嵌入式平台时按照网上的教程一步步来,到编译qvfb时出现错误qanimationwriter.cpp:(.text._ZN19QAnimationWriterMNGD2Ev[_ZN19QAnimationWriterMNGD5Ev]+0x9e): undefined reference to `png_write_chunk'
qanimationwriter.cpp:(.text._ZN19QAnimationWriterMNGD2Ev[_ZN19QAnimationWriterMNGD5Ev]+0xb0): undefined reference to `png_destroy_write_struct'
qanimationwriter.cpp:(.text._ZN19QAnimationWriterMNGD2Ev[_ZN19QAnimationWriterMNGD5Ev]+0x16e): undefined reference to `png_write_chunk'
collect2: ld 返回 1
make: *** [../../bin/qvfb]
错误 1
这是什么回事啊?
