Bitrise Qt5 build bot is failing

[brunoabinader]

This is probably caused by a wrong selection of the clang compiler version:

These errors started to pop up on Bitrise and also on my macOS:

In file included from ../../../include/mbgl/util/constants.hpp:3:
../../../include/mbgl/util/chrono.hpp:36:49: error: no template named 'enable_if_t' in namespace 'std'; did you mean 'enable_if'?
template <class Rep, class Period, class = std::enable_if_t<

../../../include/mbgl/util/optional.hpp:8:37: error: no type named 'optional' in namespace 'std::experimental'
using optional = std::experimental::optional<T>;
                 ~~~~~~~~~~~~~~~~~~~^

I'm going to disable Qt5 build bot until we find a fix for this.

Good evening,

I am getting this error when i try to run "make qt-lib".
I am using a MacOS Sierra; and Qt5.7 professional.
Do you have any workaround or solution to this?
thank you for your time.

[brunoabinader]

Once #6804 gets merged, we can re-enable the Bitrise Qt5 build bot.

@assanegu - yes, see 2d908c8.

[brunoabinader]

#6804 is now merged, I'm going to re-enable our Bitrise Qt5 bot 👍

[brunoabinader]

Bitrise Qt5 macOS build bot is now back on track 💯

[assanegu]

Thank you for the update.
The error is no longer happening; but I am still getting a different error that might not related to Mapbox.

FYI, here is the error:
/Users/systemName/Qt/5.7/ios/include/QtGui/qopengl.h:69:13: fatal error: 'OpenGLES/ES3/gl.h' file not found

[brunoabinader]

@assanegu this looks like something is missing on your environment setup - can you please provide details e.g. what operating system and build commands are you using to build?

Hi Bruno,
Thank you for your prompt reply. I am using a MacOS Sierra; and Qt5.7 professional.
As for the issue, I think I resolved the issue. The Qt5Core_DIR was pointing to iOS directory not to the clang_64 directory. meaning:
Qt5Core_DIR = /Users/myMac/Qt/5.7/ios/lib/cmake/Qt5Core
so I change it to:
Qt5Core_DIR =/Users/myMac/Qt/5.7/clang_64/lib/cmake/Qt5Core
and I was able to build it using "make qt-lib".
However, I did get the following warnings at the end of the build:

You need to provide an environment variable with your Mapbox access token as described in the README.

[assanegu]

You are right, I did not set the MAPBOX_ACCESS_TOKEN. now it's working. Thank you for your assistance.

[ghost]

Hello !

Can you explain me How you set access_token ?

Is it in .pro or directly in the QML ?

Thx

[brunoabinader]

Hi @ducmaxime, this repository only contains the C++ API (QMapboxGL), whereas the QML one is hosted in QtLocation repository.

You can find documentation about the Mapbox GL QtLocation plugin here: https://doc.qt.io/qt-5.10/location-plugin-mapboxgl.html#parameters

See below an example on how to provide access token information in QML:

    Map {
        plugin: Plugin {
            name: "mapboxgl"
            PluginParameter {
                name: "mapboxgl.access_token"
                value: <access token goes here>
            }
        }
    }
