Oct 20, 2016 · Now I use PRAGMA_WARNING(this need to be fixed) Sadly there is no #pragma warning in gcc, so it warns unspecified pragma. I doubt that gcc will add #pragma warning" rather than microsoft adding #warning.
If the headers don't depend on anything that requires _CRT_SECURE_NO_WARNINGS, then the #define can go after the #includes. – Keith Thompson Commented Apr 16, 2021 at 1:17
All the solutions here failed to work on my VS2013, however, I put the #define _CRT_SECURE_NO_WARNINGS in the stdafx.h just before the #pragma once and all warnings were suppressed. Note: I only code for prototyping purposes to support my research so please make sure you understand the implications of this method when writing your code.
Jan 22, 2017 · 1. POSIX defines a macro M_PI as the value of Pi as an extension to C standard. So, if you are on POSIX system, you don't need to define your own M_PI. But if you don't want to then you can compile only in standard C mode such as: gcc -Wall -Wextra -std=c11 file.c. answered Jan 22, 2017 at 16:39. P.P.
Jan 26, 2010 · 15. In VC if you want the warning to show up in the warning count at the end of compilation you need to use this format: #pragma message(": warning<put what you like here>: blah blah blah") The important sequence is: colon, space, "warning", something or nothing, colon, "your warning text". If you want to be fancy then file and line number can ...
Sep 23, 2008 · i work on a multi platform project, so i can't use _s function and i don't want pollute my code with visual studio specific code. my solution is disable the warning 4996 on the visual studio project. go to Project -> Properties -> Configuration properties -> C/C++ -> Advanced -> Disable specific warning add the value 4996. if you use also the mfc and/or atl library (not my case) define before include mfc _AFX_SECURE_NO_DEPRECATE and before include atl _ATL_SECURE_NO_DEPRECATE. i use this ...
Feb 27, 2010 · #define FOSC 8000000 #define BAUDRATE 9600 #define BRGVAL (FOSC/2)/(16*BAUDRATE)-1 void uart_init(){ U1BRG = BRGVAL; } After the calculation BRGVAL becomes 25.0416667, and because it is not an integer I get the following warning for it when I assign that into U1BRG:
This can be done in GCC using the stringify operator "#", but it requires two additional stages to be defined first. #define XSTR(x) STR(x) #define STR(x) #x. The value of a macro can then be displayed with: #pragma message "The value of ABC: " XSTR(ABC) See: 3.4 Stringification in the gcc online documentation. How it works:
Sep 28, 2012 · 9. If you really want to emit a warning, the following will work, too. However, it depends on C99 being enabled (works with gcc 4.8.2 or later, not tested on earlier versions): #define N 77. #define __STRINGIFY(TEXT) #TEXT. #define __WARNING(TEXT) __STRINGIFY(GCC warning TEXT) #define WARNING(VALUE) __WARNING(__STRINGIFY(N = VALUE)) #if N == 77.
You can use __unused to tell the compiler that variable might not be used. - (void)myMethod: (__unused NSObject *)theObject { // there will be no warning about `theObject`, because you wrote `__unused` __unused int theInt = 0; // there will be no warning, but you are still able to use `theInt` in the future }
