# qd-config(1)

determine flags for compilation and linking

## NAME

qd-config - determine flags for compilation and linking

## SYNOPSIS

**qd-config** **\[***options***\]**

## DESCRIPTION

To link a Fortran-90 program with the C++ qd library, it is  recommended to link with the C++ compiler used to generate the library.   The Fortran 90 interface (along with a C-style main function calling  *f\_main*) is found in the qdmod library.  The **qd-config** script can be used to determine which flags to pass to compile and link your programs.
