Got “-std=c++11: command not found” error when trying to compile a object file using g++

Question

As in the title, when I try to compile an object file using g++ by running this shell script:

#!/bin/bash
name=textsweeper
srcdir=src
buildir=build
cc=g++
cppflags=-Wall -std=c++11 -ggdb -O
libs=
rm -f $buildir/$name $buildir/main.o
$cc $cppflags $srcdir/main.cpp -c -o $buildir/main.o
$cc $buildir/main.o $libs -o $buildir/$name

I get the following error:

$ bash compile
compile: line 6: -std=c++11: command not found

And other errors about things being only available only with stdc++11. I've tried yahooing the error, but I've only got answers to about errors about actual command not arguments.

Variable assignment is space sensitive. Change:

cppflags=-Wall -std=c++11 -ggdb -O

to

cppflags="-Wall -std=c++11 -ggdb -O"

Otherwise, you're trying to run the command -std=c++11 -ggdb -O with the environment including a setting of cppflags=-Wall . bash allows temporary environment settings to be done this way, which is why its important to quote any variable assignments that contain spaces.
