GnuTLS-GMP-Nettle-for-iOS

Overview:

GnuTLS 3.1.* build scripts for iPhoneOS and iPhoneSimulator using official XCode toolchain and SDK from Apple. Please read all this readme before you start.

Result files will be in created lib/ and include/ directories for i386 and armv7 architectures. To use those libraries, include the library from lib/ directory and headers from include/.

If you have any problem don't hesitate to contact to me.

Note for GnuTLS 3.2.* version:

I couldn't compile 3.2.* version (tested 3.2.8) of GnuTLS because (I think) it needs special pkg-config binaries to find Nettle library.

License:

Under LICENSE file

Install:

1. build-gmp
2. build-nettle
3. If you don't have XZ utils in system => build-xz
4. build-gnutls
5. You have all libraries in lib/ and include/ directories

Output structure:

Build scripts will create in current folder with additional structure:

• build/ -configured build files for every library and architecture
• lib/ -output libs (merged for all configured architectures)
• include/ -output headers
• src/ -source files (extracted from tarballs)
• tar/ -tarball files
• usr/ -build files for every configured platform (includes, libs, shares, manuals)

Tested versions (without errors) on:

• OSX 10.8.5
• Xcode 5.0
• GMP 5.1.3
• Nettle 2.7.1
• XZ 5.0.5
• GnuTLS 3.1.18

Usefull tools:

• xcrun - to locate development tools and properties for specyfied platform

  • eg: Locate C compiler for iPhoneOS: xcrun find -sdk iphoneos cc

• lipo - to create, merge and operate on files

  • eg: Merge libraries with different architectures into one universal file: lipo -create usr.i386/lib/libgmp.a usr.armv7/lib/libgmp.a -output lib/libgmp.a

• uname - print system name

  • eg: Print actual architecture: uname -m
