Re: NCARG libraries unable to locate cairo functions

Dear Mary,

Some additional information. After installing my own copy of cairo, the
cairo_move_to symbol is successfully found:

crstanl@ubuntu:~$ nm /usr/local/lib/libcairo.a | grep cairo_move_to
00001200 T INT_cairo_move_to
00001200 T cairo_move_to
         U INT_cairo_move_to

Regards,

Tan
