Linux下ld搜尋問題：ld: cannot find -l"XX"

標籤：http   io   os   ar   sp   檔案   on   問題   bs   

ld命令列工具（連結庫的一個工具）的搜尋路徑是-L指定的，庫名是-l指定的。

 

比如: ld -L[dir] -l[mylib] --verbose

以上我用可視化的方法顯示ld的搜尋路徑，其結果是居然在mylib，也就是庫檔案名稱中自動加入了首碼lib，導致找不到我的mylib，因為我的lib名字沒有加入lib的首碼。所以要把庫名改了，加上lib首碼。我操，ld這樣的設計目的是什嗎？加入首碼是為了減少衝突機率嗎？？？類似很多第三方庫的API也是有自己的首碼，比如openGL就有gl的首碼，就是為了減少衝突。
