Compile OpenCore-amr for iOS Projects

I really had a hard time compiling OpenCore-amr for my iphone application meant for ios 6.0.

Special thanks to all those people / websites who guided me and i was able to finish up the task.

Follow the steps and may be it could help you :

Step - 1 : I downloaded from http://kakola.googlecode.com/files/opencore-amr-0.1.2.tar.gz

Step - 2 : Place this folder on your macbook
               (i placed in a folder named Compile-Opencore)

Step - 3 : Open the Terminal

Step - 4 : Change the directory to move to the downloaded opencore-amr-0.1.2 directory
               $ cd /Users/Swati/Compile-Opencore/opencore-amr-0.1.2 

Step - 5 : Execute configure

              $ /Users/Swati/Compile-Opencore/opencore-amr

             -0.1.2/configure

This command will start Checking like : 

             checking for a BSD-compatible install... /usr/bin/install -c

             checking for gcc... gcc

             checking if libtool supports shared libraries... yes

             checking if gcc supports -c -o file.o... yes

             checking if gcc supports -c -o file.o... (cached) yes

etc...

Step - 6 : Call make

               $ make

Step - 7 : Call make install

               $ sudo make install 

               Password:

Step - 8 : Remember to check path of xcode

               $ xcode-select -print-path

               /Applications/Xcode.app/Contents/Developer

Step - 9 : Execute shell script

               $ /Users/Swati/Compile-Opencore/opencore-amr

              -0.1.2/build_osx.sh 

Step - 10 : configure library for armv7s

                $ <path_idz_configure.sh> <architecture> <ios_version>

                   <path_configure_opencore-amr-0.1.2>

                $ /Users/swatisrivastava/Documents/Swati/Compile

                  -Opencore/opencore-amr-0.1.2/idz_configure.sh armv7s 

                  6.0 /Users/Swati/Compile-Opencore/opencore-amr

                 -0.1.2/configure

Above step may result in errors like : 

configure: error: source directory already configured; run "make distclean" there first

make: *** No rule to make target `clean'.  Stop.

make: *** No targets specified and no makefile found.  Stop.

make: *** No rule to make target `install'.  Stop.

Step - 11 : Do cleaning if error occurs in Step - 9

                 $ make distclean

Step - 12 : Again configure for armv7s

                 $ /Users/Swati/Compile-Opencore/opencore-amr

                    -0.1.2/idz_configure.sh  armv7s 6.0 /Users/Swati/

                    Compile-Opencore/opencore-amr-0.1.2/configure

Step - 13 : Configure for armv7 also

                 $ /Users/Swati/Compile-Opencore/opencore-amr-0.1.2/

                     idz_configure.sh  armv7 6.0 /Users/Swati/Compile-Opencore

                     /opencore-amr-0.1.2/configure

Step - 14 : Configure for i386 also

                 $ /Users/Swati/Compile-Opencore/opencore-amr-0.1.2/

                     idz_configure.sh i386  6.0 /Users/Swati/Compile-Opencore/

                     opencore-amr-0.1.2/configure

Step - 15 : You can view the libraries here:

Inside your opencore-amr-0.1.2 folder : you can see 6 new folders :

build-iPhoneOS-armv7 and install-iPhoneOS-armv7

build-iPhoneOS-armv7s and install-iPhoneOS-armv7s

build-iPhoneSimulator-i386 and install-iPhoneSimulator-i386

goto install-iPhoneOs-armv7 folder >> lib folder >> here u can see library files specific to armv7 architecture namely : 

   a) libopencore-amrnb.a 

   b) libopencore-amrwb.a

Similarly u can get libraries of each architecture.

Step - 16 :  Command to create a single "Universal" .a library that contains the features of all 3 libraries

                  $ lipo -create 

                  <path_of_armv7_libopencore-amrnb.a>

                  <path_of_armv7s_libopencore-amrnb.a> 

                  <path_of_i386_libopencore-amrnb.a>

                  -output <path_universal_libopencore-amrnb.a>

                                                   &

                  $ lipo -create 

                  <path_of_armv7_libopencore-amrwb.a>

                  <path_of_armv7s_libopencore-amrwb.a> 

                  <path_of_i386_libopencore-amrwb.a>

                  -output <path_universal_libopencore-amrwb.a>

Hope it helps.

Enjoy compiling...
