Issue

Im trying to use libHikari.so (built from HikariObfuscator/Hikari, this step) as a -fpass-plugin with Clang builded with llvm-project (this step). However, im encountering a symbol resolution error:

error: unable to load plugin '/home/vboxuser/ndk-obf/toolchains/llvm/prebuilt/linux-x86_64/lib/libHikari.so': 'Could not load library '/home/vboxuser/ndk-obf/toolchains/llvm/prebuilt/linux-x86_64/lib/libHikari.so': /home/vboxuser/ndk-obf/toolchains/llvm/prebuilt/linux-x86_64/lib/libHikari.so: undefined symbol: _ZTVN4llvm2cl6parserImEE 1 error generated.

Envinronment

• OS: Ubuntu 24.04 LTS (VirtualBox)
• Plugin: libHikari.so, built with this step
• Clang version (./clang --version):

clang version 18.0.0git (https://github.com/OPSphystech420/HikariObfuscator_Guide.git 6a276a521f69e8e2f4de5683a232891ec2c07ea2) Target: x86_64-unknown-linux-gnu Thread model: posix InstalledDir: /home/vboxuser/workspace/HikariObfuscator_Guide/Hikari/android-llvm/build/bin/.

Hello.
Thank you, and I am sorry for late response, haven't seen your report.
libHikari.so was built expecting Clang symbols to be available at load time, but clang process you are running does not export those symbols or they come from a different build, so dynamic loader can’t resolve vtable _ZTVN4llvm2cl6parserImEE
Where specifically are you using your libHikari.so?
What CC and CXX are you using?

Steps here should resolve such error, unless you have incorrectly configured the build or used environment variables incorrectly, for example, сonfiguring and building LLVM with a different clang from what you used for hikari is wrong. Incorrect porting of libHikari.so to the project may also give such issue.

Another solution to this problem would possibly be linking plugin against LLVM dynamically.

Please provide more details.
