# Be sure to set LAMHOME properly so that hcc/hcp/hf77 use the right
# libraries/include files (to avoid conflicts if the user may already
# have a LAM installed, and already have LAMHOME set somewhere else).

# Before you ask, yes, the final "cat" on the ROMIO_TEMP line is
# necessary.  If it is not there and grep does not find '-g' in
# $(CFLAGS), grep will return 1, which will cause "make" to bail.  But
# apparently only the *last* command's return code will be returned to
# make.  Cat will always return 0, which means that "make" won't bail.
# Really weird.

# Another bug in ROMIO -- we have to go set the unix permissions on
# directories under $LAMHOME/include to be 755 again.  ROMIO does a
# chmod 644 $LAMHOME/include/* -- ick!  The ROMIO authors have been
# notified of this.  13 June 1999/JMS.

# Automakeizm -- check to see if we already built ROMIO.  "make
# install" implicitly invokes "make all" first (in a roundabout way).

# VPATHizms -- check to see if the "romio" dir exists.  If it doesn't,
# make it.  Then we have to go find the configure file.  If it's not
# in the romio dir, check ../$(top_srcdir)/romio.  If it's not there,
# barf.  Set LAM_TOP_BUILDDIR and LAM_TOP_SRCDIR as appropriate (hcc
# uses these variables to reset -I and -L paths).  Also, ROMIO doesn't
# seem to be able to create its "test" directory properly (if it
# doesn't exist), so we have to make it.

# libtoolizms -- set the underlying LAMHCC and LAMHF77 to have libtool
# in them.  Even though ROMIO will not create any executables, and
# therefore strictly won't need libtool, during ROMIO's configure, it
# checks for libmpi, etc., and makes some dummy executables, and
# therefore does need libtool.  Ugh!!

# Arrgh -- we have to forcibly remove -I$(top_srcdir)/share/include
# form $(CFLAGS) because relative to romio/, that directory doesn't
# exist, because $(top_srcdir) is replaced *here* -- not in romio/.
# Hence $(top_srcdir) is replaced with ., and ./share/include doesn't
# exist relative to romio.  $#%@#%@#%#$!!!  So we have to sed it out
# of $(CFLAGS) and put it in a temporary environment variable and use
# that instead.

# Ick.  Because of the way MPI 2 C++'s configure.in works, it expects
# to find an installed LAM/MPI.  So it expects to find hcp/lamboot in
# the same directory (under the assumption that it's $prefix/bin).  So
# we have to sym link lamboot into tools/hcc during the build.  Ugh!
# We really should put a hook in MPI 2 C++ to make this better (a la
# ROMIO's hook for MPICH), but not right now...

# VPATHizms -- check to see if the "romio" dir exists.  If it doesn't,
# make it.  Then we have to go find the configure file.  If it's not
# in the romio dir, check ../$(top_srcdir)/romio.  If it's not there,
# barf.  Set LAM_TOP_BUILDDIR and LAM_TOP_SRCDIR as appropriate (hcc
# uses these variables to reset -I and -L paths).  

# libtoolizm -- very, very painful.  We must set libtool as the
# underlying LAMHCP because mpi2c++'s configure checks for the
# presence of libmpi, etc.  libtool does not understand C++ compilers
# or options, so an additional --mode switch must be insertted.  hcc
# had to be modified to look for libtool as the first arg in
# conjunction with building LAM and compiling C++ programs.  It will
# insert the right --mode switch, as appropriate.  It will also ditch
# the libtool arguments if it finds a -E, so that the *real*
# underlying compiler can act as a preprocessor.  Woof -- what a day.

# What sucks even worse is that CVS and the distscript.csh don't
# preserve timestamps properly, hence the automake-ized mpi2c++
# project tries to re-run aclocal and friends.  This is disasterous,
# because we don't have the maintainer tree here -- just the
# distribution tarball (e.g., acconfig.h is not shipped, so autoheader
# barfs).  So we have to do a really gross touch to get all the
# timestamps equal.  Don't laugh; it's the only thing that I can think
# to do.  :-(
