现象：在cmd下，通过xmake编译xmake通过的CUDA测试代码console，出现问题如下：
图片

从图中可以看出，编译到25%就退出来，也没提示任何的错误信息。

版本：
xmake：v2.6.2 HEAD.90e499cb2
操作系统：win7
vs ： vs2019

应该是吧 xmake 搞跪了，这种情况很少，之前只有一次低版本 vs 编译器的bug 吧 xmake 搞跪的情况出现。。

你可以先自己调下

xmake/xmake/modules/core/tools/nvcc.lua

Line 334 in edcbcd5

os.runv(program, argv, {envs = self:runenvs()})
这块，我暂时没环境复现。。回头有环境了，我再看看

系统的用户名绝对不能有中文，有中文的话如果系统某些语言选项设置不正确是无法编译成功cuda程序的

如果中文编码问题，那可能跟 vs 有关，因为 nvcc 会内部调用 cl.exe ，但是 cl.exe 对 unicode 的处理支持，需要一些特殊处理。。

可以在

xmake/xmake/modules/core/tools/nvcc.lua

Line 367 in 6654a88

local outdata, errdata = os.iorunv(program, argv, {envs = self:runenvs()})

这行，替换成 vstool.iorunv 调用，来尝试解决验证这个问题。

参考

xmake/xmake/modules/core/tools/cl.lua

Line 448 in 5ffe41d

return vstool.iorunv(program, argv, {envs = self:runenvs()})

并导入相关模块：

import("private.tools.vstool")
