Alternative to LD_PRELOAD

[arvind k]

Hi All,

I am looking for an alternative to LD_PRELOAD 
functionality. My application is "setuid root" and 
hence I can not use LD_PRELOAD. Is there any other 
way by which I can force preloading a shared library
(say liba.so) when I start the application? 

My application is already linked with another shared 
library (say libb.so). So can I combine libb.so with 
liba.so using ld or gcc, so that both library code 
gets loaded when the application is executed?

I tried the following. But it doesn't work. 

gcc -shared -Wl,-soname,libb1.so -o libb1.so.1.0.1 
-Wl,--whole-archive libb.so liba.so 
-Wl,--no-whole-archive -lc

Thanks in advance,
Arvind.
