This release is placed into "gs-VSN/priv/tcl" and the +'gstk_port_handler' module searches this directory first to find the +"wish" executable program. + +It is possible to pack the files from a standard installation on a +machine into a TAR file but it is preferable to build Tcl/Tk from +sources. The steps are + + 0. Set some environment variables + + % setenv BUILDDIR /tmp/build + % setenv GNUTAR gtar + + 1. Download unpack the sources from http://sourceforge.net/projects/tcl. + Use the latest stable release. When this README was written + the latest stable version was 8.3.4. + + % mkdir -p $BUILDDIR/tcl + % cd $BUILDDIR + % $GNUTAR -xzf /my/src/path/tcl8.3.4.tar.gz + % $GNUTAR -xzf /my/src/path/tk8.3.4.tar.gz + + % cd tcl8.3.4/unix + % ./configure --enable-gcc --enable-threads --disable-load \ + --disable-shared --prefix=$BUILDDIR/tcl + % make + % make install + + % cd ../../tk8.3.4/unix + % ./configure --enable-gcc --enable-threads --disable-load \ + --disable-shared --prefix=$BUILDDIR/tcl \ + --with-tcl=$BUILDDIR/tcl/lib + % make + % make install + + 2. Check that the executable wish program don't depend on libtcl + or libtk. If it does we have to redo this or keep them + where they are, else we can remove the libraries + + % cd $BUILDDIR + % ldd tcl/bin/wish8.3 + + and if the executables doesn't depend on libtcl or libtk we remove them + + % rm -f tcl/lib/libt* + + 3. Remove other things we don't need. There may be other things in + later releases but only remove the obvious things + + % rm -fr tcl/include tcl/man + % rm -f tcl/bin/tclsh* + % rm -f tcl/lib/*.sh + % rm -fr tcl/lib/tcl*/http* + % rm -fr tcl/lib/tcl*/tcltest* + % rm -fr tcl/lib/tk*/demos + % rm -fr tcl/lib/tk*/images + % rm -f tcl/lib/*/*.c + + 4. Some releases of Tcl/Tk contains soft links that make the directory + structure circular making it impossible to use 'cp' to copy the + tcl directory. You can find them with + + % find tcl -type l + + 5. Find out the name of the resulting TAR archive. Run the GS configure + script on the target platform to view the name + + % cd $ERL_TOP/lib/gs + % rm -f config.cache + % autoconf + % ./configure + + 6. Use the TAR program on the system to pack the resulting Tcl/Tk + distribution. Keep the top "tcl" library + + % tar -cf - tcl | gzip > xxxxxxxx.tar.gz + + 7. Copy and check in this TAR archive into the directory + + /clearcase/otp/erts/lib/gs/tcl/binaries + + 8. We are done........ + + +Windows +------- + +These instructions are aimed at the 8.5.7 release of both tcl and tk, +but should work for 8.4 as well as 8.6 releases with appropriate +modifications. + +0. Download the source tar files for both tcl and tk and unpack the +tar files from the same root. + +1. Start with tcl. Open a command prompt with the appropriate Visual +C++ command environment (there is usually a shortcut under VC++ tools +or something in the start menu. With this command prompt, cd to the +tcl<version>/win directory and issue the following commands: + +dos_prompt> nmake -f makefile.vc OPTS=static INSTALLDIR=<some temp dir>\tcl +... +dos_prompt> nmake -f makefile.vc OPTS=static INSTALLDIR=<some temp dir>\tcl install + +2. Move further to tk. Using the same command prompt, cd +..\..\tk<version>\win and build there: + +dos_prompt> nmake -f makefile.vc OPTS=static TCLDIR=<top dir of sources>\tcl<version> INSTALLDIR=<some temp dir>\tcl +... +dos_prompt> nmake -f makefile.vc OPTS=static TCLDIR=<top dir of sources>\tcl<version> INSTALLDIR=<some temp dir>\tcl install + +3. Now you will need to strip the installation you put in <some temp +dir>\tcl. To do this, you will want a more appropriate command +shell. Start cygwin bash and cd to the cygwin equivalent of <some temp +dir>, i.e. where tcl/tk was installed. Now clean away what's not +needed (this is not optional, gs won't work with a full version...) + + % rm -fr tcl/include tcl/man + % rm -f tcl/bin/tclsh* + % rm -f tcl/lib/*.sh + % rm -fr tcl/lib/tcl*/http* + % rm -fr tcl/lib/tcl*/tcltest* + % rm -fr tcl/lib/tcl*/tzdata + % rm -fr tcl/lib/tcl*/msgs + % rm -fr tcl/lib/tk*/demos + % rm -fr tcl/lib/tk*/images + % rm -fr tcl/lib/tk*/tzdata + % rm -f tcl/lib/*/*.c + % rm -f tcl/lib/*.lib + % rm -fr tcl/lib/tcl8 + +(The last line is especially important, gs will crash otherwise...) + +4. Now copy license.terms from the sources, otherwise you may break the redistribution policy. + + % cp <top of sources/tcl<version>/license.terms tcl/ + +5. Pack the tar file: + + % tar zcf win32.tar.gz tcl + +6. Put it in $ERL_TOP/lib/gs/tcl/binaries (as described for Unixes) + +7. You are done! + + + |
