| # qmake configuration for the Raspberry Pi 4 (32-bit) using the Mesa V3D |
| # graphics stack. (not the Broadcom stack) |
| # |
| # This supports accelerated OpenGL both for X11 and DRM/KMS. Perhaps |
| # Wayland too. |
| # |
| # Tested with a sysroot created from Raspbian Buster and a gcc 7.4 |
| # toolchain from Linaro. |
| # |
| # Example configure command line, assuming installation to |
| # /usr/local/qt5pi on device and ~/rpi/qt5 on the host: |
| # |
| # ./configure -release -opengl es2 -device linux-rasp-pi4-v3d-g++ -device-option CROSS_COMPILE=~/rpi/gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- \ |
| # -sysroot ~/rpi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/rpi/qt5 -v |
| # |
| # Check the configure output carefully. EGLFS, EGLFS GBM, and EGL on X11 |
| # should all be 'yes'. Otherwise something is wrong. |
| # |
| # If getting linker errors like "undefined reference to `_dl_stack_flags'" check the |
| # symlinks in the sysroot, they were probably not adjusted |
| # correctly. F.ex. sysroot/usr/lib/arm-linux-gnueabihf/libpthread.so must point to |
| # sysroot/lib/arm-linux-gnueabihf/libpthread.so.0. If it is a broken link instead, bad |
| # things will happen. |
