Mex和IT ++的編譯問題

Question

我在編譯It ++庫時遇到問題。 我已經正確安裝了它，並用一個沒有mex的簡單示例對其進行了測試。

混合it_mex_fkmigration.cpp -litpp

Answer 1

您需要告訴mex It ++庫位於何處。 使用-I選項指定包含路徑； 和-L選項指定庫搜索路徑。

mex it_mex_fkmigration.cpp -litpp -Ipath/to/it++/library -Lpath/to/libitpp

過去，我在使用-L選項時遇到了麻煩，不得不通過使用-l選項指定庫的整個路徑來解決此問題。

mex it_mex_fkmigration.cpp -lpath/to/libitpp/libitpp.a -Ipath/to/it++/library

文檔中列出了可以傳遞給mex其他選項（在“ Mex腳本開關”部分下）。

此外，有關這些錯誤的mxArray ， mexErrMsgTxt等表明您還沒有mex.h在it_mex_fkmigration.cpp
