Hello,

I have been  having an issue with one of my processes loading one of my libraries that was included in my binary image 
by mkifs with compression 3.

The included library is a different size as the one still in the compiled directory.  There were no errors on make or 
mkifs.

The problem I see is this:

# export DL_DEBUG=1
# export LD_LIBRARY_PATH=/proc/boot
# ls -la /proc/boot/liboamlib.so.1
-rwxrwxr-x  1 508       508          446464 Nov 13  2009 /proc/boot/liboamlib.so.1

Process 352276 (ls) exited status=0.

As you can see, the file in /tmp works much better than the one in /proc/boot.

I am cross compiling from x86 linux to ppc QNX 6.3.2.  Our build environment is not trivial to further complicate the 
issue.

Why are the libraries different sizes?
Could whatever changed the size of the lib cause this issue?
Is there anything else that could cause the issue?

Thanks,
Liam
