Ok,

finally I've succeeded to build the shared libraries ( .so) with the 1.37 beta (it's more better than the previous 1.36 regarding jam problems) applying only a small patch into gcc.jam ( that still inserts --out-implib even that is .so and cross compiler and NOT windows).

The ugly patch I did is as follows:

$ diff -u gcc.jam gcc.jam.org

--- gcc.jam     2008-10-27 16:02:18.406250000 +0200

+++ gcc.jam.org 2008-10-27 15:10:49.093750000 +0200

 }

 .IMPLIB-COMMAND = ;

-if [ os.on-windows ] && !  --cross-compile in [ modules.peek : ARGV ]

+if [ os.on-windows ]

 {

     .IMPLIB-COMMAND = "-Wl,--out-implib," ;

     generators.register

I inserted an artificial parameter in bjam:

Bjam … --cross-compile ...

And combined with the patch above it avoids assigning .IMPLIB-COMMAND = "-Wl,--out-implib," 

I didn't it in a more accurate way because I still don't fully understand jam…

Now I'll be able to begin test it ( I hope it works :) )…

Thanks for the help
