我从这个链接下载了 C++ libJSON：https://sourceforge.net/projects/libjson/ 如何使用他们提供的代码创建库？
我安装了 MinGW，将它添加到环境变量的路径中，然后 cd 到了我有 makefile 的目录，并尝试使用 mingw32-make.exe。 但我收到此错误：
我知道我需要添加参数，但我不知道要添加什么.. 你能帮忙吗？ 谢谢！
【问题讨论】：
mingw32-make 是您运行的唯一命令吗？之前没有其他内容（包括环境变量集）？
标签： windows makefile compiler-errors mingw libjson
我正在开发 v7.6.1（目前最新）。从[SourceForge]: ninja9578/libjson - libjson_7.6.1.zip下载。
一开始我以为是半小时的问题（makefile的小改动，因为Win的mkdir创建了嵌套dirs 默认情况下，并且不接受 -p 参数）。
为了清楚起见，我尝试从 Win 的 cmd 运行 MinGW 的 mingw32-make窗口（不涉及额外的包装器）。
所以，我开始插入（在makefile 中）条件命令（基于OS），但这还不够。原始 makefile 为适应这种情况而需要进行的更改，与收益相比似乎太大（使文件更难理解）：在一个很少有人关心的环境中工作，所以合乎逻辑解决方案是创建一个单独的 makefile（称为 Makefile.mak）
尽管如此，官方文档 ("${LIBJSON_SRC_DIR}/Documentation.pdf") 声明：
MinGW (Windows) - 支持，部分测试
我没有通过整个 .pdf 了解发生这种情况所需的条件是什么，但是（除了它不起作用 - 因此存在这个问题）看起来在 makefile 中，有些东西看起来不正确：
rm -f vs. del /Q /S）中 > 有资格使用
cd - 不会改变 环境（cwd），导致下一个命令失败），还有命令分隔符（;），不按预期工作我“转换”了 makefile，考虑到当前的 Nix (Lnx) 行为应该保留在 Win，而且我还发现了一些（语法）错误（所以，显然 Nix 版本也无法正常工作 - 库已经构建好了，但仅此而已）。修复了错误，然后想在官方网站上发布答案（以便曾经关注它的任何人都应该知道这些变化）。
看了一眼，发现最后一个动作来自180622（还有更多，大约在那个日期）。但仔细一看，最后的实际工作似乎是在 5 年前（2013）完成的，所以我不确定如果它被维护（也快速浏览GitHub，但没有找到它）。
不管怎样，我联系了作者，因为我没有权限开票（提交补丁），但没有得到回复，所以我开始了一个线程：[SourceForge]: ninja9578/libjson - Request for permissions to submit a patch。我会提交补丁（前提是权限会授予我）。
无论如何，这是 Win makefile（大部分是从原始文件复制而来）：

在构建库时，我遇到了一件你应该注意的奇怪事情。以下是我使用过的工具版本/环境：
其中 3 个效果很好，但对于 #3.，我得到了：
_internal/Source/JSONWorker.cpp:297:26: error: cast from 'const char*' to 'long int' loses precision [-fpermissive] JSON_ASSERT_SAFE(((long)end - (long)pos) > 4, JSON_TEXT("UTF will go out of bounds"), return JSON_TEXT('\0');); ^
我不知道为什么会发生这种情况（可能是 g++ 配置问题？），但为了解决它，您应该添加 -fpermissive 编译标志（按照错误消息的指示）到 #146 行中的 cxxflags_default 变量：
cxxflags_default = -O3 -ffast-math -fexpensive-optimizations -fpermissive -DNDEBUG
这是默认构建，如果您选择其他变体（debug、small），则必须修改相应的变量。
虽然问题中不需要，但我也发布了 Nix 部分的修复程序（这在某种程度上是相关的，因为我在处理这个答案时发现了它们）。
