[Jack-Devel] Compiling jack2 in mixed mode

Hi there, I've been happily using the pre-installed Jack2 that comes with Ubuntu Studio 14.04.3. Now I require the ability to use more than 64 clients then tried to compile Jack2 from the package JACK 1.9.10 found at jackaudio.org/downloads I'm running on a 64 bits machine but would like to get support for 32 bits applications as well. Configure runs fine with ./waf configure --prefix=/usr --dbus --profile --mixed --clients=256 --ports-per-application=2048 --alsa --libdir=/usr/lib/x86_64-linux-gnu/ --libdir32=/usr/lib/i386-linux-gnu/ Then build fails: (...) /usr/bin/ld: cannot find -ldbus-1 (...) I know it has something to do with the 32 bits library of dbus but need help to find out how to get them properly. I have already the following installed: sudo apt-get install build-essential gcc-multilib g++-multilib fakeroot checkinstall sudo apt-get build-dep jackd2 sudo apt-get install libdbus-1-3:i386 Am I still missing some libraries? Is it about some environment variable? Is it necessary to compile libdbus? Thanks for your input. DjZU
