Wow. Welcome, brother.
I am trying to port PIXIL..

The gcc compiler for DSLINUX has a modified code generator to compensate
for the lack of write strobes for the 32 MByte GBA ROM space as RAM.
It took me 3 months to do this. Are you _really_ want to port this mod

This is true. Qtopia is usable on devices with >= 200 MHz Clock.
And 32 MByte RAM for CODE and DATA is very limited...
It makes no sense to me to have a PDA environment where I am not able to
start any real applications because of memory requirements...
So I have decided to try PIXIL (www.pixil.org). It's not a good as
Qtopia, but it will run fine on the DS. And if the core of PIXIL is
running, we can add applets/programs/eye candy. I will be very glad if
we can program together.
I am able to compile and link PIXIL with DSLINUX, but the c++
environment of DSLINUX is broken. Without a fix, you will go nowhere
The problem is, that the C compiler include files are modified, and are
in the DSLINUX source directory.
For C++, the C++ header files are copied into the DSLINUX source tree,
but the gcc 4.0.2 c++ headers do not work with the (older?!?) C headers
in the DSLINUX source tree. We will have to compare the headers and fix
Compiling and linking with the unmodified C headers will lead to
We're back to the times when men were men
and wrote their own device drivers.
