Bug 98572 – wxWidgets header <wx/wx.h> not including <wx/socket.h>

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Tommy McDaniel 2005-07-10 09:32:06 UTC]

The wxWidgets header file <wx/wx.h> is supposed to include all wxWidgets header  
files, so that one doesn't have to include them each manually. However, after  
receiving some compilation errors, I behold that my /usr/include/wx/wx.h  
doesn't include <wx/socket.h>. This strikes me as something that might very  
well be a bug in wxWidgets itself (or maybe even a feature) and not Gentoo's 
installation of it, but I don't know, and I remember once seeing a request to 
file bugs with Gentoo first (and the developers here would send the bug 
upstream if the problem is with the package itself).  

Reproducible: Always
Steps to Reproduce:
1. Install wxWidgets through Portage. 
2. Take a look at /usr/include/wx/wx.h, or alternatively, compile a program 
using a class like wxIPV4address while only including <wx/wx.h>. 
3. Behold that <wx/wx.h> doesn't include <wx/socket.h>. 
Actual Results:  
I saw that /usr/include/wx/wx.h doesn't include <wx/socket.h>, after getting 
compilation errors when using classes from <wx/socket.h> but only including 
<wx/wx.h>. 

Expected Results:  
Included <wx/socket.h> automatically.

wx/wx.h is not supposed to include every header, only the most used ones. wx/socket.h is apparently not deemed to be used that often, and I agree there. If you disagree, then you should check out the feature request/bug tracker of wxWidgets.

See the wxWidgets manuals "Multi-platform development with wxWidgets" -> "Include Files" topic for reference:
"The main include file is "wx/wx.h"; this includes the _most commonly_ used modules of wxWidgets." (emphasize mine)

Not a bug.

[Comment 3 Tommy McDaniel 2006-04-18 16:26:17 UTC]

One gets the opposite impression from the last of the following sentences taken from their Hello World sample: "You have to include wxWidgets' header files, of course. This can be done on a file by file basis (such as #include "wx/window.h") or using one global include (#include "wx/wx.h")." Oh well, I see what you mean.
