[Linphone-developers] Building linphone-iphone w/ XCode4.2 / SL 10.6.8

[saumar]

Hi,
 
After cloning linphone-iphone.git, I followed the build procedure in README, 
but I'm unable to build Linphone for iOS.
The first problem is:
 
[ 11%] Building CXX object src/CMakeFiles/zrtpcppcore.dir/Zrtp.cpp.obj

(all arrows ^ above points to __except)

Calling make with arguments doesn't solve the problem 
(enable_gpl_third_parties=no or enable_zrtp=no).
Reading this support group I was able to pass this point by editing 
builder-iphone-os.mk directly and removing zrtpcpp:

#SUBMODULES_LIST := polarssl libantlr belle-sip srtp zrtpcpp speex libgsm 
libvpx libxml2 ffmpeg opus
SUBMODULES_LIST := polarssl libantlr belle-sip srtp speex libgsm libvpx libxml2 
ffmpeg opus

After this change, make veryclean && make all stops on speex:

/bin/sh ../libtool  --tag=CC   --mode=link xcrun clang -std=c99  -arch i386  
-isysroot

Any help is appreciated.
