Tdesktop: [Question] Compilation error

[dehqan]

Hi,
I've done all of the instructions which was written, but after opening Telegram.sln and building it, these errors occurred.
What else I need to do in order to solve these errors and run telegram.exe?

Specifications
Visual Studio Enterprise 16.7.0
Windows 10 SDK 10.0.18362.0
tdesktop git branch: dev

Stop closing and creating new issues, use only one issue until you compile :see_no_evil:

I guess you didn't fix https://github.com/telegramdesktop/tdesktop/issues/8413 in the fact, force argument can't fix what you described on that issue. And that error can appear only if -D DESKTOP_APP_USE_PACKAGED=OFF is not set.

Stop closing and creating new issues, use only one issue until you compile 🙈

I guess you didn't fix #8413 in the fact, force argument can't fix what you described on that issue. And that error can appear only if -D DESKTOP_APP_USE_PACKAGED=OFF is not set.

sorry 😥, I thought they are different issues and have to separate them.
after all, I did a clean install and everything has been resolved.
except this error from vs build output console:

cl : command line error D8040: error creating or communicating with child process

beside that building is failed, I wonder what's D:\agent\_work\9\s\src\vctools\Compiler\Utc\src\p2\main.c
cause I have only one drive and that is C 😕

so how can I fix this problem?

This is a MSVC bug, you need Visual Studio 16.5 (16.6 and 16.7 both are buggy and won't compile tdesktop) :(

MSVC source file where the bug is placed :D

@dehqan Replace

auto endpoint = blabla{

With

blabla endpoint = {

I have the same issue as described by dehqan in the first message: I can't compile on Windows because of _VARIANT_BOOL. It is defined in the system header like this:

/* 0 == FALSE, -1 == TRUE */
typedef short VARIANT_BOOL;

#if !__STDC__ && (_MSC_VER <= 1000)
/* For backward compatibility */
typedef VARIANT_BOOL _VARIANT_BOOL;

#else
/* ANSI C/C++ reserve bool as keyword */
#define _VARIANT_BOOL    /##/
#endif

When I compile Telegram I got these errors:

Just like he - with clean install

[GeorgeGribkov]

I don't quite understand. What do you mean by "clean install"?

[ilya-fedin]

What do you mean by "clean install"?

Well, this was said by @dehqan originally, but I guess he meant removing all the files created when building tdesktop and following the instruction from the beggining.

[GeorgeGribkov]

Thanks!

[dehqan]

@dehqan Replace

auto endpoint = blabla{

With

blabla endpoint = {

Hi, Thanks for your reply,
cause i'm new to this project, could you please say where should i apply these changes?

[dehqan]

This is a MSVC bug, you need Visual Studio 16.5 (16.6 and 16.7 both are buggy and won't compile tdesktop) :(

Thanks for your reply!
I'll try that

Where you got the error:

Well, clean install hasn't help me: I still got that error. How can I fix this?

[john-preston]

@GeorgeGribkov Please update Visual Studio to 16.7.1

[GeorgeGribkov]

@GeorgeGribkov Please update Visual Studio to 16.7.1

Have just updated, and this doesn't work :(

[john-preston]

@GeorgeGribkov I'm working on tdesktop using 16.7.1, so generally it should be fine on the current dev branch code.

[dehqan]

I've updated to 16.7.1 and moved to master branch. everything works fine!

I had those issues as well, but the key is to do all of the steps carefully, specially the last and configuration step. keep an eye on your output and be sure to have no errors.
