SDK 1.2 support on TX1 (jetpack 2.3.1)

[NotInControl]

Trying to build opencv example on Jetson TX1 running jetpack 2.3.1, simply pulling the github repo (which works on my Tegra TK1, running Jetpack 2.3.1 fails on TX1 (running same jetpack) with missing opencv lib). This is a vanilla machine, just flashed with jetpack, no other modifications. Any ideas?

Hi,

you need to call cmake with -DCUDA_USE_STATIC_CUDA_RUNTIME=false to avoid opencv linking error.

Best, OB.

Is there a way to add -DCUDA_USE_STATIC_CUDA_RUNTIME=false into the cmake file so we can only call cmake from the terminal instead of always passing it this argument?
