Hi.
You can try force disable sse2 there

openMVG/src/nonFree/sift/CMakeLists.txt

Line 10 in 085fbe4

if(NOT USE_SSE2)

Else since we also have our own sift implementation it could be fine to just deactivate all this code.

from openmvg.

Thank you Pierre! I've tried to disable / enable SSE2, the nonFree/sift never build. So I comment out this code, but got error further down from features_repeatability about missing vlsift.

[ 83%] Linking CXX executable ../../Darwin-x86_64-RELEASE/openMVG_sample_main_features_repeatability_dataset
ld: library not found for -lvlsift
collect2: error: ld returned 1 exit status
make[2]: *** [Darwin-x86_64-RELEASE/openMVG_sample_main_features_repeatability_dataset] Error 1
make[1]: *** [openMVG_Samples/features_repeatability/CMakeFiles/openMVG_sample_main_features_repeatability_dataset.dir/all] Error 2
make: *** [all] Error 2

Now that we disabled the nonFree/sift, Is there a way to link this script to a different sift library?

thanks

OpenMVG is having its own sift code in src/features. So you can remove the vlsift dependency there

from openmvg.

Found it. Now everything compiles well after I remove vlsift. Thanks!
