CrossCompile bsdiff topic

I want compile bsdiff for android but i have some issue.
- I have download bsdiff source from here http://www.daemonology.net/bsdiff/bsdiff-4.3.tar.gz
- I use this command to compile under Ubuntu

Code:

---

arm-linux-gnueabi-cpp bsdiff.c -o bsdiff -lbz2

---

and

Code:

---

arm-linux-gnueabi-cpp -static  -march=armv7 bsdiff.c -o bsdiff -lbz2

---

but the result file is a text and not a binary, the shell does not output errors.

Thanks
