Architect

Architect is a utility that wraps one or more binaries allowing the resulting binary to be run on both ARMHF and ARMEL Kindles.

Usage

1. Compile this program using meson setup builddir_ARCH & meson compile -C builddir_ARCH
2. Add the armel and armhf target binaries to the compiled program:
   1. objcopy --add-section .sf_payload=target_sf architect architect
   2. objcopy --add-section .hf_payload=target_hf architect architect
3. Done! The final binary will now run on both armel and armhf Kindles

Notes

The hf_payload section is optional as armel binaries should be able to run under the armel interpreter.

How does it work

1. Check system architecture
2. Get the required interpreter and binary data
3. Create a temporary file & write target payload to it
4. Fork
   1. Execute the temporary file
5. Wait for subprocess to exit
6. Delete the temporary file
