在 cygwin 中编译 linux C 程序时遇到问题
Trouble compiling linux C program in cygwin
我正在尝试在 Cygwin 中为 linux 编译一个名为 minimodem 的程序，因为我希望能够在 windows 中 运行 它。这是一个简单的命令行程序，我安装了 Cygwin，基本上包含了编译它所需的所有库。
一些库是：所有的音频，视频，数学，编译，开发，api，安装了系统和基础。
我 运行 遇到的第一个问题是 ./configure。从github中项目的源代码来看，没有配置文件或文件夹。我决定放弃它，而是直接使用 make 并引用文件夹中的所有文件。
首先发生的是这个错误：
minimodem.c: In function ‘main’: minimodem.c:556:4: error: #error At
least one of {USE_PULSEAUDIO,USE_ALSA,USE_SNDFILE} must be enabled! #
error At least one of {USE_PULSEAUDIO,USE_ALSA,USE_SNDFILE} must be
enabled!
^~~~~
所以我进入代码并删除了检查音频驱动程序的部分（即使 Cygwin 有所有可用的音频库）我再次尝试：
gcc -o minimodem.c
然后编译器走得更远了一点
然后给出了这个错误：

此时我不知道该怎么做，因为它在 Linux 上编译得很好并且 运行s 但使用 Cygwin 在 windows 上编译它可以做到这一点。如果有人知道我做错了什么或者我如何修复命令或文件以使其正常工作，谢谢。
正如@Sami Kuhmonen 在对您的问题的评论中所述：
Not all code can be compiled on different systems. If the code
requires a specific audio system, it might not be available
在这种情况下，它尝试使用三个库但在以下位置失败：
- PulseAudio : POSIX 操作系统的声音系统 (不是 windows, 然而: 已经在 Windows 2000 和 Windows XP 上测试过) 所以windows 在我看来，支持充其量是非常有限的
- ALSA : 它的名称中声明了 Advanced Linux Sound Architecture（可能不是 windows 对吧？）这是 Linux 用于与声卡驱动程序通信的特定代码在 Linux 个平台上。
- libsndfile : 它在网站上说它已经为 Win32 和 Win64 操作系统预编译了二进制文件，但它看起来不像最初设计时考虑了 windows
总而言之，像这样的音频代码可能试图与专为基于 Linux 的系统 (Linux vs Windows Audio in 2017) 设计的特定驱动程序进行通信。尽管 C 可以跨不同的操作系统移植，但在您编译程序所用的库中编写的代码很可能不是。
我很确定您必须编辑（移植）源代码才能处理更相关的 windows 音频编程。
注：
感谢@matzeri 的评论，Cygwin 上实际上有一个 libsndfile 包。见 link here.

然后我想也许我需要列出每个文件：
gcc -o baudot.c baudot.h databits.h databits_ascii.c databits_baudot.c databits_binary.c databits_callerid.c databits_uic.c fsk.c fsk.h minimodem.c simpleaudio.c simpleaudio.h simpleaudio_internal.h simpleaudio-alsa.c simpleaudio-benchmark.c simpleaudio-pulse.c simpleaudio-sndfile.c simple-tone-generator.c uic_codes.c uic_codes.h
但这带来了很多不同的错误：

此时我不知道该怎么做，因为它在 Linux 上编译得很好并且 运行s 但使用 Cygwin 在 windows 上编译它可以做到这一点。如果有人知道我做错了什么或者我如何修复命令或文件以使其正常工作，谢谢。
正如@Sami Kuhmonen 在对您的问题的评论中所述：
Not all code can be compiled on different systems. If the code requires a specific audio system, it might not be available
在这种情况下，它尝试使用三个库但在以下位置失败：
- PulseAudio : POSIX 操作系统的声音系统 (不是 windows, 然而: 已经在 Windows 2000 和 Windows XP 上测试过) 所以windows 在我看来，支持充其量是非常有限的
- ALSA : 它的名称中声明了 Advanced Linux Sound Architecture（可能不是 windows 对吧？）这是 Linux 用于与声卡驱动程序通信的特定代码在 Linux 个平台上。
- libsndfile : 它在网站上说它已经为 Win32 和 Win64 操作系统预编译了二进制文件，但它看起来不像最初设计时考虑了 windows
总而言之，像这样的音频代码可能试图与专为基于 Linux 的系统 (Linux vs Windows Audio in 2017) 设计的特定驱动程序进行通信。尽管 C 可以跨不同的操作系统移植，但在您编译程序所用的库中编写的代码很可能不是。
我很确定您必须编辑（移植）源代码才能处理更相关的 windows 音频编程。
注：
感谢@matzeri 的评论，Cygwin 上实际上有一个 libsndfile 包。见 link here.
