strace观察时，可执行程序会多次加载动态库

Question

我已经针对uCLibc库和许多其他动态共享库在MIPS中构建了一个复杂的可执行程序。该程序运行良好，但是加载需要20秒钟以上，当我通过“ strace”观察到它时，我发现它一直在打开和关闭一些基本库，例如libm，libc，libgcc等。请查看以下日志：< / p>

fstat(3, {st_mode=S_IFREG|0755, st_size=477720, ...}) = 0
close(3)

我确信这种持续的打开和关闭操作会使我的程序变慢，我尝试在/ etc下创建ld.so.cache，但是它不起作用，它仍然需要20秒的加载时间。有人有主意吗？谢谢。
