I have this dependency:

blas = "0.18.1"

During building this simple program (no types used de facto in the program):

extern crate blas;
use blas::c::*;

I get these errors:

error: linking with `gcc` failed: exit code: 1

My active toolchain is stable-x86_64-pc-windows-gnu. I want to keep it because this is the only approach I've found for debugging; The MSVC toolchain doesn't allow to run dgb and thus debug in CLion.

What can I do? Are there any other connectors between Rust and BLAS? More specifically, I need to call dsyev_. Are there any other known stable methods of calculating real eigenvalues in Rust?

  • Maybe off topic, but each time that I had to provide a soft running under windows I have cross-compiled it from Linux to Windows using http://mxe.cc/ . It has always worked like a charm even for Qt apps. There you have blas, cblas and lapack for windows without pain. – Picaud Vincent Sep 01 '17 at 16:15
  • @kennytm, no, it doesn't help. as far as i understand rust has its own gcc compiler with all dependencies in ~/.cargo/.... folder – Stepan Yakovenko Sep 01 '17 at 16:40
  • @StepanYakovenko No, `rustc` uses LLVM, but doesn't ship its own GCC compiler. – kennytm Sep 01 '17 at 18:26
  • I mean this: .rustup\toolchains\stable-x86_64-pc-windows-gnu\lib\rustlib\x86_64-pc-windows-gnu\bin\gcc.exe – Stepan Yakovenko Sep 01 '17 at 20:07
