cygipc and cygutils have some incompatibilities with cygwin-1.5.7; this updated version resolves those conflicts. Note that you will probably need to re-install cygwin-1.5.7 after upgrading cygipc -- this is an unfortunate consequence of the pre-existing conflict between cygipc-[OLDVERSION] and cygwin-1.5.6+.
A list of the specific changes ( for both cygipc-2.03-2 and cygutils-1.2.4-1 ) appears below. This is, in all likelihood, the LAST release of cygipc. The cygserver implementation now shipped with cygwin-1.5.7 and later is a much better, and better-supported, implementation; all existing packages which rely on cygipc should begin transitioning to cygserver. For package maintainers and developers, this will probably boil down to, in most case, simply: (a) recompiling, (b) installing and running the cygserver daemon, (c) changing documentation, and (d) getting used to answering new questions from your users about "what happened to cygipc" <g> ==== 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. Then, run setup and answer all of the questions. !!!!!! NOTE: you will need to run setup TWICE. First, update/install cygipc-2.03-1 and cygutils-1.2.4-1. Let setup run to completion. Then, run setup AGAIN -- and this time, choose "reinstall" for cygwin-1.5.7 (or whatever is your current version of the cygwin package). !!!!!!

IF (and only if) /usr/include/sys/ipc.h and friends do not exist, then a postinstall script creates symlinks to the cygipc versions. This means if you really want to be sure that you're compiling/linking against cygipc, you need to add -I/usr/include/cygipc to your compile command. 3) cygutils no longer provides ipcs or ipcrm, as (a) cygipc now provides cygipc-based versions, and (b) cygwin itself provides cygserver-based versions. 4) cygutils provides cygserver-based versions of semtool msgtool shmtool semstat 5) cygutils provides 'ipck' and 'ipckcygipc' -- a useful shell script for checking on/killing IPC objects. Obviously, one uses the cygserver tools, the other uses the cygipc tools. 6) Cygipc will be going into deep freeze -- still supported for legacy applications, but all applications are highly encouraged to switch to the FAR better implementation provided by cygserver. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
