Hi. can i use felo with cmake? If so, how can I do it?

Hi Didier,

you can use Felgo with cmake just like it applies to Qt. You can refer to the official Qt documentation to find more on this: https://doc.qt.io/qt-5/cmake-manual.html

Cheers,

Could you show us some(or a) working example(s)  with cmake please?Like how could we find the module of felgo?How could we link to them?Any felgo app build with cmake which could deploy to android or ios? Do you ever test?

 

Example:

find_package(Qt5 COMPONENTS REQUIRED Core Gui Widgets Multimedia Concurrent Network Sql Felgo????)

target_link_libraries(Qt5::Feglo?????)

 

Examples of Qt using cmake is not that many already compare with qmake, example of using felgo with cmake is even rare, this may seem easy for you because you are the developers, but for users, we have no idea what is the proper solution to link felgo with cmake, what should the name of Qt5::???? called? Just felgo?Or Felgo?Or FELGO?What about another plugin?How do we specify “assetsFolder.source” etc.

 

Thanks

By the way, Qt6 is going to adopt cmake instead of qmake, I think it is worth to invest on the documentation on cmake too.

Hi,

did you already check out this example? https://github.com/FelgoSDK/QtQuickFelgoLiveExample-CMake

Best,
Alex

Thanks for the example 🙂

Hello there,

When I try to compile the FelgoLiveExample on QtCreator (Felgo version), I’ve got an error on the line

find_package(Felgo REQUIRED)

CMake Error at CMakeLists.txt:30 (find_package):
  By not providing "FindFelgo.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Felgo", but
  CMake did not find one.

  Could not find a package configuration file provided by "Felgo" with any of
  the following names:

    FelgoConfig.cmake
    felgo-config.cmake

  Add the installation prefix of "Felgo" to CMAKE_PREFIX_PATH or set
  "Felgo_DIR" to a directory containing one of the above files.  If "Felgo"
  provides a separate development package or SDK, be sure it has been
  installed.

When I check on qt creator > help > about plugins, I have “Felgo Getting Started” and “Felgo Live” plugins well installed
If it can help I’m on Windows

So I found that my error was due to the CMAKE_PREFIX_PATH variable which was pointing to the Qt directory and not the Felgo Directory

set(CMAKE_PREFIX_PATH "C:/Felgo/Felgo/mingw_32")

This line allows me to build cmake.
Now I’m building my project and got the error

C:\Felgo\Felgo\mingw_32\include\Felgo\felgoliveclient.h:6: erreur : QApplication: No such file or directory

QApplication is on the Qt::Widgets library so, I include it as well :

find_package(Qt5 COMPONENTS Core Quick Widgets REQUIRED)

target_link_libraries(QtQuickFelgoLiveExample PRIVATE Qt5::Core Qt5::Quick Qt5::Widgets Felgo FelgoLive)

But when I compile I got this error which is a make error and is realy strange…

No rule to make target 'Felgo-NOTFOUND', needed by 'QtQuickFelgoLiveExample.exe'.  Stop.

I’m new to CMake and Felgo but this Behavior is strange isn’t it ?
In the same way, some of CMake commands do not work on Felgo Client but works on Qt Creator, like source_group(TREE … ) which has a weird behavior on Felgo Client…

What’s wrong ? I just download the Felgo client and The Github package given by Alex.
I tried on Qt Creator and the error was exactly the same
