db merging script
by Andrew Overholt 05 Apr '05

05 Apr '05

This is a crude example of what we could have, but it's what I've got so far: %post -n %{libname}-gtk2 if ![ -e `gcj-dbtool -p` ]; then dirname `gcj-dbtool -p` | xargs mkdir -p; gcj-dbtool -n `gcj-dbtool -p`; fi if [ -n "`find %{_libdir}/%{name}/mappings -name \*.db`" ]; then gcj-dbtool -m `gcj-dbtool -p` `find %{_libdir}/%{name}/mappings -name \*.db` `gcj-dbtool -p` fi %postun %{libname}-gtk2 if [ -n "`find %{_libdir}/%{name}/mappings -name \*.db`" ]; then gcj-dbtool -m `gcj-dbtool -p` `find %{_libdir}/%{name}/mappings -name \*.db` `gcj-dbtool -p` fi I'm not even sure if what I have will work. I'd just like to start the discussion about how best to do it. Anthony Green has raised valid concerns about multilib systems. Andrew

native and regular eclipse freezing in fc4t1
by Zlatin Balevsky 29 Mar '05

29 Mar '05

Greetings, I looked around bugzilla but there wasn't anything similar to this bug. Every time I start the native eclipse, the entire computer freezes as soon as it passes the splash screen. Hard reset is the only thing that works from that point on. I tried starting the regular eclipse 3.1M5 with gij and the result was the same; regular eclipse runs fine on the Sun jvm. This is an i386 fc4t1 system updated to the latest rawhide (from last night). Are there any options I can pass to either gij or the eclipse binary that will make it print some debugging info?

Hi, I'm having some platform and other issues building these in the build system, so in the meantime if anyone wants to try what will become the new 3.1-series RPMs: http://people.redhat.com/overholt/eclipse/rpms/ The debuginfo package is here: http://overholt.ca/rpms/eclipse-debuginfo-3.1.0_fc-0.M5.6.i386.rpm Andrew

DBus and Java
by Joe Desbonnet 27 Mar '05

27 Mar '05

I understand that the long term plan with Fedora is to expose all system configuration information via DBus. Are there any Java bindings for this yet? Part of the reason I ask is I'm wondering what is (or will be) the correct way to query locally installed RPMs. Thanks, Joe.

Eclipse Problems - Create a "Standard Make C Project"
by Keith Sharp 26 Mar '05

26 Mar '05

Hello, When I try to create a new "Standard Make C Project" it fails at the last stage of the wizard, when I click finish, by displaying a dialog box that says "Project cannot be created Reason: Internal Error:". All the dialog has is an ok button! I can create a "Managed Make C Project" with no problems. Any thoughts on how to debug this further? I am running FC4T1 with Eclipse updated to latest Rawhide: $ rpm -qa eclipse\* eclipse-cdt-3.0.0_fc-0.M5.1 eclipse-changelog-2.0.1_fc-18 eclipse-ecj-3.1.0_fc-0.M5.13 eclipse-pde-devel-3.1.0_fc-0.M5.13 eclipse-pde-3.1.0_fc-0.M5.13 eclipse-platform-3.1.0_fc-0.M5.13 eclipse-jdt-3.1.0_fc-0.M5.13 eclipse-platform-devel-3.1.0_fc-0.M5.13 eclipse-pydev-0.9.0_fc-4 eclipse-jdt-devel-3.1.0_fc-0.M5.13 eclipse-bugzilla-0.1.0_fc-8 Thanks, keith.

Profiling ecj (was: Using the natively-built Eclipse compiler)
by Ziga Mahkovec 25 Mar '05

25 Mar '05

I upgraded to libgcj-4.0.0-0.32 and eclipse-ecj-3.1.0_fc-0.M5.12. The results for compiling classpath: ecj | ecj-native | jikes ------------------------------------------------------------- real 1m31.786s | real 0m16.207s | real 0m8.423s user 1m22.796s | user 0m14.925s | user 0m7.052s sys 0m1.369s | sys 0m1.020s | sys 0m0.755s (ecj-native went from 24.5s to 16.2s as a result of -O2) I also uploaded oprofiles for ecj[1], ecj-native[2] and ecj-native-with- the-old-gcjlib-tools-jar[3]. Note that I'm running a Centrino so the oprofile driver falls back to timer interrupt mode.

I've attached a patch for the changelog plugin. This will fix up the native-compilation situation until everything's sorted out. Andrew

gcj-db directory and merge/update scripts
by Phil Muldoon 22 Mar '05

22 Mar '05

Lets pin down where we want to put the application .db's that will be merged into the main gcj db. We are about the make changes to the Eclipse spec files to take advantage of the new central .db idea. How about something like: /var/cache/gcj-db-{gcj-version-no} or something to that effect? Will them main db go in there, and how should we structure the directory structure in here to avoid name collisions? I'm presuming we would want all application db's in there too. Also we need a script that does the merge in a generic way, that all spec files can call in %post (to merge their db in with the main db). How should we write this, and also, where should it be put. Should GCC own this too? Just a few things to get the discussion moving, and make some decisions on these few things. Regards Phil
