#704: Carpet complains about lack of mpi after ExternalLibraries/OpenMPI is built
---------------------+------------------------------------------------------
 Reporter:  bmundim  |       Owner:     
     Type:  defect   |      Status:  new
 Priority:  major    |   Milestone:     
Component:  Cactus   |     Version:     
 Keywords:           |  
---------------------+------------------------------------------------------
 I was able to compile ExternalLibraries/OpenMPI successfully, but the
 Cactus
 compilation stops afterwards with the message:

 /home/bruno/tmp/einstein_dev_maxwell/Cactus/arrangements/Carpet/CarpetLib/src/make.configuration.defn:5:
 *** Configuration error: The Carpet thorns require MPI.  Please configure
 with MPI, or remove the Carpet thorns from the ThornList..  Stop.
 make: *** [einstein] Error 2

 I indicated in my configuration file the following options:

 OPENMPI_DIR = BUILD
 OPENMPI_INSTALL_DIR = /home/bruno/local/gcc4.6.1/openmpi-1.5.4

 I have then tried to indicate in my config file these extra options
 after the library was built (and the rest of Cactus compilation stopped):

 OPENMPI_DIR = /home/bruno/local/gcc4.6.1/openmpi-1.5.4
 OPENMPI_INC_DIRS = /home/bruno/local/gcc4.6.1/openmpi-1.5.4/include
 OPENMPI_LIB_DIRS = /home/bruno/local/gcc4.6.1/openmpi-1.5.4/lib

 The config-info file does reflect these choices afterwards, and apparently
 the flag indicating the presence of mpi library, HAVE_MPI, was set
 correctly
 at ~/Cactus/configs/einstein/bindings/Configuration/Capabilities:

 grep -i have_mpi *
 cctki_MPI.h:#define HAVE_MPI     1
 make.MPI.defn:HAVE_MPI     = 1

 however since I didn't use the old mechanism to tell Cactus about MPI, the
 ~/Cactus/configs/einstein/config-data/make.extra.defn doesn't have
 anything
 indicating the presence of mpi library there.

 It seems to me a compilation order issue. Somehow HAVE_MPI definition is
 coming
 after Carpet compilation, triggering this error then.

 Does anyone have any idea where I should look at in order to fix this
 problem?

 Thanks,
 Bruno.
