Yeah, really annoying when using makefiles in MSDOS prompt. g++ -g -c -o main.o main.cpp g++.exe: no input files MAKE: *** [main.o] Error 1 it works if I write g++ -g -c -o main.o main.cpp but not with makefile. This is stupid because I cannot use VIDE or DevCpp, only with MSYS sh shell makefiles work. Win98. Thanks for help.

It sounds like a DOS-UNIX format problem. Make sure to save the file in Unix mode (LF only). There''s probably a trailing CR character after the .cpp so it''s trying to open the file "main.cpp\r" which isn''t a valid file.

Didn''t help. I changed VIDE to use LF only (and checked in binary editor and there was only 0x0A at the end of each line).

Damnit, I just need tool to use gdb (not at command line).

What does your makefile look like?

It should be ok. It is generated with VIDE (same problem with DevCpp and my custom made makefile).

But here it is:

$(oDir)/main.o: main.cpp
	$(CC) $(C_FLAGS) $(incDirs) -c -o $@ $<

This is weird. I found many similar problems with Google, but no-one has a solution. And it is more weird that I remember that long time ago I used DevCpp and it was ok.

Very strange.

I typically use Cygwin for console development, so I haven''t had any problems with make.

Do you have to use the MSDOS prompt, or could you get a copy of bash from the DJGPP package?
