I’ve had this experience many times but now just installed a package from scratch. All worked as expected (maybe except the very long time), packaged installed and and compiled. Next I run the tests and … recompiled the package again. Why is that? And I further noticed that there are now two sets of…

Are you using additional test dependencies? This might introduce recompilation of the package

Pkg.test uses --check-bounds=yes, which is incompatible with the precompilation image that was generated during package installation.

Thanks, but would you mind elaborating a bit more? When developing the package I often restart Julia to force recompilation. If I run the tests immediately after using GMT (where a recompilation takes place), it always recompiles GMT again. This is no package installation. Sorry, but I don’t find t…

For me it worked fine, but maybe I did not follow the same workflow you have? Installing, then precompiling, then precompiling test environment, then testing stefan@cube ~> julia --project=(mktemp -d) -tauto (tmp.byjxPCUpkb) pkg> dev --local GMT Cloning git-repo `https://github.com/GenericMap…

I think the difference is that your attempt didn’t really installed the GMT binaries, that’s why you got the (nothing actually tested) Test Summary: | Pass Total Time GMT | 1 1 0.1s I am testing a new JLL solution but there are mysterious errors between OSs For example this …

[image] Elrod: Precompilation images in Julia 1.9 with --check-bounds=yes and --check-bounds=no are incompatible,so you need separate precompilations for both. Does not sound good to me. We’ll all end up with dozens of repeated precompiled files … and for some packages they are not exactly sm…

There’s no good way around it. Bounds-checking is implemented in the compiler: when it’s on, it generates different code than when it’s off. Since Julia 1.9 saves the compiled code, the mode you compile in matters: you can’t just change the mode after compilation is complete. But that means you nee…

[image] tim.holy: Compiling C is little different: want both -O0 and -O3? You have to compile twice. Perhaps a difference is that when developing C++, I’m basically only compiling with -O0, sanitizers, debug information, and assertions. Perhaps we should also have the habit of generally deve…
