  • BuildWarnings

    v14 v15  
    11Warnings seen during the build don't necessarily warrant tickets of their own, since they aren't breaking the build. However, one of our goals is to have a (nearly) warnings-free build, so if your build has warnings, document them here, and someone may eventually be able to fix them or update {{{config/auto/warnings.pm}}} to stop complaining about them.

    5 nwellnhof: I just fixed a bunch of warnings. This is what I get with Debian unstable, i386, GCC 4.4.5, non-optimized

    7 The following are caused by -Wbad-function-cast and can be avoided by removing the cast. I'm not sure if this is safe for g++.

    9 {{{ 
    10 src/hash.c: In function ‘Parrot_hash_thaw’: 
    11 src/hash.c:681: warning: cast from function call of type ‘INTVAL’ to non-matching type ‘enum <anonymous>’ 
    12 src/hash.c:682: warning: cast from function call of type ‘INTVAL’ to non-matching type ‘enum <anonymous>’ 
    13 src/nci/signatures.c: In function ‘Parrot_nci_sig_to_pcc’: 
    14 src/nci/signatures.c:184: warning: cast from function call of type ‘INTVAL’ to non-matching type ‘enum <anonymous>’ 
    15 }}}

    17 Calls to parrot_hash_put with const keys or values: 
    18  
    19 {{{ 
    20 src/runcore/main.c: In function ‘parrot_hash_oplib’: 
    21 src/runcore/main.c:345: warning: cast discards qualifiers from pointer target type

    23 src/runcore/main.c:349: warning: cast discards qualifiers from pointer target type 
    24 }}} 
    25  
    26 These could be fixed with a temporary variable:
