Hey Ry-
Is glib-2.0 a dependency? It seems like 2.0 is an old version of
glib. So ebb doesn't compile on leopard out of the box. What do I need
to install to make it work?
~/ebb > make
gcc -g -Wall `pkg-config --cflags glib-2.0` -I/opt/libev-2.01/include -
L/opt/libev-2.01/lib -c tcp.c -o tcp.o
Package glib-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `glib-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'glib-2.0' found
