calling C from Clojure in Graal native: https://github.com/retrogradeorbit/graal-native-image-jni

@lee might be a nice link to add to the resources

tree sitter anyone?

fwiw, javah is apparently obsolete: https://stackoverflow.com/questions/50352098/javah-missing-after-jdk-install

^ @retrogradeorbit (nice work, btw 🙂 )

I think he used JDK8. I also still keep using JDK8 since JDK11 seems a bit experimental still in GraalVM?

fwiw, according to the SO link, one can use javac with -h in jdk8 as well

ya, coolio! will add.

fwiw, w/ slight editing it worked with graal 19.3.0 java8 + openjdk 8

nice!

to use javac instead of javah, the following seems sufficient:

cd src && javac -h . HelloWorld.java

cd src && javah -jni HellowWorld

nice, so you don't even have to compile it first?

i don't know about that -- when i remove the part of the Makefile for creating the class file, it doesn't work

javac -help has this to say about -h:

-h <directory>             Specify where to place generated native header files

ok

fwiw this is a diff for what i have now: https://pastebin.com/WDH8zv0E

it seems to work with graal 19.3.0 java11 + adoptopenjdk 11 too

nice!
