大家好、
我有一个非常令人沮丧的简单问题。 printf()不起作用！！！
我有两个项目、项目_A 和项目_B 我希望 PROJECT_A printf()起作用并将文本发送到控制台。
源文件相同、
//This does not work.
#include <stdio.h>
int main(void) {
printf("Hello");
fflush (stdout);
printf(" World!");
fflush (stdout);
return 0;
}
//This does work.
#include <stdio.h>
int main(void) {
printf("Hello");
fflush (stdout);
printf(" World!");
fflush (stdout);
return 0;
}
链接器命令文件是相同的、

我已经尝试使项目设置尽可能匹配。
这些项目随附在后。
谢谢！
解决了
