openssl is included in the Android operating system, and Google also includes some arm4/thumb assembler code in their builds (aes/asm/aes-armv4.s, bn/asm/armv4-mont.s, sha/asm/sha1-armv4-large.s, sha/asm/sha256-armv4.s, sha/asm/sha512-armv4.s). I have the Android openssl building with ndk-build but it will only builds properly with the plain C aes_core.c, not the arm4 files. It even creates the .o files, but it can't find the *.o.d.org files, which I have no idea where they come from.

Any ideas on this?

I have the exact same problem, and I am looking for a workaround. I am using this version instead: https://github.com/fries/android-external-openssl

I am using the Android NDK r5b

    I actually just found a way to make it work. Reading this: http://osdir.com/ml/android-ndk/2010-06/msg00602.html I edited crypto/Android.mk to put uppercase 'S' instead of 's' to the 5 '.s' files listed at the beginning of the makefile. I also renamed the actual mentioned files from .s to .S, and it now compiles correctly. – awakecoding Feb 10 '11 at 02:40
  • Bingo, that did it for me, I just changed .s to .S in the `crypto/Android.mk`, and it built! – Hans-Christoph Steiner Feb 10 '11 at 19:37

    According to the [gcc docs](http://gcc.gnu.org/onlinedocs/gcc-3.4.6/gcc/Overall-Options.html), a .s is "Assembler code" and a .S is "Assembler code which must be preprocessed". Perhaps the original Android dev who did this work is on a Windows or Mac OS X box, which do not have case-sensitive file systems... – Hans-Christoph Steiner Feb 10 '11 at 19:45
