QRencode 編譯依賴libzlib,libpng:
Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR)
Could NOT find PNG (missing: PNG_LIBRARY PNG_PNG_INCLUDE_DIR)
GETOPT_LIBRARIES
linked by target "qrenc" in directory E:/sparrow/code/client/sparrow_live/qrencode-4.0.0
這篇文章主要闡述png庫的編譯。
1）下載下傳png源碼 https://sourceforge.net/projects/libpng/files/libpng16/1.6.34/lpng1634.zip/download?use_mirror=jaist&download=
2）解壓源檔案，解壓出源碼 建立build檔案夾，cmake出lpng庫工程。
這時出現了問題
CMake Error at C:/Program Files/CMake/share/cmake-3.8/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR)
把剛剛生成的zlib加載進去就可以了
生成了libpng庫工程
3）打開libpng.sln
4)這樣就生成了所需要的庫
附加：libpng源碼，32，64位下載下傳位址 http://download.csdn.net/download/fxbjye/10186394
