fanquake 8837f1ebde Merge bitcoin/bitcoin#21654: build, qt: Make Qt rcc output always deterministic ... a58868d201 build: Makes rcc output always deterministic (Hennadii Stepanov) Pull request description: The Qt Resource Compiler ([rcc](https://doc.qt.io/qt-5/rcc.html)) has a command-line option `--format-version` which has the [default value](https://code.qt.io/cgit/qt/qtbase.git/tree/src/tools/rcc/main.cpp?h=5.12.10#n172) 2. The only difference from `--format-version 1` is adding a [last modified timestamp](https://code.qt.io/cgit/qt/qtbase.git/tree/src/tools/rcc/rcc.cpp?h=5.12.10#n207) to the output file ([credits](https://github.com/bitcoin/bitcoin/pull/21654#issuecomment-819198228) to **fanquake**). That, in turn, forces us to use `QT_RCC_SOURCE_DATE_OVERRIDE=1` to get deterministic builds (#13732). This change makes rcc output always deterministic by using `--format-version 1` option that makes usage of the `QT_RCC_SOURCE_DATE_OVERRIDE` needless. --- Also it improves interaction with ccache: On master (f6c44e999b): ``` $ make && make clean && ccache --zero-stats && make && ccache --show-stats ... cache directory /home/hebasto/.ccache primary config /home/hebasto/.ccache/ccache.conf secondary config (readonly) /etc/ccache.conf stats updated Sun Apr 11 15:45:43 2021 stats zeroed Sun Apr 11 15:45:05 2021 cache hit (direct) 638 cache hit (preprocessed) 0 cache miss 1 cache hit rate 99.84 % called for link 10 cleanups performed 0 files in cache 20023 cache size 13.2 GB max cache size 15.0 GB ``` The missed file is always `qt/libbitcoinqt_a-qrc_bitcoin_locale.o`.
