It worked locally because that path existed in my build tree, but not in your
packaged environment.
and probably in any reviewers' local build, too if they tested from the local
build-tree instdir/ ..
This revealed a *hardcoded absolute path* embedded in the binary.
The issue happens because |$(SRCDIR)| expands to an absolute path at build
time, which gets permanently embedded in the binary.
[...]
The makefile was linking |librust_uno.so| using an absolute path, so the linker
recorded that full path in the binary’s *NEEDED* section.
Ah, I see. I wasn't explicitely aware that specifying a full path also
hardcodes the path.
Makes sense, though.
*
*Dev build:* The path existed → worked fine
*
*Packaged build:* The path didn’t exist → failed at runtime
Yeah, that sound like it.
Your |LD_LIBRARY_PATH| workaround confirmed this behavior, but it’s not a
sustainable solution.
Yup.
To fix this, I updated the makefile to use relative search paths and proper
*RPATH* configuration:
```
$(eval $(call gb_Library_add_ldflags,rust_uno-example,\
-Wl,-rpath,'$$ORIGIN' \
))
$(eval $(call gb_Library_add_libs,rust_uno-example,\
-L$(SRCDIR)/rust_uno/target/release -lrust_uno \
))
```
Now, when I check the result:
$ readelf -d workdir/Extension/rust_uno-example/root/rust_uno-example.uno.so
<http://rust_uno-example.uno.so> | grep NEEDED | grep rust
NEEDED [librust_uno.so]
It shows a *relative dependency* (|librust_uno.so|) instead of the previous
absolute path.
If this works on your side as well, I’ll prepare a patch for the next update to
include this fix.
So basically
