I have a system in which I've been compiling programs with C++11 using automake and everything has been working.
However, when a different user take the same exact Makefile they get the aforementioned error.
Now, if they type in g++ --std=gnu++11 program.cpp then there are no complaints.
I've narrowed it down to a line that is causing the issue; however, I don't know how to fix it.
depbase=`echo no_endl.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
g++ -DHAVE_CONFIG_H -I. -I../.. -g --std=gnu++11 -g -O2 -MT no_endl.o -MD -MP -MF $depbase.Tpo -c -o no_endl.o no_endl.cpp &&\
mv -f $depbase.Tpo $depbase.Po
The problem is with depbase; however, I don't know what is going on with it or why it is there.
Below is the Automake file that I used to generate the Makefile:
bin_PROGRAMS = no_endl
AM_CXXFLAGS = -g --std=gnu++11
no_endl_SOURCES = no_endl.cpp
The only difference between my g++ and their g++ is I have an alias so g++ turns into g++ -g.

I solved the problem.
The problem was the $PATH variables for me and other users.
Now, other users have an alias for g++ to the newer version, but their $PATH omits the actual location.
Make works based on their $PATH variable, so to fix it, I just had to make sure their path had the same location as mine.
