This section includes seven complete real-library examples: BLAS, LAPACK, FFTPACK, MINPACK, BSPLINE-FORTRAN, libm, and TA-Lib. Each one provides build commands, Python usage, and numerical checks for its public routines.
The native-language boundary is deliberately explicit:
| Native language | Examples | What PRIK consumes |
|---|---|---|
| Fortran | BLAS, LAPACK, FFTPACK, MINPACK, BSPLINE-FORTRAN | Fortran source and interfaces, which the native build compiles and the wrapper exposes |
| C | libm, TA-Lib | Public C header declarations plus an already compiled library to link; implementation .c files are not wrapper inputs |
For libm, the declaration source is the platform's <math.h> and the linked
implementation is the platform math library. For TA-Lib, the declaration
source is its public ta_libc.h and the linked implementation is compiled
libta-lib.
The Real Libraries Portability workflow runs every example with Python 3.12 on Linux and macOS, using both x86-64/Intel and ARM64 runners. Compiler coverage differs by project:
| Library | Linux compiler coverage | macOS compiler coverage | Architectures |
|---|---|---|---|
| BLAS | GNU Fortran 13 + GCC 13 | GNU Fortran 13 + GNU GCC 13 | x86-64 and ARM64 |
| LAPACK | GNU Fortran 13 + GCC 13 | GNU Fortran 13 + GNU GCC 13 | x86-64 and ARM64 |
| FFTPACK | GNU Fortran 13 + GCC 13 | GNU Fortran 13 + GNU GCC 13 | x86-64 and ARM64 |
| MINPACK | GNU Fortran 13 + GCC 13 | GNU Fortran 13 + GNU GCC 13 | x86-64 and ARM64 |
| BSPLINE-FORTRAN | GNU Fortran 13 + GCC 13 | GNU Fortran 13 + GNU GCC 13 | x86-64 and ARM64 |
| libm | GCC 13 and Clang 18 | Apple Clang and GNU GCC 13 | x86-64/Intel and ARM64 |
| TA-Lib | GCC 13 | Apple Clang | x86-64/Intel and ARM64 |
The C compiler beside each Fortran compiler builds the generated Python binding. BLAS and LAPACK also receive their maintainer full-surface audits on Linux x86-64. Native Windows/MSVC is outside the current portability matrix.
For a smaller first workflow, start with one of the checked guides below. Each links to a complete source, build, import, or result path, rather than a draft-only recipe.
These examples build the supplied Fortran sources and generate bindings from their source-level declarations and interfaces.
| Goal | Page |
|---|---|
| Build and validate the complete Reference BLAS | BLAS wrapper |
| Build complete Reference LAPACK and validate 127 float64 routines | LAPACK wrapper |
| Wrap and validate all 31 FFTPACK procedures with NumPy and SciPy | FFTPACK wrapper |
| Wrap all 22 MINPACK procedures and use Python callbacks | MINPACK wrapper |
| Build and validate modern Fortran classes and 15 interpolation routines | BSPLINE-FORTRAN wrapper |
These examples obtain declarations from a public C header and link the generated extension to an existing compiled library. PRIK does not compile the library's implementation sources as part of the wrapper build.
| Goal | Page |
|---|---|
| Wrap 60 target-generated ISO C99 math routines from a system library | libm wrapper |
| Wrap and reference-check all 322 TA-Lib double and float-input indicators | TA-Lib wrapper |
For smaller introductory workflows, start with First Wrapped Function, First Wrapped Module, or the C support guide.
