Question

我已经从dhex_0.69.tar.gz下载了http://www.dettus.net/dhex/并解压了。自述文件只是说要运行make。

当我尝试在Windows 10上的MSYS2 shell中构建它时，编译和链接没有任何问题，我得到了.exe，它可以正常工作：

user@PC MSYS /d/src/dhex_0.69

但是，当在MSYS Shell之外运行时，此.exe将依赖于msys-ncursesw6.dll和msys-2.0.dll（因此，在命令提示符cmd.exe中运行时，确实会错误-或在Power Shell中，它不会引发错误；程序只是在那里退出）。

因此，我想尝试在MINGW64中进行构建。编译完成，但有警告-由于undefined reference to '_impure_ptr'，链接失败：

为了在MINGW64下编译dhex（所以它不再依赖MSYS dll了），有人知道我需要做什么吗？

Answer 1

我下载了该软件包，并弄清楚了如何使用MSYS2提供的MinGW-w64 64位工具链进行编译。

首先，安装相关的开发工具和库：

options['continuation']

接下来，您需要编辑软件包随附的Makefile。 LDFLAGS，CPPFLAGS和CFLAGS值必须修改为以下值：

'x-ms-continuation'

一些解释：Makefile在LDFLAGS和CPPFLAGS中具有硬编码的路径是非常糟糕的，因为如果要使用这些路径，则将使用来自另一个工具链（基于msys-2.0.dll的工具链）中的文件。因此，我们需要摆脱这些。另外，要摆脱有关printf格式的所有警告，我们必须提供pacman -S base-devel mingw-w64-x86_64-{ncurses,toolchain}参数。

然后，只需运行LDFLAGS= CPPFLAGS= -I$(MINGW_PREFIX)/include/ncurses CFLAGS= -D__USE_MINGW_ANSI_STDIO=1 -O3 -Wall。

在MINGW64下编译dhex？
