error: call to non-‘constexpr’ function ‘long int sysconf(int)’

[acgc99]

Hi,

I'm trying to run the code in binder and I get the next error (in my local machine I get the same)

I execute this:

# build and imports
import sys
import os
import seaborn as sns
from pandas import DataFrame
pathToCsaranshPP = ".."
sys.path.append(pathToCsaranshPP)
from csaranshpp import getDefaultConfig, writeResultsToJSON
buildDir = os.path.join(pathToCsaranshPP, "_build")
libPath = os.path.join(buildDir, "libcsaransh-pp_shared.so")  # path to csaransh library
!mkdir ../_build
!cd ../_build && cmake .. && cmake --build .
if (not os.path.exists(buildDir) or not os.path.exists(libPath)):
    print("Library not found. Might be due to build errors in cmake.")
    print("If built successfully, specify correct build directory & lib file (so / dlib / dlib) above.")

And this is the error:

mkdir: cannot create directory ‘../_build’: File exists
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.
