[gentoo-user] [OT] Still trying to compile hydrogen

[meino.cramer]

Hi,

I want to compile hydrogen cleanly.

Since the ebuild of hydrogen fails to compile because
the system "linux3" is not known (which happens even
when compiled on a linux-2.6*-booted machine)...

I was pointed to patch which fixes this problem, but
unfortunately it only opens the way to the next problem.

I decided to try to compile hydrogen from vanilla sources
and outside the emerge/portage system to better understand
wahts happening.

When doing so, one has to set QTDIR and then run scons.

Hydrogen needs qt4.

I set QTDIR to /usr/share/qt4.

The compilation fails because QtGui could not be found.

QtGui is here /usr/include/qt4/Qt/QtGui which is a file which 
includes all relevant header file in one go.

So I tried to set QTDIR to /usr/include/qt4 but this produces
the same problem.

I decided to hack the relevant file of hydorgen and hardcoded
the path to QtGui directly into the include statement. No comments
on this please, it is a bad bad ugly thing to do so. I simply
wa curious to see next problem...

And I was not dissappointed. This time the QtGui-file could not
find the first header file which it includes:

#include <QtCore/QtCore>

To hack also /usr/include/qt4/Qt/QtGui is no way.

So....either hydrogens build mechanism does not fit the installation 
of Qt4 on my Gentoo system (Qt4 was installed via emerge/portage) or
it has a bug or the problem sits right in front of my monitor and
is currently writing a post to the gentoo-users mailinglist... ;)

In the latter case the chance are not small, that I will be able to
fix the problem...

If I only would know, how ;))

What did I wrong here?

Thank you very much in advance for any help!

Best regards

You may want to try the ebuild again. I'm using kernel 3.2.6 on ~amd64
and just emerged media-sound/hydrogen-0.9.5 no problems at all.

Hi Paul,

As mentioned in my previous post, the problem is not the kernel
version and after getting over this bug there are others ahead.

How do I have to set QTDIR correctly under Gentoo/Qt4 ?

This is not related to your kernel version AFAICT. sys.platform is set to
linux2 on the two systems running version 3 kernels I've tried it on.
According to the python docs

"Changed in version 2.7.3: Since lots of code check for sys.platform ==
'linux2', and there is no essential change between Linux 2.x and 3.x,
sys.platform is always set to 'linux2', even on Linux 3.x. In Python 3.3
and later, the value will always be set to 'linux', so it is recommended
to always use the startswith idiom presented above."

It sounds like you are using an older python.

Sorry, I didn't see the other thread.

It's strange that it emerges normally for me, and the program works,
too. If there's any info about my setup that we can compare, please
ask me. :)

> How do I have to set QTDIR correctly under Gentoo/Qt4 ?

Because Qt4 is not segregated into its own directory like Qt3 was, I
would try setting QTDIR=/usr and see if it works. I have not tried
this myself.

Hi Neil,

QTDIR ist for Qt3 only, AFAIK Qt4 does not use it at all.

Right after reinstalling Qt-4.7 (core) and QtGui
emerging museseq it fails with

    This is the source of most people's problems when
    configuring muse.  If the configuration fails to find

    the directory where qt is installed.

This variable was necessary for Qt3, because that was often installed in
unusual locations like /usr/qt/3. Qt4 uses the normal hierarchy, with
stuff being installed in /usr/bn, /usr/lib, and so on. So this variable
should not be needed any more.

My guess would be that musesq uses Qt3 only, not Qt4.

Someone has the same problem here [*], and someone else came up with a
new ebuild for musesq-2.0_beta2. If that's newer than yours, give that a
try.

As this line in my previous posting states, museseq needs Qt 4.*,
which is installed...:

       configure: error: need qt >= 3.2.0

Um, huh? If it would need Qt 4.*, it would say that you need qt >=
4.something. But it says you need qt >= 3.2.0, so qt-meta 3.3.8b-r2
(which I have installed) would do fine.
Oh, I just see that this is no longer in portage, my qt-meta:3 comes from
the kde-sunset overlay.

Maybe having Qt4 installed with the qt3support USE flag would work, but I
doubt it. Qt4 is very different from Qt3.

my understanding is that qt3support gives run-time support only 
for apps built against qt3 but running under qt4 (i.e it's just a
simple run-time wrapper around API calls).

But qt3support cannot be used to built against qt4

So, if QT3 is removed from protage, and museseq which still is in
portage seems only to build agains qt3, I see a contradiction here...

May be on my system there somewhere leftovers from ancient time,
when qt3 needs some additional environment variables or such (?)...
what would it be...where I can I look for such settings?

But media-sound/museseq is NOT in the portage tree. If you have it,
then it comes from an overlay, or from a local ebuild that you maintain.

If museseq requires qt3, then the maintainer of the overlay (or you)
must provide qt3 or provide documentation about which overlay it is in.

IIRC you can find qt3 in kde-sunset

Either way it looks like a maintainer mistake

No, it has already been removed from portage two years ago [1], because it
still depends on Qt3. So your version probably comes from the proaudio
overlay.

What about trying the new ebuild for musesq-2.0 [2]?

Ooops! Sorry, I was mislead by some numbering "[1]" is used
for installs coming from pro-audio overlay and not "(1)" as I
thought.

Nonetheless, still wondering whats going on here...

Still investigating...

The mail at [2] is of 10.2011. If I am not totally wrong here I should
have the ebuild already on my system. I am doing updates regularily...

Well, but which version are you actually emerging?

I just added the pro-audio overlay to check for myself. emerge museseq
wants to build version 1.0.1. Which fails, aparrently it tries to write
to /usr/qt/3/etc/settings/ which is not allowed:

But with FEATURES="-sandbox -usersandbox" emerge museseq it builds fine.
1.9999 and 2.9999 seem to be written for Qt4, but subversion is unable to
check out the sources. Maybe this project is just dead?

But add kde-sunset to your overlays and emerge qt-meta:3, and it should
work.
