BLT is a library of useful extensions for the Tcl language and the popular Tk graphical toolkit. It adds a vector and tree data type, background execution and some debugging tools to Tcl, and provides several new widgets for Tk, including graphs, bar-charts, trees, tabs, splines and hyper-links, as well as a new geometry manager, drag & drop support, and more. This package is a dummy package which depends on the current BLT library.

    2015-11-25 - Sergei Golovan <> blt (2.5.3+dfsg-3) unstable; urgency=medium * Added the autotools-dev build dependency to replace the outdated config.guess and config.sub by newer ones.

    2015-11-25 - Sergei Golovan <> blt (2.5.3+dfsg-2) unstable; urgency=medium * Fixed the distclean target in which fixes FTBFS when build twice in a row (closes: #791601). * Fixed the override_dh_installdoc target in debian/rules to fix FTBFS when dpkg-buildpackage -A is called for building the architecture- independent packages only (closes: #805999). * debian/patches/autoreconf.patch: fix autotools input for compatibility with recent autoconf. Thanks to Helmut Grohne <> and Steve Langasek <> (closes: #772590). * debian/patches/pkgindex.patch: correct this patch to patch the source, not the generated configure script. * debian/patches/install.patch: fix the distclean targets. * debian/patches/*: remove patching of autogenerated configure * Drop debian/rules override_dh_clean target, which gets it wrong.

    2014-11-21 - Sergei Golovan <> blt (2.5.3+dfsg-1) unstable; urgency=medium * Removed non-distributable files library/dd_protocols/* from the source package (closes: #769814). * Split out the tk8.6-blt2.5 package to reflect the changed library soname. The 8.6 suffix is added because this package works only with Tcl/Tk 8.6. Added breaks header with all packages dependent on blt which included the previous library soname. This prevents partial upgrades (closes: #751767). * Bumped the standards version to 3.9.6.

    2014-07-09 - Sergei Golovan <> blt (2.5.3-4) unstable; urgency=medium * Made blt-dev replace blt (<< 2.5) because the doc-base file is moved to the former package from the latter. * Added patch which fixes BLT stubs declaration. * Added a few patches which eliminate GCC warnings about incompatible pointer types, using possibly unitialized variables, unused variables and casts to/from pointer from/to integer of different size. This fixes a few segfaults in demos (but not all of them).

    2014-07-06 - Sergei Golovan <> blt (2.5.3-3) unstable; urgency=medium * Added missing headers to bltNsUtil.c to fix build failures on 64bit architectures.

    2014-07-04 - Sergei Golovan <> blt (2.5.3-2) unstable; urgency=medium * Restored forgotten call to dh_autotools-dev_updateconfig and explicitly supplied --host option to the configure call to build the package on kfreebsd-* architectures.

    2014-07-04 - Sergei Golovan <> blt (2.5.3-1) unstable; urgency=low * New maintainer Sergei Golovan (closes: #664092). * New upstream and new upstream release. * Reviewed and refreshed patches. * Added a patch from the FreeBSD BLT port. It allows BLT to work when it's built with Tcl/Tk 8.6 (closes: #753476). * Moved HTML documentation from blt to blt-dev.

    2014-06-13 - Matthias Klose <> blt (2.4z-9) unstable; urgency=high * QA upload. * Build using Tcl/Tk 8.6.

    2014-04-16 - Sergei Golovan <> blt (2.4z-8) unstable; urgency=low * QA upload. * Fixed build with newer Tcl/Tk package which switched from shlibs to symbols. (Closes: #724882)
