GETFILEINFOQQ in 64 bit Fortran

[Chris_G_2]

I am using the Visual Fortran Compiler XE 15.0.0.070 running under Windows 7.

My program compiles and links correctly in 32 bit mode, but in 64 bit mode I get

error #6284: There is no matching specific function for this generic function reference.   [GETFILEINFOQQ]

I am also using the Math Kernel Library with the option /Qmkl:parallel. I get the following error messages associated with this:

ifort: command line warning #10159: invalid argument for option '/Qmkl'

The compiler command line is:

/nologo /O3 /Qopt-prefetch=2 /assume:buffered_io /Qip /Qopt-matmul /module:"x64\Release\\" /object:"x64\Release\\" /Fd"x64\Release\vc100.pdb" /check:none /libs:dll /threads /Qmkl:parallel /c

The linker command line is:

/OUT:"x64\Release\SquallDll1.dll" /NOLOGO /MANIFEST /MANIFESTFILE:"x64\Release\SquallDll1.dll.intermediate.manifest" /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /SUBSYSTEM:WINDOWS /IMPLIB:"C:\Users\chris\Documents\Visual Studio 2010\Projects\SQUALL v1.2\64 bit\DLL\SquallDll1\x64\Release\SquallDll1.lib" /DLL /qnoipo

Should I be using other libraries?

I can't reproduce error #6284 with my own example (tried both IA-32 and Intel 64 compilers).  You'll need to provide your own reproducer.  My command line was:

/O3 /Qopt-prefetch=2 /assume:buffered_io /Qip /Qopt-matmul /module:"x64\Release\\" /object:"x64\Release\\" /Fd"x64\Release\vc120.pdb" /libs:dll /threads /Qmkl:parallel /c

Regarding 'invalid argument for /Qmkl' -- you did install MKL along with the compiler, right?

the last parameter of GETFILEINFOQQ is a handle which is 4 bytes for win32 and 8 bytes for win64. Having  the wrong byte count on the call will probably be the problem.

use ifwin, only: handle
integer(handle) :: handle_variable_name

will probably fix it.

Thanks app4619 - it looks sensible to me and I'll try it.

Patrick: Yes I installed MKL; I have a folder ......./Intel/Composer XE 2015/mkl/bin/intel64 containing mklvars_intel64.bat and ......./Intel/Composer XE 2015/mkl/lib/ia32 and intel64.

Thanks for your help

Hello Chris,

Thanks for confirming you have MKL installed.  Regarding your issue with /Qmkl:parallel, a colleague who has VS2010 installed will check if the issue can be reproduced with that particular version of VS (I couldn't reproduce it with VS2013).  It's possible to have a defect in the IDE integration that only exists for a particular combination of VS + compiler.  I'll update this thread as I learn more.

This particular error has nothing to do with VS version nor with MKL. It is simply an incorrect declaration of the argument to GETFILEINFOQQ.

Thanks everyone. The fix suggested by app4619 fixes everything except an error message

patmat.lib(PATMAT.dll) : fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'x64'

which is telling me I need to recompile PATMAT.dll as 64 bit, which I will now do.
