Cmake build error could not load cache - Исправление ошибок и поиск оптимальных решений проблем

I’m using Cmake to try to build a project for Eclipse. When I try running Cmake, I get the following error:

Error: could not load cache
Error: Batch build stopped due to Eclipse CDT4 - Unix Makefiles error.
---- Time Elapsed: 3 secs ----
Error: could not load cache
Error: Batch build stopped due to Eclipse CDT4 - Unix Makefiles error.

I’m completely stumped on what might be causing this. I know that I’m running Cmake in the correct directory and the CMakeCache.txt file is present. Could someone point me in the right direction to solve this?

Remove the CMakeCache.txt and try again. You probably had a bad cmake setup.

I have faced the same problem and solved it using the terminal.

Delete the cached/configurations files as we will get them again.
To configure the project run cmake .
Build the project using cmake --build .

I ran into this recently using JetBrains CLion and the above instructions were helpful but not directly, I was able to reload the project using the «cog» drop down in the CMake tab:

If you are absolutely positive that you are running the build command from the binary directory, this error probably means that you have had an issue during the configuration/generation step that you should have ran before trying the build. You can try to configure again to check (cmake your-build-dir)

I would advise running the Gui and trying to load the cache to see if you get a more explicit error (although I doubt it).

Another possibility would be to try to create a new clean build directory and take it from there.

In your example Eclipse must run something like

cmake --build folder_name --target all

and I opt that the *folder_name* is bad in this case. You probably messed something up in Eclipse.

For me it helps to select CMake tab (next to Run, TODO) in CLion. Then click the Reload CMakeProject button.

I got this error on Windows WSL with ubuntu

~/tmp/cmake$ cmake --build ./build
Error: could not load cache

I was able to fix the above error by running the following cmds in order:

% cmake -S . -B ./build 
% cmake --build ./build

The above solution was derived from this post.

If you are using Visual Studio 2019, close Visual Studio, delete .vs and out folders then rebuild your project.

I removed the .cxx and other ide-generated files to the recycle.bin, except app.iml. Then I restarted Android Studio, and eventually it worked fine.

The solution that worked for me using VisualStudio 2017 was choosing:
CMake —> Cache —> Generate (from the top menu)

answered Sep 3, 2020 at 6:09

Apart from the already given answers, it might be due to the wrong commands or in wrong order.

To be precise, for me, it was due to

cmake -B build -G Ninja
cmake --build .

The «cmake —build .» command will throw the Could Not Load Cache error.

The problem is the build directory is given as ‘.’ which doesn’t have the cache or whatever files cmake generates, so correct command was ‘cmake —build build’… and fixed !

There maybe trillion other ways but my solution was this.

For eg, it happened with the repo -> https://github.com/adi-g15/worldlinesim, though may show the same for other repos too.

For Ubuntu users, provide the source code open-pose path in the CMake-GUI.

P.S I had this issue and my path was not set there.

Most probably the issue is you have not wrote the correct name of the Visual Studio version you have installed during the build file preparation:

cmake .. -G «Visual Studio 16 2019» (note if you have VS 2016 you should change in in there)

answered Jan 26, 2022 at 23:34

The most realistic answer and personal experienced answer is

If you are using Clion and building files with IDE
And getting the error Cmake Error: could not load cache
Because you have accidentally deleted the cache file (like me: permanently and cant get back) or there is other problems or other problems

Then do this:

Run -> Clean

Run -> Build

And your project will be working all fine

I guess you didn’t configure your project.

You first need to run cmake . at the project root to generate build files. You can also run it from an empty directory to separate source and build files.
Then you can use cmake --build ./ in the build dir.

Or, if you prefer code-only:

cd [root-directory-of-your-project]
cmake .
cmake --build ./

answered Aug 11, 2016 at 7:03

You could try:

Make sure you have enough space / correct permissions etc for the generated files to be created
Remove all generated files e.g. CmakeCache.txt and re-run cmake ..; check the output carefully for potential issues during this step, missing libraries etc.

cmake —build . is needed when building from your build directory

Those who encountered this issue while using Eclipse for ESP-IDF, the solution is go to: Window > Preferences > C/C++ > Build > Environment, and set IDF_CCACHE_ENABLE to 0.

I have fully build the system by the Installation document, but when I run the following command:
cmake —build build —target run_simulte-cars
I got a problem, the command line terminal output this:
could not load cache
I tried to solve this but failed，is there anyone meeting the same problem?
Thanks for your help

Hi Luge,

Are you sure that you ran cmake --build . before running cmake --build build --target run_simulte-cars ?

Unfortunately, I don’t have enough information to go on with what you have explained. Maybe if this doesn’t help tell me some more about your system i.e. what OS you have, OMNeT++ version and SUMO versions, they shouldn’t impact on cMake but it’s more to go on.

Here is my building environment list:
_

Ubuntu 18.04
SUMO 1.3.1
CMake 3.16.0
GNU GCC 7.4
OMNeT++ 5.5
Boost 1.65.1

_
I have successfully make all the necessary submodules by command make all and run command cmake —build before running cmake —build build —target run_simulte-cars .Then it throws the error, could not load cache, I tried to google it, but the methods did not work….
Thanks a lot for your reply.

