WinAVR no rule for main.elf

I am trying to generate .hex file to be burned on micro-controller.

I'm using WinAVR.

With MFile I generated makefile for my ATmega8. Here is the makefile

main.c

Now when I try to make all from Programmer's Notepad it gives me error saying :

> "make.exe" all
      0 [main] sh 4248 sync_with_child: child 7356(0x1D8) died before initialization with status code 0xC0000142
  15529 [main] sh 4248 sync_with_child: *** child state waiting for longjmp
/usr/bin/sh: fork: Resource temporarily unavailable
      0 [main] sh 10220 sync_with_child: child 3336(0x1E4) died before initialization with status code 0xC0000142

Compiling C: main.c
avr-gcc -c -mmcu=atmega8 -I. -gdwarf-2 -DF_CPU=8000000UL -Os -funsigned-char -funsigned-bitfields -fpack-struct -fshort-enums -Wall -Wstrict-prototypes -Wa,-adhlns=./main.lst  -std=gnu99 -MMD -MP -MF .dep/main.o.d main.c -o main.o

make.exe: *** [main.o] Error 1

What is the actual error here, what should I do ?

And in win10, I don't use makefile anymore, I directly use this two command from cmd

• avr-gcc -Wall -g -Os -mmcu=atmega8 -o main.bin main.c
• avr-objcopy -j .text -j .data -O ihex main.bin main.hex this works for me
