I have just uploaded an updated GCC-4 package to cygwin.com. It will be arriving at your favourite mirror next time it synchronizes itself with the official Cygwin repository. With this release, the compiler moves out of experimental status and becomes the default compiler for the distribution. The Java and Ada compilers are known to have some bugs, but the core compiler and primary languages (C, C++ and Fortran) are all working well enough to be considered stable, conformant to the relevant language specs, and production-ready. **** IMPORTANT NOTE ON THE ALTERNATIVES SYSTEM: The alternatives system (see 'man alternatives') is used with this package to select the default system compiler that is invoked under the plain 'gcc' (or 'g++', etc.) name without any -3 or -4 suffix. With this release, the default system compiler, which was previously gcc-3, is now switched to gcc-4 for the first time. All future distro packages will be built with this compiler, and indeed many already have been for some time, so no significant disruption should arise. However, for those who would prefer to retain gcc-3 as their system default compiler, it is easy to change the alternatives selection. Generally, you should switch all the compiler packages simultaneously to either -3 or -4 versions; mixed usages aren't guaranteed to work. To this end, two shell scripts are installed by this release: /usr/bin/set-gcc-default-3.sh /usr/bin/set-gcc-default-4.sh These can be invoked to switch all the alternatives for the compiler en masse. Note that not all language compilers exist in both -3 and -4 versions; fortran changes names between the two versions, so doesn't clash, and D and Pascal only exist in -3 versions currently. **** IMPORTANT NOTE FOR GNAT USERS: The GNAT tools do not understand the version-suffix system used by the other gcc compilers in the package. If you attempt to invoke gnatmake-4, for example, it will attempt to invoke plain unsuffixed names like "gnatchop", "gnatbind" as subexecutables. In consequence, only the currently-selected version of gnat chosen by the alternatives system can run correctly at any given time; you should always configure the GNAT alternatives to select as default the version you wish to use, by invoking one of the two scripts mentioned above. **** COMING NEXT: The to-do list for the next release (expected within a few weeks) currently stands at: - - - Add missing patch for upstream PR38579. - - - Adjust linker spec to set TSAWARE flag on executables. - - - Supply a version compiled for Cygwin-1.5. If there's anything else you think is important, please contact the Cygwin mailing list with your suggestion. ------------------------------ooOOOoo------------------------------ PLEASE SEND BUG REPORTS, PROBLEMS, ETC. TO THE CYGWIN MAILING LIST. ------------------------------ooOOOoo------------------------------ OBTAINING THE RELEASE ===================== 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.exe, fill in all of the options, and make appropriate choices on the "Select Packages" screen. Because this is a full "current" version release, any gcc packages you currently have installed will be automatically selected to update, but you'll need to select the Devel category to see gcc and friends if you don't have them already installed. NEWS ==== >> > > From the README: (with some minor tweaks added in passing). gcc4-4.3.4-1 - - ------------------------------------------ This is the first full stable production release of the GCC 4 compiler package for Cygwin. All the major runtime libraries are implemented as DLLs as well as static archives. It can fully co-exist side-by-side with the older Cygwin gcc-3.4.4 series compiler. All languages are supported, although Ada and Java remain works-in-progress. Known issues in Ada and Java. ============================= The Ada compiler is currently implemented as a Frankenstein-like hybrid of Cygwin/POSIX and MinGw/w32api code. This just barely hangs together, but does not play nicely with Cygwin's pthread library functions; the outcome is problems in the tasking implementation, including race conditions that may lead to failure in early startup or termination. There are problems with the Java compiler that are less well understood, but also manifest themselves as testsuite failures in the thread- and process-related tests. These issues will be addressed in a future release of the compiler; for now, Java and Ada cannot be considered first-class languages, but remain somewhat experimental. It is likely however that both perform better than the old 3.4 series compilers. Static and shared linking of applications. ========================================== By default, user applications will be linked against these DLLs. unless the option '-static' is supplied to GCC during the build. If linking statically against libstdc++, you should also use '-static-libgcc' to link likewise against libgcc, or you will experience segfaults on program termination. This compiler should be stable and production-ready, but as is always the case with software, there may yet be bugs. Anything abnormal should be reported, in the first instance, to the main Cygwin mailing list.
