Missing link library

Missing link library LLVMInterpreter in CMakeLists.txt L:41

This results in the inability to compile.

Backend error - inconsistency in registered commandline options

I try to compile a test code:

#include <stdio.h>

int main(){
	printf("Test print\n");
	return 0;
}

The command line is the following:

I am on Debian 64 bits 6.5.0. I have tried with clang versions 14 to 17, resulting in the same issue. The only difference is that -fno-legacy-pass-manager is not supported after version 15.

I have also tried compiling different files for different architectures, still no difference. I guess the .so obfuscator needs to be compiled with specific flags ?

Incompatability with Current Nightly Toolchain

Hi, put together a project build recently that was working perfectly during compile time however now I am starting to see a consistent crash when building core for an invalid reference which terminates the build.

Rechecked the Rust obfuscation guide but I suspect there could be some incompatibility with newer nightly builds.
Any help appreciated. Let me know if you want any error logs etc.

The error returned when building libc and other core libraries appears to be: undefined reference 'diagnostic-width

Problew with build the compiler and LLVM

I use the guide and trying to adapt it for Windows OS, when I run the command python .\x.py build, I get thread 'main' panicked at 'shared linking to LLVM is not currently supported on x86_64-pc-windows-msvc', src\bootstrap\native.rs:162:13 .
Is there any way to do this on Windows?

Good afternoon.
I followed the manual for rust and ran into a problem building obfuscate-llvm. There were no deviations from the manual until make -j8 command in 3. Build the obufscation section. I've tried both branches, nothing changed.

I would be extremely grateful for any help, as extremely interested in using this project.

Error when cross compiling plugin on Apple Silicon

Hi @PatriceBlin I've been having some issues trying to build the plugin locally. I've been following your guide on how to do this with the android NDK.

I'm trying to do this for NDK r25 revision r450784d.

Environment is macOS 13.6 with an Apple Silicon chip.

LLVM_HOME is set to: ~/tmp/llvm-toolchain/out/stage2-install/
LLVM_DIR is set to: $LLVM_HOME/lib64/cmake
TOOLCHAIN is ~/tmp/android-ndk-r25/toolchains/llvm/prebuilt/darwin-x86_64
CXX_HEADERS is set to: $LLVM_HOME/include/c++/v1 but I've tried these as well:
android-ndk-r25/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include/c++
android-ndk-r25/toolchains/llvm/prebuilt/linux-x86_64/include/c++

When I try to build the plugin I get the following:

$cmake -S ~/obfuscator-llvm -B ~/tmp/llvm-obfuscation-ndk -D LLVM_DIR="$LLVM_DIR" -D CMAKE_CXX_COMPILER=$CXX -D CMAKE_CXX_FLAGS="$CXXFLAGS"

-- Configuring incomplete, errors occurred!```

Looks like either I have a completely broken clang in my NDK installation, or I'm missing something crucial for it to work.

I have applied the fixes to `CryptoUtils.h` and `CMakeLists.txt` from the macOS build fix branch already, and I've tried some things you mentioned in #6 without success.

Do you have any thoughts? Thanks in advance.

P.S.: If you have any guidance on how to use the plugin through gradle afterwards, that would be great too.

Trouble building/using Android toolchain

Hi,

I'm having difficulties building and using the obfuscator with Android.

I am following the instructions on https://github.com/eshard/obfuscator-llvm/blob/main/docs/ANDROID_NDK.md

I tried using the latest NDK (r25b) as well as the one documented on the page (r23b - but I had to revert the latest changes for llvm 14 in order to make the plugin build)

First of all, I believe --no-build windows --no-build lldb should be changed into --no-build "windows,lldb" (with r25b both worked, but with r23b the two-separate option ended up building windows tools anyway)

Then, the instruction says 'Compile the plugin with -D LLVM_DIR=~/tmp/llvm-toolchain/out/stage2-install/lib64/cmake along with a NDK compile environment.' but the code below initializes LLVM_DIR to '${LLVM_HOME}/lib64/cmake'. I believe the first one is correct, please confirm.

With the above changes, I am able to build libLLVMObfuscator.so but using it gives undefined symbols:

/home/spop/obfuscator/android-ndk-r25b/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android23-clang++ -I/home/spop/obfuscator/android-ndk-r25b/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include -I/home/spop/obfuscator/android-ndk-r25b/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include/aarch64-linux-android -O1 -fno-legacy-pass-manager -fpass-plugin=out/libLLVMObfuscator.so -c foobar.cpp -o foobar.o error: unable to load plugin 'out/libLLVMObfuscator.so': 'Could not load library 'out/libLLVMObfuscator.so': out/libLLVMObfuscator.so: undefined symbol: _ZNSt6__ndk112basic_stringIcNS_11char_traitsIcEENS_9allocatorIcEEED1Ev'

Any idea ? Thanks !

Obfuscation not being applied

I'm successful in building LLVM and the obfuscation plugin, however I'm unable to apply the obfuscation passes. What am I missing here?

main.c

#include <stdlib.h>
int main(int argc, char** argv) {
  int a = atoi(argv[1]);
  if(a == 0)
    return 1;
  else
    return 10;
  return 0;
}

(https://github.com/heroims/obfuscator/wiki/Bogus-Control-Flow)

Compile without obfuscation

clang main.c -o main

Compile with obfuscation

export LLVM_OBF_SCALAROPTIMIZERLATE_PASSES="flattening, bogus, substitution, split-basic-blocks"
clang  -fno-legacy-pass-manager -fpass-plugin=/obfuscator-llvm/build/libLLVMObfuscator.so main.c -o obf

Compare binaries

diff main obf

Binaries are the same. I've also tried:

export LLVM_OBF_PEEPHOLE_PASSES="flattening, bogus, substitution, split-basic-blocks"
export LLVM_OBF_SCALAROPTIMIZERLATE_PASSES="flattening, bogus, substitution, split-basic-blocks"
