Hello On trying to compile the kernel 2.6.22.19 with the gcc 4.3.2 for arm processor, gcc -v is as below Using built-in specs. Target: arm-unknown-linux-gnueabi Configured with: /home/developer/devel/crosscompiler/targets/src/gcc-4.3.2/configure --build=i686-pc-linux-gnu --target=arm-unknown-linux-gnueabi --host=i686-pc-linux-gnu --prefix=/home/developer/x-tools/arm-unknown-linux-gnueabi --with-sysroot=/home/developer/x-tools/arm-unknown-linux-gnueabi/arm-unknown-linux-gnueabi/sys-root --enable-languages=c,c++ --disable-multilib --with-float=soft --with-gmp=/home/developer/x-tools/arm-unknown-linux-gnueabi --with-mpfr=/home/developer/x-tools/arm-unknown-linux-gnueabi --with-pkgversion=crosstool-NG-1.2.0+svn_trunk@1176 --enable-__cxa_atexit --with-local-prefix=/home/developer/x-tools/arm-unknown-linux-gnueabi/arm-unknown-linux-gnueabi/sys-root --disable-nls --enable-threads=posix --enable-symvers=gnu --enable-c99 --enable-long-long --enable-target-optspace Thread model: posix gcc version 4.3.2 (crosstool-NG-1.2.0+svn_trunk@1176) I am getting the below error Can u please tell me if some extra flags, to be used in compiling the gcc, so that the "__aeabi_unwind_cpp_pr0" function gets included with the libgcc. In kernel include/linux/iffies.h there are many macro divisions and i have replaced one of these macros with a varable, and on compilng the kernel , it complains of the undefined __udivdi3 __divdi3 functions , because of this , i am trying to link those functions in the libgcc.a , on doing so i am getting the below error.
