I am trying to run mixed integer quadratic programming by calling Cplex (122version) from Matlab using Mex function. When I try in matlab : mex miqp_cplex.c, following type errors occurred.
Creating library C:\Users\maskamal\AppData\Local\Temp\mex_3XVWAG\templib.x and object C:\Users\maskamal\AppData\Local\Temp\mex_3XVWAG\templib.exp
miqp_cplex.obj : error LNK2019: unresolved external symbol __imp_CPXcloseCPLEX referenced in function miqp

C:\PROGRA~1\MATLAB\R2011A\BIN\MEX.PL: Error: Link of 'miqp_cplex.mexw64' failed.
Since it fail to locate "ilcplex\cplex.h", I add full path
include "C:\ILOG\CPLEX_Studio_AcademicResearch122\cplex\include\ilcplex\cplex.h" and I guess problem is related to cplex.h and linking with library.
Any hints to solve my problem are welcomed.
I could solve it partly. I could compile by adding the path of library with mex command. However, when I run the mex file: miqp_cplex it says:
Invalid MEX-file 'C:\Users\maskamal\Documents\MATLAB\MexCplex80\miqp_cplex.mexw64': 指定されたモジュールが見つかりません。(translation from japanese: indicated module is not found)

Some, but not all:
error LNK2019: unresolved external symbol PARDISO_CHKMATRIX_Z referenced in function GCS_SYSTEMSOLVE_mp_PARDISOSPARSESOLVER
error LNK2019: unresolved external symbol PARDISO_CHKVEC_Z referenced in function GCS_SYSTEMSOLVE_mp_PARDISOSPARSESOLVER
error LNK2019: unresolved external symbol PARDISO_PRINTSTATS_Z referenced in function GCS_SYSTEMSOLVE_mp_PARDISOSPARSESOLVER
The PARDISO solver call itself works fine. Actually, the subroutine calls are made in a project which itself can be compiled correctly. It is an exe project (a unit test project) that makes calls to that lib that pops up these linker errors.
I am using Intel Parallel Studio 2017. According to the Intel Linker Tool, everything should be in good order, although apparently I must be missing something.
all.
I’m compiling Ipopt-3.9.3 in Windows 10 & Visual C++ 2010 Express.
I’ve built the projects of libCoinBlas, libConHSL, libCoinLapack as well as libIpopt, and generated libCoinBlas.lib, libCoinHSL.lib, libCoinLapack.lib as well as libIpopt.lib in the correct paths but with some warnings.
While when I tried to build the projects of IpoptAmplSolver and hs071_cpp, there exists the following fatal errors.

Is there anyone who can kindly tell me how should I deal with it?
Thank you very much for your attention, and I’m looking forward to your kind aid.
Finally, I've solved this problem which is due to the undefined functions. I think my case is about a released software package rather than some specific procedure code, hence, it's a little different and relative simple.
Without knowing the specifics of the libraries you are using, I recommend that you try the following to deal with this error:
The error tells you that the linker is missing code for some function calls. This probably means that a library file is not found. Make sure that the linker can find all needed lib files. Check the property pages. Under the Linker->General->Additional library directories, make sure that the directories where your lib-files are located are present and under Linker->Input->Additional dependencies, make sure that the the lib-files are listed. Also make sure that the parameters are present for the different Configurations.
If this still does not help, check if your libraries depend on other libraries. These should be mentioned in the documentation of the libraries you are using.
I've not built this, but here's what I would try from the start. From what you've said, you've compiled the .lib files that it links against and it's failing during linking.
So here are your options...
1) You've either missed a .lib file in the input list for the linker.
2) The actual .lib file doesn't contain the symbol that the linker needs (you can check this by dumping the symbols of the .lib file)
3) Your .lib file is compiled with either the wrong platform than what you're linking with or with the wrong type ie. release/debug.
4) The symbols in your lib are decorated because you're compiling as C++ instead of C, or visa-versa.
If you go through the above steps above, I'm pretty sure you'll find your problem, but you've not really given enough information to properly answer your question. Personally, I'd have a guess that you're compiling C as C++ or you've got the wrong platform type set for one of your lib files.
Thank you all very much for your patient and detailed advices that inspired me, and I finally find out that I should add some C files which define the necessary functions into my project. The detailed solution is as follows.
For example, I want to eliminate
5>dlarf.obj : error LNK2019: unresolved external symbol _iladlr_ referenced in function _dlarf_
5>dlarfb.obj : error LNK2001: unresolved external symbol _iladlr_
Step 1: Run
f2c iladlr.f
In the Visual Stuido Command Prompt and generate iladlr.c.
Step 2: Add iladlr.c to my project.
Step 3: Rebuild.
Finally, everything goes well.
I'm in the process of converting 32bit project to x64. In most cases it just means appending 64 to library paths (and eventually building those libraries for x64). Now I assume all libraries are already ready and the code is also x64 compatible. But I keep getting errors for boost zlib library, like these:
error LNK2019: unresolved external symbol inflateEnd
error LNK2019: unresolved external symbol inflate
error LNK2019: unresolved external symbol inflateInit_
error LNK2019: unresolved external symbol deflateEnd
error LNK2019: unresolved external symbol deflate
error LNK2001: unresolved external symbol "int const boost::iostreams::zlib::default_compression"
error LNK2001: unresolved external symbol "int const boost::iostreams::zlib::deflated"
error LNK2001: unresolved external symbol "int const boost::iostreams::zlib::default_strategy"
I enabled verbose mode for linker (in MS Visual Studio you do this by adding /VERBOSE:LIB to additional linker options). Thanks to that, I can see this output line:
Searching .\..\..\libs\boost145\stage\lib64\libboost_zlib-vc100-mt-gd-1_45.lib
That would imply that the library was found in the boost145\stage\lib64. So what should I be looking for now?
One strange thing is that file that defines the first group of missing symbols (those that are not within boost) has header files within the project, zlib.h and zconf.h. Maybe this is some hint? The zlib.h defines external symbols as:
ZEXTERN int ZEXPORT inflateEnd OF((z_streamp strm));
Obvious question is: where the hell is lib file for this header file?
I had the same issue, to resolve the errors I download the source from zlib and built the x64 dlls/libs locally. There were a couple issues with solution file downloaded, fixes are described below.
Zlib 1.2.8 source code: http://zlib.net/zlib128.zip

I'm new to libsvm and matlab. I have downloaded libsvm 3.17 from the web site and trained my dataset using Matlab. I wanted to save the file and I used svm_savemodel.c which refused to compile in matlab. This is the message that I get

I have included svm.h, mex.h, svm_model_matlab.h but it refused....

I'm trying to create a GLFW project, but I'm getting LNK2019 errors with the basic setup.
I've downloaded the latest binary (glfw-3.0.bin.WIN32.zip) to a folder.
I've created a new, empty console project.
Within VC++ Directories, I've added the following line to include directories:
C:\C++Libraries\glfw-3.0.bin.WIN32\include
I've added the following line to the Library Directories:
C:\C++Libraries\glfw-3.0.bin.WIN32\lib-msvc110
I've linked the following libraries:
opengl32.lib, glfw3.lib, glfw3dll.lib
From the latest tutorial, I paste into my project (no visible syntax errors) to test, but I get four LNK2019 errors after trying to run it.
Here are the errors:

You need to link in at least winmm.lib for timeGetTime. The joystick code is probably in there to.
