Hey,
As far as i know it should be possible to use the existing external OpenSSL library from cocos.
I’ve tried to add it to my CMake project:
#==================================================
#OpenSSL
if(ANDROID)
set(OPENSSL_PLATFORM_DIR android)
elseif(IOS)
set(OPENSSL_PLATFORM_DIR ios)
elseif(MACOSX)
set(OPENSSL_PLATFORM_DIR mac)
elseif(WINDOWS)
set(OPENSSL_PLATFORM_DIR win32)
elseif(LINUX)
set(OPENSSL_PLATFORM_DIR linux/64-bit)
else()
message(FATAL_ERROR "OpenSSL platform not specified or supported")
endif()
set(OPENSSL_PATH ${COCOS2DX_ROOT_PATH}/external/openssl)
include_directories(
${OPENSSL_PATH}/include/${OPENSSL_PLATFORM_DIR}
)
cocos_find_package(openssl OPENSSL REQUIRED)
cocos_use_pkg(${APP_NAME} openssl)
#set_target_properties(OpenSSL
#PROPERTIES IMPORTED_LOCATION ${OPENSSL_PATH}/prebuilt/${OPENSSL_PLATFORM_DIR}/libssl.a
#IMPORTED_LOCATION ${OPENSSL_PATH}/prebuilt/${OPENSSL_PLATFORM_DIR}/libcrypto.a)
#==================================================
But there are some strange linker issues
I’m trying to use the OpenSSL library and somehow it works fine except when I try to use AES_Encrypt and AES_Decrypt together. When I use one of them everything is fine, but both of them together generates following issue which i’ve never encountered before:
the 32-bit linker (C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.14.26428\bin\HostX86\x86\link.exe) failed to do memory mapped file I/O on lib\Debug\cocos2d.lib' and is going to restart linking with a 64-bit linker for better throughput 8> LINK : restarting link with 64-bit linkerC:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.14.26428\bin\Hostx64\x64\link.exe’
8> libtiff.lib(tif_win32.obj) : warning LNK4075: ignoring ‘/EDITANDCONTINUE’ due to ‘/INCREMENTAL:NO’ specification
8> LINK : fatal error C1905: Front end and back end not compatible (must target same processor).
8> LINK : fatal error LNK1257: code generation failed
There is this libtiff.lib in the middle but not sure why this would create issues when using the openssl functions.
VS info to this error: https://msdn.microsoft.com/en-us/library/414e6214.aspx
Maybe i’ve added the lib incorrectly to cmake?
