New: QtWebengine doesn't build if the host hasn't a 32 bits C++ compiler working
https://bugs.busybox.net/show_bug.cgi?id=10531
Bug ID: 10531
Summary: QtWebengine doesn't build if the host hasn't a 32 bits
C++ compiler working
Product: buildroot
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: pinaraf at pinaraf.info
CC: buildroot at uclibc.org
Target Milestone: ---
When trying to build QtWebEngine for a raspberry pi 3 (ARM 32bits), a bunch of host tools are built using C++. Instead of being built directly for my amd64 arch, they are built for x86.
My debian sid installation was incomplete, I had gcc-multilib only and was missing at least libstdc++-7-dev:i386 and g++-multilib.
A warning from buildroot would be nice since this error occurs after a quite long build time.
As discussed on IRC?:
<gportay> kos_tom: Do you prefer to add a BR2_HOSTARCH_NEEDS_IA32_CXX_COMPILER; or BR2_HOSTARCH_NEEDS_IA32_COMPILER checks for both c and c++ multilib support? <kos_tom> gportay: that is a good question :-)
<kos_tom> I would say keep it simple, and just test for C++ support in BR2_HOSTARCH_NEEDS_IA32_COMPILER
<gportay> kos_tom: because we do not really want for force installation of c++ multilib when not needed
<gportay> okay
<kos_tom> but don't hesitate to raise this point in a note in your commit log, so that others can comment
Thanks to you guys for the support on IRC :)

--- Comment #2 from Yann E. MORIN <[email protected]> --- More globally: qt5webengine will build host tools that are the same bitness as the target, so it is not possible to build for a 64-bit target on a 32-bit host.
