[BusyBox] can only execute from root directory

[Brendan J Simon]

I previously posted a message saying that I can't execute programs that 
are copied to tmpfs filesystem on /tmp.  This message is erroneous.  I 
found that I can not execute any executable that is not in the root 
directory.  Well not 100% true.  It seems that busybox (and symlinked 
friends) work OK from any directory but my apps do not.  I used readelf 
to try and find some differences.  It seems that the  requesting program 
interpreter is different.

My apps have: [Requesting program interpreter: lib/ld-uClibc.so.0]
Busybox has: [Requesting program interpreter: /lib/ld-uClibc.so.0]

Note the missing slash before "lib" which makes it an absolute path 
rather than a relative path.  I think this is the problem as the error 
message I get when trying to run my apps from somewhere other than / is 
"/usr/local/bin/myprog: No such file or directory"

I don't know why the / is missing.  It must have something to do with 
the install directory not being absolute when I built uClibc.
Any ideas ???

I can get around it with "-Wl,--dynamic-linker,/lib/ld-uClibc.so.0" but 
it shouldn't really be necessary.

Cheers,
Bendan Simon.
