hi guy,it can generate static library for MacOS but not iOS when i use the script,it always print ”Building openssl-1.0.2d for iPhoneOS 9.0 armv7“,lib folder is empty.

doesn't build either MacOS or iOS for me

Both built fine for me on OS X 10.10.5 with Xcode 7.0.1 installed.

@major1314 I have the same problem.

@major1314 and @tomassliz , did you check the log under the /tmp/openssl-1.0.2d-xxxxx.log ? (xxxxx is the platform like i386, armv7)

I have the same problem and I found it because of the path.

I build in /Users/myusername/Google Drive/openssl . However, it didn't work and i cannot build with the spacing in folder path. After I changed the folder to /Users/myusername/openssl and it was working fine.

For anyone using this, you can replace export CC=clang; with export CC=clang -fembed-bitcode; and ./Configure ios64-cross no-shared no-dso no-hw no-engine --prefix=/usr/local/openssl-ios64 with ./Configure ios64-cross no-shared no-dso no-hw no-engine no-asm --prefix=/usr/local/openssl-ios64. If you've already run a failing build make sure to make clean before trying again.

anyone tried enabling bitcode for Android while building openssl? I'm guessing this same script would work... does anyone know?
