I use python bindings of libclang.
Source files are correct. Build works fine.
I pass compile_commands.json to libclang parser.
And I’ve written this snippet in python :
def do_cparse(srcFile : str, index : clang.cindex.Index, compDB : CompilationDatabase, additional_args : list):
def clean_commandLine(args : list):
del args[0]
i = 0
while i < len(args):
if args[i] == ‘-c’ or args[i] == ‘-o’:
del args[i]
del args[i]
else:
i += 1
return args
if compDB is not None:
compileCommands = compDB.getCompileCommands(srcFile)
if compileCommands is None:
args = []
else:
args = compileCommands.getitem(0).arguments
args = [arg for arg in args]
args = clean_commandLine(args)
else:
args = []
try:
tu = index.parse(srcFile, args.extend(additional_args))
except TranslationUnitLoadError:
pass
#from pprint import pprint
#pprint((‘nodes’, get_info(tu.cursor)))
for diagnostic in tu.diagnostics:
print(diagnostic.format() + ‘\n’)
But diagnostics deliver this :
/usr/include/limits.h:123:16: fatal error: ‘limits.h’ file not found
/usr/include/stdio.h:33:11: fatal error: ‘stddef.h’ file not found
/usr/include/stdlib.h:32:10: fatal error: ‘stddef.h’ file not found
/usr/include/unistd.h:229:10: fatal error: ‘stddef.h’ file not found
It seems libclang goes wrong. Is it a known issue ?
More, project C-headers are also affected while -I is passed to Index.parse().
Thanks a lot for your contributions.

Didier.
