在Windows上構建PoDoFo-尚未解決的外部問題

Question

我正在嘗試構建PoDoFo，但與OpenSSL相關的鏈接器錯誤很少（我認為）。 我嘗試構建它（OpenSSL），但是它太復雜了，因此我從http://slproweb.com/products/Win32OpenSSL.html下載了Win64 OpenSSL v1.0.1e。

我從以下代碼制作了Visual Studio解決方案：

del cmakecache.txt
set FTDIR=D:\Iwan\Projekty\PDF_projekt\freetype-2.4.11
set FTLIBDIR=D:\Iwan\Projekty\PDF_projekt\freetype-2.4.11\objs\win32\vc2010
set JPEGDIR=D:\Iwan\Projekty\PDF_projekt\jpeg-9
set ZLIBDIR=D:\Iwan\Projekty\PDF_projekt\zlib127-dll
set LIBCRYPTODIR=C:\OpenSSL-Win64
cmake -G "Visual Studio 10" ..\podofo-0.9.2 -DCMAKE_INCLUDE_PATH="%FTDIR%\include;%JPEGDIR%\include;%JPEGDIR%;%ZLIBDIR%\include;%LIBCRYPTODIR%\include;%LIBCRYPTODIR%\include\openssl" -DCMAKE_LIBRARY_PATH="%FTLIBDIR%;%FTDIR%\lib;%JPEGDIR%\lib;%JPEGDIR%;%ZLIBDIR%\lib;%LIBCRYPTODIR%\lib\VC" -DPODOFO_BUILD_SHARED:BOOL=TRUE -DFREETYPE_LIBRARY_NAMES_DEBUG=freetype2411MT_D -DFREETYPE_LIBRARY_NAMES_RELEASE=freetype2411MT -DLIBCRYPTO_LIBRARY_NAMES_DEBUG=libeay32MDd -DLIBCRYPTO_LIBRARY_NAMES_RELEASE=libeay32MD

我不確定應該在選項中添加哪個庫，但是嘗試了libeay32MD，sleay32MD，libeay32MT，ssleay32MT，libeay32和ssleay32。

當我嘗試編譯創建的解決方案時，出現以下鏈接器錯誤：

我正在嘗試將其編譯2天，但是我什么都沒做，而且在互聯網上找不到任何東西。

您需要自己構建OpenSSL。 並沒有那么復雜-這是相關的命令列表，取自與源代碼捆綁在一起的install.w64文件：

 > perl Configure VC-WIN64A
 > ms\do_win64a
 > nmake -f ms\ntdll.mak
 > cd out32dll
 > ..\ms\test

此處未提及的內容應在Visual Studio的命令提示符（“工具”菜單）中運行。 Perl在此處不可見，因此您應該首先運行命令：

set path=%path;c:\perl\bin
