I successfully followed this tutorial on Linux: https://grpc.io/docs/quickstart/cpp/
( gRPC version: v1.28.1 )
Then I changed the helloworld.proto file and regenerated the grpc.pb.cc, pb.cc, grpc.pb.h, pb.h files.
Then I copied those files to a Windows 10 machine with Visual Studio 2017.
I used vcpkg to install grpc. (Holy cow, this step took 45 minutes... )
I started a new console project and added the helloworld example code.
The project magically seems to find the grpc include files.
But the IDE has 175 errors when I try to compile the project with the majority being E0145.
For example:
E0145 Member "google::protobuf::Any::kIndexInFileMessages" may not be initialized.
I tried turning off precompiled headers. But to no avail.
Does anyone have an idea how I can get this running ?

So I tried making a basic game on the console using screen buffers, I was able to create it and make a square move in the canvas, but for my next project I looked up a website with the ASCII characters and pasted a couple into a comment at the end of the c++ file, when I ran the file visual studio prompted:
I clicked yes and it didn't run anymore.
Also I recently have installed an extension for visual studio (before it didn't run, the extension works fine but I don't know if the extension may have caused this as I didn't tried running it with the extension downloaded and applied), when I open visual studio and open a file it says:
The last record in the ActivityLog xml file, has a type of error and it's description is:

I have Visual Studio 2017
So why does running the file (with the local windows debugger button) say that there were build errors? And how can I fix it?
When it prompts the build error, and I click no it usually shows the errors but in this case it doesn't, yes will just run the last "successful" build (although I haven't changed the file since I have finished it before this error message started popping up)
Also there is no error in my code as I was able to run it before the build error kept appearing and I haven't touched the file since(only now to show the problems are)
Thanks for your time! if anything was unclear because of my English, comment and I'll try to clarify it
I fixed the error by deleting ComponentModelChache folder located at:
C:\Users\%userName%\AppData\Local\Microsoft\VisualStudio\15.0
15.0 is the version of your visual studio so it varies depending on the version you're using, %userName% is a replacement for the user you're logged in as
I'm having a weird error after updating Visual Studio 2019 Community from v16.4.5 to 16.5. Even a fresh install of the engine will no longer build. I'm getting the errors listed below. The build doesn't fail until the end of compiling all modules:
Error C4800 Implicit conversion from 'ADODB::_Recordset *const ' to bool. Possible information loss UE4 C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.25.28610\INCLUDE\comip.h 311
Error C4800 Implicit conversion from 'ADODB::_Connection *const ' to bool. Possible information loss UE4 C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.25.28610\INCLUDE\comip.h 311
Error MSB3075 The command "..\..\Build\BatchFiles\Build.bat -Target="UE4Editor Win64 Development" -Target="ShaderCompileWorker Win64 Development -Quiet" -WaitMutex -FromMsBuild" exited with code 5. Please verify that you have sufficient rights to run this command. UE4 C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Microsoft\VC\v160\Microsoft.MakeFile.Targets 44
I have not changed or updated anything on the Unreal Engine-side of the code. This error occurs during a build of UE4.sln, sourced from Epic's github repo. The build doesn't fail until all modules are built (it fails at the end of the build).
Seeing as Microsoft doesn't have archives of installers for VS Community, only Enterprise and Pro, I'm kind of suddenly stuck here because I can't just uninstall 16.5 and reinstall 16.4.5 (which is the last working version I was on before the update).
I heard sometimes setting "treat warnings as errors" to false can help, but I don't see a way to do that in Visual Studio.
Any insight into this would be helpful, Thanks!
So, turns out something changed on VS2019's side in the update from 16.4.5 to 16.5, but the fix for UE4 can be found in this commit on the 4.25 branch. Confirmed that this solved my problem!
First Make a backup of your whole project (just copy it to somewhere else).
Afterwards delete the following folders in the project directory:-
.vs
Intermediate
Saved
you just need to delete the .vs folder to solve the problem. The rest are just for a quick refresh of your project.
Next open Unreal Engine 4, then under File tab click on Refresh Visual Studio Project. On completion try to compile again. This should solve your problem.
For those who facing the same problem, here is the solution.
Step 1:
open the file ADOSupport.cpp on [YourEngineSourceDir]\Engine\Plugins\Runtime\Database\ADOSupport\Source\ADOSupport\Private
Step 2:
go to line 255 and modify it
from if(ADORecordSet && (ADORecordSet->State & ADODB::adStateOpen))
to if(ADORecordSet != nullptr && (ADORecordSet->State & ADODB::adStateOpen))
Step 3:
got to line 328 and modify it from if( DataBaseConnection && (DataBaseConnection->State & ADODB::adStateOpen)) to if( DataBaseConnection != nullptr && (DataBaseConnection->State & ADODB::adStateOpen))
Step 4: Build the solution and enjoy!
You should add the new line of code, like on the video tutorial:
Arguments.Add("/wd4800"); // 4800: Implicit conversion from 'type' to bool. Possible information
https://youtu.be/KXIv4y51fyw
That fix me that issue.
I had the same issue, and this solved it:
File Path
YOURENGINEPASS\Engine\Source\Programs\UnrealBuildTool\Platform\Windows
File to change
VCToolChain.cs
After line 456 add the following line:
Arguments.Add("/wd4800"); // 4800: Implicit conversion from 'type' to bool. Possible information
I saw many many people ask this question and apparently there is no absolute answer to this question.
this happened for me when I uninstall my visual studio 2015 cause unreal 4.18 no matter I do use VS 2015 and I want to use 2017 and I saw some people solve this problem with uninstalling VS 2015.
when I uninstall VS 2015 receive this error when I want to create a new C++ project:

