CPPcheck with JSONDB file shows no errors

[Karsten Beck]

The basis of this problem is the topic https://sourceforge.net/p/cppcheck/discussion/general/thread/608af51e0a/?limit=25#98b6
(CPPcheck does not include files from the Project Options)

@danielmarjamaki recommended to include the project via JSONDB -file. IAR as of version 9 can create a JSON file from the project, which I passed to CPPcheck.
However, the output now only shows functions that are not used [unusedFunction].
If I check the files individually (passed directly) or the entire project (project directory), then various other errors are displayed. However, when using the JSON file, they do not.

Doesn't anyone have any ideas on how I can proceed?

[Karsten Beck]

@danielmarjamaki Do you have any idea where the problem might be?

[Daniel Marjamäki]

There has been a couple of fixes in the import of compile databases. If you want you could try to install cppcheck-2.7.5 and see if issues has been fixed.

Hi @danielmarjamaki
thank you very much for your answer. I just installed version 2.7.5 and then nighty build 776. Both throw a syntax error with the last closing ] brace of the json file when calling the compile-database file.
Checking the file with https://jsonlint.com/ showed that it is error-free.

Is there maybe another bug here?

D:\Projekte\xyz\firmware\app\Debug>c:\Programme\Cppcheck\cppcheck.exe jsondb.json
Checking jsondb.json ...
jsondb.json:881:1: error: syntax error [syntaxError]
]

Best wishes

try:

D:\Projekte\xyz\firmware\app\Debug>c:\Programme\Cppcheck\cppcheck.exe --project=jsondb.json

UPDATE:
This is no error, wrong syntax from me. Correct would have been:
`D:\Projekte\xyz\firmware\app\Debug>c:\Programme\Cppcheck\cppcheck.exe --project=jsondb.json``
With this it works!

Thanks a lot!
