I've been struggling to get the whole thing to work in Pharo 2.0 So, here are some pointers: I am using Xcode 4.6.3 with command line tools installed. I used the MySQL 32-bit client: mysql-connector-c-6.1.0-osx10.7-x86.dmg I used opendbx stable-1.4 To compile OpenDBX itself in 32 bits mode and all, here is the script I used. [PhilMac:~/Documents/Smalltalk/2-MyWorkspaces/workspaceOpenDbx philippeback$] cat compileopendbxosx.sh PATH=/Applications/Xcode.app/Contents/Developer/usr/bin:${PATH} echo `which ld` CPPFLAGS="-m32 -I/usr/local/mysql-connector-c-6.1.0-osx10.7-x86/include" \ CXXFLAGS="-m32 -I/usr/local/mysql-connector-c-6.1.0-osx10.7-x86/include" \ CFLAGS="-m32 -I/usr/local/mysql-connector-c-6.1.0-osx10.7-x86/include" \ LDFLAGS="-m32 -L/usr/local/lib -L/usr/local/mysql-connector-c-6.1.0-osx10.7-x86/lib -lmysqlclient" \ ./configure --with-backends="mysql" --disable-utils LDFLAGS="-m32 -L/usr/local/mysql-connector-c-6.1.0-osx10.7-x86/lib" make make install Now, I had to copy the libraries of the mysql client into /usr/local/lib/ The client libraries were in /usr/local/mysql-connector-c-6.1.0-osx10.7-x86/lib (you can ln -s them if you do not want to copy). To test that things were okay, I created the sodbxtest user, database, and all in MySQL. Then let's make sure we can use that one: mysql -usodbxtest -psodbxtest sodbxtest And then went to stable-1.4/test and issued: ./odbxtest -b mysql -h localhost -p 3306 -d sodbxtest -u sodbxtest -w sodbxtest Which should work. You can open the MySQL Workbench Admin tab > server status tab and see the commands issued. I had to do a symlink in: : /usr/local/pharo/bin/pharo-vm/Pharo.app/Contents/MacOS/Plugins/ (where I have my pharo vm installed) so that: libopendbx.dylib was pointing to /usr/local/lib/libopendbx.dylib Then, start the image where you have loaded the OpenDBXDriver configuration and run the tests. You can get the configuration from the World menu > Configurations OpenDBXDriver (GuillermoPolito.20) I installed the configuration and then did: (ConfigurationOfOpenDBXDriver project version: #stable) load. All tests for the MySQL backend turned up green. Maybe someone can put the above things in the right sections on the DBXTalk site, I didn't got enough info for the OSX version. Next step is to try to get GLORP running, not sure I'll go that route. Phil
