我正在尝试编译可在线获得的代码Non-Local Means Denoising
当我编译源代码时,出现以下错误,我认为主要是由于libpng
:
g++ -L/opt/local/lib/ -L/usr/local/lib/ -L/usr/lib/x86_64-linux-gnu/ -fopenmp -lpng
-o nlmeans_ipol nlmeans_ipol.o io_png.o libauxiliar.o libdenoising.o mt19937ar.o
io_png.o: In function `io_png_write_raw':
io_png.c:(.text+0xe0): undefined reference to `png_create_write_struct'
io_png.c:(.text+0xf6): undefined reference to `png_create_info_struct'

io_png.c:(.text+0xe6a): undefined reference to `png_destroy_write_struct'
io_png.c:(.text+0xe80): undefined reference to `png_destroy_write_struct'
我遵循以下线程并将文件“libpng.a”放置在许多位置,但它没有帮助。
我在这里看到了类似的 libpng 问题,但没有帮助。
我正在使用 ubuntu 12.04。
谁能告诉我实际上可能出了什么问题?

这是完整的电话。它是一个make文件,上面的转储在命令提示符处显示的副本中。
