Following the documentation on how to install MySQL Router on MacOSX, I have successfully compiled it and installed it in /usr/local/bin.

When I run it with the -h or -v options it runs fine, e.g:

$ sudo mysqlrouter -v
MySQL Router v2.0.2 on OS X v10.11 (64-bit) (GPL community edition)

When trying to use the fabric plugin however, I get a linking issue - apparently the @rpath variable doesn't contain the correct path.

$ sudo mysqlrouter 
Logging to /var/log/mysqlrouter/mysqlrouter.log
Error: dlopen(/usr/local/lib/mysqlrouter/fabric_cache.so, 9): Library not loaded: @rpath/logger.so
  Referenced from: /usr/local/lib/mysqlrouter/fabric_cache.so
  Reason: image not found

Please see below for attempted fixes and their results

Thanks a lot

How to repeat:
Here is some additional information:

$ otool -L /usr/local/lib/mysqlrouter/fabric_cache.so
	@rpath/fabric_cache.so (compatibility version 0.0.0, current version 0.0.0)
	@rpath/logger.so (compatibility version 0.0.0, current version 0.0.0)
	@rpath/libmysqlrouter.1.dylib (compatibility version 1.0.0, current version 0.0.0)
	libmysqlclient.18.dylib (compatibility version 18.0.0, current version 18.0.0)
	@rpath/libmysqlharness.0.dylib (compatibility version 0.0.0, current version 0.0.0)

	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1226.10.1)

$ ls -iAlF /usr/local/lib/mysqlrouter/
total 1848

37927548 -rwxr-xr-x  1 root  wheel  396832 12 Feb 13:25 routing.so*

Suggested fix:
When replacing the @rpath with hard-coded locations in the cmake files I get past those initial errors but then arrive to others about the location of the mysql Harness libraries

Since OS X 10.11 I am always using -DWITH_STATIC=yes option for building Router.
Can you check with that option?

Posted by developer:
Fixed as of the upcoming MySQL Router 2.0.4 release, and here's the changelog entry:

On OS X, linking Router to Fabric would fail to function by default due to
linking problems.

Thank you for the bug report.

Thank you very much - is there a way to download this upcoming version already, such as a git repo? Or is there a planned release date?
