Greg, I built the LDM package on the following system: $ uname -a SunOS buddy.unidata.ucar.edu 5.10 Generic_Patch i86pc i386 i86pc using the both gcc 4.0.2 and gcc 3.4.5. It was necessary to restrict the build to supporting only small (i.e., less than 4 GB) product-queues: $ ./configure --disable-max-size ... If that is acceptible, then you might try that option.
