Package: qmake-qt5
Version: 5.4.2+dfsg-2
Severity: important

this is seen when building openjfx on arm64:
https://launchpadlibrarian.net/220388096/buildlog_ubuntu-wily-arm64.openjfx_8u60-b27-0ubuntu1_BUILDING.txt.gz
build.gradle chooses to set the linux-g++-m64 spec, and then fails on the unknown -m64 option. Trying to use the linux-g++ option fails, because the qplatformdefs.h of this spec is basically empty. This file is identical for the -m32 and -m64 specs, so why not include it there?

Come on Matthias, I'm trying to be helpful here and really though you might 
have mistakenly filed the bug in the wrong place. I even contacted Timo and 
Dmitry to take a look at the Ubuntu stuff (they are Ubuntu Qt maintainers) 
just in case this was the problem.

No need to, the patch you made is just the right thing to do: aarch64 uses 
linux-g++, not linux-g++-64.

Because it's not. Aarch64 should not be passed -m64 as the linux-g++-64 mkspec 
does. And it's not the only arch to do so, feel free to check qtbase-
opensource-src's debian/rules for more info.

So the bug is in openjfx, and as you already have a patch to fix it I won't 
reassign this bug but just close it.

regards, Lisandro.
