Since it was defined here "/Users/bootywarrior/Downloads/Webkit/latest/WebKit/Source/bmalloc/bmalloc/ProcessCheck.h:39:13: note: previous definition is here
inline bool gigacageEnabledForProcess() { return true; }"

Wouldn't be simply to remove the bool from "/Users/bootywarrior/Downloads/Webkit/latest/WebKit/Source/bmalloc/bmalloc/ProcessCheck.mm:35:6: error: redefinition of 'gigacageEnabledForProcess'
bool gigacageEnabledForProcess()" ?

Actually That was the wrong assumption of me considering it falls between the "#if !BPLATFORM(WATCHOS)" check.

Hi bigsea123,
Does this mean your issue is resolved?

Honestly, my gut feeling says that the root cause of your issue is ether:
1. You're missing a #include of some header file somewhere, or
2. Your project is misconfiguring some build-time flags in a way that is not supported by the project.

My bet would be on (1).

Anyway, are you still stuck, or is the issue resolved for you?  Thanks.

The last problem or issue I opened I build for purpose of coverage fuzzying.
https://bugs.webkit.org/show_bug.cgi?id=244751
After *That bug report* was fixed the build fixed 
I Used the same commands and the build worked flawlessly, 
I use the same build command on this commit and it fails with gigacage issues. But no I haven’t got the issue resolved.

[Mark Lam]

@Yusuke, is --jsc-only supported on macOS?

[Mark Lam]

Hi bigsean123, I just noticed that you're using the `--jsc-only` flag for build-jsc on macOS.  This is not an officially supported configuration.  Try removing the `--jsc-only` flag.  build-jsc should only build jsc anyway.

Will try that and give feedback on the results.

Build error

This the result of build-jsc without --jsc-only...

I'm if --jsc-only isn't officially supported for Darwin builds then why was this commit made for my other issue https://github.com/WebKit/WebKit/pull/4015.

Is their any other way around this issue both build-jsc and build-jsc --jsc-only are producing errors, 
Weirdly build-jsc --jsc-only have been building just fine on most commits up until recently within the last month

Best effort to support (as much as possible). Not an officially supported configuration.

Would be helpful if we can actually see what the error is.

[Mark Lam]

BTW, I think `-DENABLE_STATIC_JSC=ON` is another non-supported option for macOS.

I think this might be an artifact of recent build system changes (and yes it's a bug).  Try adding this to your env vars: USE_WORKSPACE=NO.  Let me know if that make the issue go away.  Thanks.

[Mark Lam]

Hi bigsean123, one more thing: have you pulled the latest `main` branch?  Just double checking in case.

[Ben Nham]

From looking at the code it seems that the #defines in ProcessCheck.h and ProcessCheck.mm don't quite line up correctly when building for JSCOnly, since JSCOnly doesn't seem to provide a BPlatform macro. I can take a look at this later today.

Please note that this (building JSCOnly as a static library on Darwin) isn't an officially supported config, so breakages like this may happen periodically. Our supported configs are covered by continuous bots so this shouldn't happen for those configs.

In essence so is build-jsc and build-jsc --jsc-only the same thing, I don't know much about build and build commands, but I'm just using the build commands described for fuzzying that fuzzilli needs specify

https://github.com/googleprojectzero/fuzzilli/blob/8bfb44b818041d3eb9f9258614c6785c1a582fc8/Targets/JavaScriptCore/fuzzbuild.sh#L20 

Lastly, so in reference. with MacOS don't use --jsc-only option as future commits for the main WebKit branch might break the building process?

`--jsc-only` does not mean "only build jsc".  JSCOnly is the name of a build configuration that is for linux.

> , but I'm just using the build

fuzzilli targets linux AFAIK.

As explained earlier, if you use --jsc-only for macOS, there's no guarantee it will work.  It's primarily a linux build configuration.

I guess that fuzzily doc does specifically say that the invocation is intended for Darwin.  However, that is only fuzzilli's choice to use the option.  It is not the WebKit project's position to support that.  Again, --jsc-only is not officially supported for macOS.

Yep I see the notion now, static builds and jsc-only ports aren't officially supported by Mac standards and can break easily for Mac in the future with commits.

yes I believe so,

"make: *** [debug] Error 65
bootywarrior@Bootys-MacBook-Air WebKit % git branch
* (HEAD detached at b9ccc0e90392)
  main
bootywarrior@Bootys-MacBook-Air WebKit % 
"

from my understanding when you pull from WebKit.git it automatically I set to main then the git checkout switches to the commit change version you specify, whether my understanding understanding/knowledge of how git and commits work is accurate or not is to be seen. but above I tanned git branch and it shows main and it sought to (head detached to commit listed.

@Ben Nham 
Seems like the bug report I opened 2 weeks ago that you fixed here:
https://bugs.webkit.org/show_bug.cgi?id=244751

was regressed or something due to this commit for this error,

Seems like @Mark Lam was right about the slightest change breaking --jsc-only on MacOS
