[cairo] The first cairo program complie error

[Woenkee Sohn]

I compiled the minimal cairo program on the cairo web.

There're UNDEFINED REFERENCE errors, thogh I could find those names from libcairo.a

Any ideas ?


Thank you, guys !!!

Woenkee.

cc -o hello `pkg-config --cflags --libs cairo` hello.c
