I am a newbie to Open Cascade.After building occt-7.3.0-vc14-64 with cmake with no error, i added inc/ in Include Directories and added win64/vc14/libd/ in Library Directories, then added only "include" in main.cpp. But after clicked debug button, i got link error as following:
Error LNK2019 unresolved external symbol "public: __cdecl
Standard_OutOfMemory::Standard_OutOfMemory(char const * const)" (??
0Standard_OutOfMemory##QEAA#QEBD#Z) referenced in function "public:
void __cdecl Standard_OutOfMemory::`default constructor closure'(void)"
(??_FStandard_OutOfMemory##QEAAXXZ)
What else should have be done?
Thanks for any help.
This error is that can't find lib that contain Standard_OutOfMemory.
Standard_OutOfMemory is a class in TKernel.dll, you should add TKernel.lib to project's Additional Dependencies, like on the image below:

I am trying to implement a module in UE_4.26 project where I am getting Linker Error like the following:
ChunkDemoGameInstance.cpp.obj: error LNK2019: unresolved external symbol "public: static int __cdecl
FChunkDownloaderDBWrapper::GetDatabase(class SQLiteDriver *)" (?GetDatabase#FChunkDownloaderDBWrapper##SAHPEAVSQLiteDriver###Z) referenced in function "public: void __cdecl

I was not getting this error earlier when I was compiling my code in VS2019 but now when I try to compile it gives the above error.
Can you update your post to include your Build.cs file for your module and your project? You need to make sure that you add your libraries to the module's build.cs file and in your project build.cs file you must add the module name as a module to be loaded by Unreal build tool during compile.
if (Target.Platform == UnrealTargetPlatform.Win32 ||
Target.Platform == UnrealTargetPlatform.Win64)
{
PublicSystemLibraries.Add("kernel32.lib");
}
Here's an example of adding the kernel32.lib file to be used during a build.
I've got a VC++ project, and I'm attempting to use the extension of the gumbo-query library, found here. This library wraps/extends Google's gumbo-parser found here. The following is the exact steps I've taken - I'm not very familiar with importing libraries, so I've done what I do to use the Boost libraries:
In Visual Studio (VS Community 2013), under the project settings -> Configuration Properties -> C/C++ -> General I have put the path to a folder that contains all of the source files from both of the projects linked above. Specifically, I placed the .c, .cpp and .h files from the src folder of both projects and referenced these in my projects settings as an include directory.
Following the example file for the project that extends Google's gumbo-parser (found here), I added these two lines to import the library:
#include "Document.h"
#include "Node.h"
At this point, my solution compiles fine. However, continuing to follow the example file, adding the first variable declaration:
CDocument d;
Causes a linker error, as follows:
1>Main.obj : error LNK2028: unresolved token (0A0003B7) "public: __thiscall CDocument::CDocument(void)" (??0CDocument##$$FQAE#XZ) referenced in function "private: void __clrcall MyApplication::Main::worker_DoWork(class System::Object ^,class System::ComponentModel::DoWorkEventArgs ^)" (?worker_DoWork#Main#MyApplication##$$FA$AAMXP$AAVObject#System##P$AAVDoWorkEventArgs#ComponentModel#4##Z)

1>..{omitted}..\MyApplication.exe : fatal error LNK1120: 4 unresolved externals
This error appears to occur no matter where I put a CDocument instantiation.
What can I do to rectify this? VS seems to think the includes are fine, and moreso when I put in CDocument d; it lights up to show it recognises the CDocument type.
As always, it's clear I've been a JS developer for too long. I really did need to compile a .lib file. Thank you to Christian for reminding me of this.
The original gumbo-parser project by Google includes a VS project. I opened this and compiled it, fixing all of the project settings problems so that I could import it into my project, which I did via the Configuration Properties -> Linker -> Input -> Additional Dependencies setting for my VS project.
Next, I added the extra source files from the wrapper library gumbo-query, where I had to fix a naming conflict between parser.h/parser.cpp from the original gumbo-parser project and the Parser.h/Parser.cpp file in the wrapper library. I also changed all references to #include <gumbo.h> to #include "gumbo.h"
Eventually, I got a gumbo.lib file containing both the original and the wrapper libraries, and this imported into my project and I now seem to be able to successfully use the functions.
I would like to use the features of QCustomPlot to draw some results from my openCV projects.
I didn't find a way to include QCustomPlot to my Microsoft Visual Studio 2010. I have included or course the cpp and h file into my project. But, I think what is still missing for me is regarding its linker and the additional dependencies (.lib file)

I searched for it but no results.
Where shall I download it?
It looks like you either didn't moc your cpp file or you simply forgot to compile and link against the moc generated .cpp file.
I have some link error problems when trying to compile using jrtplib and jthread on my simple project. The errors are:
Error 4 fatal error LNK1120: 3 unresolved externals C:\Users\Chicko\Desktop\tryout\Debug\tryout.exe

and here is my main program:

}
For your information, I do not import any header file from those libraries into my project. I use additional include libraries in the project setting and put `"..\jlib\jthread-1.2.1\src";"..\jlib\jrtplib3.8.2\src" (this is the folder where all the headers are stored). How do I fix this? Where should i put jrtplib.lib and jthread.lib? Please help...
Have you added jrtplib.lib and jthread.lib under your project linker options?
You can do this on the project property page under
"Configuration properties->Linker->Input->Additional Dependencies" and make sure that the directory that contains the lib files has been added to your library path: Either on the project properties
"Linker->General->Additional Library Directories"
or under the global VS settings (Doesn't apply to VC2010)
"Tools->Options" "Projects and Solutions->VC++ Directories->Library Files"
Under VC2010 you'll have to edit the property sheet of the project.
I see that it's a bit late to answer and I'm not so expert on Windows (I'm more a Linux user), but some day ago I've tried JRTPLIB on Windows and I had the same problem when I compiled the example in release mode and the lib in debug mode (I see that you use the debug mode). Hope it can help.
While trying to compile program, that uses zlib, i got following errors:
Error 1 error LNK2019: unresolved
external symbol _compress referenced
in function "void __cdecl
save_image_in_pakfile(class
std::basic_ofstream > &,struct
_IplImage *)" (?save_image_in_pakfile##YAXAAV?$basic_ofstream#DU?$char_traits#D#std###std##PAU_IplImage###Z) buffer_management.obj
Error 2 error LNK2001: unresolved
external symbol
_compress fern_based_point_classifier.obj
And two more same errors but related to uncompress function.
I use the vs2008 C++, and at the project properties I added in
C/C++ : Additional include directories the path to header files of zlib.
And at linker properties I added at additional dependencies:
zlibwapi.lib and zlibstat.lib files.
How to resolv the problem?
If I made some mistakes please show me them..
