A clue from your error log:
/seadas/lcl/ocssw/opt/src/hdf5/hdf5-1.8.18/build/bin/H5test_FortranHavekind: /seadas/lcl/ocssw/opt/lib/libgfortran.so.3: version `GFORTRAN_1.4' not found
Why is your compiler looking for gfortran in $LIB3_LIB?

I'll keep working on it, but we do not have an estimate of how long it will take.

This suggests using the -no-pie compile option:https://stackoverflow.com/questions/50213089/linking-error-with-gcc-g-7-3-0-on-ubuntu-18-04You could edit $OCSSWROOT/CMakeLists.txt   # standard Linux bits...-  set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -std=c99 -D_XOPEN_SOURCE=600 -D_DEFA...

After making those changes, I'd start fresh: delete the existing build directory, then follow the build instructions in README.md, omitting the download steps.I'd also use just "make" instead of "make -j 20".   Leaving out the "-j" parameter will run o...

The AA tool is a part of the Science Data Toolkit that we don't use, so that's not the problem.This is really bizarre.  Is /seadas/lcl on a remote disk, that maybe just glitched out for a second?Please try:ls -l $LIB3_DIR/src/sdptk/TOOLKIT/bin/INSTALL-ToolkitMine looks like:-rwxr-xr-x 1...
