A lot of these options are redundant; they're either on by default or turned on by enable-everything. Some options you may not want to use; --enable-complex has a lot of overhead on Real-valued problems, and --enable-reference-counting is probably unnecessary when you're not debugging. --enable-perflog (turned on by --enable-everything) has noticeable overhead too. Anyway, when you do get things the way you want, send us the .spec file? We haven't built RPMs of libMesh in too long. > The examples ex17 ends up with a seg fault : > > *************************************************************** > * Running Example ./ex17-opt -n 5 > *************************************************************** Would you try running with METHOD=dbg? We might catch some internal error condition before the segfault. Anyway, I can't replicate this segfault with SLEPc 2.3.1, PETSc 2.3.1p16, and MPICH 1.2.7, but OpenMPI is easy enough to install so I'll try again with that later. There's definitely some bug with ex17 and --enable-complex; for me it dies on a zero pivot when PETSc starts building a preconditioner. --- Roy ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
