SOLVED-+upgraded toolchain with gcc-4.0.2

[Luís Cargnini]

Hi after some e-mails among list me and Vineet Tuli i have generated a
toolchain for omap. But i have made some changes
i have created a new toolchain with following tools:
binutils-2.16.1
gcc-4.0.2
glibc-2.3.6 (+glibc-linuxthreads)

some changes in glibc were nececssary, following the patches for glibc-2.3.6:

=================================================

after compiled glibc i recompiled gcc with the following flags:

../gcc-4.0.2/configure --target=arm-linux --prefix=/opt/arm-linux
--enable-languages=c,c++  --enable-threads --enable-__cxa_atexit
--enable-nls --enable-long-long --enable-c99

why:
 --enable-languages=c,c++

    This option ensures that only the C and C++ compilers are built.
--enable-__cxa_atexit

    This option allows use of __cxa_atexit, rather than atexit, to
register C++ destructors for local statics and global objects and is
essential for fully standards-compliant handling of destructors. It
also affects the C++ ABI and therefore results in C++ shared libraries
and C++ programs that are interoperable with other Linux
distributions.
--enable-c99

    Enable C99 support for C programs.
--enable-long-long

    Enables long long support in the compiler.
--enable-threads=posix || --enable-threads

    This enables C++ exception handling for multi-threaded code.

thats all 8-)
