C++ – Linking C++ code with ‘gcc’ (without g++)

c++gcclinker

Hi all: quick question: I'm in a situation where it would be useful to generate my C++ executable using only 'gcc' (without g++). Reason for this is that I have to submit the code to an automatic submission server which doesn't recognize the 'g++' (or 'c++', for that matter) command.

In my experiments, while I'm compiling gcc works well. Problem is, when I try to link the generated object files it gets messed up. Now, based on what I understood from the gcc man page (I may be way off, so tell me if I am), g++ is basically gcc, but it links the C++ library.

If this is true, how can I (if possible) explicitly link the C++ library without using the g++ (or c++) command?

EDIT: I'm adding the makefile to better illustrate the problem:

COMPILER = gcc
CFLAGS = -Wall -g -x c++

# MODULE COMPILATION
model: modules/model.h modules/sources/model.cpp
    $(COMPILER) $(CFLAGS) -c modules/sources/model.cpp -o obj/model.o

algorithms: modules/algorithms.h modules/sources/algorithms.cpp
    $(COMPILER) $(CFLAGS) -c modules/sources/algorithms.cpp -o obj/algorithms.o

io: modules/io.h modules/sources/io.cpp
    $(COMPILER) $(CFLAGS) -c modules/sources/io.cpp -o obj/io.o

stopwatch: modules/stopwatch.h modules/sources/stopwatch.cpp
    $(COMPILER) $(CFLAGS) -c modules/sources/stopwatch.cpp -o obj/stopwatch.o

# EXECUTABLE GENERATION
exe: model algorithms io stopwatch
    $(COMPILER) $(CFLAGS) main.cpp obj/model.o obj/algorithms.o obj/io.o obj/stopwatch.o -o bin/process

# DEFAULT TEST CASE
run: exe
    ./bin/process -i data/nasa_small.log -a data/nasa_small.access -s data/nasa_small.stack

# CLEANING ROUTINE
clean:
    rm -f obj/*

Best Solution

You can link the standard c++ library with the -l flag to gcc:

gcc cplusplus.o -lstdc++ -o myexe
