Failure to compile in Nvidia TX2 (ARM) about maplab HOT 5 CLOSED

Hi, I manage to built on ARM, see #7 . But I didn't get this unable to guess system type. If you manage to go through this error, the diff I gave may help you, even if we don't exactly have the same target architecture.

You can maybe try to do what they say and download this config.guess and replace the one in your workspace.

I installed glogs on the TX1.
install (apt) libunwind-dev and libunwind8-dev. Then use this CMakeList.txt

cmake_minimum_required(VERSION 2.8.3)
project(glog_catkin)

find_package(catkin_simple REQUIRED)
catkin_simple()

include(ExternalProject)

file(MAKE_DIRECTORY ${CATKIN_DEVEL_PREFIX}/include)

set(VERSION 0.3.5)
ExternalProject_Add(glog_src
  #URL https://github.com/google/glog/archive/v${VERSION}.zip
  GIT_REPOSITORY https://github.com/google/glog.git
  UPDATE_COMMAND ""
#  PATCH_COMMAND patch -p0 < ${CMAKE_SOURCE_DIR}/fix-unused-typedef-warning.patch
  CONFIGURE_COMMAND cd ../glog_src/ && ./autogen.sh && \\
    ./configure --with-pic
    --with-gflags=${gflags_catkin_PREFIX}
    --prefix=${CATKIN_DEVEL_PREFIX}
  BUILD_COMMAND cd ../glog_src/ && make -j 8
  INSTALL_COMMAND cd ../glog_src/ && make install -j 8
)

cs_add_library(${PROJECT_NAME} src/dependency_tracker.cc)
add_dependencies(${PROJECT_NAME} glog_src)
target_link_libraries(${PROJECT_NAME} ${CATKIN_DEVEL_PREFIX}/lib/libglog${CMAKE_SHARED_LIBRARY_SUFFIX})

cs_install()

cs_export(INCLUDE_DIRS ${CATKIN_DEVEL_PREFIX}/include
  CFG_EXTRAS glog-extras.cmake)

This simply download the lastest version of glog. This new version needs a previous command (autogen.sh) before the .configure.
Also removes the patch.

Great! Thank you @bidbest . It worked with the new CMakeList.
Now It failed with the error: unrecognised command line option '-mssse3'. So I guess I will just need to implement @Alabate 's diff.
Thanks again.

@Changliu52 The pre-release-january branch in both the maplab and the maplab_dependencies repo adds build compatibility for ARM processors, see here: #7

from maplab.

I deleted all mssse3 definitions in all CMAKELIST.txt. and all the deps are built correctly.
but the brisk package does not support neon and arm does not support mssse3.
so you can't build maplab on arm.
for a developer, it is quite easy to fix this - by replacing brisk with OpenCV.
and then I think maplab can be run on an arm device.
On the other hand, the performance issue is quite big.
because the maplab does not build on CUDA.
it require quite a lot of work to make this work on CUDA smoothly.
