Hmm strange, it works here on macOS. Try edit lib/Transforms/Obfuscation/CMakeLists.txt and add IRReader below interpreter.

[ghost]

Doesn't seems to work?

[Naville]

strange. which version of linux are you using? I only have Windows and macOS installation here and they both seem to link correctly. Temporary workaround would be make clang and just use the clang directly

[ghost]

I'm using archlinux. Kernel version: 4.14.7-1 make clang just gave me this:

make: *** No rule to make target 'clang'.  Stop.

[Naville]

If even clang isn't available, I'm pretty sure among many otherthings , you didn't setup the source base correctly

[ghost]

Mmh. Is that wrong?

$ mkdir obf
$ cd obf
$ git clone ...
$ cmake .../
$ make

[Naville]

First the wiki stated you need to checkout clang and many other stuff separately. The linker error is probably on my side. Will take a look into it in around 8hours

[Naville]

Pushed a fix which should hopefully fix building on Linux. Let me know if it still doesn't

It still doesn't work again :c

[Naville]

I suspect an extra line of required_libraries = IRReader Linker is needed at the bottom of lib/Transforms/Obfuscation/LLVMBuild.txt. Building LLVM in a virtual machine is ridiculously slow and to be honest I couldn't care less about building on other platforms

[Naville]

No idea how the LLVM cmake system works though, but my gut feeling tell me by explicitly introducing dependency like this should hopefully point out the right way to the linkers and stuff

[Naville]

Closing due to inactivity
