Compiler Flag -Wall is always present - how to turn off?

(1/1)

Sultaneous:
Hi all,

  I have configured a new (unsupported) c compiler for C::B.  This was done as per the wiki, by copying gcc and configuring the toolchain.

  When I try to compile a simple test program, C::B invokes my compiler with the -Wall flag.  This flag is not supported by my compiler.

  Under Project | Build Settings and under Settings | Compiler, the compiler flag for -Wall is turned off.
  In fact, if I turn it on by checking the box, the compiler is then invoked with 2 -Wall paramaters:  -Wall -Wall ...

  It seems C::B is making the -Wall flag mandatory.  How can I turn this off / change this behaviour?
  No global variables are set, nor is this option listed in any additional or custom flag fields.

Thanks in advance!

Probably the flag has been moved to compiler -> other options. All set but unlisted flags go there. Check all places - global compiler options, project root options, build target options. All of them have the check box control and the other options. So you have 6 places to check. One of them contains it. If you cannot find it you can inspect the cbp file in a text editor. It would give you a clue where to search for the option in the UI.

Thank-you!  You were right, indeed I had to ascii edit the .cbp file, where this node was under project:

<Compiler>
     <Add option="-Wall" />
</Compiler>

Despite not being able to find this in the UI, deleting the node + restarting solved the issue.  Thank-you.

It would have been good if you could have found it. Editing the file by hand is not really recommended.
