Compile demo error

[ZuanXiao]

Hi, there! I have set the path with .pc file in config/ folder. After i make compile and make detect, i got the executable file detetcApp.out, but then i got an error when ./detectApp.out like the following:

./detectApp.out: symbol lookup error: /opt/intel/mkl/lib/intel64/libmkl_intel_lp64.so: undefined symbol: mkl_lapack_dgetrfnpi

which have been perplexing me for a long time. Actually, i cannot find the undefined symbol -- mkl_lapack_dgetrfnpi in my PC, and i am not sure whether it's the MKL error or some other code error or environment wrong.

My config is as follows: Ubuntu 16.04 dlib -- 19.10.0 MKL -- Intel parallel_studio_xe_2017_update4 boost -- 1.67.0 caffe -- which is ok cuda -- 8.0 opencv -- 3.2.0 with contrib

Thanks a lot!

Hi, If I remeber correctly, parts of dlib requires lapack to be installed - are you sure you have it installed and setup? Im out of office for some time, so I cant help you much. I think it should be something with your install/setup though, rather than this project. Hope it helps!

Thanks for your replying! I have checked that the lapack have installed correctly, but the problem remains. May be i will reconfigure the project environment later. Thanks!
