Pragma for disable warnings

[Victrix]

Hi all

Well, i love set to on all warning compiler flags because then i get more information about my code, im using C::B, MinGW and wxWidgets (on Windows plataform), but when i set on the warning flags (-Wall, -W, -pedantic), the rebuild project take a lot of time (cant remember, but i think more than 1 hour) when the compiler get to "#include <wx/wx.h>" line, there is a way to disable the warnings flags when the compiler reach the "#include <wx/wx.h>" line, maybe a pragma directive, i was looking for in MinGW documentation (GCC Manual and other sources), but couldnt find nothing .

For now if i need rebuild project i need to turn off all warning flags and rebuild, but if i forget (lol, i think i forget 4/5) set warnings off i have to close C::B, kill some process not closed when C::B do (cc1plus.exe, mingw32-g++.exe) and then reload all again.

Well, thanks in advance for your help.

Sorry by my bad english

-Wall is fine, but compiling anything that uses wxWidgets with -pedantic is simply impossible.
Hey, we're talking about wxWidgets...  :lol:

The reason why it takes so long to build your project is that literally gigabytes of warning messages are being piped to the log window during the build.

As a sidenote:
As you all know, compiling wxWidgets from source takes quite some time, too, especially with gcc.
One day, Tiwag gave me the tip to add 1>nul 2>nul to the commandline, so the 15 million warning messages would go down the drain right away instead of being piped to the console.
Guess what: this cuts the build time to one half!


EDIT: Sorry, I just saw that I did not answer to the question at all. gcc has no such pragma. What could possibly help is to put everything wx-related into one target (if that's possible) and turn off the -pedantic switch in that target.

Great tip!

I suggest to remove the -W flag too, every time you don't initialize a structure member you get a warning...
-Wall is enough, i suppose
