Variable set to NOTFOUND

[mrmurphy]

Hi there! I'm trying to install on CentOs 6 using the buildscripts.
I followed the instructions in the readme, and I end up having the configuration fail on pyside install with this error:

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
QT_PHONON_INCLUDE_DIR
   used as include directory in directory /home/murphyra/repos/BuildScripts/pyside/build/CMakeFiles/CMakeTmp

CMake Error: Internal CMake error, TryCompile configure of cmake failed
-- Checking for VideoCaptureDevice in phonon -- not found
CMake version greater than 2.8 necessary to run tests
-- QT_SRC_DIR variable not set or graphviz not found, apidoc generation targets disabled.
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
QT_PHONON_INCLUDE_DIR (ADVANCED)
   used as include directory in directory /home/murphyra/repos/BuildScripts/pyside/PySide/phonon

-- Configuring incomplete, errors occurred!

I've checked, and the directory /usr/include/phonon exists.
I even tried setting that env variable, but it has no effect on the error.

Even after scouring the interwebs, I can't find a fix to this. Any advice?

How have you installed Qt, and which version do you use?

[mrmurphy]

I have:
QT SDK Version 4.8.
I installed it from the offline installation binary downloaded from the QT website.

I did set the environment variable QT_SDK_HOME to where the sdk lives:
/home/murphyra/QtSDK

I was able to temporarily circumvent the issue by setting the variable myself in the cmake script to : /usr/includes/phonon
but I ended up with make errors after reaching 95% built in the pyside directory.

Did you also try installing Qt 4.8 via Homebrew? The Homebrew version of
installing it is more tested than using the Qt SDK, so before we start
trying other things, I'd like you to test it via Homebrew ("brew install
qt") and remove the QT_SDK_HOME from the environment.sh script.

Thanks,
Thomas

Hmm, I'd love to do that, but I'm only finding Homebrew for OS X. Am I missing something?
I'm running on CentOs 6. Is there a way that I should get Qt 4.8 through yum?
---- Edit ----
If I write the command:
yum install qt.x86_64

It tells me:
Package 1:qt-4.6.2-20.el6.x86_64 already installed and latest version

It seems that that is saying I have QT 4.6 installed. But I check the InstallationLog.txt file in the SDK directory, and I see lines like this:
addDownloadable "qt-4.8.0-desktop-gcc.7z"
Which make me think I have qt 4.8 installed.
Thanks for your patience!

Oh yeah, sorry - I somehow assume you run OS X. Of course, if you are
running CentOS, get it via yum or (if the packages are too hold) build
Qt 4.8 from source and install system-wide. You might be able to use the
Fedora dependencies script included in the BuildScripts.

HTH.

Okay, that's probably where I got the Qt that's installed. I ran the dependency scripts and all of them installed successfully. Do you think I'm confusing my system by having the SDK installed as well? Should I just start over and install fresh, without installing the SDK?
(I'm running CentOs on a virtual machine, so it wouldn't be too hard to nuke it and start over.)

Yes, if you can, starting over would be the easiest solution. Also, if
you don't have a specific reason for using CentOS, feel free to try
Ubuntu 11.10 and use the dependencies script for that. It definitely
works with 11.10 and the dependencies script without the Qt SDK.

HTH :)

[mrmurphy]

Okay, I'm starting over.
I'd love to use Ubuntu, but I need to distribute to machines running Redhat 5, so I'm trying to get as close as I can with the virtual machine so as to ease the distribution process.

I'll let you know how it goes. Thank you!

[mrmurphy]

Okay, I started over. I did not install the SDK at all, I'm running on CentOs 6.2.
I ran the dependencies install script, and everything installs just fine. After doing that, if I type:

yum -y install qt

It says that QT is already installed.

When I run the build_and_install script, I get the same problem as before:
QT_PHONON_INCLUDE_DIR set to NOTFOUND.

Any more ideas?

[thp]

Which version of Qt is installed? ("qmake -version" should tell you the Qt version)

[mrmurphy]

Okay, maybe that's the issue. When I try to run qmake, it says "command not found".
The same thing happened when I installed the SDK, however, so maybe I didn't have my path set up right before.
It appears that the install of qt from yum is not complete, then? Maybe it's just the qt development headers that were installed.

What do you suggest is the best way for me to get a complete setup of QT that will work with these PySide set up scripts?

[thp]

Search for "qt-devel" packages or similar. Make sure that all these are installed. Also, have a look if there are separate "-devel" packages for phonon and/or qmake. Make sure that the Qt version is at least 4.7 for best results (4.6 should also work, but it's the minimum, and won't include Qt Declarative). I'd assume that CentOS might have a really old version of Qt, but I'm not sure.

[mrmurphy]

Ok, great! I'll do some searching. Thank you!
