将C ++代码与'gcc'链接(不含g ++) [英] Linking C++ code with 'gcc' (without g++)
问题描述
在我的实验中,当我编译时,gcc运行良好。问题是,当我尝试链接生成的对象文件时,它会变得混乱。现在,基于我从gcc手册页了解的内容(我可能会离开,所以告诉我,如果我是),g ++基本上是gcc,但是它链接了C ++库。
$ b $如果这是真的,我如何(如果可能的话)使用g ++(或c ++)命令显式地链接C ++库而不使用?
编辑:我添加了makefile以更好地说明问题:
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 / *
标准c ++库,其中 -l </ code>标志为gcc:
gcc cplusplus .o -lstdc ++ -o myexe
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/*
You can link the standard c++ library with the -l
flag to gcc:
gcc cplusplus.o -lstdc++ -o myexe
