Here I have $ pkg-config --libs blas -lrefblas $ pkg-config --libs lapack -lreflapack -lrefblas So the following configure works here ../configure --with-blas=refblas --with-lapack=reflapack Or you may get something like this (all on one line) to work ../configure --with-blas=`pkg-config --libs blas | sed 's:-l::g' | sed 's:[[:space:]].*$::g'` --with-lapack=`pkg-config --libs lapack | sed 's:-l::g' | sed 's:[[:space:]].*$::g'` There may be other things that are missing but I'm able to generate the makefiles with the above.
