I've successfully built V8 for my Samsung S3C2440AL-40N
Maybe my previous investigations will help you
So, it works with these lines :
export GCC_VERSION=44
export CC="<path_to_your_crosschain>/arm-linux-gcc"
export CXX="<path_to_your_crosschain>/arm-linux-g++"
export CXXFLAGS="-I. -mcpu=arm920t"
export CFLAGS="-I. -mcpu=arm920t"
scons mode=release arch=arm library=shared prof=off os=linux
profilingsupport=off snapshot=off
I'm using a fake execinfo.h I just put at the root of the project to
deal with backtrace errors during compiling.
#ifndef _EXECINFO_H_
#define _EXECINFO_H_ 1
#include <sys/cdefs.h>
__BEGIN_DECLS
int backtrace(void**,int){ return 0; }
char** backtrace_symbols(void* const*,int){return NULL; }
void backtrace_symbols_fd(void* const*,int,int){}
__END_DECLS
#endif /* !_EXECINFO_H_ */
And because I discovered a small bug in the code for ARM some weeks
ago, it has been fixed in the trunk
http://groups.google.fr/group/v8-users/browse_thread/thread/8dd63321fd680434/d056f61c50449926
So you have to use the trunk to get the patch for arm
I hope it will work for you
