Numerical libraries for FreeFEM

Contains well-known numerical libraries compiled in Javascript for FreeFEM. Generating Javascript output requires cross-compiling, which is not usually provided in the building procedure of these libraries. This Makefile generates the required cross-compilation directives and produces a single Javascript lib.

The main target is emscripten, but other compilers can be used by setting $(CXX) and $(CXXFLAGS). The three main binary output formats are dev (development version), min (optimized for speed and minimum size) and native. Please refer to ffjs for more details. Optimized options are available (mainly “-Os”), but without compromising on portability.

With many thanks to the projects used here:

• f2c
• BLAS
• CBLAS
• LAPACK
• ARPACK
• SuiteSparse
• TetGen

This library has been initiated as a tool for ffjs and FreeFEM-cs but it can be used standalone. More packages may be added on request.

Build commands

Building the default (native) binary version (result in bin_default/libfflib.a):

make -j binary

Creating binaries for any architecture named “arch” (result in bin_arch/libfflib.a):

make -j BINTAG=arch BINGOAL=all

All the usual make variables (CXX, CXXFLAGS, etc) are available. Please refer to the ffjs project for Javascript configuration options.
