In qtwebkit we are using -Wl,--no-keep-memory [1]. Maybe it will help you too?
(Honestly I don't know why it is a patch and not a line in debian/rules.)

You should not add any of these packages.

The compiler flags of the failing command -mfloat-abi=hard. It is a bug
in qtwebengine build system: on armel the float abi is soft, not hard.

Hi

Unfortunately the build logs does not show the compiler invocations, so it is 
a bit hard to guess what's going on.
But at least with webkit, we had to forcefully disable debug symbols to get 
stuff to build. dwarf2 is huge. and webengine is huge.
So start by checking that - and please make the build logs verbose.

/Sune

Re: QtWebEngine build fails

2016-12-25 Thread Sandro Knauß
Hey,

it looks like QtWebEngine[0] fails on armhf because there is too less ram/
space for building [1]:
/usr/bin/ld.gold: fatal error: libQt5WebEngineCore.so.5.7.1: Cannot allocate 
memory

Best Regards,

sandro
