Compilation of user code requires access to the
fir_compiler_v7_2_bitacc_cmodel.h header file
and the header file of the Multiple Precision Integers and Rationals (MPIR) Library
(MPIR), gmp.h. The header files must be copied to a
location where they are available to the compiler. Depending on the location chosen,
the ‘include’ search path of the compiler might need to be modified.
The fir_compiler_v7_2_bitacc_cmodel.h
header file includes the MPIR header file, so these do not need to be explicitly
included in source code that uses the C model. When compiling on Windows, the symbol
NT must be defined, either by a compiler option, or in user
source code before the fir_compiler_v7_2_bitacc_cmodel.h header
file is included.
