I'm having trouble getting my head around installing externals in general and this one more specifically. I've downloaded ratts from http://www.ling.uni-potsdam.de/~moocow/projects/pd/

Opened the readme, figured I'd have to use the terminal to install it. Used the cd command to find the ratts folder in my downloads folder. then wrote ./configure then hit enter and i get this.

Bender:ratts-0.08 ossian$ ./configure

checking for gawk... no
checking for mawk... no

checking whether make sets $(MAKE)... no
checking for gcc... no
checking for cc... no
checking for cl.exe... no
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details.

What did I do wrong? I'm a huge noob when it comes to these sort of things.

You need gcc to compile. I believe on OSX you have to install XCode to get all the developer tools needed for compiling.

downloaded gcc from https://github.com/kennethreitz/osx-gcc-installer as it's not included in Xcode anymore apparently.

so tried again and got a warning "WARNING: could not find PD header file 'm_pd.h' -- things might get ugly." and then tried make and makefile resulting in lots of errors. here's the log:

m_pd.h is the header file required by externals for them to work correctly. It contains the functions that let them interact with Pd itself. It's typically distributed with Pd; you might want to search your system for it. If not, you can find it in the source code (look for the version you need on puredata.info). If you take m_pd.h and put it in the same folder as that external, it will likely find it.

found the file, but it's not recognized... i've tried putting it in the ratts folder, the configure folder and the src folder without luck.
this is seriously starting to get on my nerves.

is compiling this the only way to get text-to-speech functionality in pd?
