open_index: Unable to open

[Qin1523]

Hello, my mac version is macOS Sonoma M1, gcc14. I have a problem when trying to use the difmap. When I try to use HELP command, it comes that "open_index: Unable to open /private/tmp/difmap-20240516-20455-p3h75u/uvf_difmap_2.5q/help/maths.idx."

This seems to be an easy fix as this is simply an issue of the path to help files. The current specified location in your error log seems a temporary directory only used in brew install difmap. Let me take a look at tomorrow. I will keep you posted.

It turns out that this issue has been there since from the beginning of this repository because I erroneously didn't set up the installation in a way to install all entire help files to the brew's prefix directory for difmap. Also the recent fix for issue #3 further corrupted this issue from another point (which I mentioned in my previous response).

Both of them are now fixed. Please try out Rev 5 formula (2.5p_5). You can simply do by brew update; brew upgrade difmap.

Thanks for pointing this out. I would never have found this issue by myself.

I will close this issue as I confirmed the fix in both apple silicon and intel mac. Please feel free to reopen if the issue still persists on your end.
