When using makefile to run the executable file generated in the current directory: m akefile:3 : recipe for target 'test' failed similar error. It is very likely that the value returned to make after the program running is not 0.
1.test.c
#include<stdio.h>
int main(){
printf("----------------\n");
return 2;
}
2. Makefile
target: requests
[tab] command
must be preceded by the tab key
test : test.c
clang test.c -o test
./test
Command line running: make test
3. Modify the return value of the end of test. C program
#include<stdio.h>
int main(){
printf("----------------\n");
return 0;
}
4. Command line operation: make test
business as usual!
