Custom shared objects reduce the collection of functions available in Intel MKL libraries to those required to solve your particular problems, which helps to save disk space and build your own dynamic libraries for distribution.
The Intel MKL custom shared object builder enables you to create a dynamic library (shared object) containing the selected functions and located in the tools/builder directory. The builder contains a makefile and a definition file with the list of functions.
Note
The objects in Intel MKL static libraries are position-independent code (PIC), which is not typical for static libraries. Therefore, the custom shared object builder can create a shared object from a subset of Intel MKL functions by picking the respective object files from the static libraries.
