Can not Load Key Generators

i guess it trying to load/use theis module which is part of package i compile with new testing gcc-2.95.3 fpa native toolchain

i get the feeling from looking around it could be result of a few things...

if my path is set to default vfp toolchain i get:
# ldd /usr/lib/ => /lib/ (0x40011000)
       /lib/ => /lib/ (0x2aaaa000)

if my path is set to the new toolchain i get:

# ldd /usr/lib/ => /lib/ (0x40011000)
       /opt/native/arm/2.95.3-armv4l-hardfpa//lib/ => /opt/native/arm/2.95.3-armv4l-hardfpa//lib/ (0x2aaaa000)

and if i add my new toolchain's /lib to the LD_LIBRARY_PATH i get :

# ldd /usr/lib/ => /opt/native/arm/2.95.3-armv4l-hardfpa/lib/ (0x40012000)
       /opt/native/arm/2.95.3-armv4l-hardfpa//lib/ => /opt/native/arm/2.95.3-armv4l-hardfpa//lib/ (0x2aaaa000)

maybe it has some thing to so with the source code for the module ??

for example i found this on a site out there:

AsIDE will now automatically create an Intel-HEX format file after every build.
I'm getting getting a linker error undefined reference to `__divsi3' when I build my application. Why?
You need to link in the library libgcc.a. Within AsIDE:
1. Select Project|Project Properties|Tools
2. Select Link in the Tool name list
3. Click the Options... button
4. Add the following line to Libraries/Objects:

-L %(GCC_EXEC_PREFIX)\arm-elf\3.3.1 -lc -lgcc

Where -lgcc is shorthand for libgcc.a. AsIDE will now automatically link in libgcc.a after every build.

maybe something similiar could help... ?
(i think its an old gcc thing)

yep, just add the following to the end of the linker command ( $(LD) $(OBJ) -soname $(TARGET) -o $(TARGET) -lc) in the Makefile for the .o file::

-L/opt/native/arm/2.95.3-armv4l-hardfpa/lib/gcc-lib/armv4l-unknown-linux-gnu/2.95.3/ -lgcc

ie path to libgcc.a which defines __divsi3 among other goodies wink.gif
