Hi,

I am using Momentix 6.4.0 tools. I have created a shared library libh264dec_lib.so, and linked to create an application 
called "h264dec". I have placed the library  in /tmp and updated LD_LIBRARY_PATH. I am still getting the error given 
below.
Any idea what is the issue?


export LD_LIBRARY_PATH=.:/proc/boot:/lib:/usr/lib:/lib/dll:/opt/lib:/tmp
# time ./h264dec BA_MW_D.264 out.yuv
Could not load library libh264dec_lib.so.1

Re: Shared library issue

Your so name does not match file name.

Now when you link against that library, program linker will 
  store dependency using soname (not filename), that is 
"libh264dec_lib.so.1". At runtime, ldd will read "NEEDED" 
from your executable (h264dec) and find 
"libh264dec_lib.so.1"; this will be used for file lookup.
