RFR: 7903239: ofAddress factory of function pointer type is wrong for struct returns
by Marko 02 Jan '24

02 Jan '24

When generating the lambda inside the `ofAddress` factory, it is missing the `SegmentAllocator` needed when the function returns a struct. This is [implemented for regular functions](https://github.com/openjdk/jextract/blob/0582eaf1b4cdba95f0ee8c2…, but not for function pointers. ------------- Commit messages: - 7903239: ofAddress factory of function pointer type is wrong for struct returns Changes: https://git.openjdk.org/jextract/pull/58/files Webrev: https://webrevs.openjdk.org/?repo=jextract&pr=58&range=00 Issue: https://bugs.openjdk.org/browse/CODETOOLS-7903239 Stats: 47 lines in 3 files changed: 44 ins; 2 del; 1 mod Patch: https://git.openjdk.org/jextract/pull/58.diff Fetch: git fetch https://git.openjdk.org/jextract pull/58/head:pull/58 PR: https://git.openjdk.org/jextract/pull/58

RFR: Add Dockerfile, zero-dep reproducible builds
by Gavin Ray 02 Jan '24

02 Jan '24

As title says, adds a Dockerfile that will fetch all necessary deps and build `jextract` for you on Ubuntu 22.10 It would be nice if some official JDK organization could put this on their Dockerhub, so that users could just do: $ docker run --rm -it openjdk/jextract:latest I've pushed it to my personal Dockerhub, so if anyone would like to test it out, you can use the README directions but prepend `gavinray/` before the image name: $ echo "struct Foo { int a; long b; }; int use_foo(struct Foo foo);" >> sample.h $ docker run --rm -it -v ${PWD}:/tmp/jextract \ gavinray/jextract:latest \ -I /tmp/jextract \ --source \ -l libfoo \ --output /tmp/jextract/generated \ --target-package com.example \ ------------- Commit messages: - Add Dockerfile, zero-dep reproducible builds Changes: https://git.openjdk.org/jextract/pull/74/files Webrev: https://webrevs.openjdk.org/?repo=jextract&pr=74&range=00 Stats: 75 lines in 2 files changed: 75 ins; 0 del; 0 mod Patch: https://git.openjdk.org/jextract/pull/74.diff Fetch: git fetch https://git.openjdk.org/jextract pull/74/head:pull/74 PR: https://git.openjdk.org/jextract/pull/74

RFR: Add third-party sample list to README, populate with java-vulkan.
by Michael Ennen 02 Jan '24

02 Jan '24

I made a more complex example (1000 lines, mostly because setting up a boilerplate Vulkan program is super lengthy) of using jextract on Vulkan and Win32 APIs. I think it may be too lengthy and too much of a maintenance burden to commit to the `/samples` directory, so I thought maybe including a section on third-party samples would be better. If this is not something you want to entertain that's totally understandable, but thought I would put it out there a bigger sample that interfaces with a pretty complex API may be helpful to others. ------------- Commit messages: - Add third-party sample list to README, populate with java-vulkan.

JExtract unknown type name 'intmax_t' for /usr/include/yara.h
by Maurizio Casciano 03 Jan '23

03 Jan '23

Dear All, I'm trying to generate Java bindings for the yara library but I'm getting error: unknown type name 'intmax_t' when running the jextract command: build/jextract/bin/jextract --source --output java-yara --target-package com.virustotal.yara /usr/include/yara.h even if I include the relevant additional paths: -I /usr/include -I /usr/include/yara -I /usr/lib/llvm-15/lib/clang/15.0.6/include Here is my question on Stack-Overflow https://stackoverflow.com/questions/74931278/jextract-usr-include-yara-h-th… and my GitHub repository https://github.com/MaurizioCasciano/jextract/tree/unknown_type_name_intmax_t What may be missing in the command? Best, Maurizio
