Question

我从以下链接下载了C ++ libJSON：https://sourceforge.net/projects/libjson/ 如何使用图书馆提供的代码创建图书馆？

我安装了MinGW，将其添加到环境变量的路径中，并使用cd到目录中，该目录中有makefile，并尝试使用mingw32-make.exe。但是我得到这个错误：

我知道我需要添加参数，但是我不知道要添加什么。你能帮忙吗？谢谢！

Answer 1

我正在研究 v 7.6.1 （目前是最新的）。已从[SourceForge]: ninja9578/libjson - libjson_7.6.1.zip下载。

起初，我认为这是一个半小时的问题（ makefile 中的微小变化，因为 Win 的 mkdir 创建了嵌套默认情况下为dirs，并且不接受 -p 参数。

为了弄清楚，我尝试从 Win 的 cmd 运行 MinGW 的 mingw32-make 窗口（不涉及其他包装器）。

因此，我开始插入（在 makefile 中）条件命令（基于 OS ），但这还不够。与获得的收益相比，原始的 makefile 所需的更改似乎太大了（使文件更难理解）：在一个很少有人在意的环境中工作，因此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” ）指出：

MinGW（Windows）-受支持，已部分测试

我没有浏览整个 .pdf 来了解发生此情况的必要条件，但是（除了它不起作用-因此存在此问题）看起来在 makefile 中，有些东西看起来不正确：

Shell（ Nix （ sh ， bash ，...） vs。 Win < / em>（批处理（ cmd ）， PS ， VBS ，...））命令（ GNU makefile ）差异（{rm -f vs。 del /Q /S）中被视为可用 / li>
makefile 命令的执行方式（每个命令 CreateProcess ：包括 cd -没有更改环境（ cwd ），导致下一个命令失败），命令分隔符（ ; ）也不会不能按预期工作
FS 路径分隔符（ / vs。 \ < / strong>）由上述命令处理

考虑到当前 Nix （ Lnx ）行为应保留在 Win 我“转换”了 makefile >，并且我还发现了一些（语法上的）错误（因此， Nix 版本显然也无法正常工作-很好地构建了库，仅此而已）。修复了错误，然后希望将答案发布在官方网站上（这样，使用它的任何人都应该知道更改）。

简短地看了看，发现最后一个动作来自 180622 （该日期前后还有更多）。但是当仔细观察时，似乎上一次实际工作是在 5 年前完成的（ 2013 ），所以我不确定如果已维护（也可以快速浏览GitHub，但找不到）。

无论如何，由于我没有打开票证（提交补丁）的权限，所以我联系了作者，但是没有得到任何答复，所以我开始了一个话题：[SourceForge]: ninja9578/libjson - Request for permissions to submit a patch。我将提交补丁（前提是将授予我权限）。

长话短说

无论如何，这是 Win makefile （主要是从原始文件复制过来的）：

步骤：

解压缩源存档（我将它们放在名为 libjson 的目录中）

在该目录中复制 Makefile.mak

从目录内部，调用（在 cmd 窗口中） mingw32-make 对此文件（mingw32-make -f Makefile.mak）

为了使一切正常运行， mingw32-make 的目录必须位于％PATH％（您已经知道）

如果您想要动态版本（ .so -实际上是一个 .dll ），则在调用 mingw32-make之前必须set SHARED=1

由于 mklink ， install 目标无法在较早的 Win 版本（例如 XP ）上运行

在构建库时，我遇到了一个奇怪的事情，您应该意识到。这是我工作过的工具版本/环境：

Win 上的
g ++ 5.3.0 - MinGW 的一部分（由 Qt 安装）
Lnx （ Ubtu ）上的
g ++ 5.4.0
Win 上的
g ++ 7.2.0 - MinGW 的一部分（由我构建）
Cygwin 上的
g ++ 7.3.0
其中的
3个很好，但是对于 ＃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？），但是为了解决这个问题，您应该添加 -fpermissive 将标志（按照错误消息的指示）编译到 ＃146 行中的 cxxflags_default 变量：

cxxflags_default = -O3 -ffast-math -fexpensive-optimizations -fpermissive -DNDEBUG

这是默认版本，如果您选择其他变体（调试，小），则必须修改相应的变量。

尽管这个问题不是必需的，但我还将发布 Nix 部分的修复程序（这些修复程序在某种程度上是相关的，因为我在研究此答案时已发现它们）。
