I've extracted 3.0.1 locally and it's compiled with NDK 27:

/Users/anton/dev/src/termux-elf-cleaner [master] > ./termux-elf-cleaner -version
termux-elf-cleaner 3.0.1

I have the following code (echo.cpp):

#include <iostream>
int main() {
 for (int i = 0; i < 10; ++i)
   std::cout << "Hello................ " << std::endl;
return 0;
}

compiled with CMake into the aarch64 executable.

CMakeLists.txt is the following:

set(CMAKE_EXE_LINKER_FLAGS "-static -ffunction-sections -fdata-sections -Wl,--gc-sections")
add_executable(echo echo.cpp)

Android studio reports it has 4Kb LOAD section alignment (file renamed):

Running termux-elf-cleaner on it silently does nothing:

anton /Users/anton/dev/src/termux-elf-cleaner [master] > ./termux-elf-cleaner /Users/anton/dev/src/project/raw_arm_23/src/main/jniLibs/arm64-v8a/echo
anton /Users/anton/dev/src/termux-elf-cleaner [master] >

File size is the same, MD5 hash is the same.
Is there anything i'm doing wrong?
