Hello,

I'm planning on coming back to using Csound more after a Max/MSP period.
Long time since the last time I built Csound from source and I can see some
things have changed. Browsing the source I found a new installer directory
that contains scripts for Mac OS for building and packaging Csound. I'm not
sure if this would be the best way  to go about building and installing in
Mac OS, but I got it to work and generated a usable package. I did some
changes to the release-build-10.7.sh script in order to get STK and Loris
included but I came across a couple of problems that I would like to share
here.

First, I had trouble with the libpng library not getting detected and found
that the detection was failing because the Scons test for that library was
including "-framework CsoundLib" as a requirement, which obviously doesn't
exist yet. I fixed it by moving the section of the code that detects libpng
above the definition of the libCsoundLinkFlags variable in the SConstruct
file.

Second, my build works fine using csd files (and runs all the QuteCsound
examples) but I get a segmentation fault when trying to open orq/sco pairs,
with no other eror messages. I tried a few of these from the Csound Book CD
compilation and wasn't able to make them work (and on a related note, some
of the examples from that CD didn't work as csd either but due to syntax
errors in the score, I guess things have changed over time?). I tested using
the official 5.14 Mac OS package available on Sourceforge and the orq/sco
files worked fine so I wonder if this is related to the way I built it. For
example:

CoreMIDI real time MIDI plugin for Csound
PortMIDI real time MIDI plugin for Csound
PortAudio real-time audio module for Csound
virtual_keyboard real time MIDI plugin for Csound
0dBFS level = 32768.0
Csound version 5.14 (float samples) Nov 28 2011
libsndfile-1.0.25
orchname:  arpeggio.orc
graph init 
Error: define environment variable RAWWAVE_PATH
(points to rawwaves directory) to use STK opcodes.
rtaudio: PortAudio module enabled ... using callback interface
rtmidi: PortMIDI module enabled
orch compiler:
Csound tidy up: Segmentation fault


These are the flags I used for building: 

CC=gcc-4.2 CXX=g++-4.2 gcc4opt=universalX86 useFLTK=1 includeMP3=1 noDebug=1
buildInterfaces=1 buildStkOpcodes=1 buildPythonOpcodes=1 buildRelease=1
buildTclcsound=1 buildPDClass=1 useOSC=1 buildNewParser=1
dynamicCsoundLibrary=1 buildVirtual=1 useJack=1 buildCsoundAC=1 useGettext=0
buildBeats=1 NewParserDebug=0 buildPythonWrapper=1 buildMultiCore=1
buildJavaWrapper=1 buildLuaOpcodes=0 useDouble=1

Is the version on Sourceforge built with multicore and new parser? Could the
new parser be the cause?

Thanks!

Hector

Hi Hector,

Good to see you around again!  The orc/sco issue may be related to
some work that was done recently involving removing use of temp files.
 Are you using the latest from git?

As for the installer, it's the fully automated script Victor and I put
together.  It's somewhat customized for my Macbook Pro, so undoubtedly
changes would be required. For the scons changes, if you could send a
patch or commit that to git that'd be great.  I think next release I
may switch to using Cmake for the build though, but it's not certain
yet.

Thanks!
steven

Hello Steven,

Thanks for your reply. I was just about to create a patch and found that the
SConstruct file has been already fixed by someone else and has no issues
with detecting the png library.

Regarding the orc/sco problem, yes, I built from SVN (Nov 27). I'll rebuild
in a few days and check again. 

I was also wondering what the best practice would be for including the raw
wave files, required by the STK opcodes, in the final pkg installer. I
modified the release-build-10.7.sh script so it copied the raw waves into
the samples directory inside the Framework directories (for single and
double), together with the HRTF files. Would this be the appropriate place
where to put them? Do you have planned to include the STK opcodes in the
next official package release? I built the Loris opcodes too but I haven't
actually ever used them so I wonder if they are already superseded by newer
opcodes. Are both the STK and Loris not included in the official release due
to being already considered obsolete?

Cheers!

Hector

The reason Loris and STK aren't included is probably because they're
third party libraries. I guess libpng is standard on most OSes and so
is used by default.

tests so I wopuld like reports wih examples/outpurs please

Hi Steven,

I actually spoke too quick. I just did a SVN checkout and found the same png
detection problem, which again I fixed by modifying the SConstruct file. I'm
pasting the patch below (not sure if this list accepts attachments), in case
it's of any help. This change also fixed an error I was having when using
the release-build-10.7.sh script and the building of Opcodes/ampmidid.os
requiring -Framework CsoundLib when it didn't exist yet.

Cheers,

Hector

Hi John,

I just rebuilt from git and keep getting segmentation faults when trying to

Hi Hector,

Just following up on emails as I'm a little behind.  Was this ever
merged into Git?  If not, could you file a bug in the tracker so we
don't lose track?  (John and Victor have been very good about watching
and looking after items in the tracker)

Thanks!
