Linking C++ code with 'gcc' (without g++)
提问by Rafael Almeida
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.
大家好：简短的问题：我现在只使用“gcc”（没有 g++）生成我的 C++ 可执行文件会很有用。这样做的原因是我必须将代码提交到自动提交服务器，该服务器无法识别“g++”（或“c++”，就此而言）命令。
In my experiments, while I'm compilinggcc 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.
在我的实验中，当我编译gcc 时效果很好。问题是，当我尝试链接生成的目标文件时，它会变得一团糟。现在，根据我从 gcc 手册页中的理解（我可能离题了，所以告诉我是不是），g++ 基本上是 gcc，但它链接了 C++ 库。
If this is true, how can I (if possible) explicitly link the C++ library withoutusing the g++ (or c++) command?
如果这是真的，我如何（如果可能）在不使用 g++（或 c++）命令的情况下显式链接 C++ 库？
EDIT:I'm adding the makefile to better illustrate the problem:
编辑：我正在添加 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

You can link the standard c++ library with the -lflag to gcc:
您可以将带有-l标志的标准 c++ 库链接到 gcc：
gcc cplusplus.o -lstdc++ -o myexe

If you run g++ with the "-v" option, it will show what command and options it uses. You should be able to deduce the correct gcc command line from there.
如果您使用“-v”选项运行 g++，它将显示它使用的命令和选项。您应该能够从那里推断出正确的 gcc 命令行。
