#49423: Octave configure can't find Qt libraries in El Capitan ---------------------------------+-------------------------------- Reporter: hartman.jonathan2@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Keywords: | Port: ---------------------------------+-------------------------------- I've got Qt 4 installed via macports and most other ports that require it as a dependancy (including KDE) have no problem finding the Qt 4 libraries and successfully linking against them to build. However, when installing Octave, the +gui variant also requires Qt 4 as a dependancy and detects that it is installed but the gui won't build and Octave will install without the gui even if you use the +gui variant. Digging deeper, I found that the reason was that the problem occurs during the configure stage where Octave's configure script cannot find the the Qt libraries and thus disables the gui build, even though the configure of other applications do. The configure log contains the warning "WARNING: Qt libraries not found -- disabling GUI". I've attached the entire log -- Ticket URL: <https://trac.macports.org/ticket/49423> MacPorts <https://www.macports.org/> Ports system for OS X
