Hello Michael.
> Did you ever get set up to build from source?
>
I tried to prepare the build environment, following the procedure that I
found in the wiki of Rosegarden
http://www.rosegardenmusic.com/wiki/dev:contributing#prepare_the_build_environment
... and I downloaded the latest stable version of Rosegarden from wiki
... but when I run the
./configure
command I get the following error
configure: WARNING: Required JACK library not found, building with no
audio!
In the "build the environment" list from Rosegarden wiki is required
jack-audio-connection-kit-devel
in the opensuse environment I believe that the package is
libjack-devel
and this is installed.
Given that I know little about compilation from source I think I need
your help.
This list contains all the packages installed on my system that
"contain" the word "jack" in name or description field (taken from
OpenSUSe YAST package manager)

I also tried to look for other "jack" packages to be installed on the
OpenSUSE "Package Search" site, all that I find, however, is already in
the list available in YAST package manager.
Then I do not know what else to install.
I did a quick search on the web with the warning message that it
happened to me but I have not found anything that I have understood.
You think you can help me?

I did some check and test. (I have no idea if they are consistent)
a) speaking of png files I thought of a problem with some icon or
background image present in the active theme in gtk
change various gtk theme has not changed, however, the result
b) I verified that the version of libpng was updated
c) I tried to uninstall the current version of libpng, I was hoping to
try an older version, but too many programs use it, and will no longer
work

I apologize.
In this last two paragraphs I realized shortly.
I gladly collaborate with you, but I think you need a little patience.
Are still topics that I learn willingly, and I will try to force myself
to understand as much as possible.
