Attempt to install PYQT5 failed

Card in: Compile qtbase/src/gui/image/qpnghandler.cpp times wrong:

. obj/qpnghandler.o:in function ' Qpnghandlerprivate::readpngheader () ':
Qpnghandler.cpp: (. text+0xbe2): Undefined reference to ' PNG_SET_LONGJMP_FN '
. obj/qpnghandler.o:in function ' Qpngimagewriter::writeimage (qimage const&, int, QString const&, int, int) ':

. obj/qpnghandler.o:in function ' Qpnghandlerprivate::readpngimage (qimage*) ':
Qpnghandler.cpp: (. text+0x30cc): Undefined reference to ' PNG_SET_LONGJMP_FN '
Collect2:ld returned 1 exit status

I thought it was not added-lpng library, in the makefile add-lpng, the results are still not resolved.

Open Qtbase/src/gui/image/qpnghandler.cpp File:

#if  PNG_LIBPNG_VER >= 10400 && PNG_LIBPNG_VER <= 10502          && defined (png_pedantic_warnings_supported)/*     versions 1.4.0 to 1.5.2 of libpng declare png_ Longjmp_ptr to    have a noreturn attribute if png_pedantic_ warnings_supported    is enabled, but most declarations of  longjmp in the wild do    not add this attribute.  This causes problems when the png_jmpbuf    macro expands &NBSP;TO&NBSP;CALLING&NBSP;PNG_SET_LONGJMP_FN&NBSP;WITH&NBSP;A&NBSP;MISMATCHED&NBSP;&NBSP;&NBSP;&NBSP;LONGJMP,  as compilers such as clang will treat this as an error .      To work around this we override the png_jmpbuf macro to cast     longjmp to a png_longjmp_ptr.*/#   undef png_jmpbuf #   ifdef png_setjmp_supported#       define png_ Jmpbuf (png_ptr)               (*png_set_longjmp _FN ((png_ptr),  (png_longjmp_ptr) longjmp, sizeof (jmp_buf))) #   else#        define png_jmpbuf (png_ptr)                (LIBPNG_WAS_COMPILED_WITH__PNG_NO_SETJMP) #   endif#endif

What should I do with it?

Here are the calls to Png_jmpbuf:

if (setjmp (Png_jmpbuf (png_ptr))) {png_destroy_read_struct (&png_ptr, &info_ptr, &end_info);        png_ptr = 0;        Amp.deallocate ();        state = Error;    return false; }
