The reason is that version 1.2 assumes sizeof(unsigned long int)==4, which is not true on Linux x86_64 Message from GCC: error: cannot convert 'uint32_t* {aka unsigned int*}' to 'png_uint_32* {aka long unsigned int*}' for argument '3' to 'png_uint_32 png_get_pHYs(png_structp, png_infop, png_uint_32*, png_uint_32*, int*)' , &res_x, &res_y,&unit); In version 1.6 (I use that version when compiling on windows) #if INT_MIN < -2147483646 && INT_MAX > 2147483646 typedef int png_int_32; #elif LONG_MIN < -2147483646 && LONG_MAX > 2147483646 typedef long int png_int_32; #else # error "libpng requires a signed 32 bit (or more) type" #endif #if UINT_MAX > 4294967294 typedef unsigned int png_uint_32; #elif ULONG_MAX > 4294967294 typedef unsigned long int png_uint_32; #else # error "libpng requires an unsigned 32 bit (or more) type" #endif Clearly, this bug is fixed in version 1.6. I could install my own libpng, but since this is a very central library I feel that it could be risky and I do not have time to recompile the hole system just for an old library. Suggestion: Fix this for version 14.10 (it strange that a newer libpng did not enter 14.04 LTS) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libpng/+bug/1348144/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
