1.compile CpuCompute_wrap.cxx, generate py file
swig -python -c++ -I/home/hanyu/Documents/kaldi/src -I/home/hanyu/Documents/kaldi/tools/ATLAS/include -I/home/hanyu/Documents/kaldi/tools/openfst/include -DHAVE_CXXABI_H -DHAVE_ATLAS -DKALDI_DOUBLEPRECISION=0 -DHAVE_EXECINFO_H=1 CpuCompute.i
2.compile .o file for preparing so lib
g++ -std=c++11 -I/usr/include/python2.7 -I/home/hanyu/Documents/kaldi/src -I/home/hanyu/Documents/kaldi/tools/openfst/include -Wall -Wno-sign-compare -Wno-unused-local-typedefs -Wno-deprecated-declarations -Winit-self -DKALDI_DOUBLEPRECISION=0 -DHAVE_EXECINFO_H=1 -DHAVE_CXXABI_H -DHAVE_ATLAS -I/home/hanyu/Documents/kaldi/tools/ATLAS/include -msse -msse2 -pthread -g -fPIC -c -o CpuCompute.o CpuCompute_wrap.cxx
3.generate so file
g++ -shared CpuCompute.o -o _CpuCompute.so -Wl,--no-undefined -Wl,--as-needed -Wl,--no-whole-archive -Wl,-rpath=/home/hanyu/Documents/kaldi/tools/openfst/lib -rdynamic -Wl,-rpath=/home/hanyu/Documents/kaldi/src/lib /home/hanyu/Documents/kaldi/src/mylib/libmylib.so /home/hanyu/Documents/kaldi/src/cudamatrix/libkaldi-cudamatrix.so /home/hanyu/Documents/kaldi/src/feat/libkaldi-feat.so /home/hanyu/Documents/kaldi/src/ivector/libkaldi-ivector.so /home/hanyu/Documents/kaldi/src/transform/libkaldi-transform.so /home/hanyu/Documents/kaldi/src/hmm/libkaldi-hmm.so /home/hanyu/Documents/kaldi/src/gmm/libkaldi-gmm.so /home/hanyu/Documents/kaldi/src/matrix/libkaldi-matrix.so /home/hanyu/Documents/kaldi/src/tree/libkaldi-tree.so /home/hanyu/Documents/kaldi/src/thread/libkaldi-thread.so /home/hanyu/Documents/kaldi/src/util/libkaldi-util.so /home/hanyu/Documents/kaldi/src/base/libkaldi-base.so /home/hanyu/Documents/kaldi/tools/openfst/lib/libfst.so /usr/lib/libatlas.so.3 /usr/lib/libf77blas.so.3 /usr/lib/libcblas.so.3 /usr/lib/liblapack_atlas.so.3 -lm -lpthread -ldl -lpython2.7
