can't find trax lib

[andyhx]

hi,I am compiling the code,I rebuild my caffe using Cmake ,but now I am having these linking problems, I download from https://github.com/votchallenge/trax/ get trax to build trax libraries and linking it,but it did not help,Do I have to rebuild trax,linking to project? Has anyone succeeded building it ? Want help ,Thank you !

errors are like followings:

I actually did not integrate my tracker into the trax framework; instead I used the approach described here: http://www.votchallenge.net/howto/integration.html
which is integrated in test_tracker_vot.cpp

[andyhx]

thx,I solved it myself
here is my solution:
download trax https://github.com/votchallenge/trax/ and make it
adding this in the cmakelist
add_executable (test_tracker_vot src/test/test_tracker_vot.cpp)
target_link_libraries(${PROJECT_NAME} ${OpenCV_LIBS} ${Caffe_LIBRARIES})
#target_link_libraries(${PROJECT_NAME} /home/public/git/vot-toolkit/tracker/examples/native/static_cpp.so)
#LINK_LIBRARIES("/home/public/git/trax/build/libtrax.so")
target_link_libraries(${PROJECT_NAME} /home/public/git/trax/build/libtrax.so)
target_link_libraries (test_tracker_vot ${PROJECT_NAME})

[davheld]

Nice!

[ujsyehao]

@andyhx Can you upload the entire CMakelist, I don't know how to put these in the file?

[ujsyehao]

@davheld I don't know what andyhx says. #target_link_libraries(${PROJECT_NAME} /home/public/git/vot-toolkit/tracker/examples/native/static_cpp.so). I cannot find toolkit in my computer. So can you solve it ?

[VictoriaW1]

@ujsyehao I have just encountered this problem and solved it by following the steps of andyhx:

• First, download trax. Then from the trax directory, type:

mkdir build
cd build 
cmake ..
make

• Second, modify CMakeLists.txt of GOTURN around row 84:

# Note: If can't find trax, please download trax and build it, then uncomment the below line and set the path manually
target_link_libraries(${PROJECT_NAME} /home/victoria/open_source/GOTURN/src/native/trax/build/libtrax.so)

You should set your trax path. ^ ^
