在Windows x64上安裝libpng時出錯

Question

我嘗試從http://libpng.org/pub/png/libpng.html安裝並重新安裝libpng 。 我需要使用它來使用bob （由python托管）進行面部驗證。 我按照第一步通過此答案安裝libzip和ziplib 。 但是我一直在出錯。

在這里，我列出了cmake的結果：

-- Building for: Visual Studio 14 2015
-- Found ZLIB: c:/Python27/work/libpng-1.6.26/lib/zlib.lib (found version "1.2.8")
-- Performing Test HAVE_LD_VERSION_SCRIPT
-- Performing Test HAVE_LD_VERSION_SCRIPT - Failed
-- Performing Test HAVE_SOLARIS_LD_VERSION_SCRIPT
-- Performing Test HAVE_SOLARIS_LD_VERSION_SCRIPT - Failed
-- Configuring done
-- Generating done
-- Build files have been written to: C:/Python27/work/libpng-1.6.26/libpng-1.6.26

然后，這是我在構建libpng.sln時得到的：

據我所知，我應該處理的是x64版本。 而且看起來cmake不能正確執行。 但是我對如何解決它一無所知。

Answer 1

我剛剛按照該答案中的步驟成功安裝了libpng。我認為您沒有正確安裝它，因為一旦我安裝不正確，我就會看到這些結果。

-執行測試HAVE_LD_VERSION_SCRIPT

-執行測試HAVE_LD_VERSION_SCRIPT-失敗

-執行測試HAVE_SOLARIS_LD_VERSION_SCRIPT

-執行測試HAVE_SOLARIS_LD_VERSION_SCRIPT-失敗

之后，我發現選擇CMAKE_INSTALL_PREFIX和libzip的CMAKE_PREFIX_PATH時出錯。 請注意，zlib和libzip應該安裝在同一路徑中。 並且libpng應該安裝在與前一個路徑相同的路徑中。

Answer 2

您確定使用CMake選擇了正確的生成器嗎？ 據我所知，如果要構建64位二進制文​​件，則需要選擇“ Visual Studio 14 2015 Win64”作為目標名稱。
