Hi Alan,
I was not using cmake because there is no cmake posible on that embedded
machine. I wrote a makefile by myself and gave linkeroption for the paths of the
libraries. As you see the binary tries search at different places and fails -
until it
finds successfully at /usr/lib/...
This repeats for all needed libraries. It is nicky - but I don't think it is
critical. May
be that can be figured out - but that is my first makefile for this machine.
Luckily it finds all libraries at the end.
The binary is executed as root.
For Robert tells me something about missing permissions I took a look at some
permissions in /dev/usb and saw some of them are --r--r--r - no w! So I changed
this
permissions to -rw-rw-rw and the errors disappeared for these files. But you
see there
are much errors "Inappropriate ioctl for device" and many of them are still
present
and I can't see why.
df8oe, Andreas
