Xmake 版本

2.7.4

操作系统版本和架构

centos 7.8

描述问题

按照如下步骤能稳定复现c程序的注释报错的bug：
1 、执行xmake create hello
2 、cd hello
3、xmake
4、打开xmake.lua修改为

add_rules("mode.debug", "mode.release")
set_languages("c89", "c++11")

target("hello")
    set_kind("binary")
    add_files("src/*.cpp")
    add_files("src/*.c")

5、把main.cpp修改为main.c
6、随意复制一个c程序，只要是带注释即可

#include<unistd.h> //和fd有关[read() write() close()] lseek fork() execl() dup2() getpid()
#include<fcntl.h>//open()
#include<stdio.h>//perror()
#include<stdlib.h> //exit()
#include<dirent.h> //目录项操作：DIR opendir closedir readdir
#include<sys/wait.h> //wait()

#include<string.h>

int main(int argc,char *argv[])
{
    int ret;
    int fd[2];
    pid_t pid;
    char str[]="hello pipen";
    char buf[1024]={0};
    int status,w_pid;

    //创建管道
    ret=pipe(fd);
    if(-1 == ret){
        perror("pipe error");
    }

    pid=fork();
    if(pid>0){//父进程
        close(fd[0]);//关闭读端
        dup2(fd[1],STDOUT_FILENO);//屏幕输出重定向到管道 写入
        execlp("ls","ls",NULL);

        perror("exclp error");
        //因为使用exec函数族执行其他程序成功就不会回来了，所以下面就不用写了，只能指望隐式回收
        // close(fd[1]);
        // //阻塞等待子进程死亡防止僵尸进程
        // w_pid=wait(&status);
        // if(-1==w_pid){
        //     perror("wait error");
        //     exit(1);
        // }
    }else if(0==pid){//子进程
        close(fd[1]);//关闭写端
        dup2(fd[0],STDIN_FILENO);//从屏幕读取重定向到管道 读取
        execlp("wc","wc","-l",NULL);
        perror("exclp error");

        //执行成功不再执行以下的
        close(fd[0]);
    }

    return 0;
}

7、发现只要带注释的行都报错，有游离的»/»
8、发现是c标准的问题,改为c90后编译bug消失
9、但某些情况c89又能正常编译，忘了怎么触发的

期待的结果

报错如下

error: stray ‘342’ in program

error: stray ‘342’ in program

trying a code for a simple game i downloaded. when i run it i get lines and lines of this error:
error stray ‘200’ in program (with different numbers)
— i’m using code::blocks, in case that matters….

what does this mean??
here are the first lines of the code. the first error (one in subject) points to line 36

//Mine Field
#include <iostream> 
#include <exception> 
#include <string> 
#include <vector> 
#include <cstdlib> 
#include <ctime> 

using std::string;
using std::vector; 
using std::srand;
using std::time;


class StepOnMine {}; 
class FailedDisarm {}; 
class MineField 
{ 
	vector<bool> minefield; 

	//stores where the player has been 
	vector<bool> beenThere; 
	
	//current location of player
	int location; 

	int menu(string choices[], int numChoices)
	{
		using std::cout;
		using std::cin;

		int choice;
		do {
			for (int i = 0; i < numChoices; i++)
			{
				cout << i+1 << “) “ << choices[i] << “n”;
			}
			cin << choice;
		while (choice < 1 || choice > numChoices);
		return choice;
	}

thank you!!

Well, it is because there are “ and ” instead of » (note the slant!), and these characters are not valid.

………. it’s always the little things that matter

cin >> not <<

wow i guess there’s a lot wrong with this code.

I just got the same error doing something different now. In another example, i need to use this line:

#import «C:\Program Files\O2Gfxcore.dll»

does that mean the line is wrong or is the .dll library wrong?

Do you not notice the single backslash before fxcore.dll?

still getting the same error. I even moved the file to c: and used:

#import "C:\fxcore.dll"

and still same error

Could you copy and paste the error exactly?

Switch to forward slash / instead of double-backslashes. It works on Win, and means you don’t have to worry about double-slashes.

Which compiler (and preprocessor) are you using? Does it recognise #import? It’s not part of the C++ standard.

the code (i tried include in place of import, same problem):

#include <iostream>
#import "C:\fxcore.dll"

using namespace std;

int main()
{
   cout << "It works!!!n";
    return 0;
}

the error:

warning: #import is a deprecated GCC extension

Um…why are you using #import in that case?

Don’t use import. It seems that your preprocessor doesn’t recognise it.

Don’t #include a dll file. It’s meaningless. #include literally copies the entire file you want to include, and puts it into the place where you wrote #include .

Do not #include a dll file. I know I already said that, but I get the feeling saying it twice will help.

Why are you trying to #include a dll file? I think you must have misunderstood what a dll file is.
