CHANGES (since 1.0.2-1) (a) changed to 'auto-import' build style. This is the last of my packages that previously needed '-DFOO_STATIC' flags when linking client programs statically. (b) Because I'm not sure if this DLL is absolutely backwards compatible, it has been renamed (from cygbz21.0.dll to cygbz2-1.dll) (c) This new DLL is in a new package, so that it can coexist with the old one. The new package is 'libbz2_1', the old package is 'libbz2_0'. See the NOTES section ath the bottom of this email. CHANGES (since 1.0.1-3) (a) updated to 1.0.2 source, which has many bugfixes discovered over the 18 months since 1.0.1 was released. (b) splits binary package into 'libbz2_0' and 'bzip2'. The former contains the DLL alone; the latter contains everything else. (c) 1.0.2 contains several wrapper scripts and man pages: bzgrep, bzdiff, bzmore (d) cygwin package now has a postinstall script to handle the info files (e) Reorganized to allow automated building (only maintainers care about this) (f) You STILL need to worry about the -DBZLIB_STATIC flag with this release. That will be improved in future releases, but not yet. See the NOTES section, below. --Chuck Wilson INSTALLATION: To update your installation, click on the "Install Cygwin now" link on the http://cygwin.com/ web page. This downloads setup.exe to your system. Save it and run setup, answer the questions and pick up 'bzip2' from the 'Utils' category. You may need to click the "Full" button if it doesn't show up. You might want to make sure you update/install BOTH of the following packages: bzip2-1.0.2-2 libbz2_1-1.0.2-2 Note that downloads from sources.redhat.com (aka cygwin.com) aren't allowed due to bandwidth limitations. This means that you will need to find a mirror which has this update. In the US, ftp://mirrors.rcn.net/mirrors/sources.redhat.com/cygwin/ is a reliable high bandwidth connection. In Japan, ftp://ftp.u-aizu.ac.jp/pub/gnu/gnu-win32/ is usually up-to-date In DK, http://mirrors.sunsite.dk/cygwin/ is usually up-to-date. If one of the above doesn't have the latest version of this package you can either wait for the site to be updated or find another mirror.

This includes ideas and comments about the setup utility or Cygwin in general. If you want to make a point or ask a question the Cygwin mailing list is the appropriate place. *** CYGWIN-ANNOUNCE UNSUBSCRIBE INFO *** To unsubscribe to the cygwin-announce mailing list, look at the "List-Unsubscribe: " tag in the email header of this message.

This means you no longer need "-DBZLIB_STATIC" or even -DALL_STATIC when compiling objects intended for static linking. Just compile as normal. HOWEVER, you need to use a special flags when linking statically: 'gcc -static'. For dynamic linking, you need no special link-time flags (assuming you're using binutils newer than 20011002, when --enable-auto-import was made the default). -- PRO: no compile time flags needed when building client programs; ONLY need a link-time flag linking to static libraries. NO special flags at compile-time nor link-time when linking to dynamic links. -- CON: (partial): if using binutils older than 20010930, you now need a special linktime flag for dynamic linking (-Wl,--enable-auto-import). However, with an up-to-date binutils, you don't need this. o If you are building a package that depends on libbz2, and you wish to link *statically*, just use 'gcc -static' when linking your package. There no need to -Ddefine anything special when compiling your object files. o No special -Ddefine options or link options are needed when building a package that depends on libbz2 and you want to link dynamically (recommended). o The following packages have been converted from old style "-DFOO_STATIC" to the new autoimport style of DLL structure: ncurses readline gettext zlib tiff libpng xpm-nox jpeg jbig gdbm bzip2 The following have not (yet) been converted, and still need -DFOO_STATIC for static builds: NONE!!!!!
