Error compiling K on Ubuntu 16.04

[b-seite]

Hi Carles,

since several Days (around a week or so) i am struggling around with compiling K.
The compiling stops with an Error collect2: error: ld returned 1 exit status but i can not extract the error. Maybe you have an idea?

Here is some more output right before the error:

It happens with the latest commits. I rebuilded the dependencies and the machine is up-to-date.

thank a lot in advance

I edited line 5 & 6 in the makefile to where it was ten days ago:
CXX = $(CHOST)-g++-6 CC = $(CHOST)-gcc-6
and the Problem was gone. So it seems to be an issue with the GCC version on Ubuntu?

yea we found this the other day on IRC too. the problem is that for my cross compilation build process i need the -6 out, as you say is mandatory to use g++ v6, but is a mess the -6 for compile for darwin from debian

what i do is to relink correctly /usr/bin/g++ to /usr/bin/g++-6 instead of whatever is by default on a given distro/buildchain

i will try to add this note about the "check links before compile" (cos i really dont want to put back the -6 :P)

[ctubio]

or we could check g++ version before make dist and make to show a nice readable user error on mismatch xD

many thanks for insist on this'¡
