使用Git clone下载T-Head GCC Toolchain： <code>git clone git@github.com:bouffalolab/toolchain_gcc_t-head_linux.git</code> | |||
假设clone到了<code>/data/toolchain_gcc_t-head_linux</code>目录下： | |||
<syntaxhighlight lang="bash"> | |||
jenkins@debian:/data/toolchain_gcc_t-head_linux$ ls -l | |||
total 28 | |||
drwxr-xr-x 2 jenkins jenkins 4096 Dec 24 2022 bin | |||

drwxr-xr-x 7 jenkins jenkins 4096 Dec 24 2022 share | |||
</syntaxhighlight> | |||
然后把<code>/data/toolchain_gcc_t-head_linux/bin</code>路径加入到系统PATH环境变量中，假设你使用的是bash，则在<code>~/.bashrc</code>文件最后一行添加： | |||
<syntaxhighlight lang="bash"> | |||
... bashrc origin data ... | |||
# add t-head gcc toolchain to PATH | |||
export PATH=/data/toolchain_gcc_t-head_linux/bin:$PATH | |||
</syntaxhighlight> | |||
然后在当前终端下执行<code>source ~/.bashrc</code>使PATH环境变量生效，然后执行<code>riscv64-unknown-elf-gcc -v</code>应该可以看到GCC运行的打印。 | |||
