Ubuntu under compilation Qt5

Compile Step reference: http://doc.qt.io/qt-5/linux.html

We use source code and compiled directory separation to compile, so as to avoid the compilation of the host system and the target system independence. Reference: Qt Configure Options | Qt 5.5

Compile options:

.. /.. /qt-everywhere-opensource-src-5.4.1/configure-prefix ~/qt5.4.1debug-debug-opensource-confirm-license-nomake Tests-egl-no-eglfs-no-linuxfb-opengl Es2

-EGL-NO-EGLFS-NO-LINUXFB and-opengl are added to match the target board Es2

The purpose of the-EGL is to detach the program from the X11 running EGL on the host, consistent with the target version. dependent libraries are libegl1-mesa-dev. After you install this library,-EGLFS-LINUXFB is also configured to compile by default, and the host is not available, so you need to remove the-NO-EGLFS-NO-LINUXFB on the host.

The-opengl es2 target runs on Es2, so the host also uses Es2. Dependent Library Libgles2-mesa-deb

In order to support the fonts under the System Library directory, the Fontconfig option is required, and if not, install the corresponding library file.

Common options are included:

./configure--help See what each option means

./CONFIGURE-V view the detailed procedures for the configuration to see the specific cause of the failure

The next step is to compile the target board's QT library. Target board for Raspberry Pi Pi2
