# When FIXPATH is set, let it process the file to make sure all paths are usable
|
|
# by system native tools. The FIXPATH tool assumes arguments preceeded by an @
|
|
# character points to a text file containing further arguments (similar to a
|
|
# linker). It replaces any such arguments with a different temporary filename,
|
|
# whose contents has been processed to make any paths native. To obtain a
|
|
# properly processed compile_commands.json, FIXPATH is then made to invoke an
|
|
# AWK script with the unprocessed json file as the only argument, prepended with
|
|
# an @ character. The AWK script simply copies the contents of this processed
|
|
# file.
