Build for Raspberry hangs at [16%] Build CXX object lib/cpp-sdk/src/CMakeFiles/utils.dir/utils/Config.cpp.o

[nddao]

I Tried to build self on Raspberry PI 3, but it hangs at line [16%] Build CXX object lib/cpp-sdk/src/CMakeFiles/utils.dir/utils/Config.cpp.o

Raspberry is frozen and clock stops working, but still can ping its IP. Tried to reboot, tc_clean.sh, and build again, but it always stops at this line. #39

A similar issue was raised as https://github.com/watson-intu/self/issues/33. Please try the followings and see what will happen.

1. Use the latest code. We've eliminated a large plugin which might cause CPU overhead while build process. You can check the version by the following command.

   $ git --no-pager log -1

   * Incorporate recent changes in self plugins including support for Pepper's tablet and fix for build break in PCL
   
   * Incorporate fix in plugins for issue #31
   
   *  Incorporate pull request #5 of self-plugins
   
   * Add change for pull request #7 from watson-intu/pcl_removed

2. Reduce the number of cores to be used while build process. Change the line 33 of script/builds.sh from

   qibuild $ACTION -c "$TC_NAME" -j 4

   to

   qibuild $ACTION -c "$TC_NAME" -j 2

   . Please consider -j 1 if -j 2 is not enough.

3. Put a heatsink on the CPU chip of your RaspberryPi as in the picture.

Thanks. After downloading the development build this morning and modifying build.sh to have qibuild $ACTION -c "$TC_NAME" -j 2, the compilation process went pass Config.cpp.o. but it fails at Crypt.cpp.o

After getting the changed Crypt.ccp (from https://github.com/watson-intu/cpp-sdk/pull/3/files/6fd2af755431f7767561462dc5b95c42dab041cd )

And follow the steps in https://github.com/watson-intu/self/issues/37 , I am able to compile it successfully. Note that compiling on Raspberry uses up 100% CPU resources at some points.

@nddao I'm glad to hear that you've successfully built Intu for RasPi, and I'm curious about how you handled link error which I mentioned in https://github.com/watson-intu/self/issues/37#issuecomment-338113521. Did you use new ABI by disabling use of "add_definitions(-D_GLIBCXX_USE_CXX11_ABI=0)" in self/CMakeLists.txt as described in the link above ?

Also I'd like to know which version of opencv-objdetect is installed on your environment. You can check it by the following command.

$ dpkg -l "libopencv-objdetect*"
Desired=Unknown/Install/Remove/Purge/Hold

First, the main reason that it seems to be hang when compiling Intu on Rasbery PI is the "qibuild $ACTION -c "$TC_NAME" -j 4". With this statement, the build process could produce up to 4 processes at a time, and each process, at some point, consumes 100% CPU and 25% memory. After running for about 18 hours, the build terminsted with error "c++: internal compiler error: Killed (program cc1plus)". So using ""qibuild $ACTION -c "$TC_NAME" -j 2" works ( at least for me).

Seconds, the steps in #37, are needed for now until those changes are applied to the official build. Here are steps that I changed in my Raspberry to have a successfully compilation of Intu. a) Getting the new Crypt.ccp (from https://github.com/watson-intu/cpp-sdk/pull/3/files/6fd2af755431f7767561462dc5b95c42dab041cd ) b) Add set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fsigned-char") set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fsigned-char") add_definitions(-D_GLIBCXX_USE_CXX11_ABI=0) to the ~/self/CMakeLists.txt( Note that I just want to built Intu on Raspberry) Then run scripts/build_raspi.sh

@nddao Thanks for posting. It is quite interesting for me because you are using old-ABI (-D_GLIBCXX_USE_CXX11_ABI=0) and opencv-objdump is v2.4.9.1, which is same as mine, and no linking error. In my case, the following like error occurs.

[ 70%] Linking CXX executable sdk/bin/self_instance
sdk/lib/libself.so: undefined reference to `cv::CascadeClassifier::load(std::string const&)'
collect2: error: ld returned 1 exit status

I think all issues were resolved. I also changed the number of compiler processes to two in script/build.sh for Raspi. The latest code is included in PR https://github.com/watson-intu/self/pull/39. Thanks for your help!
