------- Comment #2 from tobias dot burnus at physik dot fu-berlin dot de 2006-08-22 21:08 ------- Using gfortran 4.1.2 20060705 (prerelease) (SUSE Linux) and GNU Fortran 95 (GCC) 4.2.0 20060822 (experimental) it compiles and gives the output (from the program):
det for matrices bigger than 4x4 not implemented John Chodera, I would really recommend to update to 4.1.x or to 4.2-snapshots as gfortran in GCC 4.0.x is rather buggy. See http://gcc.gnu.org/wiki/GFortranBinaries for binary GCC versions. In addition: As the NAG compiler points out: --------------------------------------------------- Error: Explicit interface required for DET from MAIN - argument A (no. 1) is an assumed-shape array --------------------------------------------------- The problem is that Fortran passes an array differently for A(*) or A(n) than for A(:). The latter is called assumed-shaped array and is an addition to Fortran 90 (the former also work with Fortran 77). In order to let the compiler know that you want to pass an assumed-shaped array, you need to either create a module, which contains the function "det", or you put it below "contains" in the "program" section or you write an interface in the "program" section. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28809
