sorry i am a mathematician who can more or less program, so, please, forgive my low level question. I am building a 32bit dll with intel fortran 2013 from visual studio 2010 on windows.I need to call it from R ( a statistical program). which requires very simple single thread dlls (obviously no MP). At the office i have a 32bit single core processor and windows Xp and I can compile and call it OK. At home I have an i5 quadricore 64bit. on windows 7 and I don't have the single thread option in VS (so it always compiles with the /threads option). I believe this is why I get the message "#1 is not a valid win32 application" when I load a version compile at home. Can anyone suggest how i can select the single thread option from VS2010 or add a compiler directive at home?
many thanks, marco.
