c cwa-convert - Absolute path of .cwa file not working under UNIX systems.

I had the same issue and for some reason it didn't go away when I removed the forward slash part; however, I've written a pretty straightforward Python function to automatically modify the full path into an equivalent relative path. You just need to write the proper path to the cwa-convert build in CWA_CONVERT_CMD_PATH:

import os
import subprocess


# note: first, openmovement git repo has to be cloned, then the C library must be built.

CWA_CONVERT_CMD_PATH = '/path/to/openmovement/Software/AX3/cwa-convert/c/cwa-convert'
# note: C code has a bug where it can't read an argument starting with '/' as a file
#       so we need to specify the number of "../" prefixes to put...

def convert_cwa_to_csv(input_filename, output_filename):
    # make sure that we have gotten full path to input_file
    if input_filename[0] != '/':
        # TODO{try to handle non-full-paths by using glob.iglob and inferring the proper path.}
        raise Exception('Must specify full path. i.e. /path/to/file.ext')
    filename = input_filename.split('/')[-1]
    pwd = os.getcwd()
    num_directory_levels_up_to_go = len(pwd.split('/')) - 2
    input_dir_prefix = '../' * num_directory_levels_up_to_go
    full_input_path = input_dir_prefix + filename

    subprocess.run([CWA_CONVERT_CMD_PATH, full_input_path, '-out', output_filename])

Sorry this took so long to fix. Thanks for the original report @NarayanSchuetz and recent comment @adamcatto that notified me that this was still an issue. Fixed in a82452f
