Cross-compiling for Android

Question

I'm trying to cross-compile dropbear for android. The files appear to compile find, but when executed give "program : not found." I did a find and the libraries marked NEEDED appear to be located in the cross-compile environment. I have compiled other programs with this toolchain.

arm-none-linux-gnueabi-readelf -d dropbear

Dynamic section at offset 0x1c158 contains 27 entries:

Answer 1

Did you apply the "patch" to dropbear, because dropbear uses /etc/passwd and that does not exist on android.

Found this on Installing Dropbear - MyWiki

Dropbear needs to be patched to work with Android. Android does not use a ‘/etc/passwd’ file, so that needs to be patched together with some directory changes. This also adds a statically password. This password is located at the bottom of ‘debug.h’ in the dropbear directory. The default password is “password”. The patch can be found here: http://pastebin.com/f3dedc5e7

I know dropbear can compile and run on android because CyanogenMOD, along with most of the other ROMs I have used have it on the system.

Answer 2

I found the problem. I was compiling w/o the STATIC=1 flag. Thanks for the reply! Thanks for the reply! I got the patched source from cyanogen's github
