使用控制台输入进行Eclipse调试 [英] Eclipse debugging with input from console
问题描述
我正在尝试调试使用Eclipse用C ++编写的程序。
该程序包括从用户那里获取输入,但是当我将输入输入到控制台时,它将永远不会继续运行代码(它将继续要求输入)。
如果不解决此问题,我将无法调试,希望对您有所帮助。
谢谢。
I'm trying to debug a program I wrote in C++ using Eclipse. The program includes getting input from the user but when I enter the input to the console it won't ever continue running the code (it'll keep asking for input). I can't debug without fixing this and would appreciate some help. Thank you.
代码被困在while循环fgets中:
The code gets stuck on the while loop fgets:
int main(int argc, const char**argv) {
FILE* inputFile = NULL;
setlocale(LC_ALL, "");
if(argc == 2){
inputFile = fopen(argv[1], "r");
if (inputFile == NULL){
printf("Problem opening file %s, make sure correct path name is given.\n", argv[1]);
return 0;
}
}
else {
inputFile = stdin;
}
char buffer[MAX_STRING_INPUT_SIZE];
// Reading commands
while ( fgets(buffer, MAX_STRING_INPUT_SIZE, inputFile) != NULL ) {
fflush(stdout);
if ( parser(buffer) == error ){
printf("ERROR\n");
break;
}
};
fclose(inputFile);
return 0;
}
推荐答案
问题来自Eclipse缓冲控制台输入。
修复它的一种方法是强制Eclipse使用Windows / DOS本机控制台进行调试。
The issue comes from Eclipse buffering the console inputs. One way to fix it is to force Eclipse to debug using a Windows/DOS native console.
详细说明了该过程,但要简短地说:
The procedure is described in details here, but in brief :
- 从Eclipse菜单文件>新建> C ++项目
- 创建您的Hello World C ++命令行项目,在您的项目文件夹中,创建一个。 gdbinit文本文件。它将包含您的gdb调试器配置
- 编辑 .gdbinit,并添加以下行(不带引号): set new-console on
- 在Eclipse中,转到菜单运行>调试配置,然后在左窗格中选择您的应用程序名称
- 在调试器标签中,立即确保 GDB命令文件指向您的 .gdbinit»文件。否则,输入 .gdbinit配置文件的路径
- 单击应用和调试。你完成了 !应该启动本机DOS命令行。
- Create your Hello World C++ command line project, from the Eclipse menu File > New > C++ Project
- In your project folder, create a ".gdbinit" text file. It will contain your gdb debugger configuration
- Edit ".gdbinit", and add the following line (without quotes) : "set new-console on"
- In Eclipse, go to menu Run > "Debug Configurations", and select your application name in the left pane
- In the "debugger" tab, ensure the "GDB command file" now points to your « .gdbinit » file. Else, input the path to your ".gdbinit" configuration file
- Click « Apply » and « Debug ». You’re done ! A native DOS command line should be launched.
