jevois-sdk full build failed

Question

Hello,

I try to rebuild all from scratch (not easy install) and i have the following errors :

when  executing this part :

# Configure kernel
	cd linux-3.4
	make mrproper
	cp config-jevois .config
	make xconfig # OPTIONAL -- do not mess with these settings unless you know what you are doing
	cp .config config-jevois # OPTIONAL: if you modified some configs

=>

velvet@velvet-ixtreme-M3720:~/jevois-sdk/linux-3.4$ make xconfig
  HOSTCC  scripts/basic/fixdep
  CHECK   qt
  HOSTCC  scripts/kconfig/conf.o
  SHIPPED scripts/kconfig/zconf.tab.c
  SHIPPED scripts/kconfig/zconf.lex.c
  SHIPPED scripts/kconfig/zconf.hash.c

 #error "This file was generated using the moc from 5.6.1. It"
  ^~~~~

And further when executing this part :

# fails on tbb compilation in waldboost:
	# there is a problem in tbb destroy_process_mask, just put an empty inline definition in tbb_misc.h
	emacs out/sun8iw5p1/linux/common/buildroot/build/opencv3-3.2.0/3rdparty/tbb/tbb44_20160128oss/src/tbb/tbb_misc.h
	./build.sh

=> 

i do

#if __TBB_USE_OS_AFFINITY_SYSCALL
  ...
    void destroy_process_mask();
#else
    ...
    //inline void destroy_process_mask(){} Is this the good fix ?

But I have always this error (when doing manually /jevois-sdk/out/sun8iw5p1/linux/common/buildroot/build/opencv3-3.2.0/make) : 

[ 62%] Linking CXX executable ../../../../bin/opencv_waldboost_detector

make[2]: *** [bin/opencv_waldboost_detector] Error 1

Any idea ?

Answer 1

Just skip the make xconfig in the kernel, unless you want to change some kernel configuration (most users should not). If you do want, then try a 'make clean' first. But I would recommend keeping that for later, after you get the whole thing to work with the base kernel. As we said: "do not mess with these settings unless you know what you are doing".

for TBB, yes, please see the latest INSTALL posted yesterday, it shows you what the destroy_process_mask() function should be for TBB to compile: indeed it is

inline void destroy_process_mask() { }

We are making a virtualbox with Ubuntu 17.04 now, taking a lot of time because ubuntu17.04 has failed to install on any of the Brix computers we have here. Bummer but slowly getting there on a virtualbox.

Answer 2

If you want to do a "make config" step, try "make gconfig" instead - you'll get the gnome-based gui instead of the qt one, and it works perfectly on the base ubuntu install.

As for the code changes, my fork has a commit which automates the patches; hopefully JeVois will include them soon.
