Unresolved external when using boost log - c++

I'm having problem while trying to use boost log. I'm getting following error message:

I'm not really sure what is wrong. The libraries are there, the linker finds them. Just not symbols in them. Any tips?

Ok, figured it out. Problem was, that boost was compiled with _WIN32_WINNT 0x0601 while I was building with 0x0501. Just changed mine to 0x0601 as well and it linked fine.

But this program or application you created works in windows 7 or more. It does not supports for Windows XP.
If you want to create application that supports for windows XP, then you can use BOOST 1.58 version.
This version is last which supports from Windows XP. Then later versions supports more than windows XP (i.e.)From vista only.

I build in the Debug and x64 configuration.
What am I missing? I thought vcpkg shall make life easier?
It seems to be a problem of the grpc package.
2nd part of the accepted answer of Linking gRPC on Windows for VisualC++ exactly fixed my problem.
I added #pragma comment(lib, "Ws2_32.lib") to my cpp-file and the problem was gone.
It also can be fixed like so (I've taken the screenshot from Unresolved external symbol LNK2019):

Why am I getting these linker errors with cinder and CodeBlocks?

I'm having a bit of trouble compiling a project of mine using Code::Blocks and llvm-clang on Windows 10. Here's some of the error msg as its waay too long to fit in fully, but all of what should be needed is in there.

I've linked cinder.lib, libEGL.lib, libGLESv2.lib, and libpng.lib
I don't see any reason why this should not be working.

I get error LNK2019 when I try to compile zeromq sources

I'm trying to compile the zeromq sources and I have the following error:
I'm using Visual studio 2013 update 4 / windows 7 x64
First of all I compile the libsodium library satisfactorily.
Then I link the libsodium header files directory path to additional dependencies and libsodium.lib to additional library directories. I also specify the name of library in additional dependencies.
I try to compile it under win32 architecture and x64 architecture but I get the same errors.
I know that a __imp prefix is used as a bridge to the function that I want to use so if I linked the libraries appropiately why do I get this error?

Thanks in advance.
You're probably compiling libsodium in a static way.
Try to compile it dinamically and link it again.
Such errors are also able to occur when you have a wrong set calling convention at your project.

I am a complete newbie in cpp and I would appreciate any help!
Thank you!

Googletest C++ unit testing linking error [duplicate]

This question already has answers here:
What is an undefined reference/unresolved external symbol error and how do I fix it?
(39 answers)
Closed 6 years ago.
I'm a beginner C++ programmer. I'm trying Google Test in Visual Studio 2012 and have problem starting a demo source code I got from internet.
int CompareChar(char* ch1, char* ch2)
{
if (ch1 == NULL || ch2 == NULL)
return 88;
return strcmp(ch1, ch2);
}
TEST(CompareCharTest, InputChar) {
// Expect equal
EXPECT_EQ(0, CompareChar("hello", "hello"));
// Expect not equal
EXPECT_NE(0, CompareChar("hello", "world"));
}
TEST(SampleClassTest, InputNumber) {
SampleClass sample(10);
EXPECT_EQ(1, sample.CompareValue(10)); // Expect equal
}
int _tmain(int argc, _TCHAR* argv[])
{
::testing::InitGoogleTest(&argc, argv);
int i = RUN_ALL_TESTS();
getchar();
return i;
}
So, when I try to build the code, it generates dozens of linking errors which I couldn't sort out. I tried to include .lib files in the property of the project but couldn't solve it.

I had the same issue. Make sure that in your test project's properties, you go into Project->Linker->General settings and add the msvc/Release directory to Additional Directories. Furthermore, under Linker->Input, add gtest.lib into Additional Dependencies. Then you should be good to go!
I know this post is old, but it could still help anyone out. A quick Google search for "LNK2019 unresolved external symbol "bool __cdecl testing::internal::IsTrue ..." as stated above gives this stackoverflow and several sites with the same answers.
For those that tried Oleg Vaskevich solution or similar and failed, try this. If you are using Visual Studio, C/C++ -> General -> Additional Include Directories and make sure that the gtest is included. Secondly, (which will likely be your answer), copy the gtest-all.cc in the gtest/scr/ folder and paste in your project directory (wherever your .cpp/.h files are saved), then go back to Visual Studio and include it in your project. You will have to unhide files/folders to view it. 'Include to project'.
I know that copying and pasting this isn't ideal for every project, but the point is to at least get it working and making sure this is the true problem and not something else.
Because I never complied my version, I never had any lib files to begin with.
