我已经设法在 cygwin 2.10.0(0.325/5/3) (Windows 7) 下编译 bspwm 平铺窗口管理器，与 Openbox、LXDE 或 fwvm 相比，性能相当糟糕。你能给我一些解决这个问题的想法吗？

有时我需要在 windows 下测试一些 linux bash 脚本和命令，我需要多个终端窗口。将它装箱在 bspwm 的一个窗口中会非常方便，并且允许我根据需要设置我的终端工作区。

症状：

• 通过 Shift + PgUp 或 PgDown 在终端（urxvt）中滚动时重绘速度较慢
• Terminator 快一点，但打字很慢。
• 节点切换、在桌面之间跳转等命令的执行延迟约为 300 毫秒（只是一个猜测）。这是相当小的，但它让工作流程感觉不愉快。

有些应用程序即使在 Openbox 或 Fvwm 下也需要时间才能启动，但 gui 响应速度很快，即使在运行大型 vim 文件等时，urxvt 也能快速启动。

首先这是我的 XWin 启动日志：

我正在尝试在 Cygwin 2.884 (Windows 7) 下编译 i3 版本 4.14.1。我已经通过 Cygwin 安装程序安装了所需的 libiconv 库，但是在运行 ./configure 时出现此错误：

configure: error: in `/home/msamec/Downloads/i3-4.14.1/x86_64-unknown cygwin':
configure: error: cannot find the required iconv_open() function despite trying 
to link with -liconv
See `config.log' for more details

有什么线索可以帮助它找到图书馆吗？

我曾尝试手动编译库 libiconv-1.13.1 但遇到了一些我不知道如何解决的错误：

libtool: link: /bin/gcc -shared  .libs/localcharset.o .libs/relocatable.o      -o .libs/cygcharset-1.dll -Wl,--enable-auto-image-base -Xlinker --out-implib -Xlinker .libs/libcharset.dll.a

我已经 grepped iconv_open() 函数名称并在 cygwin 文件夹中找到它

/usr/i686-pc-cygwin/sys-root/usr/include/iconv.h

并且也在 libiconv 文件夹中

/usr/include/iconv.h

但由于某种原因，配置脚本无法找到它。

这是我的config.log

这是我的 iconv.h https://gist.github.com/anonymous/0b117d1680954d591f989256b508bfc5

我检查了这个库文件 inconv.h 在 Ubuntu 上的位置。Unlinke 在 cygwin 中位于 /lib/ 中，而在 cygwin 中位于 /usr/include/ 中。尝试将库复制到该位置，但这也无济于事。我也能够在我的家庭 Windows 10 上重现该问题。
