[ldmMcidas #LMZ-903767]: ldm-mcidas installation

Hi again,

No worries.

OK, now I understand.  The link error you sent previously:

gcc -O -o area2png alarm.o commonsubs.o imgsubs.o pngsubs.o rtesubs.o 
area2png.o -L/usr/local/ldm/lib -lX11 ../port/misc/libudport.a 
-L/usr/local/ldm/opt/netcdf/lib -L../libpng -lpng -L../zlib -lz -lm || (rm -f 
area2png; exit 1)
alarm.o: In function `alarm_on':
alarm.c:(.text+0x79): undefined reference to `udebug'
imgsubs.o: In function `ReplaceToken':
imgsubs.c:(.text+0x23): undefined reference to `udebug'
imgsubs.c:(.text+0x57): undefined reference to `serror'
imgsubs.c:(.text+0xe0): undefined reference to `udebug'
imgsubs.o: In function `GiniFileName':
imgsubs.c:(.text+0x28b): undefined reference to `udebug'
imgsubs.c:(.text+0x3b0): undefined reference to `uerror'
imgsubs.c:(.text+0x407): undefined reference to `udebug'
imgsubs.c:(.text+0x41e): undefined reference to `udebug'
imgsubs.c:(.text+0x435): undefined reference to `udebug'

is saying that entry points that should/are in the LDM library could
not be found.  Closer examination of the gcc line above shows that the
reference to the LDM library is missing.  This must mean that your
setting of the LD_LDM environment variable is incorrect:

export LD_LDM=-L${LDMHOME}/lib -lldm

The problem is that the values on the right hand side of the '=' sign
need to be enclosed by a quote:

export LD_LDM='-L${LDMHOME}/lib -lldm'

Compare this to other settings that you are using:


export CPPFLAGS='-DNDEBUG -Df2dFortran'

export FFLAGS='-O -Wuninitialized -fno-automatic'

export LD_LDM=-L${LDMHOME}/lib -lldm

export CPP_MCIDAS='-I${MCIHOME}/inc'
export LD_MCIDAS='-L${MCIHOME}/lib -lmcidas'

The setting for LD_NETCDF also needs quotes:

export LD_NETCDF=-L${NETCDFHOME}/lib -lnetcdf

So:

change:

export LD_LDM=-L${LDMHOME}/lib -lldm
export LD_NETCDF=-L${NETCDFHOME}/lib -lnetcdf

to:

export LD_LDM='-L${LDMHOME}/lib -lldm'
export LD_NETCDF='-L${NETCDFHOME}/lib -lnetcdf'

then make sure that the new settings are active; then run
'make distclean'; and then rerun configure; and then run make.
