Bug 224602 – MacCatalyst ANGLE is linked with @loader_path/../../../libANGLE-shared.dylib

• Component: ANGLE
• Status: RESOLVED FIXED

[Kimmo Kinnunen]

MacCatalyst ANGLE is linked with @loader_path/../../../libANGLE-shared.dylib 

The path may be wrong.
The use of @loader_path is probably wrong.
ld: warning: invalid -install_name (@loader_path/../../../libANGLE-shared.dylib) in dependent dylib (/Users/kkinnunen/Build/Debug-maccatalyst/libANGLE-shared.dylib). Dylibs/frameworks which might go in dyld shared cache cannot link with dylib that uses @rpath, @loader_path,

DYLIB_INSTALL_NAME_BASE is probably wrong when WK_ALTERNATE_FRAMEWORKS_DIR is used.

I'm planning to fix this this afternoon.

Note that there are important steps to take when updating ANGLE. See https://trac.webkit.org/wiki/UpdatingANGLE

Out of curiosity, in which this loader_path is correct?

[Alex Christensen]

The use of @loader_path is necessary when we use WK_RELOCATABLE_FRAMEWORKS because we need to be able to relocate them and have dyld still find the dylib relative to the framework.

When building project ANGLE:
INSTALL_PATH\=/System/Library/Frameworks/WebKit.framework/Versions/A/Frameworks/WebCore.framework/Versions/A/Frameworks
DYLIB_INSTALL_NAME_BASE\=/System/Library/Frameworks/WebKit.framework/Versions/A/Frameworks/WebCore.framework/Versions/A/Frameworks

When building project ANGLE_iosmac before this change:
INSTALL_PATH\=/System/iOSSupport//System/Library/PrivateFrameworks/WebCore.framework/Versions/A/Frameworks
DYLIB_INSTALL_NAME_BASE\=@loader_path/../../../

When building project ANGLE_iosmac after this change:
INSTALL_PATH\=/System/iOSSupport//System/Library/PrivateFrameworks/WebCore.framework/Versions/A/Frameworks
DYLIB_INSTALL_NAME_BASE\=/System/iOSSupport//System/Library/PrivateFrameworks/WebCore.framework/Versions/A/Frameworks

This leads me to believe this will fix the problem.

Looking at other projects, and even at the below line, we are using DYLIB_INSTALL_NAME_BASE for this case, not INSTALL_PATH.

There is probably no difference in practice, but let's use the same solution as elsewhere.

[Alex Christensen]

I verified that does the same thing so I'll do it.

I also verified that when using relocatable frameworks, DYLIB_INSTALL_NAME_BASE is @loader_path/../../../ so there *should* be no problem there.
