+# qmake configuration for Jetson TX1 boards running 64-bit Linux For Tegra
+# (tested with R24.2, sample root filesystem)
+#
+# Note that this environment has been tested with X11 only.
+#
+# A typical configure line might look like the following:
+#
+# configure \
+#   -device linux-jetson-tx1-g++ \
+#   -device-option CROSS_COMPILE=/opt/gcc-linaro-5.3.1-2016.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu- \
+#   -sysroot /opt/Linux_for_Tegra/rootfs
+#
+# Note that this builds for GLX + OpenGL. To use EGL + OpenGL ES instead, pass
+# -opengl es2 and ensure the rootfs has the headers (rootfs/usr/include/EGL,
+# GLES2, GLES3), which may not be the case out of the box.
+#
+# Check the configure output carefully, some features may be disabled due to the
+# rootfs not having the necessary dev files.
+#
+# If getting cryptic linker errors from static libs like libm.a, check that the
+# symlinks libm.so, libz.so, etc. under rootfs/usr/lib/aarch64-linux-gnu are not
+# broken. If they are, due to using absolute paths, change them so that they are
+# relative to rootfs.
