How to set include path when compiling mythtv with Qt4.8.6?

Quakeboy02 · 05-02-2014, 07:14 PM

I've just downloaded Qt4.8.6 and installed it to Debian Squeeze in the default location "/usr/local/Trolltech/Qt-4.8.6". I'm trying to compile mythtv 0.27. The problem is that I don't know how to tell it to use the new Qt4 in /usr/local/Trolltech/Qt-4.8.6. Is it a matter of setting some environment variable? Do I need to set something in the config for mythtv? Or is there some option I needed to set when compiling and installing Qt4?

Specifically the problem is that when compiling external/qjson, it's using /usr/include/Qt4 instead of /usr/local/Trolltech/Qt-4.8.6/include. There is a file CMakeLists.txt that has the following line, but I don't know what to do with it, if this is the problem.

Code:

INCLUDE( ${QT_USE_FILE} )

Using the Qt that comes with Squeeze is not an option. Neither is using the mythtv available with Squeeze.

haw are you using qmake?
in the Makefile option or using the *.pro

see: " qmake --help"

or are you going to be using the QT Creator IDE

Hi John,

A lot of effort has flowed under the bridge since I created this thread. I think that the following just may have solved it. At least I get a clean configure and a clean compile. I had to run qmake (with the proper qmake) in each of the subdirectories, but I'm not sure whether that was due to earlier steps that corrupted things, or whether mythtv has a bug in their Makefile setup related to Qt4.

Start off by removing all vestiges of Qt4 from Squeeze. Then install Qt-4.8.6 (http://anychimirror101.mirrors.tds.n...c-4.8.6.tar.gz) using their instructions. Don't forget to configure the mysql plugin (./configure -plugin-sql-mysql).

Then create this file in the mythtv directory and run it; making any changes necessary for your local situation.

File configureit.sh

Code:

#!/bin/sh
./configure --qmake=/usr/local/Trolltech/Qt-4.8.6/bin/qmake --qmakespecs=/usr/local/Trolltech/Qt-4.8.6/mkspecs/linux-g++

Now to address the usual issues related to installing a new mythtv client.

Oops, I left out a couple of environment variables that are probably important, too. I don't know which one of these entries was the magic chicken, unfortunately.

Make changes as appropriate for your system:

Code:

QMAKE_INCDIR_QT=/usr/local/Trolltech/Qt-4.8.6/include
PATH=/usr/local/Trolltech/Qt-4.8.6/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
C_INCLUDE_PATH=/usr/local/Trolltech/Qt-4.8.6
CPLUS_INCLUDE_PATH=/usr/local/Trolltech/Qt-4.8.6

These were typed in manually, so I hope I don't have any typos.

NOTE:
As it turns out, these environment variables aren't needed to compile or run mythtv-0.27. Just use the configure stuff above.
