http://askubuntu.com – I'm trying to install PIKLAB IDE for Microchip PIC controllers programming but stucking at error message as below: -- Could NOT find Threads (missing: Threads_FOUND) CMake Error at /usr/share/kde4/apps/cmake/modules/FindQt4.cmake:420 (FILE): file Internal CMake error when trying to open file: /home/bnh/Downloads/piklab-0.16.2/CMakeFiles/CMakeTmpQmake/tmp.pro for writing. May anyone tell me how to fix? Thanks in advance! (HowTos)
