Hello,
I am trying to install OpenCV on QNX 6.3. This OpenCV is for Linux
& all other POSIX Based systems. But when I use ‘make’ it gives
me error messages like ‘linux/foo.h’ not found and compilation exit.
Since there is no linux directory in QNX but is there any other
solution of this or Is it possible to install it on QNX 6.3.
Thanx in advance.

Are the a set of defines or macros in either the Makefile, or a
header file, that specify what SORT of Unix system it should be
on? Is there a configure script that might run and try to detect
this?

There was a configured script that run without any error. But when I
run make the error came in when it compiles some file like “foo.c”
and “linux/foo.h” is a header file included in “foo.c”
/configure --enable-shared (as mentioned in OpenCV docs)
make
and here is the exact error message.

Well, it sounds like it didn’t configure very well. I don’t know
enough about the configure scripts – but you may have to look at
what/how it configures and give some options to tell it that it
isn’t on a Linux system.
and here is the exact error message.
cvcap_v4l.cpp:98: linux/fs.h: No such file or directory
cvcap_v4l.cpp:99: linux/kernel.h: No such file or directory
And, of course, QNX isn’t going to have any linux type headers like
that.
Since it claims to be compatible with many/most Unix type systems,
it has got to have a way to configure it to NOT assume it is on a
Linux system. (Cause BSD type systems aren’t going to have the Linux
headers either.) I don’t know how to do that, though.

We have most of OpenCV working on QNX 6.21. You should be
able to get “cv” and “cvaux” to compile. The libraries
are reasonably portable.
But the video capture subsystem, which is where you’re
having problems, isn’t going to work on QNX. It’s tied
to Linux-specific I/O. We had to write our own FireWire
camera driver (which I’m willing to release under the GPL.)
Or you can buy Mindready’s product.
Nor is “highgui” going to run under Photon without
major work. It’s a graphics package.
But the libraries, which contain the difficult vision
algorithms, can be brought onto QNX without much trouble.
What are you trying to do?
Now that QNX NC is gone, you can’t get the developers of
open source packages to make their code work on QNX.
So you can’t expect standard open source code to work on QNX.

Well I actually needed OpenCV just for video capture & I even
don’t need highgui. I just need frames to process on the target
system. I was comfortable with OpenCV but Is there any other library
package which can do this work.

OpenCV doesn’t really do video capture; it just uses Linux or
Windows facilities that do, and then loads frames into its
internal data structure.
Here’s the manual page for our FireWire camera driver.

We would consider making this available under the GPL, but
can’t maintain it. It requires the Mindready LLA library.
(http://www.mindready.com/eng/embedded_software_1.asp)
which may not be available for QNX 6.3 yet.
