I'm trying to compile an run a very basic program given below (test.cpp) which calls the OpenNI class. You can see the files and dirs they're in here. Sorry that some characters screws up a little bit in the browser's encoding. I'm using the linux command: tree, if you know a better command tell me and I will update it.
I'm following the guide here, see "GCC / GNU Make".
#include < stdio.h >
#include < OpenNI.h >
using namespace openni;
int
main ( void )
{
Status rc = OpenNI::initialize();
if (rc != STATUS_OK)
{
printf("\nInitialize failed\n%s\n", OpenNI::getExtendedError());
return 1;
}
printf("Hello, world!\n");
return 0;
}
Here is what I'm running in the command line to compile it (gcc 4.7.2):
gcc test.cpp -I../OpenNI-2.0.0/Include -L/home/evan/Code/OpenNi/Init -l OpenNI2 -o test
This works fine but when I run ./test I get the following error:
Initialize failed
DeviceDriver: library handle is invalid for file libOniFile.so
Couldn't understand file 'libOniFile.so' as a device driver
DeviceDriver: library handle is invalid for file libPS1080.so
Couldn't understand file 'libPS1080.so' as a device driver
Found no valid drivers in './OpenNI2/Drivers'
Thanks, any help would be much appreciated.
Instructions from your guide says, that
It is highly suggested to also add the "-Wl,-rpath ./" to your linkage command. Otherwise, the runtime linker will not find the libOpenNI.so file when you run your application. (default Linux behavior is to look for shared objects only in /lib and /usr/lib).
It seems you have exactly this problem -- it can not find some libraries. Try to add proper rpath (seems to be /home/evan/Code/OpenNi/Init/OpenNI2/Drivers in your case) to your compilation string.
