This will build a Tclkit named "tclkit-" or a KitDLL named "libtclkit.so". --------------- Using This Tool --------------- Usage: kitcreator [{build | retry | clean | distclean}] [{ | cvs_ | fossil_}] [ ...] Where: version is a Tcl version number (e.g., 8.6.1) tag is a CVS or fossil release tag (e.g., HEAD) configure_option option to pass to subordinate configure scripts (e.g., --enable-64bit) Default is to create a Tclkit from Tcl version 8.6.1 Examples: 1. Create a Tclkit: a. $ ./kitcreator 2. Create a Tclkit for Tcl 8.5.15: a. $ ./kitcreator 8.5.15 3. Create a Tclkit for Tcl from CVS HEAD: a. $ ./kitcreator cvs_HEAD 4. Compile a 64-bit Tclkit: a. $ ./kitcreator --enable-64bit 5. Cross-compile a Tclkit: a. Bootstrap (optional, you can use an existing Tclkit): i. $ ./kitcreator ii. $ mv tclkit-8.4.19 tclkit-local iii. $ TCLKIT="`pwd`/tclkit-local" iv. $ export TCLKIT b. Cross-compile: i. $ CC=mipsel-linux-uclibc-gcc ii. $ CXX=false iii. $ AR=mipsel-linux-uclibc-ar iv. $ RANLIB=mipsel-linux-uclibc-ranlib v. $ export CC CXX AR RANLIB vi. $ ./kitcreator --host=mipsel-linux-uclibc Note: When cross-compiling, the Tcl configure script may be unable to determine which serial support method to use. If you want serial support in a cross-compiled tclkit, specify it manually, e.g.: $ ./kitcreator CFLAGS=-DUSE_TERMIOS=1 -host=mipsel-linux-uclibc 6. Compile a 64-bit Tclkit 8.5.15 using SunStudio 12.1 on Solaris/x86: a. $ CC='/opt/sunstudio12.1/bin/cc -m64' b. $ CXX='/opt/sunstudio12.1/bin/CC -m64' c. $ PATCH='gpatch' c. $ export CC CXX PATCH d. $ ./kitcreator 8.5.15 --enable-64bit 7. To clean up post-build: a. $ ./kitcreator clean 8. Create a Tclkit without Metakit4 support (falls back to Zip for storage): a. KITCREATOR_PKGS='tk itcl' b. export KITCREATOR_PKGS c. ./kitcreator 9. Create a Tclkit with Metakit4 support, but using Zip for storage: a. $ ./kitcreator --enable-kit-storage=zip 10. Create a Tclkit with Metakit4 support, but using C-VFS for storage a. $ ./kitcreator --enable-kit-storage=cvfs 11. Create a KitDLL without Metakit support (will not create a Tclkit binary, just the library): a. $ KITCREATOR_PKGS='tk itcl kitdll' b. $ export KITCREATOR_PKGS c. $ ./kitcreator Environment variables: 1. MAKE Specifies the tool you wish to be called to build targets from a Makefile. This script is generally more well tested with GNU Make. 2. PATCH Specifies the tool you wish to be called to apply unified diff patches. This script is generally more well tested with GNU Patch. 3. TCLKIT Specify the path to a Tclkit that is runnable on the current system. The default is "tclkit". A working tclkit is required for cross-compiling Tclkits. 4. STATICTK Specify this as "1" to statically link to Tk. The default action on most platforms is to dynamically link to Tk. When building KitDLL, STATICTK is "1" by default. If you want to enable dynamic linking of Tk with KitDLL you will have to specify this as "-1". 5. STATICMK4 Specify this as "0" to attempt to create create the "mk4tcl" project as a shared object. If this fails, it will fall back to building statically. Specify it as "-1" to force building it as a shared object. Any other value, including being unset results in "mk4tcl" being built and linked statically. KitDILL sets this to variable to "0". If Metakit4 is built shared, it cannot be used for the kit storage for Tclkit. 6. STRIP Specifies the tool you wish to be called to strip object files, archives, and shared objects. The default is "strip". You should probably set this if you are cross-compiling. 7. KITCREATOR_PKGS Specify which non-required packages to build. The default list is: tk itcl mk4tcl If mk4tcl is not present a Zip-based storage mechanism will be used instead. To specify that the default be used, do not set this or set it to the empty string. To specify that no non-required packages be built, set it to a string that contains only white space. If "kitdll" is specified in the list the target becomes KitDLL and no Tclkit will built, but instead libtclkit. 