Hi all,
As someone knows i'm tring to develop a VoIP application
for my ipaq 3850 (200 Mhz) using speex...
I guessed, for better perfomance, to build libspeex using GCC under linux or
cygwin with
--enable-fixed-point and --enable-arm-asm and use the compiled library under
Embedded VC++ 3.0.
I don't know if it's possible and only today i started to read
something about
cross-compiling so i wish to ask if someone did something similar to it
or can send me suggestion to achieve my aim...
I am doing exactly the same thing. ;)
I have all linking issues resolved now, except for the "end" symbol,
which is supposed
to be at the end of the .BSS section. I wonder how I can tell the Microsoft
LINK.exe
to add this symbol. After all there is no linker scripts like in Gnu-LD ;(
My cross-compiled code is entirely untested still. It may be that function-calls
result
in a crash due to incompatible stack cleanup. (__stdcall vs. __cdecl etc)
I had to compile parts of libgcc (lib1funcs.asm and libgcc2.c) as well as parts
of glibc
(the floating point emulation "soft-fp') to resolve a lot of unresolved
symbol errors during
linkage. As standard library for C I am using "newlib".

I might consider switching to uLibc later.
