Installation issue on Intel MacOS Sequlia 15.0.1

[Niu-Liu]

Hi Akiyama san,

Thank you for providing a very convenient way for installing difmap, which makes many Difmap users' life easier.

I encountered an issue while trying to install difmap. The error messages are shown below while the log files are attached. I also downloaded the source pacakge and compiled it, which did not return this error message. It succeeded in compiling libpager.a. Instead, it returned an error message similar to issue#3. Passing an argument "-Wno-error=incompatible-pointer-types" to CFLAGS would not help for my case.

Do you have anysuggestions?

Best regards, Niu

Thanks for the issue. I don't have Sequoia in local environments as our institute recommends against installing it for now because it provides many breaking changes in our software ecosystem. So in the mean time I can't reproduce the results.

Anyway, this seems to be a similar issue with the previous one. I think probably an origin is that some issues ignored or handled ok implicitly in previous compilers are flagged as errors in the latest Xcode environment after macOS 15. I will explore issue but it would take a time as I'm busy next few weeks for other commitments.

In the mean time, I have a separate question. You are apparently using intel machine for your macOS 15. Did you encounter this issue in PGPLOT, when you installed PGPLOT? https://github.com/kazuakiyama/homebrew-pgplot/issues/6

Ok, I confirmed that the formula still works for macOS 14 in both intel and Apple Silicon architecture. I will explore any way to test it in a newer macOS. Sorry that I can't offer immediate help. Keep you posted about the issue.

Thank you for the reply. I successfully installed PGPLOT and SCHED via your repository. It was really a bad idea to upgrade to a new OS :-(

Thank you for the help. I can use my server (Ubuntu) instead.

Hi Akiyama-san,

Just wanted to share some good news: today I patched the diff file in your repository and manually compiled the code—it worked! After upgrading macOS to Sequoia 15.1, I retried installing Difmap via brew install difmap and that also succeeded.

Thanks again for your support.

@Niu-Liu Thanks for the heads up! Glad to hear that the issue has spontaneously resolved. Yes, sometimes waiting for the first few minor revisions often helps with issues with a newly released macOS. I think this was due to an aggressive change in some specs of the native C compiler, which might be fixed with 15.1.

I will close the issue for now. Please feel free to open when you find a similar issue.
