during configure() swig is looking for many external libraries/programs, the support should be enabled conditionally with USE flags, or disabled by default: Optional Packages: --with-PACKAGE[=ARG] use PACKAGE [ARG=yes] --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no) --without-maximum-compile-warnings Disable maximum warning verbosity --without-pcre Disable support for regular expressions using PCRE2 --with-pcre2-prefix=PREFIX Prefix where pcre2 is installed (optional) --with-pcre2-exec-prefix=EPREFIX Exec prefix where pcre2 is installed (optional) --with-boost[=ARG] use Boost library from a standard location (ARG=yes), from the specified location (ARG=<path>), or disable it (ARG=no) [ARG=yes] --with-boost-libdir=LIB_DIR Force given directory for boost libraries. Note that this will override library path detection, so use this parameter only if default library detection fails and you know exactly where your boost libraries are located. --with-libm=STRING math library --with-libc=STRING C library --without-alllang Disable all languages --without-android Disable Android --with-android=path Set location of android executable --with-adb=path Set location of adb executable - Android Debug Bridge --with-ant=path Set location of ant executable for Android --with-ndk-build=path Set location of Android ndk-build executable --without-csharp Disable CSharp --with-cil-interpreter=path Set location of CIL interpreter for CSharp --with-csharp-compiler=path Set location of CSharp compiler --without-d Disable D --with-d2-compiler=path Set location of D2 compiler (DMD compatible) --without-go Disable Go --with-go=path Set location of Go compiler --without-guile Disable Guile --with-guile-config=path Set location of guile-config --with-guile=path Set location of Guile executable --with-guile-cflags=cflags Set cflags required to compile against Guile --with-guile-libs=ldflags Set ldflags needed to link with Guile --without-java Disable Java --with-java=path Set location of java executable --with-javac=path Set location of javac executable --with-javaincl=path Set location of Java include directory --without-javascript Disable Javascript --with-jscoreinc=path Set location of JavaScriptCore/Webkit include directory --with-jscorelib=path Set location of the JavaScriptCore/Webkit library directory --with-jsv8inc=path Set location of Javascript v8 include directory --with-jsv8lib=path Set location of V8 Javascript library directory --without-lua Disable Lua --with-lua=path Set location of Lua executable --with-luaincl=path Set location of Lua include directory --with-lualib=path Set location of Lua library directory --without-mzscheme Disable MzScheme --with-mzscheme=path Set location of MzScheme executable --with-mzc=path Set location of MzScheme's mzc --without-ocaml Disable OCaml --with-ocamlc=path Set location of ocamlc executable --with-ocamldlgen=path Set location of ocamldlgen --with-ocamlfind=path Set location of ocamlfind --with-ocamlmktop=path Set location of ocamlmktop executable --with-camlp4=path Set location of camlp4 executable --without-octave Disable Octave --with-octave=path Set location of Octave executable --without-perl5 Disable Perl5 --with-perl5=path Set location of Perl5 executable --without-php Disable PHP --with-php=path Set location of PHP executable --without-python Don't probe for Python 2.x --with-python=path Set location of Python 2.x executable --without-python3 Don't probe for Python 3.x --with-python3=path Set location of Python 3.x executable --without-r Disable R --with-r=path Set location of R executable (r) --without-ruby Disable Ruby --with-ruby=path Set location of Ruby executable --without-scilab Disable Scilab --with-scilab=path Set location of Scilab executable --with-scilab-inc=path Set location of Scilab include directory --without-tcl Disable Tcl --with-tclconfig=path Set location of tclConfig.sh --with-tcl=path Set location of Tcl package --with-tclincl=path Set location of Tcl include directory --with-tcllib=path Set location of Tcl library directory --with-swiglibdir=DIR Put SWIG system-independent libraries into DIR.
