gp32- thread and debug support

[kidchaos2k8]

Hi all!

Hope that anybody still uses these forums regarding gp32 development... I usually posted doubts in the mailing list but i wasnt aware of the forums...

I have been trying to make some developments for the gp32 during the pasts years and i am very grateful to the tools that dkpro provides... Recently i have succeded on building the latest toolchain on my Vista, however i applied some modifications:
- gcc-4.3.2 (no diffs applied)
- patched newlib adding a subset of pthreads ( appliying the diffs from the gp32 FreeSCI project - http://www.retrovg.com/gp32/)
- modified libstdc++-v3 to support the pthread subset (hardly patched )...

If i understood correctly there is no official support for a modified buildscript, but i would appreciatte if anybody could give me some suggestions about debugging:
I am trying to setup an environment with debug symbols for newlib (on my setup i am using an usb cable with a gdb stub to debug on hardware) but i found that all the libs in the dkarm environment are already stripped... Is there a way to build the enviroment with debug symbols active?
Also i would like to apply some modifications to gp32_crt0.s however i cannot inspect the code from insight of this file... I dont know exactly if i have to modify the .specs file or link a new crt0...

Any suggestion is welcome

Regards

The ARM toolset has now been updated to 4.3.2 anyway. The pthreads patches look a little dodgy to me being honest - there are patches to areas of newlib which aren't built or used by devkitARM. I'm a little concerned about the impact that kind of thing might cause on the other targets but do feel free to experiment for your own use.

comment out the bit in the script that strips the installed binaries, it's down at the bottom of build-devkit.sh

The gp32_crt0.s is distributed along with devkitARM for easy modification, it's in <path/to/devkitARM>/arm-eabi/lib - run make CRT=gba32 in that folder to rebuld the arm & thumb variants.
