Will you support the latest DBoW2?

[sunbingfengPI]

I found that the latest DBoW2 has removed DVision and Boost dependencies, but this DLoopDetector repo still depends on them.

Moreover, it compiled failed with the latest DBoW2.

The main reason about it is that FBrief::TDescriptor in the latest DBoW2 has been changed to std::bitset<L> from boost::dynamic_bitset<>.

Appreciate it if you could update it to the latest DBoW2.

Thanks!

It seems this issue solved the problem.

#15 (comment)

However, I couldn't solve it with this issue.

May I ask have you solved the problem?

I used the old DBOW2 library(commit id: 67edcbc16903b314e9f19fd0bce6e93eef5e6635) instead.

You could set the GIT_TAG to use the history commit to hack over it.

        ExternalProject_Add(${name}
          PREFIX ${DEPENDENCY_DIR}
          GIT_REPOSITORY http://github.com/dorian3d/${name}
          GIT_TAG ${tag}
          INSTALL_DIR ${DEPENDENCY_INSTALL_DIR}
          CMAKE_ARGS -DCMAKE_INSTALL_PREFIX=<INSTALL_DIR>
          DEPENDS ${dependency})      

Wish it may help.

Thanks a lot @sunbingfengPI . I solved the problem with your suggestions.

The modifications I made are as follows. I am using Ubuntu 14.04.

`
macro(GetDependency name other_dependency tag)
find_package(${name} QUIET
PATHS ${DEPENDENCY_INSTALL_DIR})
if(${${name}_FOUND})
message("${name} library found, using it from the system")
include_directories(${${name}_INCLUDE_DIRS})
add_custom_target(${name})
else(${${name}FOUND})
message("${name} library not found in the system, it will be downloaded on build")
option(DOWNLOAD${name}dependency "Download ${name} dependency" ON)
if(${DOWNLOAD${name}dependency})
ExternalProject_Add(${name}
PREFIX ${DEPENDENCY_DIR}
GIT_REPOSITORY http://github.com/dorian3d/${name}
# GIT_TAG master
GIT_TAG ${tag}
INSTALL_DIR ${DEPENDENCY_INSTALL_DIR}

DEPENDS ${other_dependency})
else()
message(SEND_ERROR "Please, activate DOWNLOAD${name}dependency option or download manually")
endif(${DOWNLOAD${name}_dependency})
endif(${${name}_FOUND})
endmacro(GetDependency)
