Installing OpenSSL library for Xcode

Question

I have installed OpenSSL in xcode for receipt validation, but it doesn't work.

I download openssl.xcodeproj and openssl-1.0.1f. I extract openssl-1.0.1f and add openssl.xcodeproj to my project.

I edit the Header Search Path to :

 /Users/marko/Documents/Razvoj/BIView\ Mobile\ New\ Version/openssl/include/openssl

I added libcrypto.a in Target Dependencies under Build Phases

and added libcrypto.a in Link Binary With Libraries

as was described in http://atastypixel.com/blog/easy-inclusion-of-openssl-into-iphone-app-projects/.

But when I build project it stops with error :

clang: error: no such file or directory: '/Users/ .... -bmgslnakszsfovecplbzoslykrxo/Build/Products/Debug-iphoneos/libcrypto.a'

Why ?

Solution 1

OK, how to build and install it....

It might be easier to use a pre-built version of OpenSSL for iOS. You can find one at this Github account. The OpenSSL from that Github are multi-arch. They have ARMv7, ARMv7s, ARM64, and i386. That means they work with devices and simulators.

Download either OpenSSL 1.0.1e or 1.0.1f. Install it in a location like /usr/local/ssl/ios.

Then, add the headers to your Xcode project. They are located in /usr/local/ssl/ios/include:

Finally, add the multi-arch libs (libcrypto.a and libssl.a) to your Xcode project. They are located in /usr/local/ssl/ios/lib:

Solution 2

You need to add the library as a Framework. See this question: how to add an existing framework in Xcode 5.

Its OK to add the OpenSSL libraries under Frameworks. Its how things are done under Apple/Xcode.

I use the Absolute Path like in the image below because Crypto++, OpenSSL, etc are installed in /usr/local. The image below is a screen capture I have handy of Crypto++, and not OpenSSL's libcrypto.a or libssl.a. But the same applies to all libraries.

My problem is that I have openSll.xcodeproj, and openSLL.tar.gz. If I have openSll.framework I would know what to do.

I don't know what openSll.xcodeproj is. openssl-1.0.N.tar.gz is the source code. Is that what you have? If so, you need to unpack, build, and install it.

OK, how to build and install it. I am new at this stuff and I will be really thankfull if you could help me.

[jww]

See Compilation and Installation on the OpenSSL wiki. There's also a bunch of INSTALL.<platform> readme's in the root of the source code. The 5 second fly-by: ./config; make all; sudo make install. You'll then find it in /usr/local/ssl.

[Marko Zadravec]

in terminal in navigate to file where openssl-1.0.N.tar.gz is located and write your script. It says make: *** [links] Error 1 making all in crypto... /bin/sh: /Applications/Xcode: No such file or directory make: *** [build_crypto] Error 1 Password: and I dont know whitch password I should write.

You have to cross-compile OpenSSL for iOS after setting your environment (my bad, I forgot to mention it). See the answer below.

[Marko Zadravec]

in /usr/local/ I have maps : bin, etc, include, lib, man, Qt, sbin, share, textlive. Do you mean to create new file named ssl, but then libcrypto.a and libssl.a would not be there.

[jww]

Do a mkdir -p /usr/local/ssl/ios. Then you will have it.

[Marko Zadravec]

mkdir: /usr/local/ssl/ios: Permission denied

[Marko Zadravec]

I would be more than happy if You could show me how to make .a or .framework from .tar.gz because after that I have another lib te extract (asn1c.tar.gz). :D But it this field (and terminal in general) I don't have much experience so be patient and go slow. I really appreciate your time.

[jww]

See the various scripts provided with the iOS tarball. That's what I use to build them. build-all.sh calls the other scripts in turn for a particular platform. The other scripts set the environment and then invoke config, make, etc. Your mileage may vary for asn1c.tar.gz.

[jww]

"... permission denied... " - sudo mkdir -p /usr/local/ssl/ios.

[Marko Zadravec]

I try build-all-for-ios.sh but it gives me : **************************************** sed: Configure: No such file or directory sed: Makefile.org: No such file or directory sed: Makefile.org: No such file or directory sed: Makefile.org: No such file or directory **************************************** iPhoneSimulator, -i386 CONFIG_OPTIONS=no-asm no-shared --openssldir=/usr/local/ssl/ios build-all-for-ios.sh: line 42: ./config: No such file or directory make: *** No rule to make target clean'. Stop. cp: ./libcrypto.a: No such file or directory . make:***No rule to make target clean.Stop.`

In the middle is more but I couldn't paste all of it

[jww]

You should ask another question since this is different from your original question.

[Marko Zadravec]

I posted new question pleas look and answer

In recent versions of Xcode, putting the location in User Search Path results in errors about using angled brackets instead of quotes for the filenames in #include statements. Do what the answer says, but put the location in Header Search Paths instead.
