Improvements Eclipse Installation
by sami wagiaalla 15 Feb '12

15 Feb '12

Hi, The way we currently install Eclipse plugins in Fedora is incorrect and somewhat fragile. RPM places all the plugin artifacts in the proper directories. However that does not update the eclipse metadata. This means that until the next time eclipse starts it is unaware of the newly installed plugins. Because the user would normally run Eclipse not as root Eclipse does not have permission to write to the meta data files located in the installation directory. It therefore creates a parallel version in the user's home directory ~/.eclipse. This creates a fragile installation and leads to a whole host of problems. To improve this I have written apatch which runs the Eclipse reconciler during rpm installation. The Eclipse reconciler is an Eclipse application which goes through and checks the installation directories and updates the eclipse metadata with any newly installed plugins. To add support for this in your eclipse package you have to add the following line to your rpm spec file: %_eclipse_pkg [package name] Here is an example from the eclipse-rse spec file for the eclipse-rse-sdk rpm: %package sdk [...] %_eclipse_pkg sdk The above macro expands to the following: %post sdk touch /var/run/eclipse/run-reconciler %postun sdk touch /var/run/eclipse/run-reconciler if [ $1 == 0 ]; then eclipse-reconciler.sh fi %posttrans sdk eclipse-reconciler.sh I apologize if you have experienced instability in Eclipse installations on rawhide, it is probably due to these changes. Please let me know if you have any comments questions or suggestions. I will be filing a request to update the Eclipse packaging guidelines. If you are interested in the details of the work, here is a summary in the form of a patch: http://fpaste.org/pPEC/ Cheers, Sami

Shared library paths for native linker
by Petr Pisar 23 Jan '12

23 Jan '12

Hello, I have a non-java package (pl) which links to jvm. Build scripts of pl needs to locate directories with libjava.so, libjvm.so etc. and instruct native linker (ld) where to find them (-L option). Current implementation in the pl.spec is uggly (a lot of ad-hoc hacks for each platform which requires tuning time to time <https://bugzilla.redhat.com/show_bug.cgi?id=740897>). So I decided to find ultimate way how to obtain path for linker and Java home directory. Unfortunatelly, I did not find any. So I've written one. You can find it as attachment at the afore-mentioned bug report. Usage is inspired by pkg-config: $ javac JavaConfig.java $ java JavaConfig --home /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre $ java JavaConfig --libs-only-L -L/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/lib/amd64/server -L/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/lib/amd64 -L/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/../lib/amd64 -L/usr/java/packages/lib/amd64 -L/usr/lib64 -L/lib64 -L/lib -L/usr/lib I can bundle the tool to my `pl' package, but I think it could be helpful for others too. So I'd like to ask Java SIG whether it wants to adopt it (e.g. as a part of JDK). -- Petr
