<rdar://problem/139602172>

I've met same problem?

Any solution to fix this? Or will it be fixed recently?

Currently, my workaround is using the "JavaScriptCore" scheme with xcodebuild command.

[Tim Chevalier]

I ran into the same problem. I did a `git bisect` and the problem seems to have been introduced in this commit:

https://lists.webkit.org/pipermail/webkit-changes/2024-July/304870.html

A partial fix is to edit `Source/bmalloc/CMakeLists.txt` as follows:

```
-- a/Source/bmalloc/CMakeLists.txt
+++ b/Source/bmalloc/CMakeLists.txt
@@ -722,7 +722,7 @@ WEBKIT_ADD_TARGET_CXX_FLAGS(bmalloc
 if (DEVELOPER_MODE AND (APPLE OR HAVE_MALLOC_TRIM))
     add_library(mbmalloc SHARED bmalloc/mbmalloc.cpp)

-    target_link_libraries(mbmalloc Threads::Threads bmalloc)
+    target_link_libraries(mbmalloc Threads::Threads bmalloc "-framework Foundation")
     set_target_properties(mbmalloc PROPERTIES COMPILE_DEFINITIONS "BUILDING_mbmalloc")
     WEBKIT_ADD_TARGET_CXX_FLAGS(mbmalloc -Wno-missing-field-initializers)
 endif ()
```

This works to get `libmbmalloc` building, but then the build fails in a later stage (linking `LLIntSettingsExtractor`), complaining about the same undefined symbols.

[Elliott Williams]

Definitely looks like https://bugs.webkit.org/show_bug.cgi?id=277383 added Foundation and objc code to bmalloc. In the Xcode-based build, we build bmalloc as a static library and link it into JavaScriptCore.framework, so its gets its Foundation and libobjc linkage from JavaScriptCore. So in the CMake build, where we build it as a dylib, we'll need to add the same linkage to targets below JSC.

As a workaround, I recommend using `Tools/Scripts/build-jsc` which uses Xcode to build, that's the configuration we actually defend in EWS.
