[Gmod-ajax] Problems when compiling wig2png of JBrowse

[wangdan <wan...@16...>]

Hello, everyone!
I've installed libpng12-0 and libpng12-dev on my OS ubuntu 11.10
i386.There's something wrong when I compiling wig2png. I've run
configure first and I've installed g++ 4.6 and make tools using "sudo".
It showed the errors in the terminal:
/tmp/ccNbdLZq.o: In function `write_png_file(char const*, int, int,
unsigned char**, png_color_struct*, int, int)':
/var/www/jbrowse-1.2.1/src/wig2png.cc:47: undefined reference to

/var/www/jbrowse-1.2.1/src/wig2png.cc:55: undefined reference to
`png_destroy_write_struct'

Actually I've tried different version of libpng instead. I compiled and
installed libpng15 and tried wig2png again but it didn't work yet.
What's the problem? How to solve this?
Thank you very much!
