 Alyssa Ross | Imagine cross compiling from glibc to musl, or x86_64 to i686 | 18:05:38 |
 maralorn | I mean I also find the code around that very confusing because it has "otherBuildInputsSystem" and "otherBuildInputs" which are both used and there is a TODO there. | 18:05:48 |
| Alyssa Ross | Cross compiling doesn't necessarily mean you can't execute | 18:05:50 |
| maralorn | I see. Fair. | 18:06:10 |
| Alyssa Ross | Which is why we have a predicate in Nixpkgs called canExecute, which stdenv uses to decide whether to have checkPhase and reference checkInputs and nativeBuildInputs | 18:06:14 |
 emily | (btw I have solved the LLVM 12 problem. still a WIP draft locally. but my experiment was a success) | 18:06:49 |
| emily | (it is a joyous occasion) | 18:07:05 |
| Alyssa Ross | * Which is why we have a predicate in Nixpkgs called canExecute, which stdenv uses to decide whether to have checkPhase and reference checkInputs and nativeCheckInputs | 18:07:40 |
| maralorn | So in this case we would want Z3 to be compiled for the target plattform, right? And for that it should be nativeCheckInputs and not checkInputs? | 18:07:40 |
| Alyssa Ross | We would want it to be for the build platform, I thought | 18:07:54 |
| emily | I assume the library invokes Z3 at runtime | 18:08:05 |
| Alyssa Ross | Since PATH was mentioned. | 18:08:06 |
| emily | so you want it for the host platform | 18:08:08 |
| emily | (you almost never want to say "target platform") | 18:08:15 |
| maralorn | Aaah, yeah. | 18:08:15 |
| emily | (unless what you are building is a single-target compiler) | 18:08:23 |
| Alyssa Ross | With strictDeps I believe checkInputs don't end up in PATH, only nativeCheckInputs | 18:08:34 |
