Hi,
I am trying to compile OpenCV 2.4.6 with CUDA. The compilation passed fine, however I got very large opencv_gpu246.dll output file (around 300 MB). I left options regarding GPU architectures unchanged in Cmake GUI, i.e.:
CUDA_ARCH_BIN 1.1 1.2 1.3 2.0 2.1(2.0) 3.0, CUDA_ARCH_PTX 2.0 3.0
Even if I try to compile for only one architecture, e.g.:
CUDA_ARCH_BIN 3.0 , CUDA_ARCH_PTX <empty>
I get quite a large file (around 60 MB).
When I compare these sizes to pre-built dll which ships with OpenCV (less than 1MB), the difference is huge. Has anyone observed the same behavior and what may be the problem?
Thanks in advance!
