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
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

$ 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...
:)
