[gdal-dev] GDAL bindings support for Java 17

[adamgutonski]

Hello,

My question is, is it possible to build the GDAL bindings for Java 17? I am trying to build GDAL with Java bindings for Java temurin-17.jdk when prior I have been able to build and use the bindings successfully for Java adoptopenjdk-8.jdk, using the exact same build process. However when I run the equivalent build steps with Java 17 I continue to receive this link error when implementing the bindings:

Native library load failed.
java.lang.UnsatisfiedLinkError: no gdalalljni in java.library.path: ...
Exception in thread "main" java.lang.UnsatisfiedLinkError: 'void org.gdal.gdal.gdalJNI.AllRegister()'
at org.gdal.gdal.gdalJNI.AllRegister(Native Method)
at org.gdal.gdal.gdal.AllRegister(gdal.java:664) at Main.main(Main.java:14)

My system specs:

System Version: macOS 12.6.1 (21G217)

Kernel Version: Darwin 21.6.0

Boot Volume: Macintosh HD

Boot Mode: Normal

Secure Virtual Memory: Enabled

System Integrity Protection: Enabled

Time since boot: 15 days 20:17

Model Name: MacBook Pro

Model Identifier: MacBookPro18,3

Chip: Apple M1 Pro

When I run the build I see that the Java bindings are generated, the .jar and libgdalalljni.dylib are created in /build/swig/java. Here are the build commands used:

sudo arch -x86_64 /usr/local/homebrew/bin/cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local/bin -DBUILD_JAVA_BINDINGS=ON -DBUILD_PYTHON_BINDINGS=OFF -DCMAKE_OSX_ARCHITECTURES=x86_64 -DGDAL_USE_ZSTD=OFF

sudo arch -x86_64 /usr/local/homebrew/bin/cmake --build .

sudo arch -x86_64 /usr/local/homebrew/bin/cmake --build . --target install

Again, all of the above steps work when I am using JDK 8. So does GDAL support Java bindings for JDK 17? Is there a way to resolve the error no gdalalljni in java.library.path? Here are the path settings in IntelliJ IDE:

VM options: -Djava.library.path=/Users/<username>/code/gdal-<version>/build/swig/java:$PATH$ Environment Vars: PATH=/Users/<username>/code/gdal-<version>:/Users/<username>/code/gdal-<version>/build/swig/java:$PATH$
