[build2] Installation Error on Manjaro

[markus.pawellek at mailbox.org]

Hello,

I wanted to install build2 on several different platforms driven by 
Manjaro Gnome.
On the majority of these platforms, the installation process returned 
the following
error after compiling a few files.

  + build2/b-boot --version
  build2 99999.99999.99999
  libbutl 99999.99999.99999
  host x86_64-pc-linux-gnu

  + build2/b-boot config.cxx=g++ config.bin.lib=static build2/exe{b}
  warning: g++ looks like gcc but it is not
    info: use config.cxx to override
  error: unable to guess C++ compiler type of g++
    info: use config.cxx.id to specify explicitly

Is there a workaround to successfully finish the installation process?

Greetings
Markus
