Ok set -v ^^

Well I get a libffi from gcc 3.4 tarball
I apply this patch :
libffi/configure.in~    2003-10-22 01:02:59.000000000 +0200
+++ libffi/configure.in         2003-11-11 12:33:40.000000000 +0100

 else
   libffi_basedir=
 fi
+libffi_basedir=
 AC_SUBST(libffi_basedir)
 AC_CONFIG_AUX_DIR(${libffi_basedir}..)

Then I mkdir libffi_bin at the top of gcc
cd libffi_bin ;
../libffi/configure 
--prefix=/home/commgw/renaud/gcc/gcc-3.4.0/libffi_bin --host=arm-linux 
--build=i386
make
export  LDFLAGS= -L/home/commgw/renaud/gcc/gcc-3.4.0/libffi_bin
export  LDFLAGS= -L/home/commgw/renaud/gcc/gcc-3.4.0/libffi_bin/include
export LD_LIBRARY_PATH=/home/commgw/renaud/gcc/gcc-3.4.0/libffi_bin 

Then I install sablevm-classpath :
./configure --prefix=/path/to/sablevm_bin --build=i386 --host=arm-linux 
--includedir=/home/commgw/renaud/montavista/pro/devkit/arm/xscale_le/target/usr/include 
--disable-gtk-peer

Ok for the moment,no problem.

Now I run sablevm like this :
./configure --prefix=/path/to/sablevm_bin --build=i386 --host=arm-linux 
--includedir=/home/commgw/renaud/montavista/pro/devkit/arm/xscale_le/target/usr/include 
-disable-gtk-peer --with-threading=direct

And then I have the foloing message  :
checking for ffi_prep_cif in -lffi... no
***ERROR: libffi is missing

humm I have set CC, AR, NM, ... before


Cheers,

Fabien
