Thread: Enabling -Weverything for a part of code in Clang

Hi,

I want to enable -Weverything for a piece of C code using LLVM Clang compiler.
Why the following does not work for me , what should I do ?

Code:

#pragma clang diagnostic push
#pragma clang enabled "-Weverything" 

// Some code

#pragma clang diagnostic pop

I don't think "-Weverything" is correct, either. (Are you sure that exists?)

Although not much recommended it exist , visit here.

Code:

#include <stdio.h>
 
int main() {
    int a = 1;
    unsigned b = 2;
 
    if (a > b) printf("yep\n");
 
#pragma clang diagnostic push
#pragma clang diagnostic warning "-Wextra"
 
    if (a > b) printf("yep\n");  // warning: comparison of integers of different signs
 
#pragma clang diagnostic pop
 
    return 0;
}

I still get some warnings that show #pragma does not work correctly yet:

Code:

#pragma clang diagnostic push
#pragma clang diagnostic warning "-Wall" 

// Some code

#pragma clang diagnostic pop

I get these:

Code:

backend.c: At top level:
backend.c:14468:0: warning: ignoring #pragma clang diagnostic [-Wunknown-pragmas]
 #pragma clang diagnostic push
 
backend.c:14469:0: warning: ignoring #pragma clang diagnostic [-Wunknown-pragmas]
 #pragma clang diagnostic warning "-Wall" 
 
backend.c:14507:0: warning: ignoring #pragma clang diagnostic [-Wunknown-pragmas]
 #pragma clang diagnostic pop

By the way I am using a make-file rather than an IDE (Code::Blocks) project. In case it matters.

I guess it has to be asked: are you sure you're using clang and not gcc or something else?

Edit: to be more specific, are you sure the makefile is using clang as the compiler? Maybe paste the output of the make process

I still use Code::Blocks IDE with a custom make-file.
