gfortran -g -O2 -fPIC -c misc_rand.f misc_rand.f:111.36:
parameter(umask = -2147483648) ! most significant w-r bits 1 Error: Integer too big for its kind at (1)
Thanks for the report. This compiled for me on linux, using gfortran 4.1.1 and 4.1.2, and obviously works in g77. I do see a reference that -2**31 is no longer a valid integer _constant_ in gfortran, but that it can be (oddly enough), a valid integer _value_. Weird. I don't have an installation of gfortran 4.2 easily available. Would you be willing to try this change? Comment out the parameter(umask ...) line, and simply set umask at the beginning of the executable statements ****************************************************************************************** misc_rand.f lines 110,111,112 should read: parameter(mata = -1727483681) ! constant vector a c parameter(umask = -2147483648) ! most significant w-r bits parameter(lmask = 2147483647) ! least significant r bits misc_rand.f lines 129,130,131,132 should read: c mag01(x) = x * mata for x=0,1 c umask = -2147483648 ! most significant w-r bits if(mti.ge.n) then ****************************************************************************************** That seems like it would be the easiest fix to me.
