samskalicky opened a new issue #14236: Makefile plugins target needs mkldnn dependency URL: https://github.com/apache/incubator-mxnet/issues/14236 ## Description Building MXNet from source and enabling the WarpCTC plugin following these instructions: https://github.com/apache/incubator-mxnet/tree/master/example/ctc#ctc-loss-in-mxnet fails to build on Ubuntu with ```make -j$nproc``` because it depends on mkldnn which wasnt compiled yet. This is due to a missing makefile dependency on the plugin build target. Heres the error message: ``` In file included from include/mxnet/./op_attr_types.h:36:0, from include/mxnet/operator.h:40, from plugin/warpctc/./warpctc-inl.h:31, from plugin/warpctc/warpctc.cc:27: include/mxnet/././ndarray.h:41:22: fatal error: mkldnn.hpp: No such file or directory #include <mkldnn.hpp> ^ compilation terminated. make: *** [build/plugin/warpctc/warpctc.o] Error 1 ```
