Xargo不再活跃维护了，不如试试Cargo-xbuild

但是我在装cross时候，也是这个错误，而且在mac上都是OK的，在win10上才报的这个 对以下内容的回复：

大佬，详细错误信息已贴出来了，请看下，具体问题是啥呢？ 对以下内容的回复：

详细的错误信息如下： error: linking with gcc failed: exit code: 1 C:\Users\Administrator\AppData\Local\Temp\cargo-installTfUGP7\release\deps\libbacktrace_sys-1b6210eebaee5bcd.rlib(alloc.o):alloc.c:(.text$__rbt_backtrace_alloc+0x31): undefined reference to __errno' C:\Users\Administrator\AppData\Local\Temp\cargo-installTfUGP7\release\deps\libbacktrace_sys-1b6210eebaee5bcd.rlib(alloc.o):alloc.c:(.text$__rbt_backtrace_vector_grow+0xb1): undefined reference to__errno' C:\Users\Administrator\AppData\Local\Temp\cargo-installTfUGP7\release\deps\libbacktrace_sys-1b6210eebaee5bcd.rlib(alloc.o):alloc.c:(.text$__rbt_backtrace_vector_finish+0x51): undefined reference to __errno' C:\Users\Administrator\AppData\Local\Temp\cargo-installTfUGP7\release\deps\libbacktrace_sys-1b6210eebaee5bcd.rlib(alloc.o):alloc.c:(.text$__rbt_backtrace_vector_release+0x41): undefined reference to__errno' C:\Users\Administrator\AppData\Local\Temp\cargo-installTfUGP7\release\deps\libbacktrace_sys-1b6210eebaee5bcd.rlib(posix.o):posix.c:(.text$__rbt_backtrace_open+0x2f): undefined reference to __errno' C:\Users\Administrator\AppData\Local\Temp\cargo-installTfUGP7\release\deps\libbacktrace_sys-1b6210eebaee5bcd.rlib(posix.o):posix.c:(.text$__rbt_backtrace_open+0x39): more undefined references to__errno' follow

Xargo是为了编译libcore的,只适合那些官方没有分发二进制libstd的target,一般这种目标也不能用std,只能用core,因此应该标上!#[no_std]

说好的 md 格式呢。

另外，错误信息是不是少了一大截，不够详细，看不出来啥。
