If it doesn't work, let me know so I can update the instructions. I don't use Mac myself so I can't test. I made the instructions from an e-mail conversation with a very patient user :)
Install Fink.
Type this in a terminal:
fink install glib2-dev openssl100-dev
Save this header file in your home directory. Then type this in a terminal:
mkdir /usr/include/xchat
cp ~/xchat-plugin.h /usr/include/xchat/
Replace the following line:
$(CC) -shared $(OURLINKFLAGS) $(PLUGIN_OBJECTS) -o $@
$(CC) -shared -undefined suppress -flat_namespace $(OURLINKFLAGS) $(PLUGIN_OBJECTS) -o $@
You should now have everything needed to compile FiSHLiM. Download and unpack the source code. Type this into a terminal (change ~/fishlim-master
to the place where you unpacked the source):
cd ~/fishlim-master
make
sudo make install
Start XChat and set up your keys with /setkey secret
