dnl Michele Martone's proposal for a transition towards the GNU build system for the PSBLAS library
|
|
dnl
|
|
|
|
dnl Process this file with autoconf to produce a configure script.
|
|
dnl
|
|
dnl usage : aclocal -I config/ && autoconf && ./configure && make
|
|
|
|
dnl then : VAR=VAL ./configure
|
|
|
|
dnl In some configurations (AIX) the next line is needed:
|
|
dnl MPIFC=mpxlf95 ./configure
|
|
|
|
dnl then : ./configure VAR=VAL
|
|
dnl then : ./configure --help=short
|
|
dnl then : ./configure --help
|
|
|
|
dnl the PSBLAS modules get this task difficult to accomplish!
|
|
dnl SEE : --module-path --include-path
|
|
|
|
dnl NOTE : There is no cross compilation support.
|
|
|
|
dnl NOTE : missing ifort and kl* library handling..
|
|
dnl NOTE : odd configurations like ifc + gcc still await in the mist of the unknown
