problem during configuring of libstdc++-v3

["Pradip Singh" <pradip.singh@xxxxxxxxxxxxxxx>]

Hi all,

  Thanks for all ur help that i could build the gcc compiler succefully for arm target. 

  After building the gcc compiler for arm-elf target i aganin configured gcc for building it for g++ using the following configurartion option.

 ../gcc-2004-q1a/configure --target=arm-elf --prefix=/root/armLinux/arm_tools --with-cpu=arm1020t --with-arch=armv5te --with-headres=/root/armLinux/arm_tools/arm-elf/include --enable-languages=c,c++ --enable-threads

The gcc and g++ compiler has been built. Also newlibc has also been built. But the problem is during building of the libstdc++-v3. During configurartion of this standard c++ libraries I am getting the following configuration error.

configure: WARNING: No native operations are provided for this platform.
configure: WARNING: They cannot be faked when thread support is disabled.
configure: WARNING: Thread safety of certain classes is not gauranteed.
configure: error:   no support for this host target combination.

make: *** [configure-target-libstdc++v3] Error 1

I donot understand here even though i am enabling the thread support during configuration why it is giving the second WARNING as thread is disabled. Now i saw in the libstdc++-v3/config folder support for arm was not there. Is it that this library cannot be made to run on arm achitecture. If this is the case any version of libstdc++ is there which can be made to run on arm.

Any help will be appreciated.

thanks and regards,
Pradip
