Errors compiling on ARM (raspberry pi 3)

[rvdende]

Hey I have compile errors on raspberry pi. I had to mount an external usb flash drive as additional swap to actually get some progress during make.

I tried with and without git submodule update --init

This is the error I get with the ARM SSE2NEON code:

make Scanning dependencies of target dso [ 4%] Building CXX object CMakeFiles/dso.dir/src/FullSystem/FullSystem.cpp.o [ 8%] Building CXX object CMakeFiles/dso.dir/src/FullSystem/FullSystemOptimize.cpp.o [ 12%] Building CXX object CMakeFiles/dso.dir/src/FullSystem/FullSystemOptPoint.cpp.o [ 16%] Building CXX object CMakeFiles/dso.dir/src/FullSystem/FullSystemDebugStuff.cpp.o [ 20%] Building CXX object CMakeFiles/dso.dir/src/FullSystem/FullSystemMarginalize.cpp.o [ 24%] Building CXX object CMakeFiles/dso.dir/src/FullSystem/Residuals.cpp.o [ 28%] Building CXX object CMakeFiles/dso.dir/src/FullSystem/CoarseTracker.cpp.o In file included from /home/pi/Desktop/dso_arm/dso/thirdparty/sse2neon/SSE2NEON.h:123:0, from /home/pi/Desktop/dso_arm/dso/src/OptimizationBackend/MatrixAccumulators.h:29, from /home/pi/Desktop/dso_arm/dso/src/FullSystem/CoarseTracker.h:32, from /home/pi/Desktop/dso_arm/dso/src/FullSystem/CoarseTracker.cpp:32: /usr/lib/gcc/arm-linux-gnueabihf/6/include/arm_neon.h: In function ‘m128 _mm_set1_ps(float)’: /usr/lib/gcc/arm-linux-gnueabihf/6/include/arm_neon.h:5798:1: error: inlining failed in call to always_inline ‘float32x4_t vdupq_n_f32(float32_t)’: target specific option mismatch vdupq_n_f32 (float32_t a) ^~~ In file included from /home/pi/Desktop/dso_arm/dso/src/OptimizationBackend/MatrixAccumulators.h:29:0, from /home/pi/Desktop/dso_arm/dso/src/FullSystem/CoarseTracker.h:32, from /home/pi/Desktop/dso_arm/dso/src/FullSystem/CoarseTracker.cpp:32: /home/pi/Desktop/dso_arm/dso/thirdparty/sse2neon/SSE2NEON.h:155:4: note: called from here (x) ^ /home/pi/Desktop/dso_arm/dso/thirdparty/sse2neon/SSE2NEON.h:324:9: note: in expansion of macro ‘vreinterpretq_m128_f32’ return vreinterpretq_m128_f32(vdupq_n_f32(_w)); ^~~~~~ CMakeFiles/dso.dir/build.make:206: recipe for target 'CMakeFiles/dso.dir/src/FullSystem/CoarseTracker.cpp.o' failed make[2]: [CMakeFiles/dso.dir/src/FullSystem/CoarseTracker.cpp.o] Error 1 CMakeFiles/Makefile2:104: recipe for target 'CMakeFiles/dso.dir/all' failed make[1]: [CMakeFiles/dso.dir/all] Error 2 Makefile:83: recipe for target 'all' failed make: *** [all] Error 2

Has anyone managed to get past this error?

Oh I found a pull request, going to test it. https://github.com/JakobEngel/dso/pull/80

What's the frequency can it run on pi3? (how many images can calculate every second )

[MorganChabaud]

Well, this depends on so many variables...

To give you an idea, on 512x512, fast settings, an iteration (non-keyframe) takes 80ms (keyframe iteration around 150ms).

Did the pull request worked for you @fluentart ?

@chabaudmorgan I see, thank you very much!
