64-Bit

Linux 找不到存在的文件

  • June 11, 2012

我正在嘗試啟動並執行 Google 的 Dart 語言,但在執行 dart2js 時會出錯。我正在執行 Arch linux,並從 AUR安裝了dart-sdk 。一些相關的終端輸出如下。

% dart2js main.dart   
/usr/local/bin/dart2js: line 7: /usr/local/bin/dart: No such file or directory

% cat /usr/local/bin/dart2js
#!/bin/sh

可能是因為我執行的是 64 位作業系統而 dart 二進製文件是 32 位的嗎?

為了執行 ELF 二進制 linux 需要啟動一個程序來解碼 ELF、載入動態庫等。這個程序稱為程序解釋器。程序解釋器的名稱和完整路徑寫在 ELF 本身中

例如

$ file /usr/bin/cheese 
/usr/bin/cheese: ELF 32-bit LSB executable, Intel 80386

$ readelf -l /usr/bin/cheese  
Elf file type is EXEC (Executable file)
...
Program Headers:
...
INTERP         0x000154 0x08048154 0x08048154 0x00013 0x00013 R   0x1
 [Requesting program interpreter: /lib/ld-linux.so.2]
...

如果沒有找到 ELF 請求的程序解釋器,BASH 會收到文件未找到錯誤並報告“沒有這樣的文件或目錄”。

正如@poige 上面所說,您需要安裝執行 32 位應用程序的基本支持。
