Question

我需要为1994年为UNIX编写的一些代码提供一个Windows可执行文件。我试图从cygwin环境做到这一点。 C ++标准从此时起改为标准库。

我尝试使用-std =和-traditional-cpp选项，但这些选项根本没有帮助我。我还发现-fno-for-scope和-fno-operator-names减少了错误数量。此外，输入/输出库也发生了显着变化。我也认为预定义（通过预处理器）宏也有可能从那时起改变。

库中的C代码（库/ linpack和库/食谱）可以使用以下方法编译：

gcc -c *.c

C ++代码更成问题。在../include中有标题，它们需要-DANSI来产生函数原型。它们未在标题中声明extern "C";它们正确地包含在C ++源目录的头文件中：

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

所以，编译A3dStream.C，我得到：

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

其他文件产生类似的错误集。

我在Windows XP下使用GCC 3.4.4在Cygwin上。

我不是C ++大师 - 尽管我公平地分享了软件考古学 - 但我认为你需要更新代码以使用C ++标准头文件，因为特别缺少strstream.h（所以，名义上，使用<strstream>代替），这意味着你将不得不处理std命名空间等。此代码在标准之前提前了5年，因此必须努力破解标准并不是不合理的。

祝你好运！

Answer 2

我可以想到两种可能性：AT＆amp; T同时提供UWIN（可能与Cygwin不同，以避免同样的麻烦）和old versions of CFront的源代码（可能是原始编译器）使用）。

嗯，还有第三种可能性，我认为这是建议的操作：编辑源代码并使其达到标准的最新状态。如果您打算对此代码进行任何进一步的开发，最好尽快咬紧牙关。

您仍然可以从GNU网站下载gcc 2.7.0的源代码。

您可以下载并制作旧版本的编译器。
