dlopen(libmysqlclient.dylib, 1): image not found

Setting LD_LIBRARY_PATH nor DYLD_LIBRARY_PATH in $HOME/.bashrc worked for me when using PostgresApp on Mac OSX. It seems to ignore these environment variables when starting the helper app on login.

However, copying the file libmysqlclient.XYZ.dylib from MySQL's download to /usr/local/lib/libmysqlclient.dylib and restarting PostgesApp solved this problem for me. This works because the dlopen() system call as a final resort also looks into /usr/local/lib, as long as environment variable DYLD_FALLBACK_LIBRARY_PATH is not set.

Read man dlopen for more info.

You need to export the DYLD_LIBRARY_PATH on Mac OS

export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/

All went well.

I tried:
CREATE EXTENSION mysql_fdw;

I Got:
ERROR: failed to load the mysql query:
dlopen(libmysqlclient.dylib, 1): image not found
HINT: export LD_LIBRARY_PATH to locate the library

Still no luck..

export DYLD_LIBRARY_PATH=/usr/local/mysql-connector-c-6.1.5-osx10.7-x86_64/lib

/Applications/Postgres.app/Contents/Versions/9.4/bin > ./psql
psql (9.4.0)
Type "help" for help.

pim=# CREATE EXTENSION mysql_fdw;

It should work, please do these steps.

1 - Stop the postgres server
2 - On the same shell export DYLD_LIBRARY_PATH=/usr/local/
mysql-connector-c-6.1.5-osx10.7-x86_64/lib
3 - Start postgres server
4 - ./psql
5 - CREATE EXTENSION mysql_fdw;

Please send me listing of /usr/local/mysql-connector-c-6.1.5-osx10.7-x86_64/lib
folder.

ls /usr/local/mysql-connector-c-6.1.5-osx10.7-x86_64/lib

It works! Thanks! I forgot to restart the server before...

[benmadin]

Can I just add... after some frustration, on Mac OS X Yosemite it is not enough to sudo launchctl unload and load postgres to effect this - you actually have to su -m _postgres and use pg_ctl to stop and start.

cheers
