Hi,
(post edited)
In a makefile can you change the directory to make files in subfolders?

A bat file is not a makefile. Here is a makefile tutorial

Sometimes editing a post in that nature is unnecessary and far less helpful to yourself. Edit changes, not the entire content!
Do you mean to run a makefile from within a makefile? What are you trying to achieve first?

GNU Make can call "make -C some_dir" to enter some_dir and make there. Or, if you simply want it to look for source-files in multiple folders, try the VPATH-directive.
http://www.gnu.org/software/make/manual/make.html is your friend.

Hi and thanks for your replies, sorry I wasnt very clear in what I am trying to acheive. I hope this will make more sense.
I have a subfolder, called GFX in my project folder. Inside GFX I have a simple BMP file that when I update it I would like my makefile to process it.
To manually update the BMP file I would normally use a command line command GFX2GBA.EXE with flags
Below is some of my makefile contents:
| Code: |
gfx/IMAGE.raw.c : gfx/IMAGE.bmp
gfx/gfx2gba -fsrc -x -t8 gfx/IMAGE.BMP
|
This works but the problem I have is the output from "GFX2GBA" is put in to my project folder, and I would like it to be in my GFX folder with the actual BMP file.
Also doing it this way requires me to add the path gfx/ to everything - even the command parameters.
I have read quite a few tutorials but I can't figure this out.
I appreciate the help I get from you guys. thank you.

Have you considered the -o option of gfx2gba to put the output in a given folder?

Make provides a shortcut $@ meaning the output file, a shortcut $^ meaning the input files, and a shortcut $< meaning the first input file. This should reduce the typing somewhat.

Cheers I will try that :)
I didnt even think to look at gfx2gba options! The shortcuts will come in very handy too.
#116664 - tepples - Sun Jan 28, 2007 1:02 am
There are also pattern rules using the % character, which make the shortcuts even more powerful:
| Code: |
%.raw.c : %.bmp
gfx/gfx2gba -fsrc -x -t8 $< -o$(<D) |
where $(<D) refers to the folder containing the .bmp file.
