RE: [Dev-C++] Linker :: Under the hood.

<P><BR>"ld (and therefore gcc) is sensitive about the order in which libraries and object<BR>files are specied on the command line. If libfoo.so depends on libbar.so, you<BR>must specify libfoo.so first (as counterintuitive as this may be). The reason is<BR>that ld keeps track only of unresolved symbols as it links. If libfoo.so and<BR>libbar.so depend on each other, one of the libraries will have to be specified<BR>twice (for example, -lfoo -lbar -lfoo)." -Programming Linux Games , pg 33<BR></P></DIV>

<DIV></DIV>Hello all, 
<DIV></DIV>
<DIV></DIV>I am trying to understand how the linker goes about 
<DIV></DIV>doing its work. Say I have two linker options -lx and 
<DIV></DIV>-ly. If I pass them in the order -lx -ly the linker 
<DIV></DIV>seems to be doing its job fine. But if I pass -ly -lx 
<DIV></DIV>the linker spits hell a lot of undefined references at 
<DIV></DIV>me!! Can someone throw light on how the linker goes 
<DIV></DIV>about doing its work under the hood. Specifically, 
<DIV></DIV>what has the order got to do with it? 
<DIV></DIV>
