我正在使用交叉musl编译器(相同版本)构建本机musl编译器(GCC 8.3.0),但出现此错误:
t
关于如何规避此事的任何想法?

我在此处应用了肌肉补丁:http://port70.net/~nsz/musl/gcc-8.2.0/
我已经在源目录中运行了此命令:
1.1.21
答案 0 :(得分:3)
所以我将继续假设#pragma poison calloc
在您的头文件中,而不是在系统头文件中。
推荐的一般解决方案:在使用#pragma poison
之前包括所有系统头文件;当有多个程序头时,这可能会很棘手,但这确实需要完成。
另一种选择是从源代码及其保护措施中删除#pragma poison
。
