I have a fully working version of amber compiled on another machine in
my department. I copied the source code accross to this machine, where I
have to use a different compiler.
on compiling a serial version of sander I get an error:
g95 -c -O3 -fno-second-underscore -ffree-form -I../../sander -o
../obj/random.o ../obj/random.f
In file ../obj/random.f:11
FUNCTION xrandom(idum)
1
Warning (139): Value of function 'xrandom' at (1) is never set
In file ../obj/random.f:22
FUNCTION irandom(idum,imax)

Warning (139): Value of function 'irandom' at (1) is never set
In file ../obj/random.f:11
FUNCTION xrandom(idum)

In file ../obj/random.f:47
sum = sum + xrandom(idum)
2
Error: FUNCTION 'xrandom' is of type REAL(4) at (1) and type REAL(8) at (2)
make[2]: *** [../obj/random.o] Error 1
I was able to prevent this error message appearing and complete the
compilation of sander by changing line 13 in
$AMBERHOME/src/dcqtp/src/util/random.F90 to read:
implicit double precision(a-h, o-z)
where before no code was included in the function xrandom(idum).
Once sander has been made in this way when I run it it behaves very very
oddly, for intance when simulating a box of just 375 TIP3P water
molecules at 273 K it's first action is to drop the temperature of the
simulation to ~60K and continue at that temperature.
Can anyone point me towards a fix for this?
Regards,
Martin Stennett.
