</span>ESSL I guess (only case covered in the configure).<br>
<br>
ESSL evolved quite a lot since the "old days". I have no access to a machine where ESSL (ESSL linux or ESSL BlueGene?) is deployed but if someone remember which routine was not present we can easily check. It is always possible to force a behaviour of the linker where libraries are linked in this order {ESSL, Netlib LAPACK, Netlib BLAS}, it is a flag to turn in the make.inc<br>
