When I type make (after making various fixes to get make to complete) I get this far:
/usr/bin/gcjh -jni -bootclasspath ../lib: -o ../../../../../gcc-4_2-branch/libjava/classpath/include/gnu_java_util_prefs_gconf_GConfNativePeer.h gnu.java.util.prefs.gconf.GConfNativePeer /usr/bin/gcjh -jni -bootclasspath ../lib: -o ../../../../../gcc-4_2-branch/libjava/classpath/include/gnu_java_net_VMPlainDatagramSocketImpl.h gnu.java.net.VMPlainDatagramSocketImpl gcjh: gnu.java.net.VMPlainDatagramSocketImpl: no such class make[5]: *** [../../../../../gcc-4_2-branch/libjava/classpath/include/gnu_java_net_VMPlainDatagramSocketImpl.h] Error 1 make[5]: Leaving directory `/opt/gcc-4_2-build-1/i686-pc-linux-gnu/libjava/classpath/include' make[4]: *** [all] Error 2 make[4]: Leaving directory `/opt/gcc-4_2-build-1/i686-pc-linux-gnu/libjava/classpath/include' make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory `/opt/gcc-4_2-build-1/i686-pc-linux-gnu/libjava/classpath' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/opt/gcc-4_2-build-1/i686-pc-linux-gnu/libjava' make[1]: *** [all-target-libjava] Error 2 make[1]: Leaving directory `/opt/gcc-4_2-build-1' make: *** [all] Error 2 The reason that make breaks at this point is given here: http://www.gnu.org/software/classpath/announce/20061211.html Part of that page says: Runtime interface changes: * gnu.java.net.VMPlainDatagramSocketImpl removed. The gcc-4_2-branch SVN is incorrect to be out of sync with classpath and include things that are removed. This makes it unnecesarily hard to compile and leaves us to try to patch/fix/alter files to cause make to complete - for a feature that is already removed. It would be nice if the configure scripts could do a better job of scanning for what is available and at least warning (better yet fixing!) and suggesting either the means to fix it or sending us to a web page that describes what we must do.

When I run ./configure (the "root/main" configure) with the above options it completes quite quickly and uneventfully. I am running Debian gnu/Linux (stable) and have updated yesterday. I have libgcj.so.70 and "many" other newer packages that the gcc-4_2-branch requires to compile (and the "stable" version of Debian is many versions behind in it's packages). 1): ./configure does not even say what languages it is going to attempt to compile (if I alter the order of the --enable-languages=c,c++,ada,fortran,objc,obj-c++ to [for example] --enable-languages=c,c++,fortran,ada,objc,obj-c++ then it DOES mention which languages that it will be attempting to compile). Regardless of whether the order is presented exactly as the scripts would output it OR whether the order you choose your languages does not "exactly match" the order that the script would output it the script ought to say what languages it will be (attempting to) compile. 2): As mentioned in the bug#1 above, ./configure completes without much trouble or many messages (when I configure with the above options). The build works well and make runs through everything quite fast - until it gets to the libjava part of the compile (_almost_near_the_end_of_all_the_effort_!) (avoiding yelling ;) ). Then the make breaks. Simply fixing it and typing "make" again is not good enough - it won't re-start "cleanly"; you MUST delete (or can rename) "i686-pc-linux-gnu/libjava" and then type "make" so it re-builds the entire libjava directory from scratch - seldom will it re-build after fixes since it doesn't re-run the sub-configure scripts to check that things are "sane". 3): What is really a pain about the main ./configure script is that it completes and lets you type "make" with NO warnings (until the libjava directory is mostly finished) then a few of the sub-configure scripts complain that you don't have this, that or the other installed (or it is not a new enough version). OF _course_ installing the suggested package then makes new dependencies on other packages being installed with newer versions. Here is some of the files I had to get to compile with the above options fed to the main ./configure script (and it did NOT even bother to run pkg-config to check and tell me until hours into the compile when a sub-configure script tells you). -rw-r--r-- 1 root root 1321109 Feb 26 11:07 GConf-2.16.1.tar.bz2 -rw-r--r-- 1 root root 483363 Apr 20 01:13 atk-1.9.1.tar.bz2 -rw-r--r-- 1 root root 2973689 Apr 20 01:31 cairo-1.2.6.tar.gz -rw-r--r-- 1 root root 2925342 Apr 20 01:42 glib-2.12.11.tar.bz2 -rw-r--r-- 1 root root 15031543 Apr 20 00:00 gtk+-2.10.11.tar.bz2 -rw-r--r-- 1 root root 1356322 Apr 20 01:47 pango-1.16.2.tar.bz2 -rw-r--r-- 1 root root 969993 Apr 20 14:21 pkg-config-0.20.tar.gz I can't "apt-get" these (without modifying /etc/apt/sources.list) since they are not "stable") but gcc-4_2-branch requires all these bleading edge versions to compile. Don't get me wrong. I don't mind getting and installing them ! - My complaint is that the ./configure script should mention (before typing "make") that I need to spend some time upgrading and installing various new versions of packages I already have. I also need to read the docs and google the web to determine what order to install everything in so that each package can ./configure itself with all features available. I found this order worked for me: Cairo, GLib, Pango, ATK, then GTK+. I (am reasonably certain that I) can fix all this myself so please no one rush to help me. I will post the build-log shortly and put a link on this page to the output of "make -i check". Just letting the 'powers that be' know that ./configure should check dependancies better and it would be kind if configure could offer a little advice (simply "You need to install 'xyz version 123.21.2' or newer") or point us to a web page that gives detailed instructions. I am using gnu/Linux as an OS, it would be great if I could simply type "make" and then "make install" (no matter what my ./configure options are). Failing that a warning that the compile can't be completed without doing this that and the other thing would be better than the make breaking when it is nearly finished. PS: Not angry. I've compiled gcc-4_2-branch a couple of dozen times over the past few months. Just discovered this bug (by adding new ./comfigure options and trying a new OS) and am happy to report it and offer suggestions. Thanks all for the great compiler. The "C" compiler is what I used to compile my kernel - that is how much I trust gcc-4_2-branch - my system has had no trouble and all the modules work fine. -- Summary: gcc-4_2-branch uses class that has been removed - breaks make Product: gcc Version: 4.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libgcj AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: rob1weld at aol dot com GCC build triplet: i686-pc-linux-gnu GCC host triplet: i686-pc-linux-gnu GCC target triplet: i686-pc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31650
