I'm trying to use the tesseract in visual studio 2013. I'm using "libtesseract302.lib" in the the linker -> Input (not "libtesseract302-static.lib") and everythings was OK, and it's compiled and run, but when I tried to use this code:
tesseract::ResultIterator* ri;
tesseract::ChoiceIterator ci(*ri);
I got five link errors like this:
Error 3 error LNK2028: unresolved token (0A000567)
"public: __thiscall tesseract::ChoiceIterator::ChoiceIterator
(class tesseract::LTRResultIterator const &)"
(??0ChoiceIterator#tesseract##$$FQAE#ABVLTRResultIterator#1##Z)
referenced in function "int __cdecl main(void)" (?main##$$HYAHXZ)
I think it's because I didn't use the static library, so I tried that, but I got many linking errors. I think that is due to the static library having been built before using vs2008 that I got from here.
Tesseract
So I'm trying now to compile the tesseract as static lib in vs2013. Will solve the issue, or should I try something else?

I have a Microsoft Visual 2010 project that runs fine in the Win-32 compilation setting. I am running on Windows 10. I am trying to use the x64 to build for 64-bit but that is when I encounter the LNK errors (examples below):
error LNK2028: unresolved token (0A00015D) "extern "C" unsigned char __cdecl
UcanDeinitCan(unsigned char)" (?UcanDeinitCan##$$J0YAEE#Z) referenced in function
"public: unsigned int __cdecl CAN::DeConfigDev(void)" (?DeConfigDev#CAN##$$FQEAAIXZ)
CAN.obj
error LNK2019: unresolved external symbol "extern "C" unsigned char __cdecl
UcanDeinitCan(unsigned char)" (?UcanDeinitCan##$$J0YAEE#Z) referenced in function
"public: unsigned int __cdecl CAN::DeConfigDev(void)" (?DeConfigDev#CAN##$$FQEAAIXZ)
CAN.obj
error LNK2001: unresolved external symbol __imp___glewGenBuffers Patient_GPU.obj
I've attempted to change the /clr function, as well as the calling convention (_cdecl ...) in an attempt to follow other solutions related to the LNK errors but neither has worked. Is there a different way to fix these errors, or get a better idea of what they actually mean? Any help would be greatly appreciated. Thank you so much!
You're probably linking UCAN static library from somewhere. You need to make sure that in 64bit configuration, you link to 64bit .lib file.
First thing to check is Additional dependencies config and check what libraries are linked into the project.
I work with Windovs and I need to build a static CLucene library. I downloaded the latest source code and build them into Visual Studio 2010 Project through CMake-gui 3.4.3. When building I used a flag BUILD_STATIC_LIBRARIES = true. I successfully built two libraries: clucene-core-statics and clucene-shared-static. However, when I run the test project cl-test-static occurs a lot of linker errors. The same thing happens when I add these libraries in another test project.
Error Example:
Error 1 error LNK2019: unresolved external symbol
"__declspec(dllimport) public: static wchar_t * __cdecl
lucene::queryParser::QueryParser::escape(wchar_t const *)"
(__imp_?escape#QueryParser#queryParser#lucene##SAPA_WPB_W#Z)
referenced in function "public: void __thiscall Main::Start(void)"
(?Start#Main##QAEXXZ) c:\Users\user\documents\visual studio
2010\Projects\TestClucene\TestClucene\Main.obj TestClucene
Does anyone have any experience in building static CLucene libraries?
I downloaded and compiled GraphicsMagick, 1.3.23, Q16, x64, StaticMT version. I had to convert the Visual Studio 7 solution generated by GraphicsMagick's build utility to Visual Studio 2015 format. I linked my project to CORE_DB_magick_.lib and CORE_DB_Magick++_.lib.
When the linker ran, it produced unresolved external symbols when linking InitializeMagick() and DestroyMagick()
1>wtd.lib(WebController.obj) : error LNK2019: unresolved external symbol __imp_DestroyMagick referenced in function "public: __cdecl Wt::WebController::~WebController(void)" (??1WebController#Wt##QEAA#XZ)
1>wtd.lib(WebController.obj) : error LNK2019: unresolved external symbol __imp_InitializeMagick referenced in function "public: __cdecl Wt::WebController::WebController(class Wt::WServer &,class std::basic_string,class std::allocator > const &,bool)" (??0WebController#Wt##QEAA#AEAVWServer#1#AEBV?$basic_string#DU?$char_traits#D#std##V?$allocator#D#2##std##_N#Z)
I can't understand why the symbols are not being linked. Any ideas?
Apparently, GraphicsMagick Static versions do not link properly.
What is your project type? I had a similar problem when trying to link the GraphicsMagick libraries to a DLL.
The clue here is that __imp is the function decoration for DLL imports, so you're trying to link with DLL functions.
