Can not compile from source when tflite is enabled

Troubleshooting
#1

Hi,

I am trying to build TVM from source, but I am facing some problems when enabling the tflite support. Without tflite I am able to complete the building process (libtvm.so).

Any insight would be greatly appreciated.

Thanks

Expected behavior

Building TVM from source with tflite enable

Actual behavior

When “make” try to link libtensorflow-lite.a, the process fails to do to some undefined references, the first being

/usr/bin/ld: /home/user/TVM/tflite_build/libtensorflow-lite.a(rfft2d.cc.o): in function tflite::ops::builtin::rfft2d::Rfft2dImpl(int, int, double**, int*, double*)': rfft2d.cc:(.text+0x916): undefined reference to rdft2d’
