Any thoughts?

@xiaowenhe I was aware about your problem, please don't reopen two same issues.

from tf_deformable_net.

@paulcx It might related to gcc version and certain flags. I will add some lines in make.sh and FAQ. Now if you want to fix it instantly, check this issue.

from tf_deformable_net.

@Zardinality I have tried both solutions but they don't work so far with same error.
g++ -std=c++11 -shared -D_GLIBCXX_USE_CXX11_ABI=0 -o roi_pooling.so roi_pooling_op.cc
roi_pooling_op.cu.o -I $TF_INC -fPIC -D GOOGLE_CUDA -lcudart -L $CUDA_HOME/lib64
or

g++ -std=c++11 -shared -D_GLIBCXX_USE_CXX11_ABI=1 -o roi_pooling.so roi_pooling_op.cc
roi_pooling_op.cu.o -I $TF_INC -fPIC -D GOOGLE_CUDA -lcudart -L $CUDA_HOME/lib64

Am I right about the solution?

from tf_deformable_net.

@paulcx Make sure you use the recompiled version. Or try removing the related flag maybe. Which version of g++ do you use?

from tf_deformable_net.

@Zardinality What do you mean by using the recomplied version?
g++ is 5.40

from tf_deformable_net.

@paulcx I mean manually remove original generated file such as .o and .so, then recompile it. Also, since you use g++5(which I didn't have chance to test), you should compile with -D_GLIBCXX_USE_CXX11_ABI=0.

from tf_deformable_net.

@paulcx Hi, have you worked out where the problem is? I have updated readme to include a workaround given by others in another issue, which solves the same problem.

from tf_deformable_net.

@Zardinality Not yet. The solution does not work for g++5.4 at least.

from tf_deformable_net.

@paulcx check out this , it solved a similar undefined symbol problem for me.
