Bug 177429 – [TRACKER] java virtuals support and migration

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description Vlastimil Babka (Caster) (RETIRED) 2007-05-07 09:59:02 UTC]

I did this in xmlgraphics-commons:
DEPEND=
                jpeg? (
                        || (
                                >=dev-java/sun-jdk-1.4
                                >=dev-java/blackdown-jdk-1.4
                                >=dev-java/ibm-jdk-bin-1.4
                                >=dev-java/jrockit-jdk-bin-1.4
                        )
                )

But that doesn't help in forcing one of these VM's to be used. So had to do this workaround:
pkg_setup() {
        java-pkg-2_pkg_setup

        if use jpeg && java-pkg_current-vm-matches kaffe; then
                eerror "Sun-private JPEG support cannot be built with kaffe."
                eerror "Please set your build VM to Sun, Blackdown, IBM or JRockit JDK."
                eerror "See http://www.gentoo.org/doc/en/java.xml for details."
                eerror "Alternatively, install this package with USE=-jpeg"
                die "Cannot build with USE=jpeg and kaffe."
        fi
}

This is called virtuals support.

Basically in this case we would have virtual-sun-jpeg or something and then have the tools look at if we need to switch vm.

xmlgraphics-commons is presently version 2.8 without such problems.
Also, java-virtuals is going away. Closing.
