cppcheck and boost

[Lieven de Cock]

While trying to reproduce an issue, I however got a lot of those :

<error file="bar.h" line="0" id="toomanyconfigs" severity="style" msg="The checking of the file will be interrupted because there are too many #ifdef configurations. Checking of all #ifdef configurations can be forced by --force command line option or from GUI preferences. However that may increase the checking time."/>

the problem I wanted to reproduce was that boost/cstdint.hpp was included and cppcheck signals an error on the following snippet from that file :

# if UCHAR_MAX == 0xff
     typedef signed char     int8_t;
     typedef signed char     int_least8_t;
     typedef signed char     int_fast8_t;
     typedef unsigned char   uint8_t;
     typedef unsigned char   uint_least8_t;
     typedef unsigned char   uint_fast8_t;
# else
#    error defaults not correct; you must hand modify boost/cstdint.hpp
# endif

==> # error defaults not correct; you must hand modify boost/cstdint.hpp

Please advice on how to get rid of all this noise ?

adding a -DUCHAR_MAX=255 on the command line should fix this error message.

when you use -D, the --max-configs is automatically changed to 1. if you want you can use for instance --max-configs=10 or --force also to override this behaviour.
