如何在 macOS 中編譯 librime-charcode

[markwu]

你好，請問如何在 macOS 中編譯 librime-charcode？看了 xcode.mk 內容，好像沒有定義。

[lotem]

參考 https://github.com/rime/librime/blob/master/README-mac.md
拆出這個插件主要是爲了避開在macOS上鏈接到本地ICU程序庫的問題。

我有看了，也都可以用 xcode/release-with-icu 編譯成功，並且編譯 squirrel 沒任何問題，但是就是不知道怎麼把 librime-charcode 加進來。

[lotem]

cd librime
git clone https://github.com/rime/librime-charcode.git plugins/charcode
make xcode/release-with-icu

[markwu]

好的，謝謝 @lotem，我馬上試試看。

出現錯誤訊息如下：

In file included from /Users/markwu/Temp/squirrel/librime/plugins/charcode/src/charcode_module.cc:6:
/Users/markwu/Temp/squirrel/librime/plugins/charcode/src/extended_charset_filter.h:21:44: error: only virtual member functions can be marked 'override'
  bool FilterCandidate(an<Candidate> cand) override;
                                           ^~~~~~~~

跟我之前用 ./install-plugin.sh rime/librime-charcode 後再 compile 的結果一樣。

PS. 我是用 homebrew 的 boost， version 1.72.0

[markwu]

我把

bool FilterCandidate(an<Candidate> cand) override;

改為

bool FilterCandidate(an<Candidate> cand);

也是不對。

我發現問題了，因為我從 rime/squirrel checkout 下來，rime/librime 還在舊的分支，所以整個編譯步驟要做如下修改：

$ git clone --recurse-submodules https://github.com/rime/squirrel.git
$ cd squirrel/librime
$ git checkout master
$ git clone https://github.com/rime/librime-charcode.git plugins/charcode
$ make xcode/thirdparty
$ make xcode/release-with-icu
$ cd ..
$ make

這樣，就可以成功編譯出包含有 rime/librime-charcode 的 squirrel 了。

最後就可以用 $ make install 來安裝 squirrel 了。

注意只能在本機安裝使用。
