Native Build Raspberry
-
Hello,
I would like to build Qt on a raspberry and i try to follow this tuto :
https://wiki.qt.io/Native_Build_of_Qt5_on_a_Raspberry_Piit's writen we have to tweak /opt/qt5/qtbase/configure script by replacing or adding code into it.
My problem is i can't find where to paste the code in the file. do someone has already done it?
i am not sure i am openning the right file but even using grep into the repository, i can't find the line.Thanks you,

Hm, another wiki which recommends cloning Qt instead of using a tarball. Weird. If you want to save space, I recommend taking a look at https://download.qt.io/official_releases/qt/5.10/5.10.1/single/
Regarding the native compilation - there is a much simpler way, although it comes with some caveats. Plus, it's been a good several months since I last attempted it so YMMW.
- get Qt source code
- do not modify any config script nor mkspecs
- just run configure natively like on a desktop Linux (without -device, -device-option, CROSS_COMPILE flags etc.)
- make
This way definitely works for qtbase (so QtCore, QtNetwork, QtGui and the like). With other modules you may be less lucky. Also, I think it only worked for XCB. For EGLFS plugin, some extra tweaking would be necessary (mkspecs - to enable the VC4 OpenGL driver and EGLFS config).

Ah, then you need OpenGL indeed. QML performance on xcb plugin is abysmal, EGLFS is the only way to go there.

@ClementD You need to install dev packages for OpenGL. See here: http://doc.qt.io/qt-5/linux.html
sudo apt-get install build-essential libgl1-mesa-dev
