  • (Don't) crank up the warnings to 11

    The PR in question seems to be https://github.com/RoaringBitmap/CRoaring/pull/446

    I agree that the GitHub analyses are worse than useless, but I also think it highlights the friction between intrinsics and the program in which they appear. There probably is a better model.

    Installation completed the program build successfully!! https://www.reddit.com/r/openbsd/comments/yux513/comment/iwbm72c/?context=3 I configured 2 different files in .cargo (thanx @ivan_linux for https://github.com/RoaringBitmap/CRoaring/pull/412) and .profile ( https://rust-lang.github.io/rust-bindgen/requirements.html#openbsd ) But when I try to start the program unfortunately the node not starting and I get the following errors.

  • Help with CFFI, C struct decoding, best practices / portability
    1 project | /r/Common_Lisp | 15 Jan 2022
    I've been using CFFI to access the CRoaring C API to Roaring Bitmaps. It's been pretty easy so far. However I'm not experienced in lisp FFI, and I'm unsure of the way to go about the task of decoding a C structure used for iteration in the C CPI. The structure is as follows: ``` typedef struct roaring_uint32_iterator_s { const roaring_bitmap_t *parent; // owner int32_t container_index; // point to the current container index int32_t in_container_index; // for bitset and array container, this is out // index int32_t run_index; // for run container, this points at the run

    I have a build shared library build of the C API for Roaring Bitmaps and I'm just trying to figure out the right path forward to write a lisp interface to it on sbcl.

    However, you should be able to use a different version of the library that is compatible with your system. Maybe you can install the development package for `libevent` via the system package manager? That should assure a working state. Otherwise you should be able to download a compatible version from https://libevent.org/ (either binary or source and build it yourself).

    They're different. Node uses libuv while chromium uses libevent. You're also seeing different APIs for working with the event loop like nextTick() in Node that doesn't exist in browsers.
