troube installing hydrogen

tw001_tw · 07-11-2004, 05:39 PM

Hello, I am trying to install hydrogen on my slackware 10.
(this is the file - hydrogen-0.8.2.tar.gz)

During ./configure I get no errors, but I get 2 warnings:

1-

Quote:

Perhaps you should add the directory containing `jack.pc'
to the PKG_CONFIG_PATH environment variable
No package 'jack' found
configure: WARNING: *** Could not find the JACK library, disabling JACK driver

2-

Quote:

checking lrdf.h usability... no
checking lrdf.h presence... no
checking for lrdf.h... no
checking for lrdf_init in -llrdf... no
configure: WARNING: *** Could not find the LRDF library

./configure ends with:

Quote:

-----------------------------------------------------------------
Hydrogen 0.8.2 configuration:
-----------------------------------------------------------------

Source code location: .
Prefix /usr/local
Images path /usr/local/share/hydrogen
Use ALSA Sequencer: yes
Debug messages: no
Jack support: no
OSS support: yes
LRDF support: no

Features list = (Alsa seq) (OSS)

-----------------------------------------------------------------
Now type make to build Hydrogen.
-----------------------------------------------------------------

So then I 'make'.

It all looks normal but at the end it says:

Quote:

AudioEngineInfoForm_UI.cpp: In constructor `
AudioEngineInfoForm_UI::AudioEngineInfoForm_UI(QWidget*, const char*,
unsigned int)':
AudioEngineInfoForm_UI.cpp:75: error: `Spacer2' undeclared (first use this
function)
AudioEngineInfoForm_UI.cpp:75: error: (Each undeclared identifier is reported
only once for each function it appears in.)
AudioEngineInfoForm_UI.cpp:80: error: `Spacer1' undeclared (first use this
function)
make[3]: *** [AudioEngineInfoForm_UI.o] Error 1
make[3]: Leaving directory `/root/installs/hydrogen-0.8.2/hydrogen_gui'
make[2]: *** [all-recursive] Error 1

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/installs/hydrogen-0.8.2'
make: *** [all] Error 2

So I have seen things like this before, and it works anyway, so I go and type make install:
At the end of 'make install' I get this:

Quote:

AudioEngineInfoForm_UI.cpp: In constructor `
AudioEngineInfoForm_UI::AudioEngineInfoForm_UI(QWidget*, const char*,

make[1]: *** [install-recursive] Error 1
make[1]: Leaving directory `/root/installs/hydrogen-0.8.2/hydrogen_gui'
make: *** [install-recursive] Error 1

So I try to type 'hydrogen' to start the program:

Quote:

bash: hydrogen: command not found

I am far from a programmer, and most of the things that scroll by during "./configure, make, make install" means nothing to me. I tried looking for hydrogen at linuxpackages.net, but its not there, so I got the source from hydrogen.sourceforge.net.

I should add, I did try to reference the LRDF error, and that package requiers raptor >= 0.9.11, which apparently I don't have, so I tried to get that.. I installed raptor-1.3.1 and raptor-devel-1.3.1. with pkgtool. Apparently that went fine. So I went back and tried installing LRDF again (liblrdf-0.3.7) and recieved similar errors doing a ./configure,make,make install as when I tried to install hydrogen (error 2 on 'make', and error 1 on 'make install'.).

At this point I am out of ideas. I understand I put a lot of info on this quesiton, but I tried to cover everything I could. Any one have a direction they could point me in??

Thanks in advance - tw.

Hi,
I downloaded and installed this package

it was a little pain but here is the fix :

tar xzvf hydrogen-xx.tar.gz
cd hydrogen-xx

from here edit :
hydrogen_gui/AudioEngineInfoForm_UI.h

and locate these lines near the top :

Code:

...
class QLabel;
class QPushButton;
...

Then add this line :

Code:

...
class QLabel;
class QPushButton;
class QSpacerItem;
...

And near the bottom :

Code:

protected:
...
QHBoxLayout* Layout9;
QHBoxLayout* Layout9_2;
...

add these lines :

Code:

protected:
...
QHBoxLayout* Layout9;
QHBoxLayout* Layout9_2;
QSpacerItem* Spacer2;
QSpacerItem* Spacer1;
...

Do exactly the same changes for the files :
hydrogen_gui/LadspaFXSelector_UI.h
hydrogen_gui/PreferencesDialog_UI.h

In fact it is not very difficult (need a little experience in c/c++), when I see an error like "Each undeclared identifier is reported...", the first thing I used to do is check what file cause the error and then look at the correspondant .h file, like for this one, there were no declaration for Spacer1 and Spacer2 and no declaration for the class QSpacerItem too.

I emailed the author and put a link to this thread, maybe the fix will be added in future version of hydrogen.

I was having the same problem and I followed your instructions and it worked. I will now start to look for this type of thing when compiling other software.

First rate help

Thanks a lot, keefaz
