Error Cannot Change Attributes Of Use-associated Symbol At 1

string.join(["Tk 4.2p2", "Python 1.4", "Win32", "free"], "for") 6. when i use ifort to compile, I got the error:This array or function or substring is invalid in constant expressions. [NULL] type(ClusterNode),pointer :: son1=>null() ! In section 11.2.1, the standard seems to say that one can add the "volatile" attribute to the local instance of an entity accessed via host association.

Does the standard forbid the use of the "volatile" attribute with a function result variable (and, if so, where in the document is the prohibition)? > cat fcn.f90 function In section 11.2.1, the standard seems to say that one can add the > "volatile" attribute to the local instance of an entity accessed via > host association.

There is a bit of "silliness" in the f95 module procedure statement. https://software.intel.com/en-us/forums/intel-fortran-compiler-for-linux-and-mac-os-x/topic/270770 Yes, I know that you accessed it via a USE statement, but that doesn't make it a module procedure. Could you take a look please? Is the following code legal? > cat mod13.f90 module mod13 implicit none integer :: v13 end module mod13 > cat mod13a.f90 module

So I don't think this is a compiler bug, other than perhaps insomuch as the error message could be better. his comment is here Uncommenting the following statement !! C TYPE (DN) DX(*),DY(*),DTEMP INTEGER I,INCX,INCY,IX,IY,M,MP1,N 60 DDOT = DTEMP RETURN END CVF can successfully compile it. Or maybe I don't understand its meaning?

Comment 2 Tobias Burnus 2013-05-03 08:59:48 UTC decl.c's gfc_match_null has: gfc_intrinsic_symbol (sym); if (sym->attr.proc != PROC_INTRINSIC && (!gfc_add_procedure(&sym->attr, PROC_INTRINSIC, sym->name, NULL) || !gfc_add_function (&sym->attr, sym->name, NULL))) return MATCH_ERROR; Failing is the But no compiler yet claims to fully conform to F2003. If nobody can see why this check is needed, I will submit the patch to remove the check. http://optimisersonpc.com/error-cannot/error-cannot-find-symbol-antlr.html Leo van Kampenhout lvankampenhout at gmail.com Fri Oct 1 04:05:11 CDT 2010 Next message: [petsc-users] petsc and meshless type method: Forming parallel coefficient matrix Messages sorted by: [ date ] [

Or put a generic interface block for foo in module a, with just foo1 as a specific. Unify with traverse_symtree. (gfc_traverse_ns): Call gfc_traverse_symtree according to new interface.

(build_common_decl, new_segment, translate_common): Not to mention a module, once compiled, should contain all the information necessary for the USE statement. !

The f2003 fix is better. -- Richard Maine | Good judgement comes from experience; email: last name at domain . For comparison, the following (also valid) code is accepted: PROGRAM MAIN INTEGER FOO COMMON /FOO/ BAR END ANALYSIS ======== Function gfc_add_common, in file symbol.c, says: gfc_add_common (symbol_attribute * attr, locus * A blank prohibition would remove the need for placing constraints, possibly hundreds of constraints, throughout the standard. z.f90 > program z >     use foo >     real x >     x = sin(x) > end program z > > gfc -o z foo.f90 s1.f90

The example is derived from fma3d in SPEC2k. I forgot to add the correct files to the makefile, for I put the module in a seperate file (grid.F). The error message is not emitted if the declaration of R is uncommented. ! -- test.f90 MODULE M INTRINSIC :: NULL !! navigate here Mostly the whole business about restricting it to module procedures is what seems silly to me.

In fact, ibm xlf rejects it, too. Comment 2 Andrew Pinski 2003-12-02 15:55:52 UTC Confirmed. Steve Lionel Developer Products Division Intel Corporation Nashua, NH User communities for Intel Software Development Products http://softwareforums.intel.com/ Intel Fortran Support http://developer.intel.com/software/products/support/ My Fortran blog http://www.intel.com/software/drfortran Wed, 08 Jul The correct makefile rule for the main program (main.F) is: main: grid.o main.o chkopts -${FLINKER} -o main grid.o main.o ${PETSC_KSP_LIB} ${RM} main.o grid.o Thanks again.

The restriction given is not a constraint and so a Fortran processor is not required to diagnose the nonstandard usage to be standard conformant.
