digitalmars.D.learn - Mir blas keeps giving an error

reply Marc <mailnawman gmail.com> writes:
Using mir-blas is fundamental for implementing linear models in 
D. However it keeps giving an error, other mir libraries work 
fine.

I get the following error

```shell
/usr/bin/ld: -f may not be used without -shared
clang: error: linker command failed with exit code 1 (use -v to 
see invocation)
Error: linker exited with status 1
```

I would appreciate if anyone can help me setting it up.

BLAS can be a tricky-to-install library.
Please provide your OS, dub.json/sdl and check that BLAS is 
installed.

The examples dub.sdl is available here: 
https://github.com/istmarc/mir-examples/blob/main/dub.sdl . I've 
Archlinux installed with openblas (`/usr/lib/libopenblas.so`) and 
lapack (`/usr/lib/liblapack.so`). I can use them from c++ simply 
by linking `clang++ -lbopenblas main.cxx` and both work fine.

I have updated the examples by adding a subconfiguration of 
mi-blas. Now it works.

Nice.
I've checked your repos - you probably also could be interested 
in projects:
- Mojo lang, where tensors are integrated into the language 
https://docs.modular.com/max/api/c/tensor/
- GGML C++ library for tensors, used in llama.cpp
https://github.com/ggml-org/ggml

Those are great resources. Thanks a lot for your reply. I started 
writting a tensor library mainly to extend Eigen c++ library that 
has an unsupported tensor module. It’s great for numerical stuffs 
but doesn’t support for example slicing like numpy and Mir except 
for rows and columns of a matrix. Im not sure about how they 
approached this so that might be very interesting thing I could 
check.
