Running c code in ARM QEMU

I created and Compiled a C program to run in QEMU for ARM.
When I run the program using the command
#qemu-arm -L /home/arm-2010.09/arm-none-linux-gnueabi/libc ./test

it gives me the following error:
If 'qemu-arm' is not a typo you can use command-not-found to lookup the package that contains it, like this:
    cnf qemu-arm

In PATH is have added the path to /el/el_test/arm-2010q1/bin but still I get the error.
What is the reason for this?
How to resolve this issue?

ragg2 -- radare2 utility to run programs in exotic environments SYNOPSIS
ragg2 [-a arch] [-b bits] [-k kernel] [-f format] [-o file] [-i shellcode] [-I path] [-e encoder] [-B hexpairs] [-c k=v] [-C file] [-d off:dword] [-D off:qword] [-w off:hexpair] [-p padding] [-FOLsrxvh] DESCRIPTION
ragg2 is a frontend for r_egg, compile programs into tiny binaries for x86-32/64 and arm. This tool is experimental and it is a rewrite of the old rarc2 and rarc2-tool programs as a library and integrated with r_asm and r_bin. Programs generated by r_egg are relocatable and can be injected in a running process or on-disk binary file. ragg2-cc is another tool that comes with r2 and it is used to generate shellcodes from C code. The final code can be linked with rabin2 and it is relocatable, so it can be used to inject it on any remote process. ragg2-cc is conceptually based on shellforge4, but only linux/osx x86-32/64 platforms are supported. DIRECTIVES
The rr2 (ragg2) configuration file accepts the following directives, described as key=value entries and comments defined as lines starting with '#'. -a arch set architecture x86, arm -b bits 32 or 64 -k kernel windows, linux or osx -f format select binary format (pe, elf, mach0) -o file output file to write result of compilation -i shellcode specify shellcode name to be used (see -L) -e encoder specify encoder name to be used (see -L) -B hexpair specify shellcode as hexpairs -c k=v set configure option for the shellcode encoder. The argument must be key=value. -C file include contents of file -d off:dword Patch final buffer with given dword at specified offset -D off:qword Patch final buffer with given qword at specified offset -w off:hexpairs Patch final buffer with given hexpairs at specified offset -p padding Specify generic paddings with a format string. -F autodetect native file format (osx=mach0, linux=elf, ..) -O use default output file (filename without extension or a.out) -I path add include path -s show assembler code -x execute (just-in-time) EXAMPLE
$ cat hi.r /* hello world in r_egg */ write@syscall(4); exit@syscall(1); main@global(128) { .var0 = "hi!0; write(1,.var0, 4); exit(0); } $ ragg2 -O -F hi.r $ ./hi hi! $ cat hi.c main() { write(1, "Hello0, 6); exit(0); } $ ragg2 hi.c $ ./hi.c.bin Hello SEE ALSO
