OK, here's how this is done. It's actually easy but I'll include |
| 9 |
specific details for you, just in case you're new to this: |
| 10 |
|
| 11 |
* If it doesn't already exist, create the directory "/etc/portage" |
| 12 |
|
| 13 |
* Then create the file "/etc/portage/package.unmask" if it doesn't |
| 14 |
already exist. |
| 15 |
|
| 16 |
* Add the following line(s) to that file (comments may be |
| 17 |
omitted): |
| 18 |
|
| 19 |
#---------------- |
| 20 |
dev-java/sun-jdk |
| 21 |
# (or whatever vendor package you want -- use the full name) |
| 22 |
dev-java/java-sdk-docs |
| 23 |
# (if you have your "doc" USE flag on) |
| 24 |
#---------------- |
| 25 |
|
| 26 |
* The above removes the package mask added by the Gentoo |
| 27 |
developers. However, since the sun-jdk 1.5 package is also |
| 28 |
marked unstable ("~"), you may need to enable the "testing" |
| 29 |
profile for these packages as well. Unless your system is set |
| 30 |
to ~ you will need to perform the following: |
| 31 |
|
| 32 |
* If it doesn't already exist, create the file |
| 33 |
"/etc/portage/package.keywords". |
| 34 |
|
| 35 |
* Add the following lines to that file, where "~arch" is the |
| 36 |
unstable flag for your architecture (e.g., most likely ~x86 or |
| 37 |
~amd64). Comments may be omitted, of course: |
| 38 |
|
| 39 |
#---------------- |
| 40 |
dev-java/sun-jdk ~arch |
| 41 |
dev-java/java-sdk-docs ~arch |
| 42 |
#---------------- |
| 43 |
|
| 44 |
|
| 45 |
That should do it. You can now emerge the package with a standard |
| 46 |
command: |
| 47 |
|
| 48 |
emerge -av dev-java/sun-jdk |
| 49 |
|
| 50 |
|
| 51 |
** VERY IMPORTANT ** |
| 52 |
|
| 53 |
Unless you know what you're doing, I strongly recommend that you leave |
| 54 |
your system VM set to a 1.4 JDK/runtime. Your message didn't indicate |
| 55 |
if you have one installed, so I'll assume you are using Blackdown (which |
| 56 |
is 1.4). If you aren't, you should install it now: |
| 57 |
|
| 58 |
emerge -av dev-java/blackdown-jdk |
| 59 |
|
| 60 |
(or use the JRE... I'm just giving examples at this point) |
| 61 |
|
| 62 |
** Back to the WARNING ** |
| 63 |
|
| 64 |
Installing the new sun-jdk will usually set your system VM to that one |
| 65 |
(which is 1.5). To fix this and set a 1.4 system VM, you need to |
| 66 |
perform the following steps *AFTER* the emerge: |
| 67 |
|
| 68 |
* Run the following command (as root) to set a new 1.4 system VM: |
| 69 |
|
| 70 |
java-config --set-system-vm=blackdown-jre-1.4.2.02 |
| 71 |
|
| 72 |
(assuming you have that version of the blackdown JRE installed) |
| 73 |
|
| 74 |
* Now set your user VM to the 1.5 JVM. Run the following command |
| 75 |
as you standard user account(s): |
| 76 |
|
| 77 |
java-config --set-user-vm=sun-jdk-1.5.0.05 |
| 78 |
|
| 79 |
(assuming you installed that version of the sun-jdk) |
| 80 |
|
| 81 |
|
| 82 |
That should do it. Enjoy! |

No problem at all. |
