librtmp build for iOS
http://www.davideccher.com/blog/wordpress/building-librtmp-for-ios/
mkdir openssl cd openssl curl http://www.openssl.org/source/openssl-1.0.1e.tar.gz -O openssl-1.0.1e.tar.gz tar xfz openssl-1.0.1e.tar.gz
We’ll build all the release in the tmp folder. Start to configure it for armv6.
? mkdir openssl-1.0.1e-armv6 cd openssl-1.0.1e ./configure BSD-generic32 --openssldir=../openssl-1.0.1e-armv6 Now we has to edit Makefile and change
?
/Applications/Xcode.app/Contents/Developer/usr/bin/gcc -arch armv6
This links are valid for my buildsystem, using SDK 5.0. Change it to build for other buildsystem.
At this point we are ready to build.
? make make install Now in /tmp/openssl-1.0.0g-armv6 we have the builded lib.
We do the same for armv7 and i386:
?
cd .. mkdir openssl-1.0.1e-armv7 cd openssl-1.0.1e ./configure BSD-generic32 --openssldir=../openssl-1.0.1e-armv7
CC= /Applications/Xcode.app/Contents/Developer/usr/bin/gcc -arch armv7
make make install
mkdir openssl-1.0.1e-i386 cd openssl-1.0.1e ./configure BSD-generic32 --openssldir=../openssl-1.0.1e-i386
CC= /Applications/Xcode.app/Contents/Developer/usr/bin/gcc -arch i386 make make install
At this point we can create an universal library using lipo.
? cd .. mkdir include cp -r /tmp/openssl-1.0.1e-i386/include/ include/ mkdir lib
lipo /tmp/openssl-1.0.0g-armv6/lib/libcrypto.a /tmp/openssl-1.0.0g-armv7/lib/libcrypto.a /tmp/openssl-1.0.0g-i386/lib/libcrypto.a -create -output lib/libcrypto.a lipo /tmp/openssl-1.0.0g-armv6/lib/libssl.a /tmp/openssl-1.0.0g-armv7/lib/libssl.a /tmp/openssl-1.0.0g-i386/lib/libssl.a -create -output lib/libssl.a Now we have in our include and lib folder the the universal library of openssl.
To build librtmp for ios we build the three version of library like for openssl.
Starting cloning the last release
? mkdir librtmp cd librtmp git clone git://git.ffmpeg.org/rtmpdump rtmpdump
To build the armv6 version of library make a copy of the source:
? cp -r rtmpdump rtmpdump-armv6 cd rtmpdump-armv6/librtmp
export CROSS_COMPILE=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ export XCFLAGS="-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk -I/tmp/openssl/include/ -arch armv6" export XLDFLAGS="-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk -L/tmp/openssl/lib -arch armv6 " make SYS=darwin make SYS=darwin prefix=/tmp/librtmp-armv6 install Change the path to export using the correct system build path and the path of the openssl lib build before.
For the armv7
? cp -r rtmpdump rtmpdump-armv7 cd rtmpdump-armv7/librtmp
export CROSS_COMPILE=/Applications/Xcode.app/Contents/Developer/usr/bin/ export XCFLAGS="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -I/tmp/openssl/include/ -arch armv7" export XLDFLAGS="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -L/tmp/openssl/lib -arch armv7" make SYS=darwin make SYS=darwin prefix=/tmp/librtmp-armv7 install
export CROSS_COMPILE=
For simulator
? cd .. cp -r rtmpdump rtmpdump-i386 cd rtmpdump-i386/librtmp edit Makefile con CC=$(CROSS_COMPILE)gcc -arch i386 export CROSS_COMPILE=/Applications/Xcode.app/Contents/Developer/usr/bin/
export XCFLAGS="-I/tmp/openssl/include/ -arch i386" export XLDFLAGS="-L/tmp/openssl/lib -arch i386"
make SYS=darwin make SYS=darwin prefix=/tmp/librtmp-i386 install At this point we can create an universal library using lipo.
? mkdir include cp -r /tmp/librtmp-i386/include/librtmp include/ mkdir lib lipo /tmp/librtmp-armv6/lib/librtmp.a /tmp/librtmp-armv7/lib/librtmp.a /tmp/librtmp-i386/lib/librtmp.a -create -output lib/librtmp.a