many peoples mention its relate to Windows SDK and there is windows SDK in installing if I add more let me know.
enter image description here
I thought if I install unreal 4.19 its maybe get fixed but it didn't.
it seens ue4 genrate C++ files for VS 2015.
enter image description here
I hope there is anyone known how to solve this problem and guide me how.
I fix it with downloading this cleaner form this link https://github.com/Microsoft/VisualStudioUninstaller/releases .
after that UE4 when you want to create new project sends a message and it says you don't have VS2017 don't panic just download the installer and modify it after that it downloading about 350 mg and after that, everything will get fixed.

I'm following this guide on building V8 but I am hitting some issues on the compilation step. I am running Windows 10 x64. I am trying to compile with options to embed the engine also.
Running the following command:
ninja -C out.gn/x64.release
Gives me this error:
ninja: Entering directory `out.gn/x64.release'
[1/471] LINK mksnapshot.exe mksnapshot.exe.pdb
FAILED: mksnapshot.exe mksnapshot.exe.pdb
C:/Workspace/depot_tools/win_tools-2_7_6_bin/python/bin/python.exe ../../build/toolchain/win/tool_wrapper.py link-wrapper environment.x64 False link.exe /nologo /OUT:./mksnapshot.exe /PDB:./mksnapshot.exe.pdb #./mksnapshot.exe.rsp
LINK : fatal error LNK1181: cannot open input file 'comdlg32.lib'
ninja: build stopped: subcommand failed.
Now I believe I have narrowed down the error to looking for the .lib files in the wrong directory. I have (had) multiple versions installed, so there were multiple folders in my Windows Kit install.
Windows Kits/10/Lib/10.0.16299.0
Windows Kits/10/Lib/10.0.15xxx.0
If I dragged and dropped the comdlg32.lib file from 10.0.16299.0 into the 10.0.15xxx.0 directory then the error changed to a LNK1181 error with a different input file. I did this a few times but I was unsure if this was going to cause issues with different versions and there was probably going to be a lot.
I uninstalled the 10.0.15xxx.0 version which left behind the folder I mentioned, so I removed that and after doing so I have started getting the LNK1181 error with a different input file (advapi32.lib I assume the very first file it can't find). This is how I came to the conclusion about the path being incorrect.
So I have tried a few things to change the path (I hoped just uninstalling the old version would fix it) such as:
Uninstalling the old version.
Going through registry entries to see if I can find an install path or something using that path, which I didn't. I did notice that there was still installation and data in the registry for the 10.0.15xxx.0 install, I might try deleting that from the registry directly as a last resort?
I have tried to explicitly set the path by setting <TargetUniversalCRTVersion>10.0.16299.0</TargetUniversalCRTVersion> in this file: C:\Program Files (x86)\Windows Kits\10\DesignTime\CommonConfiguration\Neutral\uCRT.props
I have never used Ninja before so I tried looking for a way to set some kind of lib-path in the command but couldn't really find anything.
I looked through the python scripts being executed to try and locate something to do with the libs path but couldn't see anything.
I would be grateful for any help and suggestions. Thanks.
You can try to compile v8 using Visual Studio as explained here: https://chromium.googlesource.com/chromium/src/+/master/docs/windows_build_instructions.md#using-the-visual-studio-ide
By running the following commands:
$ gn gen --ide=vs out.gn/x64.release
$ cd out.gn/x64.release
$ msbuild all.sln
You can see a full example here: https://github.com/phpv8/v8js/issues/272#issuecomment-262848754
Apparently this method is not officially supported anymore, but I had the same problem as you have and this solved the issue for me.
Note that after this I had another issue, the unit tests failed to be compiled due to a linking error, but I had the necessary libraries to use v8. So there may be deeper problem that is causing all of this that I'm missing.
