06:24 <eldruin[m]> Hi everybody, is there a chinese-speaking person here that would be willing to review Jzow's translation?

06:24 <eldruin[m]> See: https://github.com/rust-embedded/rust-raspberrypi-OS-tutorials/pull/187

12:27 <SeanLyons[m]> I am trying to link a c static library into my rust program. Does anyone know if there is any requirements of the library for `rust-lld` to like it? I am quite sure that I have the right `-L` and `-l` options. I am calling rustc directly to strip out any potential issues with cargo or build.rs....

12:30 <SeanLyons[m]> diondokter[m]: It's not right. This is just a static library of baremetal C code. Does the linker look at this? I have linked this same library into a C program before, but I assume it doesn't check?

12:30 <SeanLyons[m]> * at this field? I

12:31 <diondokter[m]> I don't know if it matters. But it's the only thing that stood out to me

12:34 <JamesMunns[m]> I've never tried it without cargo, but with a build rs, I usually do:... (full message at <https://catircservices.org/_matrix/media/v3/download/catircservices.org/szOrCbkbVpkoNnbEsGDImoiK>)

12:38 <SeanLyons[m]> JamesMunns[m]: Yeah, I started with this in build.rs... (full message at <https://catircservices.org/_matrix/media/v3/download/catircservices.org/HuWJbmtlpWBTeJdAAHmOBKlL>)

12:40 <JamesMunns[m]> is the file called libdriverlib.a?

12:41 <JamesMunns[m]> rustc-link-lib prefixes the string you give it with lib and suffixes it with .a

12:45 <SeanLyons[m]> Ah well that was it. 🤦‍♂️ Renamed the library to libdriverlib and its happy.

12:45 <diondokter[m]> Ah! Haha yeah, that tripped me up in the past as well

12:46 <SeanLyons[m]> SeanLyons[m]: It does feel like an easy footgun though. Even the error message that it spit out said this

12:46 <SeanLyons[m]> `-l "/Users/seanlyons/dev/rust/cc13x2-cc26x2-flash/lib/driverlib.a"`

12:47 <M9names[m]> FWIW you get a more details from readelf if you use `readelf -h -A`

12:47 <M9names[m]> it's probably only going to help you if you try to use a lib that uses more instructions than your variant of the ISA but it's kinda nice

12:48 <s7rul[m]> <SeanLyons[m]> "It's not right. This is just a..." <- UNIX - System V is the OS/ABI is what cargo generates for emeded code targeting ARM so is probobly right.

12:48 <M9names[m]> yeah it's fine

12:49 <SeanLyons[m]> Huh TIL, I took a look and plenty of other C static libraries I have been using and other rust libraries had UNIX - System V is the OS/ABI as well.

12:50 <JamesMunns[m]> like, iirc ld and lld both act weird af about this in automatic prefixing and stuff

13:05 <SeanLyons[m]> <JamesMunns[m]> "> <@seanmlyons22:matrix.org..." <- You're right: https://releases.llvm.org/2.5/docs/CommandGuide/html/llvm-ld.html

13:05 <SeanLyons[m]> "If that fails, it looks for liblibrary.bc, liblibrary.a, or liblibrary.shared library extension, "

13:05 <SeanLyons[m]> Thanks for saving me some time, wouldn't have figured that one out. Now to figure out how to disable that behavior.

14:23 <dalepsmith[m]> The lib{name}.a convention goes back centuries.. Well, decades at lest.

14:24 <dalepsmith[m]> .5 centuries

15:46 <thejpster[m]> Can I get a final thumbs up on https://github.com/rust-embedded-community/embedded-sdmmc-rs/pull/95 please?

15:46 <thejpster[m]> If I get it merged I might stop fiddling with it.

15:46 <ryan-summers[m]> I'm looking over it now :)

15:50 <thejpster[m]> oh, no, I found another bug

15:50 <thejpster[m]> Let me quickly sort https://github.com/rust-embedded-community/embedded-sdmmc-rs/issues/75

15:51 <ryan-summers[m]> Honestly, PR is pretty large. I'm a fan of moving fast and breaking things. If you're not releasing it to crates.io, it's always fine for master to have defects IMO

15:51 <ryan-summers[m]> s/master/main/

15:55 <thejpster[m]> I get that, but people keep being sad at me that their SD card is corrupted

15:56 <ryan-summers[m]> If they're using main, that's their own fault

15:56 <thejpster[m]> 75 is fixed

15:57 <thejpster[m]> fair. I'll push for reviews before I get quite so far next time.

15:57 <ryan-summers[m]> And honestly one of the reasons I've been slow to review is because the PR is huge

15:58 <ryan-summers[m]> Kept looking and dreading :) \but now it's friday

15:58 <thejpster[m]> it's not so bad commit by commit

15:58 <thejpster[m]> ryan-summers[m]: which meant I kept making it bigger :rofl:

15:58 <thejpster[m]> sorry about that

15:58 <ryan-summers[m]> It's no biggie tbh, just gotta find the bock