The problem is that the header magick/common.h, when linked to a DLL project, reads the current configuration of the Visual Studio pre-processor environment to determine which mode the library is in, which is obviously wrong if you're trying to link static libraries into your DLL, for example. In this case, it defines MagickExport to __declspec(dllimport).
AFAIK this is a bug in the library. For proper static build support, magick/common.h needs to do something like read information from the magick/magick_config.h to determine what mode the library was actually built in and define MagickExport appropriately.
Since your library is statically linked, you can fix this by commenting out everything in the define:
#if defined(MSWINDOWS) && !defined(__CYGWIN__)
and replacing it with:
#define MagickExport
#define ModuleExport
#define MagickGlobal
I can't seem to get a very simple program to compile in Visual Studio 2013. My goal is to incorporate UHD into a C++ program (UHD Driver and Libraries for Windows). I downloaded and installed the Windows UHD package.Since the library also depends on Boost, I also downloaded the appropriate Boost library. After that, I wrote a quick test program in Visual Studio 2013:
#include "stdafx.h"
#include <iostream>
#include <uhd\usrp\multi_usrp.hpp>
#include <uhd\types\device_addr.hpp>
using namespace uhd;
int main(void)
{
device_addr_t hint;
device_addrs_t dev_addrs = device::find(hint);
system("pause");
return 0;
}
In case anyone is interested, this program should locate any USRPs attached to a host PC. I defined the appropriate include paths in Visual Studio: . .
To be clear, I included two paths to the header files:
C:\Program Files (x86)\UHD\include and C:\Program Files (x86)\boost_1_55_0
and one path to the library:
C:\Program Files (x86)\UHD\lib
When I wrote the above program, Visual Studio recognized the additional include files, recognized device_addr_t as a typedef, and didn't throw any errors. However, when I built the program, I received these errors:
Error 3 error LNK2019: unresolved external symbol "__declspec(dllimport) public: static class std::vector<class uhd::device_addr_t,class std::allocator<class uhd::device_addr_t> > __cdecl uhd::device::find(class uhd::device_addr_t const &)" (__imp_?find#device#uhd##SA?AV?$vector#Vdevice_addr_t#uhd##V?$allocator#Vdevice_addr_t#uhd###std###std##ABVdevice_addr_t#2##Z) referenced in function _main C:\Users\...\Documents\Visual Studio 2013\Projects\uhd_test\uhd_test\uhd_test.obj uhd_test

Error 4 error LNK1120: 3 unresolved externals C:\Users\...\Documents\Visual Studio 2013\Projects\uhd_test\Debug\uhd_test.exe uhd_test
I've encountered these errors before in other programs, but I was able to resolve them relatively easily; either I would misspell a crucial include, or there would be an issue with a template class. However, in this instance, I can't seem to resolve the issue.
Any constructive input would be appreciated.
NOTE: In addition to defining the library directory path, I've explicitly added the UHD library, and I receive the same errors.
I got your example working. Here's the software versions I used since you didn't mention much in your description:
Microsoft Visual Studio 2013
VC++ Redistributable Package for VS2013 (vcredist_x86)
UHD 003.007.002, VS2013, Win32
Boost 1.56, lib32-msvc-12.0 binary package
Here are the project configuration properties you need to set in your VS2013 applications:
C/C++ -> General -> Additional Include Directories
C:\local\boost_1_56_0
C:\Program Files (x86)\uhd\include
Linker -> General -> Additional Library Directories
C:\local\boost_1_56_0\lib32-msvc-12.0
C:\Program Files (x86)\uhd\lib
Linker -> Input -> Additional Dependencies
uhd.lib
I think the last step is what's tripping you up, good luck!
I followed exactly what David Greene said, and I ended up with the same errors. Eventually I figured out that I had downloaded the 64-bit UHD, but I was using Visual Studio 2013 Express, which was a 32-bit compiler. Downloading the 32-bit version of UHD for Visual Studio 2013 solved the problem. For anyone else having this problem, double check that the compiler matches which version of UHD you install.
I have successfully built the Boost.Log library on Windows 7 for VS 2010. When I tried to run the simplest example, my program could not find the symbols for Boost.System and Boost.Filesystem, and I got the 'undefined external symbol' errors. I have coped with that issue by manually including libboost_filesystem-vc100-mt-gd-1_48.lib and libboost_system-vc100-mt-gd-1_48.lib in the project.
Nevertheless, now I have another problem: while trying to build the "basic_usage" example for Boost.Log I get the error
error LNK2019: unresolved external symbol "private: void __thiscall boost::log_mt_nt5::sinks::basic_text_file_backend<char>::construct(class boost::filesystem3::path const &,int,unsigned __int64,class boost::function0<bool> const &,bool)"
How can I solve this problem?
I have found the solution!
The reason was that I've built the Boost.Log with the Boost.Filesystem v2, while it was supposed to built with v3. I have rebuilt it correctly and now it works perfectly.
