估计哪里不太对，可以参考ci build里的情况来对比下环境

怎么跟这里报的问题一样的？
是不是rtt里面有用到linux内核里面的头文件了，所以linux可以编译通过？windows编译不过？

[supperthomas]

@mysterywolf struct _reent 这个定义在哪里定义的？

rt-thread/components/libc/posix/io/stdio/libc.c

Line 124 in 6648419

_GLOBAL_REENT->__sdidinit = 1;

__sdidinit 这个好像rtt里面没有定义。

[mysterywolf]

这句话一直就没有动过

[supperthomas]

arm-gnu-toolchain-12.3.rel1-x86_64-aarch64-none-elf
我感觉可能toolchain变了。

[mysterywolf]

有没有什么标志宏可以区分一下？

[FragrantRye]

可以理解为当前rtt不支持12.3.1的toolchain吗？如果是的话未来有计划支持吗？
PS： 试了一下gcc-arm-10.2的确是OK的

[supperthomas]

__sdidinit 

components/libc/posix/io/stdio/libc.c 这里用到的toolchain里面的一些变量__sdidinit ， 这个在之前的toolchain里面有定义，最新的可能去掉了。所以如果用到这个相关的代码并且用12.3.1 的toolchain就暂时不支持。如果知道如何修改，可以尝试PR。用toolchain宏版本号隔开。

mirror/newlib-cygwin@44b60f0 newlib在这个commit里删除掉了