8. KITCREATOR_MINENCODINGS Set this variable to a non-empty string to generate a Tclkit without all encodings, only including the following: ascii.enc cp1252.enc iso8859-1.enc iso8859-15.enc iso8859-2.enc koi8-r.enc macRoman.enc 9. KITCREATOR_MINBUILD Set this variable to a non-empty string to exclude unnecessary packages from Tcl build. This excludes the following packages: tcltest Additionally, any bundled packages (in the "pkgs" directory) are excluded. This typically includes (as of Tcl 8.6): itcl thread Cross compiling Environment Variables: 1. CC C compiler e.g. i686-pc-mingw32-gcc 2. CXX C++ compiler. Required if you want to use mk4tcl. e.g. i686-pc-mingw32-g++ If not required, you can set it to the string "false" 3. AR Library creator e.g. i686-pc-mingw32-ar 4. RANLIB Library post processing executable e.g. i686-pc-mingw32-ranlib 5. STRIP Executable name to strip binaries e.g. i686-pc-mingw32-strip 6. NM Executable used to dump names from the objects e.g. i686-pc-mingw32-nm 7. CC_FOR_BUILD, HOST_CC Set this to the name of compiler on the host on which the cross compilation is being run. On Windows we also need this: 1. RC Resource compiler : e.g. i686-pc-mingw32-windres Kitsh Configure Options: 1. --enable-kit-storage={zip|mk4|auto} Specify which type of storage to use with the Tclkit. The default is to auto-detect. Auto-detection uses Mk4 if available and built statically, otherwise it falls back to Zip. -------------------- Using the KitDLL SDK -------------------- When you build a KitDLL, a "libtclkit-sdk-.tar.gz" tarball is also produced. This tarball contains the Tcl (and Tk, if compiled) stubs libraries, and Tcl (and Tk, if compiled) header files needed to compile and link things against Tcl (and Tk). It also includes "tclConfig.sh" (and "tkConfig.sh", if Tk was compiled). The purpose for this tarball is to be used to build Tcl extensions or applications that rely on Tcl/Tk using the KitDLL. To use it, one first must extract the tarball. After that the environment variable "TCLKIT_SDK_DIR" must be set to the directory that was created in order to make most of the variables contain useful values. For example, to build an extension using the KitDLL SDK one would typically do something like: 1. Compile KitDLL (may be omitted if the KitDLL SDK is already available) a. $ KITCREATOR_PKGS='tk itcl kitdll' b. $ export KITCREATOR_PKGS c. $ ./kitcreator 2. Compile the Extension a. $ tar -xf /path/to/libtclkit-sdk-8.4.19.tar.gz b. $ TCLKIT_SDK_DIR="$(pwd)/libtclkit-sdk-8.4.19" c. $ export TCLKIT_SDK_DIR d. $ ./configure --with-tcl="${TCLKIT_SDK_DIR}/lib" e. $ make ------------------- Method of Operation ------------------- Summary: 1. "kitcreator" calls */build.sh 2. */build.sh downloads and compiles appropriate software 3. */build.sh installs software into "inst" (run-time + compile-time) 4. */build.sh installs run-time software into "out", this will be included in the Tclkit as if it were the root directory of the Tclkit (combined with other "out" directories) 5. kitsh/build.sh compiles a "main" function and links all the built libraries together into an executable 6. kitsh/build.sh combines all the "out" directories into one 7. kitsh/build.sh creates a Metakit or Zip database from the combined directories and appends that to the compiled executable using: a. A Tclkit found in the environment variable "TCLKIT" (tclkit if unset) if it is functional; or b. The built kit itself (does not work for cross-compiling) Details: The general mechanism that enables a Tclkit to operate is a small Tcl initialization routine linked statically to the core libraries needed to operate a Tcl interpreter, the Tcl VFS Layer, and a database-backed (Metakit) Virtual File System that is appended to the end of the executable. This project brings