Re: [sage-devel] Re: Question: why does /usr/bin/gcc get called during Sage startup?

This looks pretty complicated. I used XCode 15.0.1 to build the macOS SageMath-10-3 app for Arm and XCode 13.4 for Intel. I got "duplicate rpaths" and "duplicate libraries" warnings with 15.0.1 but not with 13.4. I pasted typical gcc commands (from cvxopt) below. You can see that: (1) Both co

Thanks. The xcode-select command always exists. What works is to run the command with stderr redirected to /dev/null and then check $?. I will open a PR. - Marc On Thursday, April 25, 2024 at 4:05:34 PM UTC-5 John H Palmieri wrote: > I also don't know when the linker was fixed and whether we ne

Re: [sage-devel] Re: Question: why does /usr/bin/gcc get called during Sage startup?

I also don't know when the linker was fixed and whether we need to support systems on which it is still broken. Anyway, if you want to open up a PR to avoid the call to xcode-select, I'd be happy to take a look. We could also revive some version of the branch at #36337 to filter out the warnings

Re: [sage-devel] Re: Question: why does /usr/bin/gcc get called during Sage startup?

Take a look at the discussion at https://github.com/sagemath/sage/pull/36337, in particular https://github.com/sagemath/sage/pull/36337#issuecomment-1741293729. I saw both "duplicate rpath" warnings and "duplicate library" warnings. Some (maybe all, at least at that point) of the duplicate rpat

Re: [sage-devel] Re: Question: why does /usr/bin/gcc get called during Sage startup?

Hi John, I have noticed that .dylib files generated by Sage often have as many as 3 identical rpaths. (When building the macOS app I remove all rpaths and replace them with a single rpath which is relative, meaning it starts with @loader_path. Apple will not notarize app bundles with absolute rp

[sage-devel] Re: Question: why does /usr/bin/gcc get called during Sage startup?

Hi Marc, I just tried building Sage without `-ld-classic`. It builds, but I get warnings about "ignoring duplicate libraries", and those cause doctest failures. The lines could be modified to test whether xcode-select is present and executable first, or since Sage now does indeed build without

Another example is large-scale pure math computation on clusters. Because of Sage's size and the nature of distributive file systems, the time to startup Sage can be 30 seconds or more, which complicates things if you want to do 100,000 calculations that are only 10 seconds each. I agree th
