Undefined 将模块加载到目标时未定义的符号

我尝试使用loadModule函数将库加载到目标系统时出错

有些符号未定义

Undefined symbol: __divdi3 (binding 1 type 0)    
Undefined symbol: __floatdidf (binding 1 type 0)

但所有这些符号都可以在目标的符号表中找到

如果您有任何建议，我们将不胜感激。

可以从主机中的静态符号表中找到丢失的符号，但是当我尝试在目标shell中使用symFindByName搜索这些符号时，出现了一个错误。您使用哪种编译器？我在GNU上遇到了一些问题，它没有生成可加载的对象文件，因为它包含大量未定义的符号。切换到Diab编译器修复了我的问题…嗨，卢卡斯，我使用Diab-alos。我通过使用globe符号表而不是包含一些sysmbol的系统符号表修复了这个问题
