Hi, So I think I'm nearly there (part of the scm attached).The last thing I'd like to do is run the python tests inside the cargo-build-system but couldn't find an example of it. I don't understand how to do that.
I get the following error, which is most probably me not knowing how to write scheme.
``` error: in phase 'check-python-module': uncaught exception: wrong-type-arg "apply" "Apply to non-list: ~S" (#f) (#f) phase `check-python-module' failed after 0.0 seconds Backtrace: 8 (primitive-load "/gnu/store/c2v51hzvlji63jbh0jwn5dbz10j…") In guix/build/gnu-build-system.scm: 908:2 7 (gnu-build #:source _ #:outputs _ #:inputs _ #:phases . #) In ice-9/boot-9.scm: 1752:10 6 (with-exception-handler _ _ #:unwind? _ # _) In srfi/srfi-1.scm: 634:9 5 (for-each #<procedure 7ffff5f29c20 at guix/build/gnu-b…> …) In ice-9/boot-9.scm: 1752:10 4 (with-exception-handler _ _ #:unwind? _ # _) In guix/build/gnu-build-system.scm: 929:23 3 (_) In unknown file: 2 (_ "/gnu/store/qzx9n7452cw0w11c96gvijdnmk6v82m2-python…" …) In ice-9/boot-9.scm: 1685:16 1 (raise-exception _ #:continuable? _) 1685:16 0 (raise-exception _ #:continuable? _) ice-9/boot-9.scm:1685:16: In procedure raise-exception: In procedure apply: Apply to non-list: #f ``` Thanks Alexis On 15/02/2024 22:08, Alexis Simon wrote:
Hi,So right now I'm trying to go the splitting in two packages way, similar to what is done for python-cryptography.So I managed to build the first one that produces a header file in the store /gnu/store/*/lib/header.hIn the second package, I don't get how to copy this file inside the build. I've been trying something like this:``` (native-inputs (list python-fwdpy11-rust-lib)) (arguments (list #:phases #~(modify-phases %standard-phases (add-before 'build 'copy-rust-lib (lambda* (#:key native-inputs #:allow-other-keys) (copy-file (search-input-file native-inputs "lib/fp11rust_api.h") "lib/core/internal/fp11rust_api.h")))))) ```Which complains there is no match, because it seams the package store path is not present in the native-inputs, although I specify it in the package.Thanks, Alexis On 13/02/2024 13:55, Alexis Simon wrote:Fair enough, I just meant that it's pretty hard as a newcomer to know which build system You're supposed to use to start with when encountering a project where several languages are used.Alexis On 13/02/2024 13:46, Carlo Zancanaro wrote:On Tue, Feb 13 2024, Alexis Simon wrote:Ok, this seems really counter intuitive though to go and use the cargo build system for a python package only have a tiny part in rust.I'm not sure why this is counter-intuitive. The existence of any rust at all means you need to build rust code. The normal way to do that in Guix is to use the cargo-build-system. Equally, I don't find it strange that the upstream build instructions[1] ask me to install a rust compiler and cbindgen. I need to do that if I want to build rust code. It's also worth noting that there are 22 packages in Cargo.lock[2], so building the one rust file in the repository is a bit more involved.
