Please help me compile QT5 on armv7

jshafer817

I am trying to natively compile QT5.4.2 on Arm.

I configure like this:
arch@honeybadger qt-everywhere-opensource-src-5.4.2]$ ./configure -confirm-license -opensource -prefix /usr -bindir /usr/lib/qt/bin -docdir /usr/share/doc/qt -headerdir /usr/include/qt -archdatadir /usr/lib/qt -datadir /usr/share/qt -sysconfdir /etc/xdg -examplesdir /usr/share/doc/qt/examples -plugin-sql-{psql,mysql,sqlite,odbc} -system-sqlite -openssl-linked -nomake examples -nomake tests -no-rpath -optimized-qmake -dbus-linked -system-harfbuzz -journald -libinput -no-use-gold-linker -no-reduce-relocations -no-sse2 -no-sse3 -no-ssse3 -no-sse4.1 -no-sse4.2 -no-avx -no-avx2 -opengl es2 -v -device-option DISTRO_OPTS=hard-float -skip qtwebengine -xplatform armv7l-unknown-linux-gnueabihf

and I end up with this: ( I have libinput, I think it has something to do with unknown architecture?)

Hi and welcome to devnet,

You should add which distribution you are using. Also, did you install all required dev packages ?

jshafer817

Thanks! Oh yeah that would be good to do. ArchLinuxArm is what I am using. I am using an HP Touchpad with libhybris which offers a hwcomposer plugin that works with android but only up to Qt 5.4. The problem is arch went to qt5.5 and I need a package to build something called hawaii. Old packages are not available, so I thought I would take a stab at compiling on the device.

I tried creating a qmake.conf directory in qtbase/mkspecs as you might be able to tell, no matter what I do, I get these errors.

I originally was trying to use makepkg but I get the same error.

Looks like currently you are missing the libinput package

jshafer817

That is what I thought, but it is installed. I am already using it to run qml-composer. I already have qt5 installed and working for weston, I just wanted to compile my own qt5.4.2...

I can compile qtwayland....

SGaist

Is the library in some place exotic on your system ?

jshafer817

Don't think so.

From the /usr folder I did the find command. I do have /lib but that is just a symbolic link to /usr/lib...

Can you try again without the -libinput option ? It should be auto-detected

I'm running Arch Linux as well, and have encountered this issue. The libsystemd-journal package has been merged into libsystemd, so you need to update Qt's configs accordingly. Drop the "-journal" suffix from "libsystemd-journald" (to just, "libsystemd") in the following files:

qtbase/config.tests/unix/journald/journald.pro
qtbase/src/corelib/global/global.pri

For example, here are the patches I applied to make get Qt to compile:
