我已經成功C 地用SWIG. 我發布了該模塊并且可以正常安裝它，但是當我去構建它時undefined reference，生成的c檔案中包含的函式會出現大量錯誤。
我將生成的solib檔案放在我的系統lib目錄中，并將庫中的頭檔案放在我的系統include目錄中，但這并沒有解決問題。我猜我也需要一個用于包裝c檔案的頭檔案，以便解釋器知道so檔案中的內容，但鑒于SWIG沒有生成檔案，我不知道我是否遺漏了其他任何內容。我將嘗試撰寫自己的頭檔案以查看是否可以解決錯誤，但即使可以，那不應該是SWIG自動執行的操作嗎？
我的源檔案在下面

uj5u.com熱心網友回復：
原因是 Go 編譯器對庫一無所知librawgo.so。
將以下行放在C注釋的頂部librawgo.go：
#cgo LDFLAGS: -L<path/to/dir/with/librawgo.so> -lrawgo -lraw
該指令告訴編譯器將此行添加到聯結器標志。
抱歉，我不知道如何修改您的 CMake 和 SWIG 設定以自動生成此行。
