WinAVR no rule for main.elf

Question

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

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

Try to run make in a command prompt window. If the output is the same, it's a problem with MFile and/or make. If it works, it's a problem with Programmer's Notepad. Why did you tag your question `cmake`? — the busybee, Oct 10 '19 at 06:15
Open the Command Prompt, for example by entering "cmd" in the search box of the start menu. A windows with black background opens and shows white text that "prompts" you for commands. You change directories by "cd" and the target, please see a decent documentation of tutorial. Most (Windows) commands know the option "/?" to print some help. For example enter `cd /?`. Change into the directory of your project where the "Makefile" is. There call "make". NOTE: It's really worth to learn to use the Command Prompt, commonly known as "console" and "shell." Each developer should be able to use it. — the busybee, Oct 10 '19 at 18:25
I tried in [console](https://i.stack.imgur.com/mKLsX.png) and in [ide](https://i.stack.imgur.com/KCVU1.png) agian, but no hope.. — Maifee Ul Asad, Oct 11 '19 at 03:16
No, another new message I changed the code too.. Simplest code for mc, blinking led — Maifee Ul Asad, Oct 11 '19 at 05:40
So, please, [edit] your question and show us the new code and the new error messages! We don't have a glass sphere to look into. ;-) — the busybee, Oct 11 '19 at 05:47
@thebusybee can you take a look now, make file is as it was, main.c is here, and new error message pasted — Maifee Ul Asad, Oct 11 '19 at 08:05
The makefile in line 607 and 611 calls `sh` and does not work on your system. The two offending lines expand to `sh mkdir . 2>/dev/null` and `sh mkdir .dep 2>/dev/null`, resp. Your system (Windows?) can't run this, perhaps due to a missing or wrong `sh.exe`. 1) Can you run `sh`? If so, quit it by `exit` or Ctrl-D. 2) If you can, what is the output of `where sh`? Search for more `sh.exe`, there might be some more. — the busybee, Oct 11 '19 at 08:21
And where is `sh`? Is it part of WinAVR's binaries? Are there more of it? Please, don't let me pull each detail one by one... — the busybee, Oct 11 '19 at 11:38
Now try this, just to see if the rest of the makefile will work: 1) Put a comment sign '#' in front of line 607 of the makefile to disable the call of `sh`. 2) Edit line 611 of the makefile deleting the call of `sh` so that it reads `-include $(wildcard .dep/*)`. 3) Create a directory `.dep` (note the dot!) if it doesn't exist. And 4) run make again. What's the result? BTW, You can [edit] your question to document all the steps we made so that others can jump in. — the busybee, Oct 11 '19 at 12:17
I did the same thing on window 7 and everything worked out smooth for me — Maifee Ul Asad, Oct 26 '19 at 18:15
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.. i'm somewhat satisfied with it — Maifee Ul Asad, Oct 26 '19 at 18:17
That's OK if you know what you're doing. Make is just a tool to simplify the work in projects. It's your freedom to **not** use it. ;-) — the busybee, Oct 26 '19 at 20:24
