I was about to check iulib for libpng-1.4, but it failed on tiff instead. It looks to be checking zlib function from tiff's header (???) Output: scons: Reading SConscript files ... scons: warning: The Options class is deprecated; use the Variables class instead. File "/var/tmp/portage/media-libs/iulib-0.4/work/iulib-0.4/SConstruct", line 38, in <module> compiling for development (slower but safer) Checking for png_byte in C library png... yes Checking for jpeg_std_error() in C library jpeg... yes Checking for inflate() in C library tiff... no Please install the following required libraries (or equivalent): libtiff4-dev The part of SConstruct file it fails: ### check for required (dev-) libraries (automatically added to env LIBS) missing = "" if not conf.CheckLibWithHeader('png', 'png.h', 'C', 'png_byte;', 1): missing += " libpng12-dev" if not conf.CheckLibWithHeader('jpeg', 'jconfig.h', 'C', 'jpeg_std_error();', 1): missing += " libjpeg62-dev" if not conf.CheckLibWithHeader('tiff', 'tiff.h', 'C', 'inflate();', 1): missing += " libtiff4-dev"
