[Gmod-ajax] wig2png compile error

[常啸 <xc...@si...>]

hi,
I meet an error when compile wig2png after typing "make".

g++ -g -O2 -include src/config.h  -lpng  -o bin/wig2png src/wig2png.cc src/opts_list.cc
/tmp/cc1x8bbj.o: In function `write_png_file(char const*, int, int, unsigned char**, png_color_struct*, int, int)':
/var/www/html/jbrowse-jbrowse-9a1542d/src/wig2png.cc:59: undefined reference to `png_set_longjmp_fn'
collect2: ld returned 1 exit status

Can anyone tell me what's the problem?

Thanks,
Xiao

Hi Xiao,

Looks like gcc is not finding libpng - this is what the configure script 
is for. Try typing './configure' before 'make'.

Best wishes
Ian

Actually, scratch that - it looks like what's actually happening is 
you've got an old version of libpng. The missing function 
"png_set_longjmp_fn" was introduced in libpng 1.4.0

Autoconf can probably check this, but it currently doesn't. I've added a 
bug ticket:
http://jbrowse.lighthouseapp.com/projects/23792-jbrowse/tickets/63

In the meantime, the best thing for you to do is to install a newer 
version of libpng (>1.4)

Best wishes,
Ian
