What steps will reproduce the problem?

Compile using cmake .


What is the expected output? What do you see instead?

During compilation, the following error message occurs:
error: ‘int_p_NULL’ was not declared in this scope


What version of the product are you using? On what operating system?

gilviewer revision 120
Arch Linux, kernel 2.6.35
gcc 4.5
libpng 1.4.3


Please provide any additional information below.

This is an issue within the GIL extension; libpng 1.4 dropped declaration for 
int_p_NULL; the following needs to be added within GIL or before inclusion of 
GIL headers:
#define int_p_NULL (int*)NULL

Reference: http://libpng.sourceforge.net/ANNOUNCE-1.4.1.txt

Correction: png_infopp_NULL also needs to be declared.
#define png_infopp_NULL (png_infopp)NULL
#define int_p_NULL (int*)NULL

Thanks for that, the problem still exist and we have to add :

#define png_infopp_NULL (png_infopp)NULL
#define int_p_NULL (int*)NULL
#define png_bytep_NULL (png_bytep)NULL

and change png_'set_gray_1_2_4_to_8(png_ptr)' to 
'png_set_expand_gray_1_2_4_to_8(png_ptr)'

Regards
