Drumstick is a C++ wrapper around the ALSA library sequencer interface using
Qt4 objects, idioms and style. ALSA sequencer provides software support for
MIDI technology on Linux. Complementary classes for SMF, WRK and OVE file
processing are also included. This library is used in KMetronome, KMidimon and
KMid2, and was formerly known as "aseqmm".
Changes:
* OVE file format support, contributed by Rui Fan
* Optional RealtimeKit support for MIDI input thread
* guiplayer simplified and optimized, with OVE format playback
* Build system fixes: using visibility=hidden if it is available,
exceptions, static build.

Thanks for making this update available. All your programs are very nice.
One issue I've had w/ drumstick, perhaps ever since I installed kmid
(*), is that when I "sudo make install", I end up with binaries that
don't work:
gnulem-301-.../drumstick-svn/build> /usr/local/bin/drumstick-testevents
/usr/local/bin/drumstick-testevents: error while loading shared
libraries: libdrumstick-alsa.so.0: cannot open shared object file: No
such file or directory
However, using the just built binary "in place" works fine:
gnulem-300-.../drumstick-svn/build> bin/drumstick-testevents

Note that the install places the following libs, which seem to be
successfully used by other dependent apps like kmetronome/kmidimon (it
complains during build if they're not installed). And yet drumstick
itself isn't seeing them:
lrwxrwxrwx 1 root root 22 2010-09-05 19:55 libdrumstick-alsa.so ->

PS: (*): Ever since installing kmid, I've been seeing this error, not
sure if it's related: /sbin/ldconfig: /usr/lib64/libkmidbackend.so.1
is not a symbolic link.
Yet they're there:

You may be experiencing issues related to RPATH. The build system has this
feature (that I use in my projects) to link executables to libraries including
the whole library path into each executable. This is very convenient when you
are developing libraries and test programs together, because it allows you to
test the programs in place without installing them and without worrying about
environment variables like "LD_LIBRARY_PATH". CMake creates a "make
install"
command that shall relink the executables dropping the rpaths, so in a
production environment the programs behave as usual. More about this, here:
http://www.vtk.org/Wiki/CMake_RPATH_handling
To test if a program has RPATHs, use a command like this:
$ ldd /usr/local/bin/drumstick-playsmf
linux-gate.so.1 => (0xffffe000)
libQtCore.so.4 => /usr/lib/libQtCore.so.4 (0xb7498000)
libasound.so.2 => /usr/lib/libasound.so.2 (0xb73bc000)
libdrumstick-alsa.so.0 => /usr/local/lib/libdrumstick-alsa.so.0
(0xb735e000)
libdrumstick-file.so.0 => /usr/local/lib/libdrumstick-file.so.0
(0xb730c000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb721b000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb71fd000)
libc.so.6 => /lib/libc.so.6 (0xb7092000)
[...]
The above output shows a program that is installed without RPATH. The same
command on a program in my development directory shows this:
$ ldd build/bin/drumstick-playsmf
linux-gate.so.1 => (0xffffe000)
libQtCore.so.4 => /usr/lib/libQtCore.so.4 (0xb7602000)
libasound.so.2 => /usr/lib/libasound.so.2 (0xb7526000)
libdrumstick-alsa.so.0 =>
/home/pedro/Projects/drumstick/build/lib/libdrumstick-alsa.so.0 (0xb74c8000)
libdrumstick-file.so.0 =>
/home/pedro/Projects/drumstick/build/lib/libdrumstick-file.so.0 (0xb7476000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7385000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb7367000)
libc.so.6 => /lib/libc.so.6 (0xb71fc000)
[...]
The distro's packaging process already takes care of all this. You can use
these features for your own convenience, but my advice is to clean your system
and install all the programs from the distro repositories, or install from
sources but use a recent cmake version and read the documentation about the
different options and features available. If you are unsure: uninstall the old
versions before compiling a new drumstick release, and uninstall the libraries
that are producing errors when running ldconfig.

Pedro

May be OT here, but:
I wonder what has happened to your OBS project, after I upgraded to openSUSE
11.3, i realized that you hadn't made a repo for it, but now i see that the
whole repo got emptied (except for rtkit under branches:/)?

I'm not a packager, and my OBS repository was never more than a little
experiment to find how friendly it is. I'm still using OBS sometimes for
testing builds, and there is a drumstick-0.5.0 RPM right now. But the fact is
that I don't want to assume the burden of maintaining the repo myself.
Sorry, you may want to ask for packages to the opensuse community, or maybe to
the packman maintainers:
