Warning on OSX

[Igor Korot]

Hi,
I am having a following on the Xcode 9.4.1 on the OSX 10.13.6 compiling
my application with wxWidgets 3.1.5:

[code]
filefn.h
Implicit conversion loses integer precision size_t (aka long) to int
In file included from wxWidgets/include/wx/wx.h:24
In file included from wxWidgets/include/wx/event.h:22
In file included from wxWidgets/include/wx/cursor.h:69
In file included from wxWidgets/include/wx/cursor.h:14
In file included from wxWidgets/include/wx/bitmap.h:21
In file included from wxWidgets/include/wx/image.h:23
In file included from wxWidgets/include/wx/stream.h:21
Expanded from macro 'wxCRT_Readlink'
[/code]

Library was compiled cleanly from the Terminal with

../configure --enable-debug --enable-debug_gdb --with-cocoa --with-cxx=11

I don't see this warning on either Windows or GTK.

Thank you.

Hi,

Did you try with the master, to see if it was not fixed by this or similar:

https://github.com/wxWidgets/wxWidgets/commit/15b06480412b010c9b72e9c734bc79e60e8f8520

Hi, PB,

No.

I'm developing based on the release.

I'll wait for 3.1.6/3.2.0.

Thank you.

Regards,

PB

Hi,

I believe that when reporting an issue with an older release, an attempt should be made to check whether the issue can still be reproduced in the current master. Even more so, when the signature of the function causing the issue has changed and all the testing needed is just to run the build...

So you consider it is better to ask for help from others (for free) for trivial things like this, and not put any effort yourself in finding out whether you are reporting a problem that is already fixed? How do you justify that?

Hi, Lauri,

My E-mail was not directed to ask for help.
It was rather directed to say that this is what I observe and I didn't
see the same behavior on the other platforms.

And so I was very confused because at least on *nix/GTK this warning
should've been produced.

Thank you.

Hi,
The warnings in question are no longer happening.

However I (still) have the same warning from stc.h:

[code]
virtual long XYToPosition(long x, long y) const wxOVERRIDE
{
long pos = PositionFromLine((int)y);
if ( pos == -1 )
return -1;

if ( x >= LineLength(y) ) // in this line
return -1;

pos += x;
return pos;
}
[/code]

Thank you.

This is still an issue in the latest stc.h on GitHub.  In both XYToPosition and PositionToXY, a long is passed to LineLength, which takes int.

Sorry, I don't understand what do you mean. I see explicit cast to int in
XYToPosition() and PositionToXY() passes an int to LineLength() anyhow.
What warning exactly are you getting and with which version of wx?
