Ross,
Thanks for the help. I am also using xlf90 v8.1. slight modifications
to your config.h file were necessary (my AMB_SRC was not
/nfs/auts/users/crowley/amber9/osx/src but was /usr/local/amber8/src )
;) and the SYSDIR pointed at a non-existent folder on my machine,
though pointing it to /lib made the compiling go smoothly.
unfortunately, then the make test failed for sander, though it worked
for leap. going back to my previous config.h file allowed the make
test to work again.
i compiled ambpdb with my config with -g and then looked at the crash
with gdb.
here's what it told me:
(gdb) run ambpdb
Starting program: /usr/local/amber8/exe/ambpdb ambpdb
Reading symbols for shared libraries .+++....... done
Program received signal EXC_BAD_ACCESS, Could not access memory.
0x00002b94 in main ()
(gdb) bt
#0 0x00002b94 in main ()
#1 0x8fe1a558 in __dyld__dyld_start ()
#2 0x8fe1a558 in __dyld__dyld_start ()
(gdb)
thanks again for your help,
justin
