Hi Brendon,
re: LDM shared library not found when trying to run newly built ldm-mcidas
decoders
Here is the set of environment variable definitions that I use when building
ldm-mcidas v2012 in my CentOS 6.5 VM development environment:
Bash/Bourne shells:
# For ldm-mcidas builds
CC=cc
FC=gfortran
CPP_MCIDAS='-I/home/mcidas/mcidas2009/src'
LD_MCIDAS='-L/home/mcidas/lib -lmcidas'
CPP_NETCDF='-I/home/mcidas/mcidas2009/netcdf/libsrc'
LD_NETCDF='-L/home/mcidas/lib -lnetcdf'
LD_MATH='-lm'
LD_LDM='/home/ldm/lib/libldm.a /home/ldm/lib/libxml2.a'
#LDFLAGS='-Wl,-rpath,/home/ldm/lib'
#LD_LDM='-L/home/ldm/lib -lldm -lxml2'
LD_FORTRAN='-static -lf2c'
LD_X11=''
FTPDIR=$HOME/ldm-mcidas/ftp
FTPBINDIR=$HOME/ldm-mcidas/ftpbin
export CC FC CPP_MCIDAS LDFLAGS LD_MCIDAS CPP_NETCDF LD_NETCDF LD_MATH LD_LDM
LD_FORTRAN LD_X11 FTPDIR FTPBINDIR
To build using the shared LDM library and with "burning in" the location
of the shared LDM library, I uncomment the two commented lines above
and comment out the LD_LDM line:
# For ldm-mcidas builds
CC=cc
FC=gfortran
CPP_MCIDAS='-I/home/mcidas/mcidas2009/src'
LD_MCIDAS='-L/home/mcidas/lib -lmcidas'
CPP_NETCDF='-I/home/mcidas/mcidas2009/netcdf/libsrc'
LD_NETCDF='-L/home/mcidas/lib -lnetcdf'
LD_MATH='-lm'
#LD_LDM='/home/ldm/lib/libldm.a /home/ldm/lib/libxml2.a'
LDFLAGS='-Wl,-rpath,/home/ldm/lib'
LD_LDM='-L/home/ldm/lib -lldm -lxml2'
LD_FORTRAN='-static -lf2c'
LD_X11=''
FTPDIR=$HOME/ldm-mcidas/ftp
FTPBINDIR=$HOME/ldm-mcidas/ftpbin
export CC FC CPP_MCIDAS LDFLAGS LD_MCIDAS CPP_NETCDF LD_NETCDF LD_MATH LD_LDM
LD_FORTRAN LD_X11 FTPDIR FTPBINDIR

As I noted in my email earlier today, I much prefer to link against the
static LDM library as this allows one to roll the LDM back to
a version that predates versions in which the shared LDM library
is built.
NB: the HOME directory for 'ldm' in the examples above was /home/ldm.
This may have to be changed for your 'ldm' user.
Cheers,
Tom
