While BLAS is truly a PITA, most systems have quite sane cBLAS bindings (notable exception is OpenBLAS...) and often it is enough to check whether the system has some libcBLAS.so somewhere in the path. > > the big issue of having a header only BLAS are the long, long, long compile times. Two solutions to this: - precompiled headers - from a header only C++BLAS library it is trivial to create a compiled library for the common cases where all elements have the same type.
