Build error: The smaller Qt is not enough for Mozc build?

[siketyan]

Description The official build guide for macOS says:

The following configure options build a smaller Qt for Mozc.

./configure -opensource -developer-build -platform macx-clang -release \
-nomake examples -nomake tests -nomake tools \
-no-cups -no-dbus -no-icu -no-opengl \
-no-sql-db2 -no-sql-ibase -no-sql-mysql -no-sql-oci -no-sql-odbc -no-sql-psql \
-no-sql-sqlite -no-sql-sqlite2 -no-sql-tds

I tried this with Qt 5.15.9 and it did not work.

ERROR: /Users/siketyan/.local/src/github.com/google/mozc/src/gui/about_dialog/BUILD.bazel:50:12: no such target '@qt_mac//:bin/uic': target 'bin/uic' not declared in package '' defined by /private/var/tmp/_bazel_siketyan/d8db3a1cfdeab86baed422122839e2eb/external/qt_mac/BUILD.bazel (Tip: use `query "@qt_mac//:*"` to see all the targets in that package) and referenced by '//gui/about_dialog:uic_about_dialog'
ERROR: Analysis of target '//:package' failed; build aborted: 

Probably it is needed to add something to this feature set?

I changed MOZC_QT_PATH to .../qt-everywhere-src-5.15.9/qtbase and it started working. Perhaps it is docs error or I missed something?

Thank you for spotting this. What you did is actually right. The doc isn't clear on what archive needs to be downloaded.

Actually Mozc requires only qtbase. For your case https://download.qt.io/official_releases/qt/5.15/5.15.9/submodules/qtbase-everywhere-opensource-src-5.15.9.tar.xz should be sufficient.

We are now working on updating the macOS build instruction.

Thank you for the doc fixes and the binary releases!
