AArch64 Linux → Android (Termux) compatibility notes
On Android/Termux, native executables use Bionic, not glibc, and the dynamic linker is typically /system/bin/linker64. Termux’s execution environment is different enough that patching a glibc binary to use Android’s linker is usually not sufficient.
if we want to download a binnary we should check *-aarch64-unknown-linux-musl and maybe not work.
inspect
file ./bin
readelf -hW ./bin | grep Type:
readelf -lW ./bin | grep INTERP
readelf -dW ./bin | grep NEEDED
key rule
if we ckeck a musl binary ./bin and we get:
ARM64 + static + ET_EXEC + no INTERP
Native Android wants:
ARM64 + PIE (ET_DYN) + Android/bionic-compatible build
decision
| case | status |
|---|---|
| ET_DYN + INTERP | patchable |
| ET_DYN (static PIE) | likely OK |
| ET_EXEC (static) | ❌ no fix if not musl |
| ET_EXEC (dynamic) | ❌ no fix |
| glibc-linked | ❌ incompatible |
patch (dynamic PIE only)
set Android linker:
patchelf --set-interpreter /system/bin/linker64 ./bin
patchelf --set-rpath '$PREFIX/lib' ./bin
quick reality
static + EXEC→ no path forwardglibc→ wrong libc (Android = bionic)no INTERP→ nothing to patch
This is ABI, not paths.
ET_EXEC → dead
ET_DYN → maybe works
patchelfonly works for dynamic PIE binaries
