command line but when I try to use them in the program that worked just fine under the previous version I get unresolved externals. I cut it down to just a bare frame and TextCtrl object and it still does this (it's basically identical to one of the sample codes at the moment).
I tried the following commands to build the static libraries:
nmake -f makefile.vc SHARED=0 BUILD=release + nmake -f makefile.vc SHARED=0 BUILD=debug
nmake -f makefile.vc SHARED=0 MONOLITHIC=0 BUILD=release + nmake -f makefile.vc SHARED=0 MONOLITHIC=0 BUILD=debug
nmake -f makefile.vc SHARED=0 BUILD=release UNICODE=0 + nmake -f makefile.vc SHARED=0 BUILD=debug UNICODE=0
nmake -f makefile.vc SHARED=0 BUILD=release UNICODE=0 MONOLITHIC=0 + nmake -f makefile.vc SHARED=0 BUILD=debug UNICODE=0 MONOLITHIC=0
Note that I tried using them with both the recommended unicode and no longer supported non-unicode (changed the project properties in Configuration Properties->General accordingly). Also, I used multi-threaded DLL /MD and /MDd linking as recommended by the wxWidgets manual.
Edit: Tried using \MT and \MTd as well, same effect.
From all of the above I get the same linker errors listed below when compiling my application. Please advise me what to do because I have ran out of ideas...
Additionally, as a final resort I built the whole thing using the converted MSVS project from the ../build/msw folder but it gave me the same results.

All errors coming from libpng are due to not linking with wxzlib[d].lib, simply add it to the list of libraries in your project. Or use the recommended way to build wxWidgets projects with MSVC and use auto-linking by prepending -I$(WXWIN)/include/msvc to your compiler header files search path.
The rest of the errors (which you only get in debug build which is suspicious on its own) are due to a mismatch between ANSI and Unicode builds. I don't know which version do you use finally as you seem to have built all of them at one moment or the other but if you use the default build, then you need to have _UNICODE and/or UNICODE defined in your project options.
Finally, to avoid such build mismatches in the future, either do nmake -f makefile.vc clean or use different build directories by using unique COMPILER_PREFIX for each build in the future. This is really not rocket science, you just need to avoid confusing yourself by doing too many things at once. Good luck!
Go to your project's settings and change General -> Character Set property accordingly. If you compiled the wx libs with UNICODE=0 (however recommended value is 1) then you need to use Multi-Byte Character set. If compiled ith UNICODE=1 then set that property to Unicode
As for runtime libs, if you compiled with SHARED=0 then in your project settings you will need to use C++ -> Code Generation -> Runtime Libraries property with 'Multi-Threaded Debug' and 'Multi-Threaded' for Debug and Release build accordingly.
The easiest way is to build wxWidgets libs from Visual Studio (there is a build/msw folder which contains solution file for VS2010) and in your project set the same properties as wx libs projects have.
I had this problem as well. I solved it by changing the setting in:
C/C++ | Language | Treat WChar_t as built in type
to Yes.

Does any one know an easy way to fix the followoing errors:

1>matrixmul.cu.obj : error LNK2019: unresolved external symbol __imp_cutDeleteTimer referenced in function main
1>matrixmul.cu.obj : error LNK2019: unresolved external symbol __imp_cutGetTimerValue referenced in function main
1>matrixmul.cu.obj : error LNK2019: unresolved external symbol __imp_cutStopTimer referenced in function main
1>matrixmul.cu.obj : error LNK2019: unresolved external symbol __imp_cutStartTimer referenced in function main
1>matrixmul.cu.obj : error LNK2019: unresolved external symbol __imp_cutCreateTimer referenced in function main
1>matrixmul.cu.obj : error LNK2019: unresolved external symbol __imp_cutReadFilei referenced in function main
1>matrixmul.cu.obj : error LNK2019: unresolved external symbol __imp_cutReadFilef referenced in function "int __cdecl ReadFile(struct Matrix *,char *)" (?ReadFile##YAHPEAUMatrix##PEAD#Z)
1>matrixmul.cu.obj : error LNK2019: unresolved external symbol __imp_cutWriteFilef referenced in function "void __cdecl WriteFile(struct Matrix,char *)" (?WriteFile##YAXUMatrix##PEAD#Z)
I've already tried adding the lib directories in:
C:\ProgramData\NVIDIA Corporation\NVIDIA GPU Computing SDK 4.0\C\common\lib\x64
C:\ProgramData\NVIDIA Corporation\NVIDIA GPU Computing SDK 4.0\CUDALibraries\common\lib\x64
Any help is apreciated
Those symbols look like functions from the "cutil" library which is included with the CUDA SDK, so you ought to make sure that Visual Studio is set up to link against cutil.lib.
