emulationstation on OSMC 2018.04-1 fails because of c++ compiler

[a2ron]

OS: OSMC 2018.4-1

Kodi fails when runs Retrosmc Launcher, something like:

opencv:exec permission denied

I got following text extract from install script output:

Could not successfully build emulationstation - EmulationStation - Frontend used by RetroPie for launching emulators (/home/osmc/RetroPie-Setup/tmp/build/emulationstation/emulationstation not found).

Any idea about it? I'm so lost...

Looks like dependencies were not downloaded correctly. Do you have a good internet connection? I'd suggest to try the installation again.

Yes, I did it multiple times... It seems something related to the GCC COMPILER version. I had version 4.6 but emulationstation is compiled with 4.7 I guess. I did remove gcc and install gcc-4.7 with aptitude and now it is compiling... We will see in a few minutes.

sudo aptitude install gcc-4.7
