c++ mode chooses "cc" as linker and cause error

c++ mode chooses "cc" as linker and cause error

Dear there,

on my machine, "M-x compile" choose "make -k", which in turn choose "g++"
and "cc" for my cpp file. How can I ask emacs to pick "g++" as linker as
well. Note that for some files, I just don't want to write a makefile for
it, and expect default make -k to work properly. thanks.

Make works only with a make-file. If you don't have and don't want to  
use a makefile, then simply substitute the text "make -k" with "g+ 
+ ...".

Run 'make -k' from the command-line instead of from within emacs.

If it fails the same way, the problem is in your makefile and not
emacs' fault at all.

When g++ sees the .cpp suffix it uses g++.

Emacs doesn't pick the linker.
You tell emacs to compile with make,
make picks the right compiler/linker from the suffix.

You can cusomize the emacs variable 'compile-command'
to default to something other than "make -k".