Я использую Cmake, чтобы попытаться создать проект для Eclipse. Когда я пытаюсь запустить Cmake, я получаю следующую ошибку:

Error: could not load cache
Error: Batch build stopped due to Eclipse CDT4 - Unix Makefiles error.
---- Time Elapsed: 3 secs ----
Error: could not load cache
Error: Batch build stopped due to Eclipse CDT4 - Unix Makefiles error.

Я совершенно озадачен тем, что может быть причиной этого. Я знаю, что запускаю Cmake в правильном каталоге и файл CMakeCache.txt присутствует. Может ли кто-нибудь указать мне в правильном направлении, чтобы решить эту проблему?

Если вы используете CLion, вы можете использовать File—«Reload CMake Project».

Я сталкиваюсь с этой проблемой после использования git force pull, и Reload CMake Project решает ее.

Удалите файл CMakeCache.txt и повторите попытку. Вероятно, у вас была плохая настройка cmake.

ответ дан 15 окт ’14, 21:10

пробег cmake --configure . он должен генерировать необходимые файлы.

ответ дан 09 окт ’20, 12:10

Я столкнулся с той же проблемой и решил ее с помощью терминала.

Удалите кэшированные/конфигурационные файлы, так как мы получим их снова.
Чтобы настроить запуск проекта cmake .
Соберите проект, используя cmake --build .

Я столкнулся с этим недавно, используя JetBrains CLion, и приведенные выше инструкции были полезны, но не напрямую, я смог перезагрузить проект, используя раскрывающийся список «cog» в CMake Вкладка:

ответ дан 07 окт ’20, 13:10

Если вы абсолютно уверены, что запускаете команду сборки из двоичного каталога, эта ошибка, вероятно, означает, что у вас возникла проблема на этапе настройки/генерации, которую вы должны были выполнить перед попыткой сборки. Вы можете попробовать настроить еще раз, чтобы проверить (cmake your-build-dir)

Я бы посоветовал запустить графический интерфейс и попытаться загрузить кеш, чтобы увидеть, не появится ли более явная ошибка (хотя я в этом сомневаюсь).

Другая возможность — попытаться создать новый чистый каталог сборки и взять его оттуда.

В вашем примере Eclipse должен запускать что-то вроде

cmake --build folder_name --target all

и я полагаю, что *folder_name* в этом случае не подходит. Вы, вероятно, что-то напутали в Eclipse.

ответ дан 19 дек ’13, 14:12

Для меня это помогает выбрать вкладку CMake (рядом с Run, TODO) в CLion. Затем нажмите кнопку «Перезагрузить CMakeProject».

ответ дан 24 мая ’17, 15:05

Если вы используете Visual Studio 2019, закройте Visual Studio, удалите .vs и out папки, затем перестройте свой проект.

ответ дан 02 авг.

Я удалил .cxx и другие сгенерированные ide файлы в recycle.bin, кроме app.iml. Затем я перезапустил Android Studio, и в итоге все заработало.

Создан 12 ноя.

Решение, которое сработало для меня с использованием VisualStudio 2017, выбирало: CMake -> Cache -> Generate (из верхнего меню)

Создан 03 сен.

Помимо уже данных ответов, это может быть связано с неправильными командами или неправильным порядком.

Если быть точным, для меня это было связано с

cmake -B build -G Ninja
cmake --build .

«cmake —build». Команда выдаст ошибку «Не удалось загрузить кэш».

Проблема в том, что каталог сборки указан как ‘.’ у которого нет кеша или каких-либо файлов, которые cmake генерирует, поэтому правильной командой было «cmake —build build» … и исправлено!

Там может быть триллион других способов, но мое решение было таким.

Например, это произошло с репо -> https://github.com/adi-g15/worldlinesim, хотя может показать то же самое и для других репозиториев.

Для пользователей Ubuntu укажите путь к исходному коду с открытым исходным кодом в CMake-GUI.

PS У меня была эта проблема, и мой путь там не был указан.

ответ дан 13 авг.

Скорее всего, проблема в том, что вы не указали правильное имя версии Visual Studio, которую вы установили во время подготовки файла сборки:

cmake .. -G «Visual Studio 16 2019» (обратите внимание, если у вас VS 2016, вы должны изменить его там)

Создан 26 янв.

cmake -B ./build(целевой каталог)
cmake —сборка ./сборка(

ответ дан 24 авг.

Самый реалистичный ответ и личный опытный ответ:

Если вы используете Clion и создаете файлы с помощью IDE
И получаю ошибку Ошибка Cmake: не удалось загрузить кеш
Потому что вы случайно удалили файл кеша (как я: навсегда и не могу вернуться) или есть другие проблемы или другие проблемы

Затем сделайте следующее:

Выполнить -> Очистить

Выполнить -> Построить

И ваш проект будет работать нормально
