CrossGCC FAQ

[Bhattacharya, Soubhik]

Thanks Bill for the nice FAQ. i was following it 
(http://crossgcc.billgatliff.com) to build toolchain for arm-elf on 
i686-pc-linux-gnu host. however, the build failed in the final complete 
gcc build step.

Versions
==========
i'm using binutils-2.14, gcc-3.3.2, and newlib-1.11.0.


More Info
==========
the build failed in the directory 
/opt/soubhik/temp/crossgcc/build-gcc/arm-elf/thumb/libstdc++-v3/libsupc++

the build terminated with following messages :

i've attached both make.log and configure.log, in case if more 
information is required.

Finally, i've succeeded in building the final gcc by configuring with 
--enable-languages=c
