Re: IDL5.4 CALL_EXTERNAL crashes IDL under IRIX

[Ole B Christensen <bossing(at)dmi.dk>]

Dear Nigel and the rest that helped,

Nigels suggestion about rebuilding solved my problem! Thanks! I changed
the old commands

f77 -n32 -c read_grib.f
ld  -n32 -shared read_grib.o -L /home/climate/lib32 -lemos -o
libread_grib.so

into the compound command

f77 -n32 read_grib.f -shared -lemos -L /home/climate/lib32 -o
libread_grib.so

and ended up with something that worked.

Greetings, Ole (Danish Meteorological Institute)
