編譯舊的C++ unix應用程序在Windows中使用

Question

我需要一個Windows可執行文件，用於一些代碼，這是1994年爲UNIX編寫的。我試圖從cygwin環境中做到這一點。 C++標準也從這個時間和標準庫中改變了。

我試圖用-std = - 傳統和-CPP的選擇，但選擇沒有幫助我。我還發現-fno-for-scope和-fno-operator-names減少了錯誤數量。此外，輸入/輸出庫也發生了顯着變化。我也認爲，預定義宏（預處理器）也有可能從那時起改變。

在庫（庫/ LINPACK和庫/配方）C代碼使用編譯罰款：

gcc -c *.c 

的C++代碼是更成問題。在../include中有頭文件，他們需要-DANSI來生成函數原型。它們在頭文件中未被聲明爲extern "C";它們包含正確的C++源代碼目錄標題：

extern "C" { 
#include "linpack.h" 
} 

所以，編譯A3dStream.C，我得到：

$ g++ -DANSI -I../include -c A3dStream.C

其他文件產生的錯誤類似的套。

我在Windows XP下的Cygwin上使用GCC 3.4.4。

我不是一個C++大師 - 儘管我公平地分享了軟件考古學 - 但是在我看來，你需要更新代碼來使用C++標準頭文件，因爲缺少strstream.h （所以，名義上，使用<strstream>代替），這意味着你將不得不處理std命名空間等。此代碼將標準預先標記了5年，因此不得不很難將其更新到最新版本。

祝你好運！

我能想到的兩種可能性：AT &牛逼同時提供UWIN（可能是不同的夠多了Cygwin來避免同樣的麻煩）和old versions of CFront源（這可能是使用原始編譯器）。

嗯，還有第三種可能性，我認爲這是建議的行動：編輯源代碼，並把它最新的標準。如果您打算對此代碼進行進一步的開發，最好儘早咬住這顆子彈。

您仍然可以從GNU網站下載gcc 2.7.0的源代碼。

您可以下載並編譯舊版本的編譯器。
