手臂动态链接

arm dynamic linking

本文关键字：链接 动态      更新时间：2023-10-16

我想在我的ARM项目中使用libftdi。我构建了libftdi，所有示例都可以正常工作。

程序： 

#include <stdio.h>
int main()
{
    printf("hello worldn");    
    return 0;
}

编译：

/usr/local/arm/4.3.4-armv4t-arm920t-eabi/usr/bin/arm-linux-gcc main.cpp -lftdi

跟踪输出：

我得到"分段错误"而不是在ARM上运行。

通过在目标本身的调试器中运行回溯、使用 remote-gdb 或通过收集可以在主机系统上分析的核心文件来收集回溯

。

我需要将标志-pthread添加到gcc参数

中
