Hi Eric,
Thanks for your help. I thought I would mention that I did a parallel install on Ubuntu 14.04 LTS, with g++ (Ubuntu 4.8.4-2ubuntu1~14.04) 4.8.4, with an OK build.
Back in my Ubuntu 15.10, installing g++-4.8 and doing
$ g++-4.8 --version
g++-4.8 (Ubuntu 4.8.5-1ubuntu1) 4.8.5
$ cmake -DCMAKE_CXX_COMPILER=g++-4.8 ..
still gives me the same build error.
I am out of my comfort zone, though, but could this be a linker issue? (I have no idea...)
$ ld --version
GNU ld (GNU Binutils for Ubuntu) 2.25.1
On my working 14.04
$ ld --version
GNU ld (GNU Binutils for Ubuntu) 2.24
Thanks, anyways.
Åsmund Hjulstad
