Problems compiling . soft-float

[Carlo Agostini <carlo.agostini@yacme.com>]

Hi  All

Just to introduce the problem, here is a summary of what I have done.
I work on an Linux port on an MIPS tx39(R3000) based hardware without
hw floating point support .
I finally managed to compile the glibc 2.2.5 for an mipstx39el-linux
configuration for 2.2.14 Kernel .

I'm working on a Pentium III PC with RedHat7.1

I used binutils 2.11.2 and gcc 3.0.3

The parameters I have used for configuration were the following:

---- configure glibc-2.2.5 ----

configure --host=mipsel-linux\
       --target=mipstx39el-linux\
--enable-add-ons\
--build=i686-pc-linux-gnu\
--prefix=$PREFIX \
--without-fp -v

I first generated a glibc (just typing make, with the default
Makefiles).
..... problem, it seems that the --without-fp has not the expected
effects.

I am trying to port microwindows on an mips tx39

Then, I tried to pass explicitly -msoft-float to gcc as an argument
.....

Has anyone information about this problem ?

Does anyone know where could I find a set of
floating-point instructions library ?

you can help me ?

Thanking you in advance

Carlo.
