OSError: /usr/lib/llvm-7/lib//libclang-11.so about transcoder HOT 6 CLOSED

Definitely was a user error on the above comment, but to fix the clang error all I did was open the code_tokenizer.py file and replace line 24 with this, save and exit. --> clang.cindex.Config.set_library_file('/usr/lib/x86_64-linux-gnu/libclang-6.0.so.1')

This worked for me and I was able to get some output.

from transcoder.

Tried both methods, still throwing this error:

During handling of the above exception, another exception occurred:

According to @brozi first commit if libclang-11.so isn't located on /usr/lib/llvm-7/lib/ you must modify ./preprocessing/src/code_tokenizer.py at line 24 from

clang.cindex.Config.set_library_path('/usr/lib/llvm-7/lib/')

To :

clang.cindex.Config.set_library_path("/path/to/lib/clang/libclang-11.so")

from transcoder.

I don't know if you managed to fix your problem but you can also try to downgrade the clang package to version 6.0.0.2 and then locate libclang.so if it is not in /usr/lib/llvm-7/lib/

pip install clang==6.0.0.2

from transcoder.

line 24
clang.cindex.Config.set_library_file('/usr/lib/x86_64-linux-gnu/libclang-6.0.so.1')

and Comment out line 30
#idx = clang.cindex.Index.create()

This repo is now deprecated. Please now refer to our new repository https://github.com/facebookresearch/CodeGen, which solves this issue. Does not use clang anymore !
