DESCRIPTION:

Several packages from Qt 5.15 fail to compile on SDK with aarch64 with an error during compilation:

make[2]: Leaving directory '/home/rinigus/qt/qtdeclarative/upstream/src/qmltyperegistrar'
cd qml/ && ( test -e Makefile || /opt/qt5/bin/qmake -o Makefile /home/rinigus/qt/qtdeclarative/upstream/src/qml/qml.pro ) && make -f Makefile

At the same time, x86 version would work. Compilation would also work at OBS, see example package at Show home:rinigus:qt515:packaging / qtdeclarative - SailfishOS Open Build Service

PRECONDITIONS:

Get latest SFOS target and tooling. Add following repositories to compile:

Enabled repositories (global): 
 - adaptation-common ... https://releases.jolla.com/releases/4.5.0.18/jolla-hw/adaptation-common/aarch64/
 - apps              ... https://releases.jolla.com/jolla-apps/4.5.0.18/aarch64/
 - customer-jolla    ... https://releases.jolla.com/features/4.5.0.18/customers/jolla/aarch64/
 - hotfixes          ... https://releases.jolla.com/releases/4.5.0.18/hotfixes/aarch64/
 - jolla             ... https://releases.jolla.com/releases/4.5.0.18/jolla/aarch64/
 - sdk               ... https://releases.jolla.com/releases/4.5.0.18/sdk/aarch64/

Enabled repositories (user): 
 - qt515  ... https://repo.sailfishos.org/obs/home:/rinigus:/qt515:/packaging/sailfish_latest_aarch64/

STEPS TO REPRODUCE:

  1. Clone recursively GitHub - sailfishos-chum/qtdeclarative
  2. Checkout commit accee6958069df6c245b511d0d35275e79286d4d
  3. try to compile: mb2 -t devel-aarch64 build .

EXPECTED RESULT:

Corresponding section in successful log at OBS with the same target:

ACTUAL RESULT:

Compilation failed as shown in Description above.

MODIFICATIONS:

Described in “preconditions” above

ADDITIONAL INFORMATION:

Similar errors were observed with several other modules of Qt 5.15

This is an old and known bug, marking as tracked. It’s really not about “failing to run perl”, but about $directory not being set properly. In the old qt version, there was a workaround:

It looks like the problem is in /usr/lib/qt5/bin/syncqt.pl from qt5-tools [2]. Changing line 684 as follows fixes the problem for me:

-     $directory = abs_path($directory);
+     $directory = File::Spec->canonpath($directory);

As you are on a newer qt, the script might have changed a bit, so ymmv.

#3

@vige, thank you very much for a pointer! I will try it as well. However, how can it be that at OBS it runs without any issues? Any idea on what is OBS doing differently here?

#4

Sorry, no idea. That would require some investigation.

The way to fix this issue is to create a folder /srv/mer/targets inside the target for example by using sb2 -t devel-aarch64 -R mkdir -p /srv/mer/targets (replace target name “devel-aarch64” with correct one). The fix will be included in next release.
