Perhaps it should. On the other hand you don't have to, it will be set automatically during the vm update process (which is described). java-config-2 -s is only mentioned because it differers from the plain portage case.
>> Anyway I have two problems right now: >> 1. If I do java-config-2 -S sun-jdk-1.4, ant-core continues to build >> with sun-java-1.5
Because system vm has nothing to do with emerge. For that you set the build jdk. Note that system vm can be a jre or a jdk, while compilation jdk has to be a jdk. This procedure differs from a plain portage installation, and should perhaps be mentioned somewhere.
>> 2. Junit does not compile even having compiled ant-core with 1.4 vm >> (I had to modify jdk.conf)
The the default jdk.conf will not make 1.4 sources build with a 1.5 jdk, so you do not *have* to modify jdk.conf. However, you *must not* changee jdk.conf to an invalid state, which is currently possible (and you must have done). Perhaps there should be a warning in the sample file? (something like "# Warning: Do NOT set a 1.5 jdk for use with anything but 1.5 sources!") If Junit doesn't compile after having (re-)emerged all java-packages with a corrected jdk.conf, file a bugreport. To find all packages you have to re-emerge use java-1.5-fixer from the list. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (GNU/Linux) Comment: Using GnuPG with Mozilla - iD8DBQFEPjdQOOpxqcksWu4RAjjqAJ42uRyFXdqavyXNszJvqHOGiB8wTgCgnHsu wqQylcrz1/tz8ArfaK9ovoM= =bc0Z -----END PGP SIGNATURE----- -- gentoo-java@g.o mailing list
