Compiling iOS version of Librtmp+openssl

http://blog.csdn.net/cjj198561/article/details/28955461

Compiling librtmp requires you to compile OpenSSL first, because Librtmp relies on OpenSSL

First compile OpenSSL:

Save the following as a shell script:

#!/bin/sh

version= "1.0.1h" #指明openssl的版本信息, such as the download is openssl-1.0.1h.tar.gz then for the fill 1.0.1h

sdkversion= "7.1" #指明ios SDK version number, the latest is 7.1, unclear classmate can ls/applications/xcode.app/contents/developer/platforms/ iphoneos.platform/developer/sdks/iphoneos7.1.sdk/, see if your IPHONEOS7.1.SDK is 7.1.

Currentpath= ' pwd '
archs= "i386 armv7 armv7s arm64"
Buildpath= "${currentpath}/build"
Libpath= "${currentpath}/lib"
Includepath= "${currentpath}/include"
Srcpath= "${CURRENTPATH}/SRC"
Libssl= "LIBSSL.A"
Libcrypto= "LIBCRYPTO.A"
Developer= ' Xcode-select-print-path '

if [!-D "$DEVELOPER"]; Then
echo "Xcode path isn't set correctly $DEVELOPER does not exist (most likely because of Xcode > 4.3)"
echo "Run"
echo "sudo xcode-select-switch <xcode path>"
echo "For default installation:"
echo "sudo xcode-select-switch/applications/xcode.app/contents/developer"
Exit 1

Save script, add Execute permissions for script (chmod +x script name)

Run the script

No accident can be compiled successfully, if it fails, you can open the log file to see the reason for the failure.

After compiling successfully, the Lib file and include copy to your Librtmp directory (can create a new empty librtmp directory), in the Librtmp directory also write a shell script, the script is as follows:

#!/bin/sh

sdkversion= "7.1" #这里跟openssl的地方是一个意思

Currentpath= ' pwd '
archs= "i386 armv7 armv7s arm64"

Libpath= "${currentpath}/lib" #这里就是刚才拷贝过来的目录, do not modify, because the final generation of librtmp also placed below this
Includepath= "${currentpath}/include" #这里就是刚才拷贝过来的目录, do not modify, because the final generation of librtmp also placed below this
