Ok, so we need the headers
Fortunately you can download MAMP source form their website - this gives you a .dmg with lots of .tar.gz files, you just need the mysql one.
I tried just copying the include directory as it was - but loads of the header files have variables that need replacing.
Let's compile this thing
compilation uses cmake, so ensure you have that first.
tar zxvf mysql-5.5.9.tar.gz cd mysql-5.5.9 cmake . make mkdir /Applications/MAMP/include/ cp -r include/* /Applications/MAMP/include/ cp libmysql/*.dylib /Applications/MAMP/Library/lib
