Pro Fortran combines the first native, full ANSI standard Fortran 90 for
Power Macintosh, the latest PPC version (4.4) of Absoft's best selling VAX
compatible FORTRAN 77, and Absoft's PPC native C & C++ compilers into
one easy-to-use development system. It enables new code development utilizing
the modern features and flexibility of Fortran 90, efficient reuse of proven,
legacy FORTRAN 77 code, and mixed F90/F77/C/C++ development from a single
environment. A common runtime library and modified linker ensure full link
compatibility between each language, so you can utilize F90, F77, and C/C++
code modules in a single application. Pro Fortran generates native PPC code
only.
To compile source code1.f90 in the new free form:
f90 code1.f90 -o prognameTo compile source code2.f in the old fixed form:
f90 code2.f -o prognameBelow is a list of the most important switches for the Absoft Fortran 90 compiler.
-604 # Optimize for the PPC 604 -c # Generate object files only -dB # Perform syntax check only of the source code -dp # Convert DOUBLE PRECISION to REAL -dq # Continue compilation after 100 errors (default abort) -ea # Abort compilation on first error -ej # One trip DO loops (F66 compatibility) -en # Generate warnings for all non-standard usage -eR # Default recursion -F # Use files for temporary storage -f fixed # Set source code form to fixed -f free # Set source code form to free -g # Generate debugging information -gmin # Generate minimum debugging information -I path # Define path to find include files -link <arg> # Passdirectly to linker -macModFiles # Search {f90includes} for module files -N9 # Frequent Command-period checks -N11 # Use 32-bit branches -N124 # Traceback, prints routines names to stdout -O # Basic optimizations -o file # Specify output file name -p file # Specify module file name -p dir # Specify directory to look for module files -prof # Adds profiling code (PPC only) -plainappl # Create application without MRWE -s # Force all program storage to be static -share # Link with shared version of runtime libraries -tool # Create MPW Tool instead of application -V # Show compiler version information -v # Show progress information -W80 # Allow wide format source lines up to 80 columns -W132 # Allow wide format source lines up to 132 columns -w # Suppress compiler warnings -Z number # Suppress warning number -z number # Set warning level
