After upgrading to OS X 10.11 El Capitan I'm having trouble with my libraries due to SIP and rootless:

dyld: Library not loaded: libmysqlclient.18.dylib

Referenced from: /Users/jose/Library/Developer/Xcode/DerivedData/myProject-dvophlqioihoungqcdkihvpzskee/Build/Products/Debug/SaDPeMAC.app/Contents/MacOS/myProject

Reason: image not found

I have changed the shared library identifier of libmysqlclient.18.dylib so that dyld looks for the binary relative to my application binary with this:

@executable_path/../Frameworks/libmysqlclient.18.dylib libmysqlclient.18.dylib

This works fine in my Mac Book Pro, but when a do the same in my iMac27 it throws the following error:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool: can't open file: libmysqlclient.18.dylib (No such file or directory)

I don't see any difference between my MBP and my iMac27. Any ideas?

Thanks in advance.

"Hi

I am having the same problem on a macbook air. Since I upgraded to El Capitan I can't run my mysql apps.

What did you do to change " the shared library identifier of libmysqlclient.18.dylib so that dyld looks for the binary relative to my application binary"?

It seems the upgrade removed the lib from /usr/lib, so I downloaded the latest build (10.8 osx and v6.1.6) and linked the library into /usr/lib. Initially, I got an error saying it could not connect to the socket /tmp/mysql.sock, so I fixed that by changing XAMMP configuration and that seems okay.

I now just get BAD_ACCESS when running the app, but no diagnostic of any use.

Thanks
