cannot execute ‘cc1plus’: execvp: No such file or directory

I can't build a cpp file by using the powerpc64-linux-gnu-gcc-10 build command. I get the error powerpc64-linux-gnu-gcc-10: fatal error: cannot execute ‘cc1plus’: execvp: No such file or directory.

$ sudo apt-get install gcc-10-powerpc64-linux-gnu build-essential

$ whereis cc1plus
cc1plus:

I tried to install gcc and g++ packages, with no success.

UPDATE :

Ok I managed to build by using g++ instead of gcc :

$ sudo apt install g++-10-powerpc64-linux-gnu qemu-user

$ powerpc64-linux-gnu-g++-10 -o test.bin test.cpp

$ export QEMU_LD_PREFIX=/usr/powerpc64-linux-gnu/

$ qemu-ppc64 ./test.bin

(Sorry for not commenting first, not enough rep)

The Ubuntu package search indicates that cc1plus for gcc10 on powerpc64 is provided by the package g++-10-powerpc64-linux-gnu.

Check if the package is installed and try again:
sudo apt install g++-10-powerpc64-linux-gnu
