theora dev - May 2007 - help with libtool!

Hi,

Now I am working on BCC Cross-compiler in order to get the binaries for
LEON3 (Google SoC 2007).

I changed these lines of Makefile ...

CC = gcc
CPP = gcc -E

... to these :

CC = sparc-elf-gcc -mv8 -msoft-float
CPP = sparc-elf-gcc -mv8 -msoft-float -E

The options means:
-mv8 : generate SPARC V8 instructions
-msoft-float : emulate floating-point

When I run "make", there is a error:
libtool: compile: unable to infer tagged configuration
libtool: compile: specify a tag with `--tag'

I think the libtool is linking some libraries of gcc instead of
sparc-elf-gcc.
How can I change this? is it in "configure" file?

Thanks,

Andr? Costa

PS: I wasn't getting to communicate with the LEON in FPGA by serial
interface, but I discovered the problem. The number code of my FPGA was
slightly different. The difference was just in mapping of pins. When I
changed of FPGA (to a cyclone), I got to run a hello word! For while I am
using the cyclone, but after I will need to map all the pins.

Woohoo! :)

I agree libtool is probably not picking up on the change. Try something 
like CC="sparc-elf-gcc -mv8 -msoft-float" ./configure
--target=sparc-elf
and see if that works better.

The GNU autotools generally have very poor support for cross-compilation 
though. It is probably worth just writing a custom makefile for it. Copy 
the list of relevent files from lib/(*/)Makefile.am and copy the 
relevent defines from config.h.in. You probably want:

#define THEORA_DISABLE_ENCODE 1

I don't think the library requires any of the others.
