Failure linking dlib python bindings (missing vtable) on Raspberry Pi #1387

Closed ramonpoca closed 6 years ago

ramonpoca commented 6 years ago

Expected Behavior

Successful linking of the bindings.

Current Behavior

Error when linking with several undefined references:

undefined reference to `vtable for dlib::mfp_kernel_1_base_class<0ul>::mp_impl_T<dlib::mfp_kernel_1_base_class<0ul>::mp_null<dlib::mfp_kernel_1_base_class<0ul>::dummy> >'

Steps to Reproduce

git clone https://github.com/davisking/dlib.git
cd dlib 
python setup.py install --yes USE_NEON_INSTRUCTIONS --clean

This seems to be a bug in the compiler. There might be a workaround, but I don't have a raspberry pi to test on so you will have to work this out yourself, or find someone to help. I would start by trying to compile the C++ example programs and see if any of them fail. Many other things use the code it's complaining about, so maybe you can get an error there as well.

ramonpoca commented 6 years ago

Yep, it's a compiler (linker) bug. I installed gcc 6.4.0 from raspbian-testing and it went like a charm.

techbehindthescenes commented 5 years ago

Hi @ramonpoca, I'm trying to install gcc 6.4.0 - where did you get it from and did you have to build it first? Thank you!

ramonpoca commented 5 years ago

I installed the testing raspbian repo.

pi@raspberrypi:~ $  cat /etc/apt/sources.list.d/testing.list
deb http://raspbian.raspberrypi.org/raspbian/ testing main contrib non-free rpi

pi@raspberrypi:~ $ cat /etc/apt/preferences.d/testing.pref
Package: *
Pin: release a=testing
Pin-Priority: 750

pi@raspberrypi:~ $ cat /etc/apt/preferences.d/stretch.pref
Package: *
Pin: release a=stretch
Pin-Priority: 900

But note that it might mess your install. Also, OpenBLAS seem to be messing around (got segfault when using face-recognition).

techbehindthescenes commented 5 years ago

Helpful, thanks @ramonpoca!!

Similar problem, solved after installing latest clang(7.0.0). Installing newer gcc should work as well, but I prefer clang ;)
