编译时的configure文件怎么修改

[weixin_38060694]

在openssl的makefile文件中：
CC= cc
CFLAG= -O

在openssl的configure文件中：
# iPhoneOS/iOS
"iphoneos-cross","llvm-gcc:-O3 -isysroot \$(CROSS_TOP)/SDKs/\$(CROSS_SDK) -fomit-frame-pointer -fno-common::-D_REENTRANT:iOS:-Wl,-search_paths_first%:BN_LLONG RC4_CHAR RC4_CHUNK DES_UNROLL BF_PTR:${no_asm}:dlfcn:darwin-shared:-fPIC -fno-common:-dynamiclib:.\$(SHLIB_MAJOR).\$(SHLIB_MINOR).dylib",


怎么修改configure文件，执行./configure后能让makefile变成：
CC = llvm-gcc -arch arm64
CFLAG = llvm-gcc -arch arm64-O3 -isysroot \$(CROSS_TOP)/SDKs/\$(CROSS_SDK) -fomit-frame-pointer -fno-common::-D_REENTRANT:iOS:-Wl,-search_paths_first%:BN_LLONG RC4_CHAR RC4_CHUNK DES_UNROLL BF_PTR:${no_asm}:dlfcn:darwin-shared:-fPIC -fno-common:-dynamiclib:.\$(SHLIB_MAJOR).\$(SHLIB_MINOR).dylib 中的\$(CROSS_TOP)/SDKs/\$(CROSS_SDK)变成具体路径

./configure --help 看看 或者看看脚本怎么选择 iphoneos-cross
