When I am trying to launch flutter desktop application, this error occurred to me:

«CMake Error at CMakeLists.txt:2 (project):

Generator

could not find any instance of Visual Studio.

Building Windows application…

Exception: Unable to generate build files»

What I did…

1- Installed Visual Studio 2022 with (Desktop development with C++ and Universal Windows Platform development)

2- Run these commands:

flutter config —enable-windows-desktop

flutter create .

flutter run -d windows

Also I tried to use dev channel:

flutter channel dev

flutter upgrade

flutter config—enable-windows-uwp-desktop

And these what I have when I run flutter devices and flutter doctor

Я пытаюсь установить набор исполняемых файлов на компьютер под управлением Windows 10, и после загрузки их источников мне нужно скомпилировать их с помощью cmake. Я загрузил последнюю версию cmake и (после установки соответствующего рабочего каталога) пытался запустить следующие команды в командной строке Windows, чтобы установить исполняемые файлы:

mkdir build
cd build
cmake ../
make

Однако команды cmake последовательно приводят к следующей ошибке и не могут создать какой-либо файл make, который может использовать команда make:

-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:2 (project):
  The CMAKE_C_COMPILER:

    cl

  is not a full path and was not found in the PATH.

  To use the NMake generator with Visual C++, cmake must be run from a shell
  that can use the compiler cl from the command line.  This environment is
  unable to invoke the cl compiler.  To fix this problem, run cmake from the
  Visual Studio Command Prompt (vcvarsall.bat).

  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.

Я попробовал множество решений для работы cmake, и никто из них не работал. Я попытался добавить bin моей папки cmake в свою переменную окружения PATH, я попытался переустановить мою копию cmake и попытался использовать графический интерфейс CMake для создания файла make (Запуск CMake в Windows) и даже загружая Visual Studio (как установить переменную CMake CXX в Windows), но поскольку у меня недостаточно опыта использования графического интерфейса CMake или Visual Studio, или потому, что что-то происходит неправильно, ничего не работает вообще, cmake../ дает ту же самую ошибку.

Может ли кто-нибудь предложить мне несколько альтернативных решений о том, как заставить эту команду работать?

Hi all,

My name is Felipe. I am new to this forum

I am installing software on a cluster with CentOS Linux release 7.7.1908.

My software installation fails with ‘unknown language compiler’. Specifically:

— The C compiler identification is unknown
— The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:2 (project):
No CMAKE_C_COMPILER could be found.

Tell CMake where to find the compiler by setting either the environment variable «CC» or the CMake cache entry CMAKE_C_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH.

..and then the same for CXX

But, in any terminal command line, I can check this:

[Felipe@mu01]$ gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/libexec/gcc/x86_64-redhat-linux/4.8.5/lto-wrapper

and similarly for g++ -v

I also have cmake
[Felipe@mu01]$ cmake -version
cmake version 3.16.0-rc3
CMake suite maintained and supported by Kitware (kitware.com/cmake).
######################################################
And I also have mpich, which seems to handle mpicc, mpicxx, mpif90, mpif77.
For example:
mpicc -v
mpicc for MPICH version 3.1.4
##########################################################

I tried editing my ~/.bash_profile , but it did not help. Maybe I did not do it right.

I am rather lost on this.

1) Do my gcc, cmake and mpich suffice for all these purposes?
2) Where and how should I set those environment variables to be properly accepted by my software installer? /.bashrc ? .bash_profile? /etc/profile?

I appreciate your help,
Felipe
