[Jack-Devel] New build of QJackCtl for Windows

by Kjetil Matheussen

Hi all, The build of qjackctl included with jackdmp for windows is getting really old. The biggest problem is that the default "startup time" is set too low, making it seem like "jack crashes". (I"ve got many complains that "jack crashes"). Another problem is that you manually have to append "-S" to the "Server Prefix". So here: https://github.com/kmatheussen/qjackctl ...I've cloned the official qjackctl repository, fixed these two problems, and added some files to make it straight forward to build qjackctl under mingw32. (Building is just running the "build_mingw32.sh" script) Windows binary: http://folk.uio.no/~ksvalast/qjackctl.zip Perhaps this build, or something similar, can be included in the next release of jack for windows?

[Jack-Devel] broken submodule references for jack1 on GitHub master

by Markus Seeber

After just checking out jack1 from GitHub and trying to initialize the git submodules for headers, example-clients and tools I received the following error: $ git submodule update --init fatal: reference is not a tree: e74323c535876abca9a2293bd2ca426a3b91ff8b fatal: reference is not a tree: a2536c8b348bbfb21ec53db901e7992d7ffef474 fatal: reference is not a tree: 8e140b72de0231d129c6006db969f1dba4f1486b Unable to checkout 'e74323c535876abca9a2293bd2ca426a3b91ff8b' in submodule path 'example-clients' Unable to checkout 'a2536c8b348bbfb21ec53db901e7992d7ffef474' in submodule path 'jack' Unable to checkout '8e140b72de0231d129c6006db969f1dba4f1486b' in submodule path 'tools' After checking the referenced submodules, I found that the referenced commits _do not exist_ in the tree of these 3 repositories. The last change to the submodules was: > commit c758cdf4f6e959b92683f2dba6ce8617ac4f0a83 > Date: Tue Feb 23 10:15:45 2016 -0500 Which introduced many changes. What happened here? Are there pending commits of these 3 repositorys that are not yet public or was there a rebase in these so that the history got rewritten? For the time being, I assume it is safe to assume that HEAD of master is a valid commit to check out? Best regards Markus

[Jack-Devel] Cannot access portbuffer memory from C++

by Frank Schäfer

Hello all, I have written a small oscillator application in C++ Fiddling with errors and producing output to see where I am brougt me to a question: I had only ``printf( "Processing ...\n" ); in my process callback. My program started to produce output the moment when ``jack_activate( client );'' is called. Isn't this a bit waste of CPU due to the fact that the process_audio callback copies plenty of data to a port which is not used yet? I'd expect to get output from this (nothing sounding yet) program at the moment when it calls ``jack_connect'' for now I have this in my oscillator constructor: ... code snippet ... make_wave(); jack_activate( client ); //FIXME: throw exception if an error with client activation //FIXME: this should be placed elsewhwere and replaced by: // jack_activate -> jack_connect for port connections // jack_deactivate for port disconnections // the process callback will be called for every activated client // even no port is connected consuming unnecesary CPU power } ... Is this intended behavior? I'll leave the workaround in the comments in my code snippet in place then. I am using JACK 1.9.10 on a Linux x86_64 machine # uname -a Linux frankies 3.13.0-79-lowlatency #123-Ubuntu SMP PREEMPT Cheers Frank

[Jack-Devel] Help for compiling jack2

by JoergSorge

Hi, is it possible to help me building jack2, also for not so technical users? Perhaps, it could then be possible, to help others and complete this page: http://jackaudio.org/faq/build_info.html At first, it’s importend to inform the user about necessary libs for building. In other projects, it's find e.g. in a README. But here, I cannot find it on the page above and also not in the git repo. What I know is: build-essential But what’s are the exact libs for this, not all libs are called like in the error-messages, or we need the dev-variants: Checking for program 'doxygen' : not found Checking for 'alsa' >= 1.0.18 : not found --alsa requires the package alsa >= 1.0.18, but it cannot be found. Checking for 'libffado' >= 1.999.17 : not found --firewire requires the package libffado >= 1.999.17, but it cannot be found. Checking for 'libfreebob' >= 1.0.0 : not found Checking for 'gtkIOStream' >= 1.4.0 : not found Checking for 'eigen3' >= 3.1.2 : not found Checking for 'portaudio-2.0' >= 19 : not found Checking for header windows.h : not found Checking for header mmsystem.h : no Checking for 'celt' >= 0.11.0 : not found Checking for 'celt' >= 0.8.0 : not found Checking for 'celt' >= 0.7.0 : not found Checking for 'celt' >= 0.5.0 : not found Checking for 'opus' >= 0.9.0 : not found Checking for header opus/opus_custom.h : not found Checking for 'samplerate' >= 0 : not found Checking for 'sndfile' >= 0 : not found Thanks, Jörg
