SWIG-4.1.1

Introduction to SWIG

SWIG (Simplified Wrapper and Interface Generator) is a compiler that integrates C and C++ with languages including Perl, Python, Tcl, Ruby, PHP, Java, C#, D, Go, Lua, Octave, R, Scheme, and Ocaml. SWIG can also export its parse tree into Lisp s-expressions and XML.

SWIG reads annotated C/C++ header files and creates wrapper code (glue code) in order to make the corresponding C/C++ libraries available to the listed languages, or to extend C/C++ programs with a scripting language.

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Package Information

  • Download MD5 sum: c7d55a1bca26752f3846c85b43c1a69c

  • Download size: 8.2 MB

  • Estimated disk space required: 82 MB (2.1 GB with tests)

  • Estimated build time: 0.1 SBU (add 7.8 SBU for tests; both using parallelism=4)

SWIG Dependencies

Required

pcre2-10.42

Optional

Boost-1.83.0 for tests, and any of the languages mentioned in the introduction, as run-time dependencies

Installation of SWIG

Install SWIG by running the following commands:

./configure --prefix=/usr                      \
            --without-javascript               \
            --without-maximum-compile-warnings &&
make

To test the results, issue: PY3=1 make -k check TCL_INCLUDE=. The unsetting of the variable TCL_INCLUDE is necessary since it is not correctly set by configure. The tests are only executed for the languages installed on your machine, so the disk space and SBU values given for the tests may vary, and should be considered as mere orders of magnitude. According to SWIG's documentation, the failure of some tests should not be considered harmful. The go tests are buggy and may generate a lot of meaningless output.

Now, as the root user:

make install &&
install -v -m755 -d /usr/share/doc/swig-4.1.1 &&
cp -v -R Doc/* /usr/share/doc/swig-4.1.1

Command Explanations

--without-maximum-compile-warnings: disables compiler ansi conformance enforcement, which triggers errors in the Lua headers (starting with Lua 5.3).

--without-<language>: allows disabling the building of tests and examples for <language>, but all the languages capabilities of SWIG are always built.

Short Descriptions

swig

takes an interface file containing C/C++ declarations and SWIG special instructions, and generates the corresponding wrapper code needed to build extension modules

ccache-swig

is a compiler cache, which speeds up re-compilation of C/C++/SWIG code