together all of the required pieces, plus some additional pieces that were found in the original Tclkit: 1. Tk (dynamically linked) 2. Itcl (dynamically linked) The source code for these pieces are downloaded, compiled, and linked, and the database containing the appropriate filesystem data is created. What sets this project apart from other similar projects is that: 1. It attempts to be modular; 2. It supports cross-compiling; 3. It downloads the source from their original repositories; 4. It allows you to specify an arbitrary version of Tcl (including CVS); and 5. It uses GNU Autoconf scripts for compiling the part of the Tclkit that brings the whole thing together (the Kitsh) To accomplish these goals the following mechanisms are in place: 1. The top-level "kitcreator" script; and 2. Per-project subdirectories, each containing a "build.sh" script The top-level "kitcreator" script is very simple. Its only job is to interpret command line arguments, and call the per-project "build.sh" scripts. For the "tcl" project it also finds the appropriate "tclConfig.sh" (and stores this path in TCLCONFIGDIR) to enable subsequent build scripts to find the appropriate Tcl to link against. The per-project "build.sh" scripts are entirely autonomous. They are responsible for downloading the source code for the appropriate version that will compile and link against the current version of Tcl (user requested version can be found in "TCLVERS", while the actual version must be requested from the "tclConfig.sh" script), compiling it, installing a functional copy into the per-project "inst" directory, and installing anything that needs to be in the Tclkit's VFS root into the per-project "out" directory. Any additional projects can be included simply by creating the appropriate directory in the same directory as the "kitcreator" script, creating a "build.sh" script in that directory that follows the above procedure, and then referencing that directory in "KITCREATOR_PKGS" for the "kitcreator" invocation. In this way KitCreator is "pluggable". Included packages may be either statically or dynamically linked. If it is statically linked then the module name must be the name of the directory -- that is, if the directory were "foo", KitCreator will expect to initialize the module statically using Foo_Init(). The exception to this is the "kitsh" project. It is the glue that binds all the individual projects together into a single executable. Its build script does not create an "inst" or an "out" directory because it is not a library. Instead, it collects all the other project's "out" directories into a single directory (starpack.vfs), as well a static file (boot.tcl). It then compiles the source code, and then installs the VFS onto the resulting executable. The VFS is created by the "installvfs.tcl" script for Kitsh. For KitDLL the VFS is created by "dir2c.tcl". If the "mk4tcl" project fails to build (or is not requested to be built), the rest of the project will be built using zip files instead of Metakit databases. To create the storage database, one of two Tclkits is used (tried in this order): 1. The Tclkit specified by the TCLKIT environment variable (or "tclkit" if that variable is not set) if it is functional; or 2. The built Tclkit itself The second method will not work if the built Tclkit is not executable on the current platform (i.e., in the case of cross-compilation) and so it may be necessary to bootstrap a runnable Tclkit first. KitDLL mounts the VFS for every interpreter that calls Tcl_Init(). The system VFS that is created at build time is mounted at /.KITDLL_TCL. Additionally, if there is a ZIP file appended to the DLL it will be mounted at /.KITDLL_USER and if there is a ZIP file appended to the executable it will be mounted at /.KITDLL_APP. All VFSes that are mounted have the "lib" sub-directory appended to the interpreters "auto_path" variable.
