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

[BIENKOWSKI Guillaume]

Hello,

That's good investigation you did there, but sadly we can't maintain compatible config.site files for too old versions of Mac OS / XCode.

I can give you a bit more comments though:

- for the libvpx configure.sh, you could integrate your changes in the patch that is applied by our build script. You'll find the patch in submodules/build/builders.d/libvpx.patch.

This will save you the burden of modifying it everytime.

- The ffmpeg issue seems to be linked to a bug in llvm frontend. Are you certain that GCC was used at that point? And not llmv-gcc? You might have more luck with :

CC="gcc -std=c99 $COMMON_FLAGS"
OBJC="gcc -std=c99 $COMMON_FLAGS"
CXX="g++ $COMMON_FLAGS"

But I'm not absolutely sure here.

Good lock

Guillaume, thanks for your prompt reply.

Switching from clang to gcc helped me to build using XCode 4.2 on SL 10.6.8.
I also had to disable zrtp and ffmpeg - Later I'll investigate this issue - as for now VP8 is fine for me.

Follows what I had to do in order to build using a fresh SL 10.6.8 install + XCode 4.2:

- Get the source
git clone git://git.linphone.org/linphone-iphone.git --recursive

- Prepare the environment as explained in README

- Edit submodules/build/iphone-config.site (1):

CC="xcrun gcc -std=c99 $COMMON_FLAGS"
OBJC="xcrun gcc -std=c99 $COMMON_FLAGS"
CXX="xcrun g++ $COMMON_FLAGS"

- Edit submodules/build/builder-iphone-os.mk and remove zrtpcpp (2) and ffmpeg (3):

#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 opus

- Build for simulator:
make -f builder-iphone-simulator.mk enable_gpl_third_parties=no enable_zrtp=no enable_ffmpeg=no all

- Create symlinks to arm-apple-darwin10-llvm-g??-4.2 compiler (4):
sudo ln -s /Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2  /Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2
sudo ln -s /Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-g++-4.2  /Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-g++-4.2

- Edit submodules/externals/libvpx/build/configure.sh (5):
Note that before changing it, configure.sh needs to get patched by simulator build.
For every make veryclean, these changes need to be applied again.

#CXX=`xcrun --find clang++`
CXX="xcrun g++"
#CC=`xcrun --find clang`
CC="xcrun gcc"
#LD=`xcrun --find clang`
LD="xcrun gcc"

- Finish building:
make -f builder-iphone-os.mk enable_gpl_third_parties=no enable_zrtp=no enable_ffmpeg=no all \
&& make -f builder-iphone-os.mk delivery-sdk

NOTES:
(1) First clue that clang was "old" in SL10.6.8/XCode 4.2:

libtool: link: xcrun clang -std=c99 -arch i386 -isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk -miphoneos-version-min=4.0 -DTARGET_OS_IPHONE=1 -D__IOS -fms-extensions -O2 -fvisibility=hidden -o testenc testenc.o  ./.libs/libspeex.a ./.libs/libspeexdsp.a -lm

(2) Even if enable_zrtp=no is specified, it still tries to compile it, giving the following errors:

(3) Even if enable_ffmpeg=no is specified, it still tries to compile it, giving the following errors:

Hello,

I suspect the clang executable is a bit too old on these versions.

Could you try changing the

CC="xcrun clang -std=c99 $COMMON_FLAGS"
OBJC="xcrun clang -std=c99 $COMMON_FLAGS"
CXX="xcrun clang++ $COMMON_FLAGS"

in submodules/build/iphone-config.site to :

CC="xcrun gcc -std=c99 $COMMON_FLAGS"
OBJC="xcrun gcc -std=c99 $COMMON_FLAGS"
CXX="xcrun g++ $COMMON_FLAGS"

And a veryclean / make ?

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:

(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 /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk -miphoneos-version-min=4.0 -DTARGET_OS_IPHONE=1 -D__IOS -fms-extensions  -O2 -fvisibility=hidden   -o testenc testenc.o libspeex.la libspeexdsp.la  -lm

make[3]: *** [all-recursive] Error 1
make[2]: *** [all] Error 2

Any help is appreciated.
