<DIV>Yes, as much additional information as you can provide. What OS (Linux 
distribution?) and compiler versions? What are the contents of that 
IpLimMemQuasiNewtonUpdater.lo file? It should be a ~10 line text file. If 
something went wrong during compilation of the IpLimMemQuasiNewtonUpdater.cpp 
source, the best way to figure out what’s happening is to upload full config.log 
files (both from the top-level and the Ipopt subdirectory), and a log of all the 
output from make to see if there were any unusual warnings or errors you may 
have missed.</DIV>
