Live555 (RTP/RTSP) on armv7s

Question

it is possible to use live555 lib with armv7s? Becasue I try to compile it with config

# Change the following version number, if necessary, before running "genMakefiles iphoneos"
IOS_VERSION =       7.0

DEVELOPER_PATH =    /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer
TOOL_PATH =     $(DEVELOPER_PATH)/usr/bin
SDK_PATH =      $(DEVELOPER_PATH)/SDKs
SDK =           $(SDK_PATH)/iPhoneOS$(IOS_VERSION).sdk
COMPILE_OPTS =          $(INCLUDES) -I. $(EXTRA_LDFLAGS) -DBSD=1 -O2 -DSOCKLEN_T=socklen_t -DHAVE_SOCKADDR_LEN=1 -D_LARGEFILE_SOURCE=1 -D_FILE_OFFSET_BITS=64 -fPIC -arch armv7s --sysroot=$(SDK)
C =                     c
C_COMPILER =            $(TOOL_PATH)/gcc
C_FLAGS =               $(COMPILE_OPTS)
CPP =                   cpp
CPLUSPLUS_COMPILER =    $(TOOL_PATH)/g++
CPLUSPLUS_FLAGS =       $(COMPILE_OPTS) -Wall
OBJ =                   o
LINK =                  $(TOOL_PATH)/g++ -o 
LINK_OPTS =             -L. -arch armv7s --sysroot=$(SDK) -L$(SDK)/usr/lib/system
CONSOLE_LINK_OPTS =     $(LINK_OPTS)
LIBRARY_LINK =          libtool -s -o 
LIBRARY_LINK_OPTS =
LIB_SUFFIX =            a
LIBS_FOR_CONSOLE_APPLICATION =
LIBS_FOR_GUI_APPLICATION =
EXE =

then I try copy&paste program testMP3Reciver to my iOS project (yes I use .mm as postfix instead of .m, and include every header is needed), but still I got 14 errors Undefinded symbols for architecture armv7s

My code:

So I ask again, it's even posible to use live555 on armv7s? Maybe I should use another lib?

Solution/Update

I have to throw away armv7s, instead of it I use this project to create fat lib for iOS.

Step-by-step solution:

1. Clone this project git clone [email protected]:weevilgenius/live555-ios.git

2. Build lib, and copy to your project. At start I was have problem with finding compiled lib. So for those who don't know how to find it. After building lib in Xcode file tree open folder Products and right-click on libLive555.a then select "Show in Finder".

3. Add to your project every .hh. Those files are in folder include in every subfolder of folder Live555. Now everything should be just fine :)
