rtems-4.94 build error

[padmakumar at sigtechwireless.com]

 Hello,

 I am new to RTEMS and trying to understand its working.

 My Host environment is Ubuntu 10.04 LTS.

 I have installed the following tools list successfully.

 1. autoconf-2.68
 2. automake-1.11.1
 3. binutils-2.21
 4. gcc-4.5.2
 5. gdb-7.2
 6. gmp-4.3.2
 7. mpc-0.8.1
 8. mpfr-2.4.2
 9. newlib-1.19.0

 Everything build without error and installed successfully.

 then I set the path as ,

 export PATH=/opt/rtems-4.11/bin:${PATH}

 After that I used rtems-4.9.4, with target as ARM and BSP as edb7312. 
 while compiling this, i am getting an error message as follows,
