[question] how to get QSerialPort via Conan ? #15298

Closed lpmrfentazis closed 3 weeks ago

lpmrfentazis commented 10 months ago

What is your question?

Hi, this is my first time working with conan, I am trying to convert my colleague's project from qmake to cmake+conan, but ran into the fact that I can't seem to get QSerialPort, although the other parts of QT have been obtained.

Have you read the CONTRIBUTING guide?

Hi @lpmrfentazis

Thanks for your question.

Could you please share the full output of the conan install command and also the output of the cmake command? It can have useful information (please share it as text, better than image, so we can search, copy, etc). Thanks!

conan install . --output-folder=build --build=missing

memsharded commented 10 months ago

Ok, that is helpful. You can see that CMake is listing the available targets created by Conan: Conan: Component target declared 'Qt5::Core', and yours is not available there, so it is not found later.

The issue is that this component is not built by default, as it is not that commonly used. There is a recipe option in Qt5, you can check it for example listing existing binaries:

conan list "qt/[<6]:*" -r=conancenter
....
options                     
  commercial: False         
  ...    
  qtserialport: False

Or also in https://conan.io/center/recipes/qt?version=5.15.11 -> packages -> options

So trying:

conan install ... -o qt*:qtserialport=True --build=missing

Should opt-in into it (build it from source, as there is no pre-compiled binary for this configuration), the target should appear in the cmake output, and it should work.

lpmrfentazis commented 10 months ago

Ок, это полезно. Вы можете видеть, что CMake перечисляет доступные цели, созданные Conan: Conan: Component target declared 'Qt5::Core', а ваша там недоступна, поэтому она не будет найдена позже.

Проблема в том, что этот компонент не создан по умолчанию, поскольку он не так часто используется. В Qt5 есть опция рецепта, вы можете проверить это, например, со списком существующих двоичных файлов:

conan list "qt/[<6]:*" -r=conancenter
....
options                     
  commercial: False         
  ...    
  qtserialport: False

Или также в https://conan.io/center/recipes/qt?version=5.15.11 -> пакеты -> параметры

Итак, пытаюсь:

conan install ... -o qt*:qtserialport=True --build=missing

Следует зарегистрироваться в нем (собрать его из исходного кода, поскольку для этой конфигурации нет предварительно скомпилированного двоичного файла), цель должна появиться в выходных данных cmake, и она должна работать.

It worked, thank you!

lpmrfentazis commented 10 months ago

Or not... I'm not sure if it has to do with how the QSerialPort connected

Error messages are a bit difficult to understand if not in English, it seems Russian, and it seems that those are linking errors. They don't look directly related to the serial port, but something different.

It would be necessary to have something that we can reproduce, ideally a minimal main.cpp, a minimal CMakeLists.txt and the minimal conanfile to make it fail that way.

Hi @lpmrfentazis

Any update here? Did you manage to solve those link errors?
