I am glad things are working for you. However, I'd suggest NOT setting LD_PRELOAD. That causes the BLRC library to be loaded into everything you execute. We've not yet tested well enough you be certain this is 100% safe. I suspect that the LD_PRELOAD might be causing your problem with building the LAM examples. -Paul ? wrote: > > This is my installation records: > > +_______ BLCR Installation_________________________+ > ../configure --with-linux=/usr/src/linux-2.4.20-8 --with-system-map=/boot/System.map --prefix=$HOME/BLCR > make > make install > +--------------------------------------------------+ > > +______.bashrc modification for BLCR_______________+ > # for BLCR > export MANPATH=$MANPATH:$HOME/BLCR/man > export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/BLCR/lib > # In addition to using cr_run, processes may be made checkpointable by > # setting LD_PRELOAD to the full path of libcr library. > export LD_PRELOAD=$LD_PRELOAD:$HOME/BLCR/lib/libcr.so.0 > +---------------------------------------------------+ > > +______LAM/MPI-7.0.3 Installation___________________+ > ../configure --with-blcr=$HOME/BLCR --with-rpi=crtcp --prefix=$HOME/LAM-MPI > make > make install > +---------------------------------------------------+ > > +_____.bashrc modificatio for LAM/MPI_______________+ > export PATH=$PATH:$HOME/LAM-MPI/bin > export MANPATH=$MANPATH:$HOME/LAM-MPI/man > +---------------------------------------------------+ > > During the installations, no warnings nor errors. laminfo shows below: > LAM/MPI: 7.0.3 > Prefix: /home/xue/LAM-MPI/ > Architecture: i686-pc-linux-gnu > Configured by: xue > Configured on: Thu Nov 27 18:17:07 CST 2003 > Configure host: xeon736 > C bindings: yes > C++ bindings: yes > Fortran bindings: yes > C profiling: yes > C++ profiling: yes > Fortran profiling: yes > ROMIO support: yes > IMPI support: no > Debug support: no > Purify clean: no > SSI boot: globus (Module v0.5) > SSI boot: rsh (Module v1.0) > SSI coll: lam_basic (Module v7.0) > SSI coll: smp (Module v1.0) > SSI rpi: crtcp (Module v1.0) > SSI rpi: lamd (Module v7.0) > SSI rpi: sysv (Module v7.0) > SSI rpi: tcp (Module v7.0) > SSI rpi: usysv (Module v7.0) > SSI cr: blcr (Module v1.0.1) > > Then I start lamboot. --OK. > > I get into lam-mpi source folder and try to make examples, but something > annoying comes out: > _______________________________________ > Making examples in romio > make: *** wait: no child process.
