Unable to install library

[kirtsar]

Hello!
For some reasons i was unable to install library properly: it says that "lib_SyndromeDecodingEstimator.so: cannot open shared object file: No such file or directory"

Full trace of the make installation:

Hi kirstar,
sorry for the delayed reply. The issue is that the estimator is not finding the C-library. According to the trace it was installed to /usr/local/lib/lib_SyndromeDecodingEstimator.so. We are currently working on a version which does not require any C-code anymore. But until this is released, as a workaround you could try to add the path of the library to your PATH environment variable.

@kirtsar Please try:

LD_LIBRARY_PATH="/usr/local/lib" python estimate_code_based_nist_schemes.py

Have you solved this problem?

He said we need to download this shared library from GitHub, but where exactly do we download it from?
