Hi, I have found the same bug. Cheers
Hi @robsonos and @marco86to,
Here is line 7 of Polyfills/preprocessor.hpp
:
#define ARDUINOJSON_CONCAT_(A, B) A##B
There is no error here!
Also, I ran cppcheck 2.10 on this file and got no error.
Best regards, Benoit
Hi @bblanchon,
For more context, I am using platformio/tool-cppcheck
from PlatformIO.
I did some testing and coundn't find any issues with the macro expansions of ARDUINOJSON_VERSION_NAMESPACE
and ARDUINOJSON_CONCAT_
. I wonder if the issue is related to cppcheck
itself like in https://community.platformio.org/t/wrong-issues-from-cppcheck/18410/7.
In terms of PlatformIO itself, the following will suppress the error:
check_flags =
cppcheck: --suppress=*:*.pio\*
Hi,
Just reporting this issue while running
cppcheck
:...ArduinoJson/src/ArduinoJson/Polyfills/preprocessor.hpp:7: [high:error] failed to expand 'ARDUINOJSON_BEGIN_PUBLIC_NAMESPACE', Invalid ## usage when expanding 'ARDUINOJSON_CONCAT_': Unexpected token ')' [preprocessorErrorDirective]
Cheers
