Bug 169067 – [Mac] WebCore.framework is missing a symlink from Frameworks to Versions/Current/Frameworks when the latter exists

• Component: WebCore Misc.
• Status: RESOLVED FIXED

When libwebrtc installs into WebCore’s Frameworks directory, there should be a symlink from Frameworks at the top level of the framework to Versions/Current/Frameworks. It makes sense for the WebCore target to create the symlink when needed (which, if I remember correctly, is iff WK_USE_OVERRIDE_FRAMEWORKS_DIR is NO).

I see WebKit has a Make Frameworks Symbolic Link build phase that this can mimic.

Should we be making libwebrtc's install path go to WebCore.frameworks/Versions/Current/Frameworks instead of to WebCore.frameworks/Frameworks which will now be a symlink?

libwebrtc’s own install path is, and should remain, …/WebCore.framework/Versions/A/Frameworks .

Ahh yes, sorry. iOS has shallow bundles, and we would only want to be adding the symlink for non-shallow bundle cases like macOS.

That’s why the bug title says [Mac] :|

The script is:

    if [[ ${PLATFORM_NAME} != "macosx" ]]; then
        exit 0
    fi

    if [[ ${WK_USE_OVERRIDE_FRAMEWORKS_DIR} == "YES" ]]; then
        exit 0
    fi

    ln -shf Versions/Current/Frameworks "$TARGET_BUILD_DIR/WebCore.framework/Frameworks"

This still creates a symlink in engineering Release/Debug builds, but I think thats harmless.

Creating the symlink in engineering builds seems fine. But you should not create it when ENABLE_WEB_RTC is empty.

This is now:

    if [[ ${PLATFORM_NAME} != "macosx" ]]; then
        exit 0
    fi

    if [[ ${WK_USE_OVERRIDE_FRAMEWORKS_DIR} == "YES" ]]; then
        exit 0
    fi

    # ENABLE_WEB_RTC cannot be relied on because of its conditionals.
    if [[ ${CONFIGURATION} == "Production" && ${TARGET_MAC_OS_X_VERSION_MAJOR} != "101300" ]]; then
        exit 0
    fi

    ln -shf Versions/Current/Frameworks "$TARGET_BUILD_DIR/WebCore.framework/Frameworks"

Someone might forget to update this when WebCore starts targeting newer macOS versions. Instead, I suggest that you use an inequality like
    ${TARGET_MAC_OS_X_VERSION_MAJOR} < 101300
.
