Question

我需要这个项目的Windows可执行文件： https://github.com/ashkang/jcal

我尝试将所有.h和带有main的.c文件添加到Qt Creator中的单个控制台非qt C ++项目中，但它会发出很多错误，例如：\jdate\jdate.c:-1 error: undefined reference to jlocaltime_r'。

我还在项目中添加了jasctime_r.3这样的未知文件。

如何在Windows中编译此项目？

Answer 1

好吧，它确实有用，如果你使用它的GNU构建系统，但你做需要一些代码更改来解决Windows上缺少的功能。

localtime_r()和gmtime_r()可以替换为localtime_s()和gmtime_s()并且参数交换。
对于strptime()，您需要提供一个实施，如果您修复了#includes并添加了#define TM_YEAR_BASE 1900，则可以使用open source one。

将固定的strptime.c放在sources/libjalali目录中并应用以下补丁：

然后，获取msys2，启动它的shell并安装包：

pacman -S mingw32/mingw-w64-i686-gcc msys/autoconf msys/automake msys/libtool

这应该足够了。

现在，您可以使用sources目录中的以下命令来构建它：

autoreconf -i
./configure
make

如何为Windows构建jcal？
