Hi again,
Everything compiles with the --no-png flag set. Otherwise I get the
following :
format/png.c.fcs: In member function `Ruby FormatPNG::frame(int,Ruby*)':
format/png.c.fcs:82: error: cannot convert `uint32*' to `png_uint_32*' for
argument `3' to `png_uint_32 png_get_IHDR(png_struct*,
png_info*, png_uint_32*, png_uint_32*, int*, int*, int*, int*, int*)'
make: *** [format/png.o] Error 1
But I get this error when starting GridFlow :
we are using Ruby version 1.8.1
(done)
[RangeError] [integer 45728535928 too big to convert to `int']:
(eval):8:in `gf_bridge_init'
ERROR: Cannot load GridFlow-for-Ruby (gridflow.so)
Thank you for committing the other changes quickly,
Alexandre
