2.1 Building the Library

The CFITSIO code is contained in about 40 C source files (*.c) and header files (*.h). On VAX/VMS systems 2 assembly-code files (vmsieeed.mar and vmsieeer.mar) are also needed.

CFITSIO is written in ANCI C and should be compatible with most existing C and C++ compilers. Cray supercomputers are currently not supported.
