Hi Martin,

The library can be accessed with the DYLD_LBRARY_PATH environment variable. I think that should work. It is also possible to access the library using accessed using @rpath

The documentation says LD_LIBRARY_PATH, for this system I have set it e.g. echo $LD_LIBRARY_PATH shows /usr/local/lib and ls -al $LD_LIBRARY_PATH/libsaxon-hec-12.4.2.dylib shows e.g. -rwxr-xr-x@ 1 root wheel 50873896 27 Jan 16:10 /usr/local/lib/libsaxon-hec-12.4.2.dylib.

But the error message points to /Users/martin/libsaxon-HEC-mac-aarch64-v12.4.2/libs/darwin/libsaxon-hec-12.4.2.dylib, not sure how to get the system to use the LD_LIBRARY_PATH lib.

As for your comment, I assume DYLD_LBRARY_PATH is supposed to say LD_LBRARY_PATH, or do we need DYLD_LIBRARY_PATH on the Mac?

It should be DYLD_LIBRARY_PATH on the Mac

Ok, changed the shell profile to set DYLD_LIBRARY_PATH , output confirms it is set e.g. echo $DYLD_LIBRARY_PATH gives /usr/local/lib.

Error message now mentions the /usr/local/lib dylib i.e.

./query

but continues to say "not valid for use in process: library load disallowed by system policy)".

Not sure what to make of it, does that library need to be signed and isn't?

Sorry, DYLD_LIBRARY_PATH is a red herring, unless you have System Integrity Protection turned off (it's on by default). This is almost certainly a Safari-setting-the-quarantine-xattr issue, which means it's a documentation issue.

On macOS 14.2 I can reproduce your error and fix it with quarantine-attribute-removal (I haven't tried on 14.3 yet), so here's how to do that, plus some context:

When you download stuff with Safari it sets some metadata on whatever it was you downloaded to say that it's an internet download, which are initially restricted by the OS (that's the source of the 'this application was downloaded from the internet, do you want to open it?' warning you get with apps downloaded with Safari.

(You can see this metadata with the xattr command: xattr libsaxon-HEC-mac-aarch64-v12.4.2.zip)

You can remove the quarantine metadata using the xattr command, either from the .zip like so:

xattr -d com.apple.quarantine libsaxon-HEC-mac-aarch64-v12.4.2.zip

or from the expanded contents of the archive (if you've already expanded the .zip) with:`

xattr -dr com.apple.quarantine libsaxon-HEC-mac-aarch64-v12.4.2

By default, the build script for in the command directory says that the executableit builds should look for the .dylib in the path ../libs/darwin relative to the exectuable. (That is, the paths as they are in the .zip.) So, if you expand the zip, remove the com.apple.quarantine extended attribute, and build it using build64-mac.sh it ought to work.

I think that there's also a general documentation problem here too: I have a feeling that /usr/local/lib is no longer (as of a recent OS update) a sensible place to install .dylibs, and we introduced a change to the way we build the .dylib to make it more reliable to link against a path you want, rather than a path we choose. I need to investigate the first, and write up the second part more usefully...

I'm just updating to 14.3 myself, and then I should be able to verify that nothing else is on.

Thanks, Matt, using xattr -dr for that com.apple.quarantine attribute and also doing sudo xattr -d com.apple.quarantine /usr/local/lib/libsaxon-hec-12.4.2.dylib now that I had the DYLD_LIBRARY_PATH set finally removed all that dialogue permission/security popups and I can run the commands or the sample of C++ of SaxonC fine.

I am pretty sure I downloaded with Google Chrome, I think, so I guess it is just how browsers behave on MacOs (14), not just a Safari thing.
