Hi, I just try to complile qjackctl 0.1.0 and I get some compilation errors : In file included from src/qjackctlMainForm.cpp:26: src/qjackctlMainForm.ui.h: In member function `void qjackctlMainForm::transportStart()': src/qjackctlMainForm.ui.h:1281: `jack_transport_start' undeclared (first use this function) src/qjackctlMainForm.ui.h:1281: (Each undeclared identifier is reported only once for each function it appears in.)

Does someone experiment these errors before ? I'm runing Mandrake 9.1, qjackctl 0.0.9a from thac's rpms works fine. Regards, Christophe
