How do you create a static library instead of a .nds file? My guess is that you have to change your makefile and/or ds_rules and/or base_rules file, but I have no clue how.
I've tried many parameters, but I'm partially guessing them from pages like:
- http://forum.gbadev.org/viewtopic.php?t=1513&highlight=library+makefile
- http://lists.gnu.org/archive/html/help-gplusplus/2004-10/msg00015.html

This is the makefile that I use.

What I basically want is:
- build library libA
- build library libB, using libA
- build a program that uses libB

I've googled and searched the gcc webpage, but can't find a clear answer. Anyone?

here is the makefile that I use for my DS SDL library
look at the main targets section for how the lib is built

Code:

ifeq ($(strip $(DEVKITARM)),)
$(error "Please set DEVKITARM in your environment. export DEVKITARM=<path to>devkitARM)
endif

include $(DEVKITARM)/ds_rules

#---------------------------------------------------------------------------------
# TARGET is the name of the output

#---------------------------------------------------------------------------------------

Thanks! That was easy!

I just added:

Code:

-include $(DEVKITARM)/base_rules
$(OUTPUT).a : $(OFILES)

:D

I've got another problem:

I built library called COW.
The library that is called AlterNova uses COW and gets built too.

My program uses library AlterNova and thus also COW. So I link this program with both libraries. When I do that, I get many errors like:

Quote:

AlterNova/CTextureManager.h:145: undefined reference to `cow::CLog::~CLog()'

They're all undefined references to objects from AlterNova(and functions also) to COW.
Any suggestions why this is?

try adding the lib a second time to the link line

ie

-lA -lB -lA

or visa versa depending on the dependancies.

Oh my f... God :o
That solved it! It's official now: I hate GCC :P
Thank you v?ry much!

[edit]
-lB -lA does the trick too :o
(-lAlterNova -lCOW)
