Yes, definitely interested by the log. I don't compile CImg often with clang, but I think I'll have to try again :)
π the vsprintf one:

(and thx for the great lib BTW)
David, I've just installed clang-12
but cannot get the same warning.
If you replace the problematic line by:
const int result = std::vsnprintf(s,(size_t)~0U,format,args);
do you still get a warning ?
EDIT: Installed clang-14
on a VM (Ubuntu 22.04) and still don't get your warning. Maybe a MacOSX-specific stuff?
π for the vspnrintf thing, no more warning. Thx
For clang14, I agree that with default settings, the implicit conversion warnings are not raised. When used in Xcode or the xcodebuild command line, extra warning flags seem to be added and I've got the trace I sent you.
Let me try to get the build parameters Xcode is using...
FYI, I've posted a new .zip archive on the main website, with the fix included. Cheers.
David.
ππthx
When using the current release
CImg-3.2.0_pre110222/CImg.h
, I'm having a lot of warnings (mostly depreciation onvspintf
usage and implicit conversions that lose precision).Is there a way to globally disable
CImg.h
warnings when used in another project ?Would you be interested in having the list of warnings I get ?
(clang 14, default compiler on macOS Ventura)
