Don't really understand this error. It's complaining that an unsigned int
is being assigned a value of (unsigned int)-1
which is allowed. The complaint is that it's being converted to int
but it's not. The typecast should avoid the error, unless this is some new 32-bit vs 64-bit error?
Maybe this is a bug in GCC?
With (unsigned int)-1
you mean max uint? There's a const defined for that
IIRC.
It's not really max uint, it's more a magic number that's very unlikely to be used. It would be a shame if (unsigned int)-1
no longer works, because IMHO that's clearer than something like UINT_MAX
, which suggests you want a really large number for some reason.
I see. Sounds like @Malvineous is against latest ANSI C guidelines. If I'm not mistaken this is kind of out of scope of adplug/adplay (plz excuse me).
reverting this commit fix the issue with gcc8
https://github.com/adplug/adplay-unix/commit/48dcaa87ff91369eb41998abd72e226fe138b528
@ildar Not against the guidelines, I just think that readable code is more important than following someone else's rules. Now that I think about it, it would be even better to do something like #define SUBSONG_NONE xxx
so if someone wants to submit a patch for that I will happily apply it.
@rosset Thanks for finding the breaking commit. Looks like we can't remove the cast or a compiler warning will return with GCC < 8, so using a #define
along with ildar's suggestion of UINT_MAX
or similar is probably the way to go.
The magic number ~0
is all bits set
(the reason the compilation fails is due to -Werror, causing all warnings to be become errors)
@Malvineous, you decide if you want to change the code or not, and close this issue as you see fit.
