我正在尝试使用scheme2c (DEC Scheme->C编译器)编译Scheme程序。这是程序hello.sc:
(module hello (main run-main))
(define (run-main)
(display "Hello!")
(newline))
我尝试使用scc hello.sc编译程序，但是编译失败，出现以下链接器错误消息:

如何使用scc编译Scheme程序
(scheme2c version 2012.10.14 on Ubuntu 20.04.4 LTS)
PIE在Ubuntu的GCC中是默认启用的(Ubuntu使用--enable-default-pie选项编译GCC)。
-no-pie选项来解决:
$ scc -cc 'gcc -no-pie' hello.sc
hello.sc:
$ ./a.out
Hello!
