build.log.gz
In the ebuild I don't see the \"$(java-pkg_javac-args)\" which is recommended in https://wiki.gentoo.org/wiki/Java_Developer_Guide#Using_java-pkg-opt-2.eclass if use java; then myconf="${myconf} --with-javac-args=\"$(java-pkg_javac-args)\"" fi (In reply to Khumba from comment #0) > [...] > > ~ # eselect java-vm list > > Available Java Virtual Machines: > > [1] openjdk-bin-8 > > [2] openjdk-bin-11 > > [3] openjdk-bin-17 system-vm Is the problem specific to openjdk-17 or does it also happen with -8 or -11? It happens on openjdk-bin-11 too. My program depends on Java 11+ so I didn't try with -8. Looking for references in the tree to JAVA_JVM_LIBRARY and JAVA_INCLUDE_PATH, I see only one file, portmidi-234-cmake.patch. I don't see what should be setting these variables though. If I set all three variables manually in mycmakeargs, then JNI detection is fixed, and the build completes, with proper source and javadoc JARs too which the ad hoc 3.4.2 Java install code didn't do, that's exciting: > # Bindings > -DBUILD_PYTHON_BINDINGS=$(usex python) > -DBUILD_JAVA_BINDINGS=$(usex java) > + $(usex java -DJAVA_AWT_LIBRARY=/etc/java-config-2/current-system-vm/lib '') > + $(usex java -DJAVA_JVM_LIBRARY=/etc/java-config-2/current-system-vm/lib '') > + $(usex java -DJAVA_INCLUDE_PATH=/etc/java-config-2/current-system-vm/include '') > -- Found JNI: /etc/java-config-2/current-system-vm/lib > >>> Merging sci-libs/gdal-3.5.0-r5 to / > --- /usr/ > --- /usr/share/ > >>> /usr/share/java/ > >>> /usr/share/java/libgdalalljni.so > >>> /usr/share/java/gdal-3.5.0.jar > >>> /usr/share/java/gdal-3.5.0-javadoc.jar > >>> /usr/share/java/gdal-3.5.0-sources.jar > >>> /usr/share/java/gdal-3.5.0.pom I haven't tested whether this build runs yet, I'll do that tomorrow. Also not sure if there's a better way than hard coding the current JVM path. Maybe cmake.eclass could set these variables automatically if USE=java, since FindJNI.cmake is a standard cmake module, then the gdal ebuild wouldn't need to be adjusted at all. The new build works for me, apart from libgdalalljni.so not being in java.library.path by default and needing 'java -Djava.library.path=...' at runtime, since my program isn't packaged as a Gentoo ebuild.
I thought I'd try using java-pkg_doso, and while /usr/lib64/gdal still isn't in the default library path, it seems to be following Gentoo policy more closely now.
Attaching my current working ebuild.

gdal-3.5.0-r5.ebuild

gdal-3.7.0.ebuild with JAVA_* set
Sure thing, here's a patched 3.7.0 ebuild. I've taken inspiration from the sun-jai-bin ebuild and added a postinst message about the need to invoke java with -Djava.library.path to be able to use the bindings.
This ebuild builds for me, but unfortunately on the project we were using this for, we migrated away from GDAL, so I am not able to test it at runtime. I would appreciate if someone else could do so.
Thanks!

Patch for gdal-3.7.0.ebuild with JAVA_* set
(In reply to Khumba from comment #13) > Created attachment 862622 [details, diff] [details, diff] > Patch for gdal-3.7.0.ebuild with JAVA_* set Did setting --with-javac-args and moving jdk-1.8:* to DEPEND not help? I'm going to merge this for now (thank you!) given it's currently pretty broken and I feel bad for leaving it that way.

This change passes in the system VM symlink explicitly, and also installs the JNI shared library in the proper location for Gentoo via 'java-pkg_doso', rather than in the same directory as the JAR.

I'm not sure
--with-javac-args="$(java-pkg_javac-args)"
is applicable because --with-javac-args appears to be some autoconf-style option, and GDAL uses cmake. As far as I can tell, this flag is just an example, I don't see it anywhere in the tree (or am I missing something?). Also, java-pkg_javac-args() seems to only produce "-source 1.8 -target 1.8" and I'm not sure this helps with the library run path.
At least, I think a better fix (than my patch) is to make gdal inherit from one of the java eclasses and use the logic there to retrieve the VM, so that e.g. it respects JAVA_PKG_FORCE_VM. Even better might be to make cmake.eclass detect USE=java and pass these -D... options itself, but I'm not sure what the best way is to get cmake.eclass and java-*.eclass to cooperate. Is it acceptable style for cmake.eclass to check for java-utils in INHERITED from a phase function (and then call its functions)? Making cmake.eclass unconditionally inherit a Java eclass seems wrong.
Thanks for merging, Sam!

Okay, I have to apologize, that works, I had missed a few things in seeing why. Let's apply Volkmar's patch please. (In reply to Khumba from comment #19) > Okay, I have to apologize, that works, I had missed a few things in seeing > why. Let's apply Volkmar's patch please. The reason why Volkmar is right (not his fault!) is because the Java eclasses are insane and don't follow conventions. We want to fix them soon (TM). (They do weird things like parsing *DEPEND instead of using normal options to control behaviour. They don't actually let you use the full spectrum of legal dependencies either.)
