32 bit compiler vs. 64 bit compiler

[luke2006]

Following the question: we use a 64 bit system but we have only a 32 bit fortran compiler.so there is no
access to alibrary (which"belongs" to the 64 bit system). it there any possibilty to getany kind of access to this library?!
Thanks for answers.

If you are using a Fortran compiler from the last 5 years, there should be a companion 64-bit compiler available (with a few exceptions, such as cygwin, for which there are no 64-bit libraries anyway). 32/64-bitness of the compiler and libraries must match.

As Tim says, the standard installation provides both the 32-bit and 64-bit compilers. However, you may not see the 64-bit compiler if you didn't install the "x64 Compiler and Toiols" support with Visual Studio (applies only if you separately obtained Visual Studio and have the Professional or higher edition.) See the Fortran release notes for instructions in how to configure Visual Studio for 64-bit compilation.