Edit:
Also, you could try to set the following parameters with gn args:
visual_studio_path = "..."
visual_studio_version = "2017"
wdk_path = "..."
windows_sdk_path = "C:\Program Files (x86)\Windows Kits\10"
To set those parameters, do:
gn args out.gn/x64.release
This will open a text editor where you can write the extra parameters you are interested in.
To see the full list of parameters you can specify:
gn args --list out.gn/x64.release
I was following this guide https://medium.com/dailyjs/how-to-build-v8-on-windows-and-not-go-mad-6347c69aacd4 and also ran into the error
LINK1181: cannot open input file 'advapi32.lib'
I'm pretty sure it was because I had the wrong versions of the Windows 10 SDK. Similar to you I had versions:
Windows Kits/10/Lib/10.0.10240.0
Windows Kits/10/Lib/10.0.16299.0
But according to https://chromium.googlesource.com/chromium/src/+/master/docs/windows_build_instructions.md#Setting-up-Windows (Which I think is relevant) you need version 10.0.15063.0
After installing version 10.0.15063.0 (with the visual studio installer) to
Windows Kits/10/Lib/10.0.15063.0
I was able to continue with the build.
I'm trying to learn C++ programming with wxWidgets and CodeBlocks (with MinGW) and earlier today I succeeded in installing the software (after some trouble) to my Windows 7 computer with the guidance given to me in this post:
wxWidget 2.8.12 not working in Codeblocks
Later on the same day, I did the exact same steps on another Windows 7 machine and after creating a wxWidgets project and trying to compile and run it I got the following errors:
\wxWidgets-2.9.4\include: No such file or directory
\wxWidgets-2.9.4\lib\gcc_lib\mswu: No such file or directory
I have checked and these folders really do exist on those locations...so what seems to be the problem here again?...on the earlier post user asanth kumar guided me that if the steps given in the guide don't get the job done, then I'm missing an important compiler search path in my build options.
Ok, so what do I do? Where do I enter the search path? What is the search path, etc. I'm very new with wxWidgets and CodeBlocks so I don't know very much terminology. If anyone should know what to do, could you please give me like step by step instruction what to do e.g. like Click Project --> Build options --> ... and so on
I have used the latest CodeBlocks (12.11) and wxWidgets (2.9.4) installers
Thank you for any help :)
UPDATE:
here is the build log: (I'm using CodeBlocks 12.11 and wxWidgets 2.9.4)

Here is also a picture where you can see Build options, global variables and build log on my CodeBlocks:
NOTICE FUTURE READERS: Install wxWidgets to a directory without whitespace in the path name. The problems in this post was because the directory path had spaces in it
When you create a wxWidgets project.Have you did this?
File->New->Project->wxWidgets Project->Click Go->Click on Next->click on the suitable wxWidgets 2...version->click Next->Give project Name->Click on Next->Click on Next
After that the Following below Screen comes in the Wizard. Give the wxWidgets Location(Path where You installed the wxWidgets 2.9.4)
After that click on Finish.
For Environment Variable Path Setting
Follow the Below Steps:
Right click on MyComputer->Click on Advanced Systems settings->click on Environment Variables->click on New->Give variable name=Path and variable value="C:\Program Files (x86)\CodeBlocks\MinGW\bin" -> click ok
`
Try The Following Steps.It will work.
Updates about Build settings:
I am having the same problem as this and I somehow solved my problem.
I transfer my wxWidget folder to another location path that don't have white space name on it's path. For example above, "C:\Users\Jonne*Omat ohjelmat*\wxWidgets-2.9.4\include"
the path has white space between Omat ohjelmat. Try transfering it where the path contains no white spaces. For me, I put it on C:\wxWidgets-3.1.2
