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

2022-06-01 17:03:33 後端開發

前言

最近任務多、工期緊，沒有時間更新博客，就水一期吧，雖然是水，也不能太失水準，剛好最近作業中遇到一個 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，這樣可以避免復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，之前的代碼都作業正常，但我新增了一個介面后，卻怎么也編譯不過，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~

另外查資料的程序中，發現 bind 最多支持 9 個引數，超過就不行了，不過在我的場景里，只有 4 個引數，所以也不是這方面的問題，可以排除，

排查程序

為了簡化問題的排查程序，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; 
}

 這里使用了 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 太過復雜：

$ make
g++ -Wall -g -c bindemo.cpp -o bindemo.o -std=c++11
bindemo.cpp: In function ‘int main(int, char**)’:

                                     ^
make: *** [bindemo.o] Error 1

其實看了這個 demo，很多人都會懷疑一個問題——是不是多載的 create_task 出了問題呢？確實如此，其實我只要將另一個 create_task 的宣告注釋掉 (實作仍保留)，這個 demo 就可以編譯通過了，運行效果如下：

$ ./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，因為引數使用了參考型別，一開始懷疑是參考的鍋，直接使用指標，不行；然后懷疑是沒有為參考引數添加 boost::ref，也不行；最后直接把 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，于是增加了一個同名的函式多載，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多載的問題，

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，于是干脆將它重命名為 create_task_param，這樣再系結就沒有問題了，

后記

問題雖然解決了，但是 bind 為何對多載函式如此“無能為力”呢？按理說根據提供給 bind 的引數，再匹配多載函式的引數串列，應該可以挑選正確的多載版本，

不過換個角度思考，bind 支持占位符，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 有一個引數使用了占位符，這個引數將在呼叫時才傳遞，而 bind 需要在系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 型別的多載版本的話，bind 就迷糊了，畢竟他不知道后面用戶會給占位符傳遞什么型別的引數不是？所以我猜測為了避免類似的問題，c++ 干脆不讓 bind 支持多載函式，直接出錯了事，編譯期錯誤總比運行期錯誤好解決，你覺得呢？

當然，比較迷的是，這里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 會挑選多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，但是我實際測驗的情況是，無論將兩引數的版本放在前面還是后面，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~
