mjsML commented on issue #17181: Fail to build mxnet from source URL: https://github.com/apache/incubator-mxnet/issues/17181#issuecomment-573948456 agreed ... as I mentioned above it's a well documented [issue](https://github.com/xianyi/OpenBLAS/wiki/faq#debianlts) with OpenBLAS and debian based distros. > Debian and Ubuntu LTS versions provide OpenBLAS package which is not updated after initial release, and under circumstances one might want to use more recent version of OpenBLAS e.g. to get support for newer CPUs >Ubuntu and Debian provides 'alternatives' mechanism to comfortably replace BLAS and LAPACK libraries systemwide. >After successful build of OpenBLAS (with DYNAMIC_ARCH set to 1) ``` $ make clean $ make DYNAMIC_ARCH=1 $ sudo make DYNAMIC_ARCH=1 install ``` Basically the symbol mentioned above is missing from the default binaries that ships with debian based distros, so OpenBLAS needs to be rebuilt from latest source with this flag to force the compiler to output the symbol that the linker here is looking for(in this instance the old "gotoblas" symbol).
