Licensing Changes

Free Intel Visual Fortran for students!

Intel Fortran is now available under a free, non-commercial license for qualified students on Linux, OS X and WIndows. See for more details.

Note: If you don't already have a supported Microsoft Visuall Studio installed, you'll need to get one first as the student license doesn't include the VS Shell-based IDE. The free Visual Studio 2013 Community Edition will do.

OS X 10.9 Xcode 5 error ld: library not found for -lcrt1.10.6.o

Environment:  OS X 10.9 (Mavericks) and Xcode 5.0

Command line compilations/links fail with "ld: library not found for -lcrt1.10.6.o"

Affected compiler:  Intel Composer XE 2013 Update 1

Root cause:  Xcode 5.0 installation does not install all command line tools (include files, libraries, SDKs) need for the compiler to link user applications. 

Оптимизировали, оптимизировали, да не выоптимизировали!

Оптимизация? Конечно, каждый сталкивался с данной задачей при разработке своих, сколь-нибудь значительных, требующих определённых вычислений, приложений. При этом способов оптимизировать код существует огромное множество, и, как следствие, различных путей сделать это в автоматическом режиме с помощью опций компилятора. Вот здесь и возникает проблема – как выбрать то, что нужно нам и не запутаться?

Use Fortran DLL in C++

I want to use a DLL file that I created in Fortran using ifort in a C++ program I don't know how to do it on the C++ side so far I have

subroutine func01( a ) bind(C,name="func01")
implicit none
character(len=1), dimension(90) , intent(in) :: a
character(len=30), dimension(3) :: b
integer*4 :: count,i,j

do j=1,3
do I=1,30

FORTRAN 64Bit Project


I have been working on porting several 32bit projects to 64bit platform. Tthe main program is a C\C++ project and it calls  Fortran functions (similarly, some of Fortran functions call C\C++ functions as well).  Projects compile and link juts fine for 32x.  Once, I change it to  it to 64x, I am getting lots of unresolved external symbol errors like this one
