" recipe for target 'main.o' failed"
please help me how to debug it..

Where did you get the makefile?

[Abhik]

its installed in that DEV C++ software

[weaknessforcats]

The makefile is generated based on your project code. Without seeing your code for main(), I can't say for sure but you may not have compiled correctly.

Generating an object file ( a .o) can fail if your code has errors.

Are there any other errors before this one?

[Abhik]

this is the makefile that is generated...

this line showing error...

All this tells me is that the error is in main.c. Generated makefiles like this one don't fail because of errors in the makefile.

That is, errors in your code are causing this. This also means that you are getting more errors than the one you reported.

What does your main.c look like?

[Abhik]

this is my main function

#include <stdio.h>
#include <stdlib.h>

/* run this program using the console pauser or add your own getch, system("pause") or input loop */

int main(int argc, char *argv[])
{
return 0;
}

There are no errors in the code you posted. Is this the exact code you were compiling?

[Abhik]

yeah...while compiling the same program its showing that error...

Maybe gcc.exe is not accessible with your current PATH.
try typing the offending command at the command prompt:
gcc.exe -c main.c -o main.o
This can't succeed because it doesn't include the CFLAGS, but the nature of the failure will tell you if gcc is running. That command line should succeed if you temporarily comment out the #includes in main.c.

Another possibility is that the long list of include paths makes the expanded command line too long for your shell.
