Dear Bertrand,
It seems that there is a problem with bugfix.34. This was created by Roberto
Gomperts of SGI so I am cc'ing him on this email so he can take a look into
it. For the time being please edit $AMBERHOME/src/config.h and remove any
occurances of '-i-static' Then try again. It think this will fix this.
Also, for reference can you run:
ifort -V
And let us know what it reports.
All the best
Ross

Dear Mr.Ross,
As you suggested I downloaded the latest bugfix.all
file available from amber.scripps.edu <

patched it. I gave the command as you specified in your mail.

I am getting the following error which I was not getting before ( when I
used only 32 bugfixes my compilation went fine at this stage ). Could you
point what I am doing wrong? Thanks in advance.

Dear Bertrand,
Firstly on an sgi_altix you should use:
./configure -nopar sgi_altix (for the non-parallel version, best to get
this working first)
and
./configure -mpi sgi_altix (for the parallel version.)
this way the correct libraries and compiler flags should be set.
The segfault is coming from the compiler and is a bug in the compiler itself
and there is not a lot we can do about it other than try to work around it.
This is Intel's fault and they should fix it. The problem is made more
complicated by the fact that some versions of the compiler work fine while
others crash. And even worse when you go to a newer compiler some previous
bugs are fixed and yet newer ones are introduced :-(.
Firstly though, what version of the compiler are you using? You should go
and get the very latest compiler just in case some of the bugs may have been
fixed.
Next obtain bugfix.all from the bugfixes page on amber.scripps.edu and patch
your source code with it.
Then cd $AMBERHOME/src
make clean
make
See how far the compiler gets before it segfaults. The following only
applies to the compilation of files in $AMBERHOME/src/sander. If the
compiler dies on a file outside this directory then please send me the make
log. If it segfaults on a specific file in src/sander then
cd $AMBERHOME/src/sander
edit that file and remove the first line of the file that reads "!
<compile=optimized>"
Next do "rm -f depend"
makedepend > depend
cd ..
make
Hopefully it will proceed beyond that file and perhaps segfault somewhere
else or maybe compile successfully. If it still segfaults on the same file
then edit $AMBERHOME/src/config.h and change
FFLAGS= -w95 -ftz -O2 $(LOCALFLAGS) $(AMBERBUILDFLAGS)
to
FFLAGS= -w95 -ftz -O0 $(LOCALFLAGS) $(AMBERBUILDFLAGS)
Then try make again.
Hopefully this will allow you to build a working copy of sander. Next run
the test cases and see how it does. Let me know if it fails on any,
particularly the QMMM ones since some versions of the Intel compilers had
problems with qm_link_atoms.f then let me know and I can explain how to work
around this compiler bug as well.
Failing all of the above see if you can get hold of ifort v8.1.025 for
Itanium (IA64) since this version I know to work out of the box.
Good luck....
Ross

Subject: Re: AMBER: Error - must define AMBERHOME environment variable
Dear Mr.Ross,
Thank you for your support. I herewith sending you the
compiler error message which I got while compiling with ifort_ia64 compiler.
The steps I followed are and the error message is as follows,
>cd $AMBERHOME/src
>./configure -p4 ifort_ia64
After this point I edited the the config.h file by adding "-ldl" flag
immediately following ifort wherever it is in the config.h file. Then I
issued the following command,
>make serial
My error messages are as follows,

If I reduce the optimisation level to "O2" instead of "O3" I am getting the
same error but at 1616 line number instaead of 1597th line. It would be
helpful if I can solve this problem and install amber9 in our SGI Altix. I
patched with the latest bugfix.all file from amber.scripps.edu site.
My machine specifications:
Machine Name: Altix 390
Processor Type: Intel Itanium
Operating system: ALTIX SGI Propack
ifort compiler version: Version 8.0
Many thanks in advance.
