Hi! |
| 2 |
|
| 3 |
This is a report about what I experienced when switching to the |
| 4 |
axxo-overlay. I used sun-jdk-1.5 as system vm before. Those were the |
| 5 |
(successful) steps that got me there: |
| 6 |
|
| 7 |
* checkout and activate overlay |
| 8 |
* remerge jdk packages |
| 9 |
* remove stale config files in /etc/env.d/java that do not have |
| 10 |
PROVIDES_TYPE and PROVIDES_VERSION set |
| 11 |
* java-config, setting 1.5 as system vm again (got changed by remerge) |
| 12 |
* env-update |
| 13 |
* start new session (su -) to get clean environment (without JAVAC set!) |
| 14 |
* emerge ant-core (will fail if JAVAC is set to 1.5 compiler) |
| 15 |
Annotation: BOOTJAVAC_OPTS should probably set to include -source and |
| 16 |
-target, and JAVAC should perhaps be set by ebuild or |
| 17 |
unset so that ${JAVA_HOME}/bin/javac is used |
| 18 |
* unmerge jsch and jdepend (which had classes in 1.5 format which caused |
| 19 |
ant to fail with an UnsupportedClassVersionError) |
| 20 |
* remerge all installed 1.5 files in correct order using |
| 21 |
class-version-verify.py from the gentoo-wiki. |
| 22 |
* emerge -uavND world |
| 23 |

There were two bugs in the second to last step. |
| 25 |
|
| 26 |
dev-java/commons-modeler-1.1 fails. It depend on a sun-jmx-1.2.1 but |
| 27 |
this version is named simply "jmx" by java-config, so I had to manually |
| 28 |
update to sun-jmx-1.2.1-r1 before updating commons-modeler-1.1. |
| 29 |
I did not yet file a bug for this as I experienced this only with |
| 30 |
axxo-overlay so far, and don't know if the main portage tree has the |
| 31 |
same problem. |
| 32 |
|
| 33 |
dev-java/gnu-jaf-1.0-r2 fails. "make: invalid option -- 1". I changed |
| 34 |
"-k1" to "-j1" in the ebuild. Looks very much like a typo. |
| 35 |
|
| 36 |
The update world is still running, but I gotta go. |
| 37 |
|
| 38 |
This is the second time I had trouble with the /usr/bin/ant script |
| 39 |
loading classes into the classpath that I did not want. The other time |
| 40 |
was when I wanted to use a development snapshot of cup from |
| 41 |
http://www2.in.tum.de/projects/cup/ but this did not work as the cup |
| 42 |
bundled with xalan. I would really want some way to set an environment |
| 43 |
variable or command line flag and thus select the list of packages |
| 44 |
loaded into the classpath for ant, overriding the list currently |
| 45 |
included. Then one would not have to unmerge jsch and jdepend but could |
| 46 |
instead set this package list to include only the list of dependencies |
| 47 |
of the package currently emerged. |
| 48 |
I filed this as http://bugs.gentoo.org/show_bug.cgi?id=111227 |
| 49 |
|
| 50 |
Another question yet is if xalan does indeed need cup itself or if the |
| 51 |
cup runtime library would be enough. If someone has time to look into |
| 52 |
this, feel free to do so, but this has low priority for me right now. |
| 53 |

I first tried to use gentoo-java-experimental and axxo-overlay together, |
| 55 |
given in this order. This failed for sys-libs/db-4.2.52_p2-r1. This is |
| 56 |
the reason why I chose to update to axxo-overlay first and try |
| 57 |
gentoo-java-experimental later this week. |
