运行hello_word遇到GLIBC_2.29 not defined in file libc.so.6改怎么办

[oiouou123]

如题，请问各位大佬，在D1运行hello_word看到

./hello_word: relocation error: ./hello_word: symbol __libc_start_main version GLIBC_2.29 not defined in file libc.so.6 with link time reference

这种情况该如何解决呢？

是不是用哪吒tina的SDK呢？如果用里面同一个gcc编译的话，libc.so.6 应该是 不会出这个错误提示的。

用编译rootfs的编译器编译

@tigger @YuzukiTsuru 大佬们，我用的官网提供的链接(如下说明)，下载下来是一个叫riscv64-linux-x86_64-20210329.tar.gz的工具

如果您只是想先试玩一下，还没下载完整源码，可以单独下载编译工具链：

riscv64-glibc-gcc-thead_20200702下载

另外我检查了开发板的Glibc版本发现就是2.29啊，看不懂了

@yuzukitsuru 大佬这个编译器是指那个，是官网那个吗链接，我下载拿到的是riscv64-linux-x86_64-20210329.tar.gz

[YuzukiTsuru]

@oiouou123 tina源码里的编译器，应该就是那个

@yuzukitsuru 谢谢大佬，直接装D1源码，用/tina-d1-h/prebuilt/gcc/linux-x86/riscv/toolchain-thead-glibc/riscv64-glibc-gcc-thead_20200702/bin底下的./riscv64-unknown-linux-gnu-gcc编译，可以看到结果
