If the mtimes are equal, wouldn't that be good enough? Because that's the situation in Guix, and it seems to work fine (the source are not recompiled upon execution): --8<---------------cut here---------------start------------->8--- $ stat /gnu/store/wjpxvb4f2qakki153pd9v1i3ja3xjadw-guile-lib-0.2.8.1/share/guile/site/3.0/htmlprag.scm File: /gnu/store/wjpxvb4f2qakki153pd9v1i3ja3xjadw-guile-lib-0.2.8.1/share/guile/site/3.0/htmlprag.scm Size: 103798 Blocks: 208 IO Block: 4096 regular file Device: 0,26 Inode: 649006 Links: 10 Access: (0444/-r--r--r--) Uid: ( 0/ root) Gid: ( 0/ root) Access: 1970-01-01 09:00:01.000000000 +0900 Modify: 1970-01-01 09:00:01.000000000 +0900 Change: 2025-09-07 17:40:19.397522007 +0900 Birth: 2024-09-06 05:27:02.015439303 +0900 $ stat /gnu/store/wjpxvb4f2qakki153pd9v1i3ja3xjadw-guile-lib-0.2.8.1/lib/guile/3.0/site-ccache/htmlprag.go File: /gnu/store/wjpxvb4f2qakki153pd9v1i3ja3xjadw-guile-lib-0.2.8.1/lib/guile/3.0/site-ccache/htmlprag.go Size: 193533 Blocks: 312 IO Block: 4096 regular file Device: 0,26 Inode: 649062 Links: 6 Access: (0444/-r--r--r--) Uid: ( 0/ root) Gid: ( 0/ root) Access: 1970-01-01 09:00:01.000000000 +0900 Modify: 1970-01-01 09:00:01.000000000 +0900 Change: 2025-09-07 17:40:19.124662154 +0900 Birth: 2024-09-06 05:27:02.019439303 +0900 --8<---------------cut here---------------end--------------->8--- Guix sets both GUILE_LOAD_PATH and GUILE_LOAD_COMPILED_PATH to locate the source and byte-compiled .go files, but this should be equivalent to using a fixed location in your file system hierarchy, I'd assume. -- Thanks, Maxim
