已存放百度网盘, 下载 milkv-duo-tinycc.zip 后按照下面说明操作

1. 将 milkv-duo-tinycc.zip 通过ssh上传到开发板系统安装

scp ./milkv-duo-tinycc.zip root@192.168.42.1:~/

2. 安装TinyCC

ssh root@192.168.42.1
cd ~/
unzip milkv-duo-tinycc.zip
cd milkv-duo-tinycc
./install.sh
cd ..

3. 编写上传测试程序
将下面代码保存到本机 test.c 文件

#!/usr/local/bin/tcc -run

#include <stdio.h>

int main(int argc, char **argv){
    printf("%s---\n", "hello milk-v!");
    return 0;
}

scp ./test.c root@192.168.42.1:~/

4. 编译运行测试程序

cd ~/
tcc -o test test.c
./test

5. 解析执行测试程序

tcc -run test.c

6. 脚本执行测试程序

chmod +x test.c
./test.c

7. 附上测试程序包 tcc-examples.zip

scp ./tcc-examples.zip root@192.168.42.1:~/
cd ~/
unzip tcc-examples.zip
cd ./tcc-examples
./test.c

注意此版本需在musl编译的内核上执行

Hi.
Could you share the files on another host that is not Baidu?

Cheers.

Awesome, thanks a lot!!

Thank you. Is there any chance we can also have the tcc-examples.zip file shared here as well?

I had to “chmod +x intsall.sh” for it to install … and then also “chmod +x /usr/lib/bin/tcc” and then it compiled test.c and produced executable output.

Great to have a c-compiler on milk-v duo.

Thanks!

I’m not the original poster,so if u wanna share the examples.zip,maybe create a new post is better?

不好意思，之前的版本有点bug已更新，请重新下载安装。

你好，能否介绍一下具体是怎么编译的tinycc？ 我尝试去为milkv-duo编译tinycc，出现了报错，我是这样做的：
在配置好交叉编译工具链后，

git clone https://github.com/mirror/tinycc.git 
cd tinycc
./configure --prefix=$PWD/install   --cpu=riscv64

结果如下：

Binary directory    /mnt/d/MilkvDuo/XC/tinycc/install/bin
TinyCC directory    /mnt/d/MilkvDuo/XC/tinycc/install/lib/tcc
Library directory   /mnt/d/MilkvDuo/XC/tinycc/install/lib
Include directory   /mnt/d/MilkvDuo/XC/tinycc/install/include
Manual directory    /mnt/d/MilkvDuo/XC/tinycc/install/share/man
Info directory      /mnt/d/MilkvDuo/XC/tinycc/install/share/info
Doc directory       /mnt/d/MilkvDuo/XC/tinycc/install/share/doc
Source path         /mnt/d/MilkvDuo/XC/tinycc
C compiler          riscv64-unknown-linux-musl-gcc (.)
Target OS           Linux
CPU                 riscv64
Creating config.mak and config.h

然后执行make
出现了以下报错：

riscv64-unknown-linux-musl-gcc -DC2STR conftest.c -o c2str.exe && ./c2str.exe include/tccdefs.h tccdefs_.h
/bin/sh: 1: ./c2str.exe: Exec format error
Makefile:265: recipe for target 'tccdefs_.h' failed
make: *** [tccdefs_.h] Error 2

请问是我哪里做错了么？正确的做法应该是？
顺便提一句，我是在wsl环境下进行编译的，已交叉编译了redis，验证交叉工具链是配置正确的

  1. 保存编译脚本build_tcc.sh
#!/bin/bash
sdk_root=/media/yxw/milkv/duo-buildroot-sdk
export PATH=${sdk_root}/host-tools/gcc/riscv64-linux-musl-arm64/bin:$PATH
if [ -d ./install ] ; then
  echo "rm -rf ./install"
  rm -rf ./install
fi
if [ -f ./Makefile ]; then
  make clean
fi
./configure --prefix=$PWD/install --cpu=riscv64 --cross-prefix=riscv64-unknown-linux-musl- --triplet=riscv64-linux-gnu --enable-cross
gcc -DC2STR conftest.c -o c2str.exe && ./c2str.exe include/tccdefs.h tccdefs_.h
make cross-riscv64 riscv64-libtcc1-usegcc=yes && make install
  1. 执行脚本
    ./build_tcc.sh
