使用 gcc 鏈接兩個目標文件

Question

我想鏈接兩個目標文件，但是當我使用gcc -m32 file1.o file2.s -o output_file （我在某處讀到匯編文件不必編譯為對象）時，它會出錯：

我知道我顯然丟失了一些東西，但不知道從哪里獲取這些丟失的文件。 誰能幫我？ 非常感謝。

您似乎在 64 位機器上使用-m32 。 -m32是 -m32 用於編譯 32 位對象，當編譯器默認配置為編譯 64 位對象時。

發生錯誤是因為您沒有安裝 32 位版本的標准庫。

通過刪除-m32 ，要獲得gcc file1.o file2.s -o output_file ，您停止要求編譯將兩個 64 位對象鏈接為 32 位可執行文件，然后生成的可執行文件是 64 位（默認配置）。

但是，如果您真的想要 32 位，那么您應該使用-m32編譯您的對象。 您還需要確保您擁有相關的 32 位標准庫
