can't be build with msvc #17

Open bitbegin opened 7 years ago

bitbegin commented 7 years ago

rust msvc environment can't use pkg-config-sys crate. Is there any solutions?

Boscop commented 7 years ago

I got it working on windows with a .cargo/config build script override and the dll from here: https://sourceforge.net/projects/libusb/files/

[target.x86_64-pc-windows-msvc.'usb-1.0']
rustc-link-search = ['D:\libs\64bit']
rustc-link-lib = ['libusb-1.0']

dcuddeback commented 7 years ago

@bitbegin I only have experience building with MinGW on Windows. I don't recall whether MSVC was even an option for Rust at the time (that was nearly 3 years ago). Earlier this year, someone opened a PR for libusb-sys with a build strategy that he claims supports MSVC: https://github.com/dcuddeback/libusb-sys/pull/5. I haven't had time to test it myself, and since I'm not as familiar with Windows as I am with Unix, I could use help testing it. If you get a chance to test https://github.com/dcuddeback/libusb-sys/pull/5, I'd appreciate some feedback on whether or not it solves your issue.

@Boscop Thanks for the work-around.

Geobert commented 6 years ago

I managed to test the PR and it works after doing:

Get libusb from http://libusb.info/
create a libusb folder somewhere
inside, create a lib and an include folder
put a static version libusb-1.0.lib inside lib (I put MS64 version)
put libusb.h inside include
set up an environment var LIBUSB_DIR that point to your libusb folder

To merge the PR I just edited build.rs from .cargo\registry\src\github.com-1ecc6299db9ec823\libusb-sys-0.2.3\ and removed the target dir from my project, then build again.

I talk too fast, cargo check passes, but not cargo build after putting the example code. Linking is failing with:

error: linking with `link.exe` failed: exit code: 1120

From what I can gather, we may need legacy_stdio_definitions.lib How de we pass this kind of information in Rust?

Geobert commented 6 years ago

As a test, I've put legacy_stdio_definitions.lib in the libusb/lib folder and added println!("cargo:rustc-link-lib=static=legacy_stdio_definitions"); to the build.rs and I got rid of some unresolved symbols and have only one left:

Geobert commented 6 years ago

Ok, I've done more tries and here are my results. Using the binary provided by libusb.info, I got the link errors above. These errors seems to happen because of different CRT use during compilation. So I've taken the source of libusb and compile it using VS2015 (my toolchain is using 2015). I put this freshly compile static libusb-1.0.lib into the $LIBUSB_DIR/lib and build again my Rust example. With this lib, I got different link errors:

I'm not a linker specialist and I am quite lost now :-/

Geobert commented 6 years ago

I'm dumb: while rebuilding libusb, I forgot to set it to x64… So we have to rebuild libusb ourself in order to use it with VS2015 toolchain

In conclusion, the PR works if we have the correct libusb binary :)

theronic commented 5 years ago

@Geobert what arguments did you pass to cargo to get it use your libusb libraries?

Geobert commented 5 years ago

If I recall properly, I hacked into the .cargo folder to see if something can come out and I don't use libusb anymore so I didn't reach the phase to do a clean build with passing params to cargo.

Sorry :(

theronic commented 5 years ago

@Geobert did you switch to something else instead? I'm having a hell of a time getting it to compile for MIPS architecture.

Geobert commented 5 years ago

I'm using hidapi

AJAnderson commented 5 years ago

@Geobert sorry to necro you again. I've tried to rebuild libusb using my current build tools (2019) set to x64 but I still end up with the link errors in your earlier post (https://github.com/dcuddeback/libusb-rs/issues/17#issuecomment-384555591)

Did you do anything else after rebuilding for x64?

Geobert commented 5 years ago

As I said, I've done an ugly hack by tampering the files in .cargo but I can't remember what as I didn't use libusb in the end. Sorry :-/

seanybaggins commented 1 year ago

I'm not building for mvc but I managed to get my build for android using the following.

.cargo/config

[target.aarch64-linux-android]
linker = "aarch64-linux-android21-clang++"
rustflags = ["-C", "link-arg=-v"]

[target.aarch64-linux-android.'usb-1.0']
rustc-link-search = ['libs/arm64-v8a']
rustc-link-lib = ['usb-1.0']

Directory structure

.
├── .cargo
│   └── config
├── Cargo.lock
├── Cargo.toml
├── libs
│   └── arm64-v8a
│       └── libusb-1.0.so
└── src
    ├── bin
    │   ├── android.rs
    │   └── linux.rs
    └── lib.rs

Note: rustc-link-lib = ['libusb-1.0'] was changed to rustc-link-lib = ['usb-1.0']

Hopefully that helps someone.
