[英]Compilation error with C++ (macOS)
嘗試在Mac(HighSierra:10.13.3版)中編譯此非常簡單的C ++程序時遇到錯誤。 在此Mac中使用的gcc版本是5.3.0。
這是C ++程序:
#include<iostream>
#include<cmath>
#include<fstream>
using namespace std;
int main()
{
cout<<sin(1);
}
在回答了先前的問題后,我使用xcode-select --install
安裝了命令行工具
在上述命令行安裝后,當我嘗試使用以下命令編譯該程序時
gcc filename.cpp -o filename.out
我收到以下錯誤:
/var/folders/mp/z7xpkw3538z71904cdqhztv00000gn/T//ccGJEHr7.s:24:11: warning: section "__textcoal_nt" is deprecated
.section __TEXT,__textcoal_nt,coalesced,pure_instructions
^ ~~~~~~~~~~~~~
/var/folders/mp/z7xpkw3538z71904cdqhztv00000gn/T//ccGJEHr7.s:24:11: note: change section name to "__text"
.section __TEXT,__textcoal_nt,coalesced,pure_instructions
^ ~~~~~~~~~~~~~

"std::cout", referenced from:

ld: symbol(s) not found for architecture x86_64

我怎么解決這個問題?
更新:
按照答案,現在我使用g++
,即
g++ filename.cpp -o filename.out
現在,我收到以下錯誤:
/var/folders/mp/z7xpkw3538z71904cdqhztv00000gn/T//ccJjEuJy.s:24:11: warning: section "__textcoal_nt" is deprecated

您正在使用gcc
編譯C源代碼。
就是這個問題,您應該改用g++
。
您可以嘗試使用g++
:
g++ filename.cpp -o filename.out
或Apple的clang++
:
clang++ filename.cpp -o filename.out
