To compile 'tcltklib', you must have Tcl/Tk libraries on your environment. Although 'extconf.rb' script searches Tcl/Tk libraries and header files (as default, searches tclConfig.sh/tkConfig.sh and use the defintions on those; ActiveTcl has high priority on searching unless --without-ActiveTcl), sometimes fails to find them. And then, 'tcltklib' cannot be compiled. If Tcl/Tk libraries or header files are installed but are not found, you can give the information by arguments of the 'configure' script. Please give some or all of the following options. --with-tk-old-extconf use old "extconf.rb" (default: false). If current extconf.rb doesn't work properly (or your install process is based on old documant about Ruby/Tk install), please try this option. --with-ActiveTcl / --without-ActiveTcl --with-ActiveTcl= search ActiveTcl libraries (default: true). When true, try to find installed ActiveTcl. When is given, use it as the ActiveTcl's top directory (use /lib, and so on). Old "extconf.rb" doesn't support this option. --with-tk-shlib-search-path= teach the paths for loading shared-libraries to linker. is a path list with the same format as PATH environment variable. This option may be experimental. Old "extconf.rb" doesn't support this option. --with-tcltkversion= --with-tcltkversion=, force version of Tcl/Tk libaray (e.g. libtcl8.4g.so & libtk8.4g.so ==> --with-tcltkversion=8.4g libtcl8.4.so & libtk8.4g.so ==> --with-tcltkversion=8.4,8.4g) --enable-tcl-h-ver-check/--disable-tcl-h-ver-check --enable-tk-h-ver-check/--disable-tk-h-ver-check enable or disable for checking MAJOR_VERSION and MINOR_VERSION on tcl.h/tk.h whether match with Tcl/Tk libraries' version or not. --with-tcl-build-dir= --with-tk-build-dir= If you want to compile with libraries on Tcl/Tk build dir (still NOT installed), you must use these options. (e.g. --with-tcl-build-dir=./build/tcl8.5.9/unix) When use these options, --with-tclConfig-dir and --with-tkConfig-dir options are ignored (however, --with-tclConfig-file and --with-tkConfig-file options are still available). --with-tclConfig-file=/--without-tclConfig-file --with-tkConfig-file=/--without-tkConfig-file file path of tclConfig.sh/tkConfig.sh, or don't refer those. If you want use non-standard filenames of config files (e.g. tclConfig-static.sh), you must use these options. --with-tclConfig-dir= --with-tkConfig-dir= the directory contains 'tclConfig.sh' and 'tkConfig.sh'. Current "extconf.rb" uses the information on tclConfig.sh/tkConfig.rb, if possible. Old "extconf.rb" doesn't support this option. --with-tcllib= (e.g. libtcl8.4.so ==> --with-tcllib=tcl8.4) --with-tklib= (e.g. libtk8.4.so ==> --with-tklib=tk8.4) --enable-tcltk-stubs (if you force to enable stubs) On old "extconf.rb", default is false. On current "extconf.rb", default is true when tclConfig.sh/tkConfig.sh have TCL_STUB_LIB_SPEC /TK_STUB_LIB_SPEC, else default is false. --with-tcl-dir= equal to "--with-tcl-include=/include --with-tcl-lib=/lib" --with-tk-dir= equal to "--with-tk-include=/include --with-tk-lib=/lib" --with-tcl-include= the directry contains 'tcl.h' --with-tk-include= the directry contains 'tk.h' --with-tcl-lib= the directry contains 'libtcl.so' --with-tk-lib= the directry contains 'libtk.so' --enable-mac-tcltk-framework (MacOS X) use Tcl/Tk framework (Obsolete. Please use '--enable-tcltk-framework'.) --enable-tcltk-framework use Tcl/Tk framework --with-tcltk-framework= the directory contains Tcl/Tk framework; "/Tcl.framework" and "/Tk.framework". When this option is given, it is assumed that --enable-tcltk-framework option is given also. --with-tcl-framework-dir= Tcl framework directory (e.g. "/Library/Frameworks/Tcl.framework") --with-tk-framework-dir= Tk framework directory (e.g. "/Library/Frameworks/Tk.framework") --with-tcl-framework-header= Tcl framework headers directory (e.g. "/Library/Frameworks/Tcl.framework/Headers") --with-tk-framework-header= Tk framework headers directory (e.g. "/Library/Frameworks/Tk.framework/Headers") --with-X11 / --without-X11 use / not use the X Window System --with-X11-dir= equal to "--with-X11-include=/include --with-X11-lib=/lib" --with-X11-include= the directry contais X11 header files --with-X11-lib= the directry contais X11 libraries If you forgot to give the options when do 'configure' on toplevel directry of Ruby sources, please try something like as the followings. $ cd ext/tcltklib $ rm Makefile $ CONFIGURE_ARGS='--with-tcl-include=/usr/local/include/tcl8.4/ --with-tcllib=tcl8.4 --with-tklib=tk8.4' ruby extconf.rb *** ATTENTION *** When your Tcl/Tk libraries are compiled with "pthread support", Ruby/Tk may cause "Hang-up" or "Segmentation Fault" frequently. If you have such a trouble, please try to use the '--enable-pthread' option of the 'configure' command and re-compile Ruby sources. It may help you to avoid this trouble. The following configure options may be useful. --enable-tcl-thread/--disable-tcl-thread --with-tclConfig-file= --with-tkConfig-file= It is not need that 'tclConfig.sh' is a normal Tcl/Tk's tclConfig.sh. But the file is expected to include the line "TCL_THREADS=0" or "...=1". When no "TCL_THREADS=?" line, if Tcl version is 7.x or 8.0 which is given by "TCL_MAJOR_VERSION=?" line and "TCL_MINOR_VERSION=?" line, then --disable-tcl-thread is expected. Else, ignore the 'tclConfig.sh'. If --enable-tcl-thread or --disable-tcl-thread option is given, then --with-tclConfig-file option is ignored. ========================================================== Hidetoshi NAGAI (nagai@ai.kyutech.ac.jp)
