boost::bind 不能處理函式過載 (error: no matching function for call to 'bind')

前言
最近任務多、工期緊，沒有時間更新部落格，就水一期吧。雖然是水，也不能太失水準，剛好最近工作中遇到一個 boost::bind 的問題，花費了半天時間來定位解決，就說說它吧。
問題背景
專案中使用了 boost 的 ios_service，任務都是 post 到對應執行緒去執行，這樣可以避免複雜的多執行緒同步問題，有點類似早年間 COM 的單執行緒套間模型。不過這就需要將介面通過 bind 封裝為函式物件傳遞給 ios_service，之前的程式碼都工作正常，但我新增了一個介面後，卻怎麼也編譯不過，報下面的錯誤 (超長內容，展開謹慎)：

錯誤看著挺唬人，其實關鍵的就是第一句：
jni/../../Task/jni/../jni/../../xxxx/jni/../xxxx_xxxxxxxxx.cpp:3414:48: error: no matching function for call to 'bind'
xxxxxxxxxxx::instance()->getIOS().post(boost::bind(&xxxxxxxxxxxxx::create_task,
^~~~~~~~~~~boost::bind create_task 這個介面時出錯了，百度了下這個錯誤，網上比較多的說法是 bind 給的引數和介面宣告不一致，可是仔細檢查了三遍引數，都沒有發現問題，甚至把 post 改成直接呼叫的形式，這個就可以通過編譯，真是神了~
另外查資料的過程中，發現 bind 最多支援 9 個引數，超過就不行了。不過在我的場景裡，只有 4 個引數，所以也不是這方面的問題，可以排除。
排查過程
為了簡化問題的排查過程，排除其它因素干擾，我寫了一個簡單例子：
#include <iostream> #include <functional> using namespace std; int create_task(int); int create_task(int, int); int main(int argc, char* argv[]) { auto f1 = bind(create_task, 1, 2); f1(); return 0; } int create_task(int a) { cout << "create_task (" << a << ") called" << endl; return 0; } int create_task(int a, int b) { cout << "create_task (" << a << ", " << b << ") called" << endl; return 0; }
這裡使用了 std bind 而不是 boost bind，不過一樣可以復現出錯場景，同時避免引入 boost 靜態庫導致 demo 太過複雜：
$ make
g++ -Wall -g -c bindemo.cpp -o bindemo.o -std=c++11
bindemo.cpp: In function ‘int main(int, char**)’:
bindemo.cpp:11:37: error: no matching function for call to ‘bind(<unresolved overloaded function type>, int, int)’
auto f1 = bind(create_task, 1, 2);

make: *** [bindemo.o] Error 1其實看了這個 demo，很多人都會懷疑一個問題——是不是過載的 create_task 出了問題呢？確實如此，其實我只要將另一個 create_task 的宣告註釋掉 (實現仍保留)，這個 demo 就可以編譯通過了，執行效果如下：
$ ./bindemo
create_task (1, 2) called不過我在當初查這個問題的時候可是費了九牛二虎之力，因為引數使用了引用型別，一開始懷疑是引用的鍋，直接使用指標，不行；然後懷疑是沒有為引用引數新增 boost::ref，也不行；最後直接把 bind 介面改成另外一個成員函式 (start_task)，無意中居然通過了。不過此時我仍懷疑是引數的問題，於是增加了一個同名的函式過載，引數照抄 create_task，結果就失敗了；最神奇的是改為之前那版 start_task 也不行了，這才開始懷疑是函式過載的問題。
解決方案
知道了問題原因，改起來就比較順了，因為新版的 create_task 增加了一個結構體作為引數，於是乾脆將它重新命名為 create_task_param，這樣再繫結就沒有問題了。
後記
問題雖然解決了，但是 bind 為何對過載函式如此“無能為力”呢？按理說根據提供給 bind 的引數，再匹配過載函式的引數列表，應該可以挑選正確的過載版本。
不過換個角度思考，bind 支援佔位符，上面的例子中，我可以這樣寫：
int main(int argc, char* argv[])
{
auto f1 = bind(create_task, 1, 2);
f1();
auto f2 = bind(create_task, placeholders::_1, 0);
f2(3);
return 0;
}其中 f2 有一個引數使用了佔位符，這個引數將在呼叫時才傳遞，而 bind 需要在繫結那一刻知道使用的是哪個版本的 create_task，針對這個例子，他只有一個兩引數的版本可選，但如果有多個兩引數且第二引數為 int 型別的過載版本的話，bind 就迷糊了，畢竟他不知道後面使用者會給佔位符傳遞什麼型別的引數不是？所以我猜測為了避免類似的問題，c++ 乾脆不讓 bind 支援過載函式，直接出錯了事，編譯期錯誤總比執行期錯誤好解決，你覺得呢？
當然，比較迷的是，這裡只有一個兩引數的版本，bind 仍然報錯了，這是夠懶的。另外有些網上的文章說 (附錄 4)，bind 會挑選過載函式中第一個宣告的版本，如果通過就通過，如果不通過就報錯。但是我實際測試的情況是，無論將兩引數的版本放在前面還是後面，都報錯，除非不宣告，看起來我這個 gcc 版本是嚴格執行了 c++ 標準滴~
