Thanks for the diagnostics. ld shows that the linker is not finding
libraries properly as you suspected. This is the openwr t platform.
Looks to use gcc. The Issue I'm having I believe really has to do with
the make file creation.
It suggests using rpath or rpath-link so I'm working to properly
integrate them into the Makefile.
I'll report progress when get this working.
Cheers
Derek
