Thanks!
I did as your suggestions, and used CFLAGS=-g and --with-debug, still shows "segmentation fault",
jgche: ~\>ln -s lam-7.1.2-debug lam-eth
jgche: ~\>cd lam-test/
jgche: ~/lam-test\>lamboot -v lamhosts
Segmentation fault
jgche: ~/lam-test\>lamboot -d lamhosts
Segmentation fault
jgche: ~/lam-test\>ls -l
total 4
-rw-rw-r-- 1 jgche jgche 7 Apr 23 08:26 lamhosts
jgche: ~/lam-test\>
but no corefile was created.
attached files are config.log and make.log

This is certainly quite odd and should not happen.
Can you try running "lamboot -d lamhosts" with 7.1.2? That might give a bit more output.
If that doesn't reveal anything useful, could you recompile LAM with debugging symbols enabled (e.g., "./configure CFLAGS=-g ...."), ensure that your coredumpsize is unlimited, and run it again? This should then generate a corefile -- if you could send the backtrace from that, it would be most useful.
Thanks!

Subject: LAM: can gcc 3.2 and kernel 2.4.20 suit lam-7.1.2 or not? Or other problem for lam-7.1.2?
I cannot install lam-7.1.2 on our cluster with dual Xeon and myrinet. Its gcc version is:
jgche: ~\>gcc -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --host=i386-redhat-linux --with-system-zlib --enable-__cxa_atexit
Thread model: posix
gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)
its kernel seems to be 2.4.20-28.8smp (I'm not a manager, who will not install lam-mpi, thus I want install for myself)
I compiled lam-7.1.2 without problem, please see the attached config.7.1.2.log and make.7.1.2.log. However, when I run lamboot, I got
jgche: ~\>cat lamhosts
admin1
jgche: ~\>lamboot -v lamhosts
Segmentation fault
jgche: ~\>
Except for mpif77, mpicc, mpic++, if I excuted any other excutable files in /people/jgche/lam-7.1.2-eth/bin, I got "Segmentation fault"! I cannot fix the problem. Thus, I tried to install lam-6.5.7, since I thought this version was released in Oct 2002, almost the same time as that of gcc 3.2. And now it seemed to be ok.
jgche: ~\>rm lam-eth
jgche: ~\>ln -s lam-6.5.7-eth/ lam-eth
jgche: ~\>lamboot -v lamhosts
LAM 6.5.7/MPI 2 C++/ROMIO - Indiana University
Executing hboot on n0 (admin1 - 1 CPU)...
topology done
please refer also to the attached config.6.5.7.log and make.6.5.7.log.
What is this problem? Is the gcc version problem? or kernel? or others? How can I fix the problem?
Thanks!
