3.6 交叉编译器之GCC：编译得到的loongarch64-unknown-linux-gnu-gcc运行出错

[wenheping]

Anybodysuggestion？

前面的步骤都做了吗？

[wenheping]

都做了，区别是1)我使用的是binutils-2.39的下载版本，而不是使用git pull的版本。2)我使用的是fedora37

今天把系统换成fedora34，问题依然。

[sunhaiyong1978]

目标系统的glibc编译了吗？

[wenheping]

还没有，我现在做的是3.6，第一遍gcc，目标系统glibc是3.8.

[sunhaiyong1978]

你这些报错找不到的东西可都是glibc的……，第一编的gcc就是为了编译glibc。

[wenheping]

制作目标系统glibc在configure阶段出错：

查config.log，里面有这个提示：
loongarch64-unknown-linux-gnu-gcc: error: unrecognized command-line option '-mlarge-func-call'

[sunhaiyong1978]

-mlarge-func-call 参数去掉，已经不用了

[wenheping]

去掉-mlarge-func-call 是解决问题的关键，现在问题解决。

另外，这里BUILD_CC和CC的区别是什么？
